RESUMO
OBJECTIVE: To evaluate the effect of entrapment of curcumin within liposomal formulation and the sustained release attitude of the formulated liposomal gel on periodontal defects in diabetic patients in clinical and biochemical terms. METHODS: Thirty diabetic patients with periodontitis were randomly assigned to three equal groups and ten healthy participants were assigned as the control group. Group I was subjected to scaling and root planing (SRP) with application of sustained release liposomal curcumin gel. Group II was subjected to scaling and root planning with application of curcumin gel. Group III was subjected to scaling and root planning with application of placebo gel. Group IV (control group), no intervention was done. The following parameters were evaluated before treatment and after 6 and 12 weeks: plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), tumour necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1ß) and total antioxidant capacity (TAC). RESULTS: All study groups showed improvement in clinical and biochemical parameters that are statistically significant. Upon comparing the results of treatment modalities, the highest improvement was achieved in group I followed by group II then group III. CONCLUSION: Sustained release liposomal curcumin gel enhanced the antioxidant capacity, decreased the inflammatory mediators and showed more improvement in clinical outcome for treatment of periodontitis in diabetic patients.

BACKGROUND: Periodontitis and peri-implant diseases are chronic inflammatory conditions occurring in the mouth. Left untreated, periodontitis progressively destroys the tooth-supporting apparatus. Peri-implant diseases occur in tissues around dental implants and are characterised by inflammation in the peri-implant mucosa and subsequent progressive loss of supporting bone. Treatment aims to clean the pockets around teeth or dental implants and prevent damage to surrounding soft tissue and bone, including improvement of oral hygiene, risk factor control (e.g. encouraging cessation of smoking) and surgical interventions. The key aspect of standard non-surgical treatment is the removal of the subgingival biofilm using subgingival instrumentation (SI) (also called scaling and root planing). Antimicrobial photodynamic therapy (aPDT) can be used an adjunctive treatment to SI. It uses light energy to kill micro-organisms that have been treated with a light-absorbing photosensitising agent immediately prior to aPDT. OBJECTIVES: To assess the effects of SI with adjunctive aPDT versus SI alone or with placebo aPDT for periodontitis and peri-implant diseases in adults. SEARCH METHODS: We searched the Cochrane Oral Health Trials Register, CENTRAL, MEDLINE, Embase, two other databases and two trials registers up to 14 February 2024. SELECTION CRITERIA: We included randomised controlled trials (RCTs) (both parallel-group and split-mouth design) in participants with a clinical diagnosis of periodontitis, peri-implantitis or peri-implant disease. We compared the adjunctive use of antimicrobial photodynamic therapy (aPDT), in which aPDT was given after subgingival or submucosal instrumentation (SI), versus SI alone or a combination of SI and a placebo aPDT given during the active or supportive phase of therapy. DATA COLLECTION AND ANALYSIS: We used standard Cochrane methodological procedures, and we used GRADE to assess the certainty of the evidence. We prioritised six outcomes and the measure of change from baseline to six months after treatment: probing pocket depth (PPD), bleeding on probing (BOP), clinical attachment level (CAL), gingival recession (REC), pocket closure and adverse effects related to aPDT. We were also interested in change in bone level (for participants with peri-implantitis), and participant satisfaction and quality of life. MAIN RESULTS: We included 50 RCTs with 1407 participants. Most studies used a split-mouth study design; only 18 studies used a parallel-group design. Studies were small, ranging from 10 participants to 88. Adjunctive aPDT was given in a single session in 39 studies, in multiple sessions (between two and four sessions) in 11 studies, and one study included both single and multiple sessions. SI was given using hand or power-driven instrumentation (or both), and was carried out prior to adjunctive aPDT. Five studies used placebo aPDT in the control group and we combined these in meta-analyses with studies in which SI alone was used. All studies included high or unclear risks of bias, such as selection bias or performance bias of personnel (when SI was carried out by an operator aware of group allocation). We downgraded the certainty of all the evidence owing to these risks of bias, as well as for unexplained statistical inconsistency in the pooled effect estimates or for imprecision when evidence was derived from very few participants and confidence intervals (CI) indicated possible benefit to both intervention and control groups. Adjunctive aPDT versus SI alone during active treatment of periodontitis (44 studies) We are very uncertain whether adjunctive aPDT during active treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (mean difference (MD) 0.52 mm, 95% CI 0.31 to 0.74; 15 studies, 452 participants), BOP (MD 5.72%, 95% CI 1.62 to 9.81; 5 studies, 171 studies), CAL (MD 0.44 mm, 95% CI 0.24 to 0.64; 13 studies, 414 participants) and REC (MD 0.00, 95% CI -0.16 to 0.16; 4 studies, 95 participants); very low-certainty evidence. Any apparent differences between adjunctive aPDT and SI alone were not judged to be clinically important. Twenty-four studies (639 participants) observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. Adjunctive aPDT versus SI alone during supportive treatment of periodontitis (six studies) We were very uncertain whether adjunctive aPDT during supportive treatment of periodontitis leads to improvement in any clinical outcomes at six months when compared to SI alone: PPD (MD -0.04 mm, 95% CI -0.19 to 0.10; 3 studies, 125 participants), BOP (MD 4.98%, 95% CI -2.51 to 12.46; 3 studies, 127 participants), CAL (MD 0.07 mm, 95% CI -0.26 to 0.40; 2 studies, 85 participants) and REC (MD -0.20 mm, 95% CI -0.48 to 0.08; 1 study, 24 participants); very low-certainty evidence. These findings were all imprecise and included no clinically important benefits for aPDT. Three studies (134 participants) reported adverse effects: a single participant developed an abscess, though it is not evident whether this was related to aPDT, and two studies observed no adverse effects related to aPDT (moderate-certainty evidence). No studies reported pocket closure at six months, participant satisfaction or quality of life. AUTHORS' CONCLUSIONS: Because the certainty of the evidence is very low, we cannot be sure if adjunctive aPDT leads to improved clinical outcomes during the active or supportive treatment of periodontitis; moreover, results suggest that any improvements may be too small to be clinically important. The certainty of this evidence can only be increased by the inclusion of large, well-conducted RCTs that are appropriately analysed to account for change in outcome over time or within-participant split-mouth study designs (or both). We found no studies including people with peri-implantitis, and only one study including people with peri-implant mucositis, but this very small study reported no data at six months, warranting more evidence for adjunctive aPDT in this population group.

PURPOSE: To evaluate the efficacy of the adjunctive use of tea tree oil (TTO) for dental plaque control and nonsurgical periodontal treatment (NSPT). MATERIALS AND METHODS: Three electronic databases were searched from 2003. The reference lists of the included articles and relevant reviews were also manually searched. Randomised controlled trials reporting the clinical outcomes of the topical use of TTO as an adjunct to daily oral hygiene or scaling and root planing (SRP) were included. Regarding the use of TTO as an adjunctive to daily oral hygiene, the primary outcome was plaque index (PI) reduction. Regarding the use of TTO as an adjunctive to SRP, probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain were the primary outcomes. The secondary outcomes were adverse events. RESULTS: Eleven studies were included for qualitative analysis, 9 studies were included for quantitative analysis, and 6 studies were included to examine the application of TTO mouthwash as an adjunctive to daily oral hygiene. In addition, three studies were included to analyse the subgingival use of TTO adjunctive to SRP at selected sites. The results indicated a nonsignificant improvement in PI reduction in the TTO mouthwash group compared with placebo. The incidence of adverse events was statistically significantly greater in the CHX group than in the TTO group. For subgingival use of TTO adjunctive to SRP, beneficial effects were observed in the TTO group compared with SRP alone in terms of PPD and CAL at both three and six months post-treatment. However, an unpleasant taste was reported in three out of four studies. CONCLUSION: There is a lack of strong evidence to support the beneficial effects of TTO. Studies with larger sample sizes and standardised evaluation criteria are needed to further demonstrate the clinical relevance of TTO.

Background and Objectives: This paper aims to assess the role of laser therapy in periodontitis through an innovative approach involving computational prediction and advanced modeling performed through network analysis (Gaussian graphical models-GGMs) and structural equations (SEM). Materials and Methods: Forty patients, exhibiting periodontal pockets with a minimum depth of 5 mm, were randomly divided into two groups: a control group and a laser group. Four specific indicators were measured for each tooth, namely periodontal pocket depth (PPD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI), and the mean of six measured values was recorded at five time markers (baseline, 6 months, 1 year, 2 years, and 4 years). The assessment algorithm included enrollment, measurements, and differential non-surgical periodontal treatment, according to the group allocation. Scaling, root planing, and chlorhexidine 1% were conducted for the control group, and scaling, root planing and erbium, chromium:yttrium-scandium-gallium-garnet (Er,CR:YSGG) laser therapy were conducted for the laser group. Results: The main results highlight that the addition of laser treatment to scaling and root planing led to notable clinical improvements, decreasing the PPD values, reducing the BOP scores, and increasing the CAL. Conclusions: Notable relationships between the specific indicators considered were highlighted by both the GGMs and by SEM, thus confirming their suitability as proxies for the success of periodontal treatment.

BACKGROUND: Periodontal disease poses a significant global health challenge. Traditional treatments focus on reducing inflammation and bacterial load, yet novel approaches are continually being investigated. Recent research suggests that IL-37, a potent anti-inflammatory cytokine, may play a crucial role in modulating the inflammatory processes associated with periodontal disease. In conjunction with IL-37, low-level laser therapy (LLLT) has gained attention for its potential in promoting tissue repair, reducing inflammation, and enhancing cellular processes. This study aims to investigate the effects of LLLT on IL-37 in periodontal disease management. METHODS: Thirty patients were enrolled: the G1 group patients were treated with only scaling and root planning-SRP, the G2 group was treated with SRP and LLLT. Before treatment (T0) all periodontal probing pocket depth and bleeding on probing were obtained. Before (T0) and 10 (T1), 30 (T2) and 60 (T3) days after treatment, was achieved plaque sample and specimens of gingival crevicular fluid. Diode laser wavelength range was used between 600-1000 nm and 0.04-60 J/cm2 energy density for 3-s spotlights. RESULTS: In all patients PPD, BOP and IL-37 have shown healing improved parameters. CONCLUSIONS: Although LLLT is widely recommended for its biostimulatory and anti-inflammatory roles, it only showed additional short-term merits in reducing the pocket depth after conventional SRP. Its long-term adjunctive benefits remain unclear. Future RCTs with better study designs, adequate sample power and longer durations of follow-up are required to assess the effectiveness of LLLT as an adjunctive treatment strategy in patients with periodontal disease.

OBJECTIVE: The study aims to determine the effects of Nd:YAG laser-assisted with subgingival scaling and root planing (SRP) treatment on glucose control and the dynamic changes of subgingival microbiome in periodontitis with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: Twenty-two patients were split into Nd:YAG group (n = 11) and SRP group (n = 11). Patients in the Nd:YAG group received SRP and auxiliary Nd:YAG laser treatment; patients in the SRP group received SRP treatment only. Periodontal tissue inflammation and glycemic control were assessed and analyzed during the treatment period and the changes of subgingival microbiome were analyzed by full-length 16S rRNA sequencing. RESULTS: After 3 months of treatment, PD and CAL values improved significantly in the Nd:YAG group compared to the SRP group. BOP in both groups improved significantly after treatment. FPG levels in the Nd:YAG group were significantly reduced after treatment. Porphyromonas and Porphyromonadaceae were enriched in the Nd:YAG group at baseline, and Fusobacteriota, Fusobacteriia, Fusobacteriales, Leptotrichiaceae, and Leptotrichia were enriched after treatment. CONCLUSION: Nd:YAG laser-assisted SRP therapy has additional benefits in improving periodontal tissue inflammation and blood glucose control in periodontitis patients with T2DM compared with SRP therapy alone and there was a trend towards a decrease in disease-associated taxa and an increase in health-associated taxa following auxiliary Nd:YAG laser treatment. CLINICAL RELEVANCE: The effects of Nd:YAG laser-assisted SRP treatment on inflammation, glucose control, and subgingival microbiome in periodontitis patients with T2DM were elucidated, and new ideas for the treatment of T2DM periodontitis were provided.

BACKGROUND: The main aim of periodontal therapy is to halt the progression of periodontitis. Curcumin, one of the main components of Curcumin longa, has been well known to possess antimicrobial, anti-inflammatory, and even anticarcinogenic properties. This systematic review assessed the impact of local application of curcumin in the pocket on the clinical and microbiologic parameters as an adjunct to scaling and root planing in periodontitis patients. METHODS: The electronic literature search retrieved 61 studies from PubMed, MEDLINE, and ScienceDirect. After screening titles, abstracts, and keywords and reading through these articles, we identified 9 articles meeting all inclusion criteria, which were included for systematic review. RESULTS: There was a significant difference in both clinical parameters in a short duration of a month after curcumin chips were placed as an adjunct to scaling and root planing as compared to the control. Local application of curcumin also results in slight to significant reduction in the red complex microorganisms. CONCLUSION: This review suggested that local application of curcumin can be considered as a viable adjunct to mechanical debridement in periodontitis. However, further studies need to be conducted to establish its optimum dose, delivery method, and frequency in achieving the best clinical outcomes.

AIM: This split-mouth randomized trial (RCT) aimed to assess the effect of diode laser on the clinical parameters in patients with periodontitis, compare the results with scaling and root planing (SRP) alone, and assess the implications of diode laser (DL) on plaque bacteria. MATERIALS AND METHODS: Seventeen periodontitis patients were randomly assigned into two equal groups based on the therapy delivered. Group I (control site) received just SRP at baseline, while group II (test site) received both SRP and DL irradiation. For both groups, the clinical periodontal parameters probing pocket depth (PPD), and clinical attachment level (CAL) were measured at baseline, 30 days, and 90 days. Microbiological amount was also measured at baseline, 30, and 90 days after periodontal treatment. The amounts of Aggregatibacter actinomycetemcomitans (A.a), Prevotella intermedia (Pr. intermedia), and Porphyromonas gingivalis (P. gingivalis) were determined using real-time PCR probing with specific bacterial primers. RESULTS: In both groups, PPD and CAL showed statistically significant reductions at different time intervals (p < 0.05). No significant difference were observed in CAL values after 1 and 3 months in both test and control groups (p > 0.05). The mean values of the concentration of A.a, Pr. intermedia and P. gingivalis were lower in the case group as compared to the control group and the difference was statistically significant after 1 month (*p = 0.001). CLINICAL SIGNIFICANCE: According to this study, non-invasive laser treatment has the potential to improve clinical outcomes by lowering the quantity of A.a, Pr. intermedia and P. gingivalis. CONCLUSION: In both groups, a considerable decrease in the periodontal pathogens A.a, Pr. intermedia and P. gingivalis were discovered; however, the intergroup comparison was insignificant in relation to PD and CAL. The adjunctive treatment with diode laser showed better efficacy in ensuring a better periodontal treatment than SRP alone. How to cite this article: Abdullah LA, Hashim N, Rehman MM, et al.

O propósito do estudo foi avaliar a efetividade da raspagem e alisamento radicular (RAR) associado à coenzima Q10 (CQ10) administrada localmente e/ou sistemicamente no tratamento da periodontite experimental (PE) em ratos tratados sistemicamente com nicotina (NIC). 128 ratos (Wistar) foram divididos em oito grupos (n=16). Durante todo o período experimental, os animais receberam duas injeções subcutâneas diárias de 3mg/kg de hemissulfato de nicotina ou solução salina (SS) na região dorsal, com 12 horas de intervalo entre elas, começando nos 30 dias que antecederam à indução da PE. Após 15 dias da indução da PE, o protocolo de RAR foi realizado bem como o tratamento coadjuvante local e/ou sistêmico com CQ10, com e sem tratamento com a NIC, sendo: SS-PE-RAR e NIC-PE-RAR: irrigação subgengival com SS; SS-PE-RAR/Q10L e NIC-PE-RAR/Q10L: irrigação subgengival com 1ml solução de CQ10; SS-PE-RAR/Q10S e NIC-PE-RAR/Q10S: gavagem gástrica diária com 120 mg de CQ10; SS-PE-RAR/Q10LS e NIC-PE-RAR/Q10LS: irrigação subgengival com 1ml solução de CQ10 e gavagem gástrica diária com 120 mg de CQ10. As eutanásias foram realizadas 7 e 28 dias após tratamento. As peças coletadas foram processadas com desmineralização para as análises histopatológica, histométrica e imunoistoquímica para detecção de TRAP. Os dados foram submetidos ao teste paramétrico Anova two-way e pós-teste de Tukey. O nível de significância adotado foi de 5% (p≤0,05). Na análise histopatológica, pode-se observar que os grupos NIC-PE-RAR-Q10L E NIC-PE-RAR-Q10LS apresentaram tecidos periodontais com aspecto de normalidade, com preservação da inserção conjuntiva e de região de furca preservada aos 7 e 28 dias, de modo distinto do grupo NIC-PE-RAR e NIC-PE-RAR-Q10S em ambos os períodos. Na análise histométrica, pode-se observar maior porcentagem de osso na furca (POF) (p≤0,05) nos grupos NIC-PE-RAR-Q10L, NIC-PE-RAR-Q10S e NIC-PERAR-Q10LS em comparação com o grupo NIC-PE-RAR em ambos os períodos e também com o grupo SS-PE-RAR aos 28 dias. Pode-se observar menor número de células TRAP positivas (p≤0,05) no grupo NIC-PE-RAR-Q10L quando comparado aos grupos SS-PE-RAR E NIC-PE-RAR aos 7 dias e no grupo NIC-PE-RAR-Q10LS quando comparado aos mesmos grupos aos 28 dias. Conclui-se que RAR associado à CQ10 utilizada local e local/sistemicamente no tratamento da PE em ratos tratados sistemicamente com nicotina foram efetivas mostrando resultados favoráveis nas análises histopatológica, histométrica e imunoistoquímica(AU)
The aim of this study was to evaluate the effectiveness of scaling and root planing (SRP) combined with adjunctive local and/or systemic administration of coenzyme Q10 (CQ10) for the treatment of experimental periodontitis (EP) in rats systemically treated with nicotine (NIC). 128 Wistar rats were divided into 8 groups (n=16). Throughout the experiment, animals received two subcutaneous injections of either 3mg/kg nicotine hemissulfate or physiological saline solution (PSS) with 12 h interval between them. These injections were initiated 30 days prior EP induction. 15 days after EP induction, the protocol for SRP was performed together (or not) with local and/or systemic adjunctive CQ10 administration in animals treat with either NIC or PSS, as described: PSS-EP-SRP and NIC-EP-SRP: subgingival irrigation with PSS; PSS-EP-SRP/Q10L and NIC-EP-SRP/Q10L: subgingival irrigation with 1ml of CQ10 solution; PSS-EP-SRP/Q10S and NIC-EP-SRP/Q10S: daily gastric gavage with 120 mg of CQ10; PSS-EP-SRP/Q10LS and NIC-EP-SRP/Q10LS: subgingival irrigation with 1ml of CQ10 solution and daily gastric gavage with 120 mg of CQ10. The euthanasia was performed at 7 and 28 days after treatment. The specimens were collected and processed for histopathologic, histometric and immunochemical for of TRAP analyzes. The data were submitted to the two-way ANOVA and Tukey's post-test. The level of significance adopted was 5% (p≤0.05). In the histopathological analysis, it can be observed that the NIC-PE-RAR-Q10L and NIC-PE-RAR-Q10LS groups presented periodontal tissues with normal aspect, preserving the conjunctival insertion and furca region preserved at 7 and 28 days, differently from the NIC-PE-RAR and NIC-PE-RAR-Q10S groups in both periods. In histometric analysis, a higher percentage of bone in furca (PBF) (p≤0.05) can be observed in the NIC-PE-RAR-Q10L, NIC-PE-RAR-Q10S and NIC-PE-RAR-Q10LS groups compared to the NIC-PE-RAR group in both periods and also with the SS-PE-RAR group at 28 days. A lower number of TRAPpositive cells (p≤0.05) can be observed in the NIC-PE-RAR-Q10L group when compared to the SS-PE-RAR and NIC-PE-RAR groups at 7 days and in the NIC-PE-RAR-Q10LS group when compared to the same groups at 28 days. It was concluded that RAR associated with CQ10 used locally and locally/systemically in the treatment of EP in rats treated systemically with NIC were effective, showing favorable results in histopathological, histometric and immunohistochemical analyses(AU)

O presente estudo teve a finalidade de avaliar os efeitos do uso do probiótico (PRO) Saccharomyces ceveriseae coadjuvante à raspagem e alisamento radicular (RAR) no tratamento da periodontite experimental (PE) induzida em animais imunossuprimidos com o quimioterápico 5-Fluorouracil (5FU). Cento e oito animais foram submetidos à indução da PE por meio da instalação de um fio de algodão ao redor do primeiro molar inferior esquerdo ou direito. A imunossupressão foi obtida pela injeção intraperitoneal do 5FU aplicada em dois momentos: no ato da instalação da ligadura e após 48 horas. Sete dias após instalação a ligadura foi removida e os animais separados aleatoriamente em seis grupos experimentais que receberam os seguintes tratamentos: PE (n=18) - animais que não sofreram nenhum tratamento sistêmico ou local; SS (n=18) - animais que não sofreram tratamento local, apenas tratamento sistêmico com solução salina (SS); 5FU (n=18) - animais tratados sistemicamente com 5FU que não sofreram nenhum tratamento local; 5FU-PRO (n=18) - animais tratados sistemicamente com 5FU que receberam irrigação local com 0,6 ml de PRO; 5FURAR (n=18) - animais tratados sistemicamente com 5FU que receberam RAR e; 5FURAR-PRO (n=18) - animais tratados sistemicamente com 5FU, que receberam tratamento com RAR e irrigação local com 0,6 ml de PRO. Seis animais de cada período foram submetidos à eutanásia aos 7, 15 e 30 dias após os tratamentos. Os espécimes contendo a área interessada foram obtidos e processados para a análise histopatológica, histométrica da perda óssea alveolar (POA), porcentagem de tecido ósseo (PTO), porcentagem de osso vital (POV) e porcentagem de osso não vital (PONV), e análise imunoistoquímica (TRAP, RANKL e OPG). Os dados obtidos foram submetidos à análise estatística (α=5%). Os resultados histológicos demonstraram que nos espécimes tratados com 5FU houve agravamento da perda óssea na região de furca comparado com os animais sistemicamente saudáveis (grupos PE e SS); que o tratamento com PRO como monoterapia (grupo 5FU-PRO) promoveu redução do processo inflamatório, denotando estabilização da doença periodontal; que o tratamento com RAR (grupo 5FU-RAR) reduziu o volume do infiltrado inflamatório mostrando sinais de reparação e a associação PRO-RAR (grupo 5FU-RAR-PRO) evidenciou nítida reestruturação tecidual aos 15 dias e menor área de reabsorção óssea aos 30 dias. Observou-se na análise histométrica que a POA foi maior no grupo 5FU-PRO em relação ao grupo SS aos 30 dias (p<0,05); a PTO foi maior no grupo 5FU-RAR-PRO aos 30 dias em comparação aos grupos EP, SS, 5FU e 5FU-PRO (p<0,05) e a POV foi maior no grupo 5FU-RAR-PRO em comparação ao grupo 5FU aos 7 dias, e maior aos 30 dias em comparação a todos os grupos experimentais (p<0,05). Não houve diferença entre os grupos e períodos na imunomarcação das células TRAP positivas. A RANKL mostrou alto padrão de imunomarcação nos grupos PE, SS e 5FU em todos períodos, e aos 7 dias no grupo 5FU-PRO, 5FU-RAR e 5FURAR-PRO, moderado padrão de imunomarcação nos grupos 5FU, 5FU-PRO, 5FURAR, e 5FU-RAR-PRO, mantendo-se baixo padrão neste último grupo, no período de 30 dias. Houve baixo padrão de imunomarcação de OPG em todos os grupos e períodos, exceto no grupo 5FU-RAR-PRO que mostrou moderado padrão. Diante dos resultados obtidos pode ser concluído que o uso do quimioterápico 5FU agravou a PE; que o uso do Saccharomyces ceveriseae associado à RAR, minimizou os efeitos do quimioterápico nos tecidos periodontais reduzindo o processo inflamatório, e reduzindo a porcentagem de destruição de tecido ósseo na área de furca em animais imunossuprimidos(AU)
The present study aimed to evaluate the effects of using probiotic (PRO) Saccharomyces ceveriseae as an adjuvant of scaling and root planing (SRP) in the treatment of experimental periodontitis (EP) induced in immunosuppressed animals with chemotherapeutic 5-Fluorouracil (5FU). One hundred and eight animals were submitted to EP induction by installing a cotton thread around the lower left or right first molar. Immunosuppression was obtained by intraperitoneal injection of 5FU applied in two moments: at the time of installing the ligature and after 48 hours. Seven days after installation, the ligature was removed and the animals were randomly separated into six experimental groups that received the following treatments: EP (n = 18) - animals that did not receive any systemic or local treatment; SS (n = 18) - animals that did not receive local treatment, only systemic treatment with saline solution (SS); 5FU (n = 18) - animals treated systemically with 5FU that did not receive any local treatment; 5FUPRO (n = 18) - animals treated systemically with 5FU that received local irrigation with 0.6 ml of PRO; 5FU-SRP (n = 18) - animals treated systemically with 5FU that received RAR and; 5FU-SRP-PRO (n = 18) - animals treated systemically with 5FU, which received treatment with SRP and local irrigation with 0.6 ml of PRO. Six animals from each period were euthanized at 7, 15 and 30 days after treatments. The specimens containing the interested area were obtained and processed for histopathological, histometric analysis of alveolar bone loss (ABL), percentage of bone tissue (PBT), percentage of vital bone (PVB) and percentage of non-vital bone (PNVB), and immunohistochemical analysis (TRAP, RANKL and OPG). The data obtained were subjected to statistical analysis (α = 5%). The histological results showed that in the specimens treated with 5FU there was worsening of bone loss in the furcation region compared to healthy animals (EP and SS groups); that treatment with PRO as monotherapy (group 5FU-PRO) reduced the inflammatory process, denoting stabilization of periodontal disease; that treatment with SRP (5FU-SRP group) reduced the volume of the inflammatory infiltrate showing signs of repair and the PRO-SRP association (5FU-SRP-PRO group) showed a clear tissue restructuring at 15 days and a smaller area of bone resorption at 30 days. It was observed in the histometric analysis that ABL was higher in the 5FU-PRO group compared to SS group at 30 days (p <0.05); PTO was higher in 5FU-SRP-PRO group at 30 days compared to EP, SS, 5FU and 5FU-PRO groups (p <0.05) and PVB was higher in the 5FU-SRP-PRO group compared to 5FU group at 7 days, and greater at 30 days compared to all experimental groups (p <0.05). There was no difference between groups and periods in the immunostaining of TRAP positive cells. RANKL showed a high immunostaining pattern in the EP, SS and 5FU groups in all periods, and at 7 days in 5FU-PRO, 5FU-SRP and 5FU-SRP-PRO groups, a moderate immunostaining pattern in the 5FU, 5FU-PRO, 5FU-SRP and 5FU-SRP-PRO groups, maintaining a low standard in 5FU-SRP-PRO group, in the period of 30 days. There was a low pattern of OPG immunostaining in all groups and periods, except in 5FU-SRP-PRO group, which showed a moderate pattern. In view of the results obtained, it can be concluded that the use of 5FU chemotherapy has worsened the evolution of EP; that the use of Saccharomyces ceveriseae associated with RAR, minimized the effects of chemotherapy on periodontal tissues, reducing the inflammatory process, and reducing the percentage of bone tissue destruction in the furcation area in immunosuppressed animals(AU)

Abstract Periodontal therapy usually requires local anesthesia. If effective, a non-invasive, liposomal anesthetic gel could increase the levels of acceptance of patients in relation to periodontal therapy. Objective: This study investigated the efficacy of liposomal anesthetic gel for pain control during periodontal therapy. Methodology: Forty volunteers with moderate to severe chronic periodontitis were recruited, of which at least three sextants required periodontal therapy. At least one of the selected teeth had one site with a probing depth of ≥4 mm. The volunteers received the following three gels: a placebo, lidocaine/prilocaine (Oraqix®), or a liposomal lidocaine/prilocaine, which were applied to different sextants. Pain frequency was registered during treatment and the volunteers received a digital counter to register any painful or uncomfortable experiences. At the end of each session, the volunteers indicated their pain intensity using rating scales (NRS-101 and VRS-4). The volunteers had their hemodynamic parameters measured by a non-invasive digital monitor. Results: Pain frequency/intensity did not show statistical difference between intervention groups. The tested gels did not interfere with the hemodynamic indices. Dental anxiety, suppuration and probing depth could influence pain during periodontal therapy. Conclusion: Our results suggest limited indications for the use of non-invasive anesthesia when used for scaling and root planing. Intra-pocket anesthetic gel could be a good option for anxious patients, or those who have a fear of needles.

Abstract The evidence is inconclusive regarding the effect of periodontal treatment on glycemic control and systemic inflammation in patients with type 2 diabetes (T2D) and periodontitis Objective: To evaluate the effect of scaling and root planing (SRP) on the metabolic control and systemic inflammation of patients with type 2 diabetes (T2D). Methodology: A literature search was conducted using the MEDLINE database via PubMed and the Cochrane Central Register of Controlled Trials, from their oldest records up to July 2018. Only randomized clinical trials (RCT) were considered eligible for evaluating the effect of periodontal treatment on markers of metabolic control [glycated hemoglobin (HbA1C)] and systemic inflammation [C-reactive protein (CRP)] in patients with T2D. The quality of the studies was evaluated using the Cochrane Collaboration risk assessment tool. Meta-analyses were performed for HbA1c and CRP using random effects models. The size of the overall intervention effect was estimated by calculating the weighted average of the differences in means (DM) between the groups in each study. Heterogeneity was assessed using the Q-statistic method (x2 and I²). The level of significance was established at p<0.05. Results: Nine RCT were included. SRP was effective in reducing HbA1c [DM=0.56 (0.36-0.75); p<0.01] and CRP [DM=1.89 (1.70-2.08); p<0.01]. No heterogeneity was detected (I2=0%, p>0.05). Conclusions: SRP has an impact on metabolic control and reduction of systemic inflammation of patients with T2D.

Abstract Objective: To evaluate the accuracy of cone-beam computed tomography (CBCT) in the assessment of mandibular molar furcation defects. Material and Methods: Thirty patients with furcation defects were selected, oral hygiene instructions, scaling, and root planing with ultrasonic devices and hand instruments and occlusal adjustments were performed. Pre-surgical clinical measurements were carried out at the buccal aspect of the selected mandibular molars. The horizontal furcation measurements were measured with a Nabers Probe starting at the furcation entrance to the greatest horizontal depth. The degree of furcation involvement was graded from 0 to III. Bone loss in the horizontal and vertical direction and the width of the furcation entrance were measured on CBCT and after reflecting the full-thickness flap and debridement of the defects. The data were analyzed using t-test and Pearson's correlation coefficient. Results: The width of furcation entrance in clinical method was 3.27 ± 0.77, while in CBCT method was 3.35 ± 0.71, clinically the vertical bone loss was 3.61±1.09, while in CBCT was 3.57 ± 1.15, horizontal bone loss in clinical method was 5.08 ± 2.21, while in CBCT was 5.11 ± 2.23. No significant difference between the two methods was noted, and a high correlation between the two methods was observed. With regards to the agreement between the two methods of assessment, the width of furcation entrance revealed a difference between the two methods by 0.08 ± 0.21, while vertical bone loss showed difference between the two methods by -0.04 ± 0.19, the horizontal bone loss showed a mean difference between the two methods by 0.03 ± 0.21. Conclusion: CBCT provided high accuracy for the furcation involvement detection and anatomy of surrounding periodontal tissues.

La instrumentación mecánica durante el tratamiento periodontal trae consigo la formación de escombros microcristalinos que inhiben la adhesión tisular a la superfi cie radicular y favorece la proliferación bacteriana, lo cual perjudica los resultados del tratamiento periodontal a corto y largo plazo. Hoy en día el acondicionamiento radicular con el uso de biomodifi cadores es una opción de tratamiento adicional en el tratamiento de la periodontitis y el tratamiento de cobertura radicular. El objetivo del presente estudio es realizar una revisión de la literatura acerca de las aplicaciones y del acondicionamiento radicular con ácido cítrico, tetraciclina, EDTA y láser en el tratamiento periodontal no quirúrgico y quirúrgico (AU)
Mechanical instrumentation during periodontal treatment brings the formation of microcrystalline debris that inhibits tissue adhesion to the root surface and favors bacterial proliferation, which harms the results of the short and long term periodontal treatment. Nowadays, root conditioning with the use of biomodifi cators is an additional treatment option in the treatment of periodontitis and root coverage therapy. The aim of the present study is to conduct a literature review about the applications and the root conditioning with citric acid, tetracycline, EDTA and laser in the non surgical and surgical periodontal treatment (AU)

Abstract The effectiveness of azithromycin combined with full-mouth scaling procedures was compared to quadrant-wise scaling combined with the same dosage of azithromycin when treating periodontitis patients over a 6-month period. In this randomized clinical trial study, thirty-four individuals diagnosed with generalized stage III and IV periodontitis underwent baseline, 3-month, and 6-month post-treatment examinations. The study population was randomly assigned to either full-mouth scaling (FMS) or quadrant-wise scaling and root planning (QSRP) in addition to their taking of systemic azithromycin (500 mg/day) for three consecutive days. Periodontal probing depth (PD), clinical attachment level (CAL), gingival index (GI), and plaque index (PI) were monitored along with the quantification of total bacterial load and red complex bacterial species (Porphyromonas gingivalis, Tannerella forsythia, and Treponema denticola) in subgingival samples by real time polymerase chain reaction. The volume of gingival crevicular fluid (GCF) was also monitored over time. The primary outcomes included improvements of PD and CAL. Data was statistically analyzed through a repeated-measures analysis of variance (ANOVA) test, multiple least significant difference (LSD) comparisons, Kruskal-Wallis, Friedman, and paired Student t-tests (p<0.05). FMS and QSRP provided similar PD, CAL, GI, PI, and GCF improvements. After treatment, the FMS group displayed lower mean values of total bacterial load and red complex bacterial species in comparison to the QSRP group. FMS and QSRP in conjunction with systemic azithromycin appeared to be an effective and reliable short-term therapeutic approach for the treatment of generalized stage III and IV periodontitis. However, FMD demonstrated superiority in regard to the 6-month antibacterial effects when compared to QSRP.
Resumo A efetividade da azitromicina combinada com a técnica de desinfecção total da boca (DTB) foi comparada a raspagem por quadrante (RQ) utilizando a mesma dosagem de azitromicina no tratamento de indivíduos com periodontite generalizada estágio III e IV, em um período de 6 meses. Trinta e quatro indivíduos foram submetidos aos exames no baseline, 3 e 6 meses pós-tratamento. A população estudada foi alocada aleatoriamente no grupo DTB ou RQ associado a três dias consecutivos de azitromicina (500 mg/dia). Profundidade de sondagem (PS), nível clínico de inserção (NIC), índice gengival (IG) e o índice de placa (IP) foram monitorados, além da quantificação da carga bacteriana total e das espécies bacterianas do complexo vermelho (Porphyromonas gingivalis, Tannerella forsythia e Treponema denticola), em amostras subgengivais, a partir da reação em cadeia da polimerase em tempo real. O volume de fluido crevicular gengival (FCG) também foi monitorado ao longo do tempo. Os resultados primários foram melhorias de PS e NIC. Os dados foram analisados estatisticamente por Análise de variância (ANOVA), comparações múltiplas de diferença menor (LSD), Kruskal-Wallis, Friedman e teste t de Student emparelhado (p<0,05). DTB e RQ forneceram melhorias em PS, NIC, IG, IP e FCG semelhantes. Após o tratamento, o grupo DTB apresentou valores médios mais baixos da carga bacteriana total e de espécies bacterianas do complexo vermelho em comparação com o grupo RQ. DTB e RQ associado a azitromicina sistêmica mostraram ser similarmente uma abordagem terapêutica de curto prazo, eficaz e confiável para o tratamento de periodontite generalizada estágio III e IV. No entanto, DTB demonstrou superioridade sobre os efeitos antibacterianos aos 6 meses em comparação com RQ.

Objective: To analyze osteopontin mRNA expression levels in subjects with periodontitis prior to (baseline) and 7, 14, and 28 days following scaling and root planing (SRP). Material and Methods: Gingival crevicular fluid was collected as clinical samples from four subjects with periodontitis (pocket depth, 4-5 mm) aged 35-54 years old as well as from three healthy subjects (controls). The osteopontin mRNA expression levels were measured by quantitative real-time polymerase chain reaction. Spearman's rank correlation between osteopontin levels in gingival crevicular fluid and the modified gingival index (MGI) was also performed. Results: The Wilcoxon signed-rank test showed no significant difference in osteopontin mRNA expression levels between baseline and 28 days following SRP (p=0.068). The Friedman test showed no significant difference in osteopontin mRNA expression levels between baseline and following SRP (7, 14, or 28 days) (p>0.05). Spearman's rank correlation showed no significant correlation between osteopontin mRNA expression levels and MGI (r=0.087; p=0.749). Conclusion: Following SRP of periodontal tissue, there was a decreasing trend in osteopontin mRNA expression; however, this finding was not statistically significant. Nevertheless, osteopontin can be used as a biomarker to monitor the healing process; however, further studies are required to clarify our results.

Abstract Objective: This study aims to evaluate the clinical and biochemical (oxidative stress and pro-inflammatory mediators) effects of the gaseous ozone use accompanied by scaling and root planning (SRP) in periodontal treatment. Material and Methods: The study population consisted of 40 patients with chronic periodontitis (CP) randomly sorted into two groups of 20. The experimental group received SRP plus 3 watts gaseous ozone in two separate applications five days apart, whereas the control group received SRP plus placebo. Clinical periodontal parameters were assayed and saliva samples were taken before the initial and one month after the second treatment. Periodontal examination assessed plaque index (PI), gingival index (GI), probing depth, and clinical attachment level (CAL). Total antioxidant status (TAS), total oxidant status (TOS), nitric oxide (NO), 8-hydroxy-2'-deoxyguanosine (8-OHdG), myeloperoxidase (MPO), glutathione (GSH), malondialdehyde (MDA), and transforming growth factor-beta (TGF-β) levels were evaluated from saliva samples. Results: Changes following treatment in PI, GI, probing depth, and CAL scores were similar for both groups (p>0.05). Of note, TGF-β levels were observed to be higher in the treatment group than in controls (p<0.05). Changes in 8-OHdG, TAS, TOS, NO, MPO, GSH and MDA levels, however, were not significantly different between groups (p>0.05). Conclusion: The findings of this study indicate that SRP plus gaseous ozone versus SRP alone does not correlate to a significant improvement in periodontal recovery.

Abstract Serum hepcidin levels may increase in response to infection and inflammation. The present study investigated the effect of nonsurgical periodontal therapy (NSPT) on levels of serum hepcidin, inflammatory markers, and iron markers. An interventional study was conducted on 67 patients (age 30-65 years) without other diseases, except for chronic periodontitis (CP). Patients were allocated to either CP or control groups. The CP group received supragingival and subgingival scaling and root planing procedures, whereas the control group received supragingival scaling. Probing depth (PD), bleeding on probing, clinical attachment level (CAL), visible plaque index (VPI), serum hepcidin and interleukin-6 (IL-6) levels, high-sensitivity C-reactive protein (hs-CRP), hematological markers, and iron markers were measured at baseline and at 90 days after NSPT. The CP group had statistically significant lower mean values for mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) (p ≤ 0.05). The control group had statistically significant reductions in hemoglobin, hematocrit, MCV, and MCH (p ≤ 0.05). Serum hepcidin, IL-6, and erythrocyte sedimentation rate (ESR) levels were significantly decreased in both groups after NSPT. Periodontal markers were more markedly reduced in the CP group compared with the control group (p ≤ 0.05). These findings suggest that NSPT may reduce the serum levels of IL-6, hepcidin, and periodontal parameters.

Abstract Introduction Root-scaling procedures on the root surface show to increase root surface roughness during instrumentation. The use of a prophylactic paste reduces the roughness. Objetive This study evaluated the influence of prophylaxis paste on the surface roughness of root dentin after hand instruments (HI), ultrasonic scalers (US) and rotational instruments (RI) were applied to root surfaces. Material and method Fifty bovine roots were prepared and randomly divided into 10 groups (n=5) in which instrumentation with HI, US, or RI was carried out with or without prophylaxis using either conventional or 3% hydroxyapatite paste; additionally, a control group without treatment was included. The Ra and Rz roughness values were measured using a perfilometer. The morphological aspects of the root surfaces were analysed qualitatively by scanning electron microscopy (SEM). Data were analysed using two-way ANOVA followed by Tukey's test (α = 0.05). Result The scaling method and the prophylaxis procedure significantly influenced (p < 0.05) root surface roughness. Treatment with US and prophylaxis with 3% hydroxyapatite paste resulted in lower values ââof Ra (0.14 µm ± 0.02 µm) and Rz (0.89 µm ± 0.18 µm) compared to the other groups. SEM analysis showed smoother and more homogeneous surfaces in the groups with prophylaxis compared to the groups without prophylaxis. There were no substantial differences between the results of applying different pastes. Conclusion The prophylaxis procedure performed with the experimental paste containing 3% hydroxyapatite reduced the roughness of root surfaces treated with HI, US and RI at the same level as the conventional prophylactic paste.
Resumo Introdução Procedimentos de raspagem na superfície radicular aumentam a rugosidade superficial durante a instrumentação. O uso de pasta profilática pode reduzir a rugosidade. Objetivo Este estudo avaliou a influência da profilaxia com pasta na rugosidade superficial da dentina radicular após instrumentação manual (IH), ultrassom (US) e instrumentos rotatórios (IR) aplicados em superfícies radiculares. Material e método Cinquenta raízes bovinas foram preparadas e divididas aleatoriamente em 10 grupos (n = 5) nos quais a instrumentação com HI, US ou RI foi realizada com ou sem profilaxia usando pasta convencional ou hidroxiapatita a 3%; adicionalmente, um grupo controle sem tratamento foi incluído. As rugosidades de Ra e Rz foram medidas por um perfilômetro. Os aspectos morfológicos das superfícies radiculares foram analisados ââqualitativamente por microscopia eletrônica de varredura (MEV). Os dados foram analisados ââpor meio de ANOVA de dois fatores, seguido pelo teste de Tukey (α = 0,05). Resultado O método de raspagem e o procedimento de profilaxia influenciaram significativamente (p <0,05) a rugosidade da superfície radicular. O tratamento com US e a profilaxia com pasta de hidroxiapatita ao 3% resultaram em menores valores de Ra (0,14 µm ± 0,02 µm) e Rz (0,89 µm ± 0,18 µm) em relação aos demais grupos. A análise por MEV mostrou superfícies mais lisas e mais homogêneas nos grupos com profilaxia em comparação aos grupos sem profilaxia. Não houve diferenças substanciais entre os resultados da aplicação das diferentes pastas. Conclusão O procedimento de profilaxia realizado com a pasta experimental contendo 3% de hidroxiapatita reduziu a rugosidade das superfícies radiculares tratadas com HI, US e RI no mesmo nível da pasta profilática convencional.

Abstract In the search for the ideal treatment of periodontal disease various non-surgical techniques should be considered. The objective of this study was to evaluate the efficacy of full-mouth scaling (FMS) by clinical and microbiological parameters. 670 individuals were evaluated with 230 subjects meeting the selection criteria and were divided into two groups; 115 subjects treated with FMS and 115 treated with weekly sessions of scaling and root planning (SRP). The patient population had a mean age of 51.67 years, with moderate chronic periodontitis. Subjects were evaluated prior to treatment (T1) and 90 days after execution of therapy (T2), with regards to: probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), and microbial detection for the presence of Porphyromonas gingivalis (P.g.) and Prevotella intermedia (P.i.) by culture method and confirmed by biochemical tests. Subjects treated in the FMS group also rinsed with 0.12% chlorhexidine mouthwash for seven days following treatment. The results were analyzed using statistical Student's t-test and chi-square test. No statistically significant differences were observed for PD and CAL between T1 and T2 in both groups. For GI and PI significant difference was observed between the groups. For the evaluated microbial parameters was observed reduction of P.g. and P.i., but only for P.g. with a significant reduction in both groups. The full mouth scaling technique with the methodology used in this study provided improved clinical conditions and reduction of P.g. in subjects with moderate periodontitis, optimizing the time spent in the therapeutic execution.
Resumo Na busca do tratamento ideal da doença periodontal varias são técnicas não-cirúrgicas que podem ser consideradas. O objetivo deste estudo foi avaliar a eficácia da técnica de desinfecção total de boca (FMD, na sigla em Inglês) por parâmetros clínicos e microbiológicos. Foram avaliados 670 indivíduos com 230 indivíduos atendendo aos critérios de seleção e divididos em dois grupos; 115 indivíduos tratados com FMD e 115 tratados com sessões semanais de raspagem e alisamento corono radicular (SRP, na sigla em Inglês). A população avaliada tinha idade média de 51,67 anos, com periodontite crônica moderada. Os sujeitos foram avaliados antes do tratamento (T1) e 90 dias após a execução da terapia (T2), quanto à profundidade de sondagem (PS), nível de inserção clínica (NIC), índice de placa (IP), índice gengival (IG) e detecção microbiana da presença de Porphyromonas gingivalis (P.g.) e Prevotella intermedia (P.i.) por método de cultura e confirmada por testes bioquímicos. Os indivíduos tratados no grupo FMD também realizaram bochechos com clorexidina 0,12% durante sete dias após o tratamento. Os resultados foram analisados utilizando o teste estatístico t de Student e o teste de qui-quadrado. Não foram observadas diferenças estatisticamente significativas para PS e NIC entre T1 e T2 em ambos os grupos. Para IG e IP observou-se diferença significativa entre os grupos. Para os parâmetros microbianos avaliados foi observada redução de P.g. e P.i., mas apenas para P.g. com uma redução significativa em ambos os grupos. A técnica FMD com a metodologia utilizada neste estudo proporcionou condições clínicas melhoradas e redução da P.g. Em indivíduos com periodontite moderada, otimizando o tempo gasto na execução terapêutica.
