Mechanical debridement combined with amoxicillin and metronidazole compared with mechanical debridement alone for the treatment of chronic periodontitis: An overview of systematic reviews.

Periodontal mechanical debridement is the most common therapy for the treatment of periodontitis. However, depending on the severity of the disease, mechanical debridement has been recommended in combination with systemic antibiotics. In this study, we performed an overview of systematic reviews using the Friendly Summaries of Body of Evidence using Epistemonikos (FRISBEE) methodology on the effectiveness and safety of mechanical debridement combined with amoxicillin and metronidazole compared to mechanical debridement alone for the treatment of chronic periodontitis. We conducted a systematic search of the Epistemonikos database, extracted data from 10 systematic reviews and re-analyzed data from 23 primary studies to generate a summary of findings (SoF) table. We used RevMan 5.3 and GRADEpro for data analysis and data presentation. The following outcomes were analyzed: probing depth (mean difference (MD): 0.07 mm); clinical attachment level (MD: 0.04 mm); bleeding on probing (MD: 5.06%); and suppuration (MD: 0.31%). There was no evidence of a clinically relevant benefit of periodontal mechanical debridement therapy combined with amoxicillin and metronidazole compared to periodontal mechanical debridement therapy alone for the treatment of chronic periodontitis in the studied periodontal outcomes.

The efficacy of combining adjuvants with non-surgical periodontal therapy in individuals with type 2 diabetes: A Bayesian network meta-analysis.

AIM: This Bayesian network meta-analysis of randomized controlled trials assessed the effect of adjuvant periodontal treatment in both periodontal and HbA1c outcomes in adult individuals with type 2 diabetes (T2DM). MATERIALS AND METHODS: A systematic search was done up to February 2023 comparing sub-gingival debridement (SD) in combination with local or systemic adjuvant treatment with SD alone for individuals with T2DM. The primary outcomes were changes in absolute HbA1c levels and full-mouth probing depth reported at 3- to 6-month post-treatment. RESULTS: Seventy-two eligible publications evaluating 27 adjuvant treatments were retrieved. The combination of SD and systemic antibiotic metronidazole or SD and antioxidant alpha lipoic acid provided, respectively, 1.4% (95% credible interval [CrI] 0.48; 2.20) and 2.4% (95% CrI 1.50; 3.30) more significant improvement on HbA1c levels, and 0.89 mm (95% CrI 0.23; 1.50) and 0.92 mm (95% CrI 0.02; 0.92) greater periodontal probing depth reductions. Other adjuvant treatments provided added benefit to the periodontal outcomes without discernible effects on HbA1c. CONCLUSIONS: Adjuvant use of metronidazole or alpha lipoic acid was the best adjunct option to provide clinically meaningful HbA1c levels and probing depth reductions. However, no strong recommendation can be drawn due to the scarcity of studies for each adjuvant treatment and the low certainty of the resultant evidence.

Melhora na qualidade de vida de pacientes adultos diabéticos acometidos de doença periodontal após terapia periodontal não-cirúrgica: uma revisão sistemática [ / Improvement in the quality of life of adult diabetic patients with periodontal disease after non-surgical periodontal therapy: a systematic review

Algumas doenças comuns da cavidade bucal, podem influenciar o bem-estar geral dos indivíduos. Dentre elas podemos destacar a doença periodontal, que interfere na qualidade de vida (QV) das pessoas em diversos aspectos além do físico, como na função mastigatória, na aparência e até nas relações interpessoais. Esta revisão sistemática teve como objetivo avaliar se o tratamento periodontal não cirúrgico comparado a ausência de tratamento melhora a QV de pacientes diabéticos. Para isso, foi realizada uma revisão de estudos clínicos randomizados e estudos clínicos controlados de acordo com os parâmetros internacionais de transparência em Revisões Sistemáticas e Metanálises PRISMA Statement. A revisão foi cadastrada na Base PROSPERO e foi traçada uma estratégia de busca sobre o assunto nas bases de dados: MEDLINE via PubMed, Scopus, Web of Science, Registro Central de Ensaios Controlados da Cochrane e EMBASE. Seis estudos preencheram todos os critérios de elegibilidade e foram selecionados para revisão sistemática (4 estudos clínicos randomizados e 2 estudos controlados). Cinco estudos demonstraram melhora na QV de pacientes adultos diabéticos após tratamento periodontal e apenas 1 não observou mudanças estatisticamente significantes em nenhum dos domínios de QV avaliados pelo questionário utilizado. Os resultados dessa revisão sistemática sugerem que a tratamento periodontal não cirúrgico leva a uma melhora tanto na QV geral quanto na qualidade de vida relacionada à saúde bucal (QVRSB) de pacientes adultos diabéticos acometidos de doença periodontal (AU)

Some common diseases of the oral cavity can influence the general well-being of individuals. Among them, we can highlight periodontal disease, which interferes with people's quality of life (QoL) in several aspects beyond the physical, such as masticatory function, appearance and even interpersonal relationships. This systematic review aimed to assess whether non-surgical periodontal treatment compared to no treatment improves the QoL of diabetic patients. For this, a review of randomized clinical trials and controlled clinical trials was carried out according to international parameters of transparency in Systematic Reviews and Meta-analyses PRISMA Statement. The review was registered in the PROSPERO database and a search strategy was drawn up on the subject in the databases: MEDLINE via PubMed, Scopus, Web of Science, Cochrane Central Register of Controlled Trials and EMBASE. Six studies met all eligibility criteria and were selected for systematic review (4 randomized controlled trials and 2 controlled trials). Five studies showed improvement in the QoL of adult diabetic patients after periodontal treatment and only 1 did not observe statistically significant changes in any of the QoL domains assessed by the questionnaire used. The results of this systematic review suggest that non-surgical periodontal treatment leads to an improvement in both general QoL and QHRSB of adult diabetic patients with periodontal disease. (AU)

Administração de Lactobacillus para casei 28.4 como terapia adjuvante no tratamento da periodontite: desenvolvimento in vitro de formulação probiótica usando gellan gum e ensaio clínico randomizado placebo controlado / Administration of Lactobacillus paracasei 28.4 as adjuvant therapy in the treatment of periodontitis: in vitro development of the probiotic formulation using gellan gum and placebo-controlled randomized clinical trial

A periodontite é uma doença inflamatória do periodonto associada ao acúmulo de biofilme dental, com consequente disbiose da microbiota oral e alteração da resposta imuno-inflamatória. O controle da periodontite realizado por meio do tratamento periodontal não-cirúrgico altera o ambiente subgengival e pode ser associado a terapias adjuntas. O uso de probióticos como terapia adjuvante a esse tratamento parece favorecer a modificação do biofilme bacteriano e resposta imuno-inflamatória. Entretanto, os probióticos empregados até o momento não são próprios da cavidade oral e, por isso, a busca por cepas originadas da microbiota oral tem ganhado espaço na tentativa de favorecer a aderência e colonização permanente dessas bactérias. Recentemente, a cepa de Lactobacillus paracasei 28.4 foi isolada da cavidade oral, exibindo atividades antimicrobianas promissoras sobre o controle de patógenos orais. O presente estudo teve como objetivos o desenvolvimento de uma formulação probiótica de L. paracasei 28.4 incorporado em gellan gum para uso humano, bem como a avaliação dos efeitos clínicos da administração desta formulação como adjuvante no tratamento periodontal. Para tal, o trabalho foi dividido em 2 etapas, contemplando uma etapa laboratorial (parte A), para desenvolvimento da formulação probiótica; e um ensaio clínico randomizado (parte B, n=40), envolvendo um protocolo de tratamento periodontal não cirúrgico associado à terapia adjunta probiótica ou placebo. Os resultados da parte A permitiram encontrar a melhor forma de apresentação e armazenamento da formulação de gellan gum. Na parte B, aos 3 e 6 meses de acompanhamento, os dois grupos apresentaram melhoras significativas dos parâmetros periodontais (índice de sangramento, índice gengival, profundidade de sondagem e ganho de nível de inserção) em relação ao baseline, sem diferença estatística na comparação intergrupo. Como conclusão, uma formulação probiótica segura e possível de ser aplicada na prática clínica foi obtida; no entanto, sua administração não promoveu efeitos clínicos adicionais ao tratamento de pacientes com periodontite generalizada estágios III/IV e graus B/C (AU)

Periodontitis is an inflammatory disease of the periodontium associated with the accumulation of dental biofilm, with consequent dysbiosis of the oral microbiota and alteration of the immune-inflammatory responseThe control of periodontitis carried out through non-surgical periodontal treatment alters the subgingival environment and can be associated with adjunctive therapies.The use of probiotics as an adjuvant therapy in the periodontal treatment seems to favor the modification of the bacterial biofilm and modulation of the immuneinflammatory response. However, the probiotics used so far are not specific to the oral cavity and, therefore, the search for strains originating from the oral microbiota has gained space to favor the adherence and permanent colonization of these bacteria. Recently, strain of Lactobacillus paracasei 28.4 was isolated from the oral cavity itself, showing promising antimicrobial activities in the control of oral pathogens. The present study aimed to develop and characterize a probiotic formulation of L. paracasei 28.4 incorporated into gellan gum for human use, as well as to evaluate the clinical effects of administering this formulation as an adjuvant in the treatment of periodontitis. To this end, the study was divided into 2 stages, comprising a laboratory stage (part A), for the development of the probiotic, and a randomized clinical trial (part B, n=40) contemplating a non-surgical periodontal treatment protocol associated with adjunctive probiotic therapy or placebo. The results from part A made it possible to find the best way to present and store the gellan gum formulation. In part B, at 3 and 6 months of follow-up, both groups showed significant improvements in periodontal parameters (bleeding index, gingival index, probing depth and attachment level gain) in relation to baseline, with no statistical difference in the intergroup comparison. In conclusion, a safe probiotic formulation that can be applied in clinical practice was obtained; however, its administration did not promote additional clinical effects in the treatment of patients with stage III/IV and grades B/C generalized periodontitis (AU)

Effect of periodontal debridement plus systemic azithromycin in subjects with stage III periodontitis: a randomized controlled clinical trial / Efecto del desbridamiento periodontal más azitromicina sistémica en sujetos con periodontitis estadio III: un ensayo clínico controlado aleatorio

Aim: To evaluate the effect of the systemic administration of azi-thromycin (AZM) as an adjunct to non-surgical periodontal therapy (NSPT) on the clinical and microbiological variables of patients with periodontitis. Material and Methods: Eighteen volunteers received NSPT combined with placebo or AZM (500 mg/day) for 3 days (n=9/group). They were monitored clinically for probing pocket depth (PPD), clinical attachment level (CAL), O'Leary index (OI), bleeding on probing (BoP) at baseline and during the first, third and sixth month and microbiologically, at baseline and at 3 and 6 months after therapy, by conventional polymerase chain reaction tests. Results: Fourteen patients completed the study (n=7/group). Differences statistically significant were observed among both groups. The experimental group presented: A PPD mean (p=0.04) significantly lower and PPD reduction (p=0.02), at 6-months post NSPT. Regarding changes (∆), at the third month post NSPT, there was a significant increase in the number of shallow sites (p<0.001) and a decrease in the intermediate sites (p<0.001). In addition, a significant decrease in the mean number of deep sites (p=0.04) was detected at 6 months post treatment. There was also a significant decrease in periodontal index BoP at 1 (p=0.01), 3 (p<0.001) and 6 (p=0.01) months and OI at 3- and 6-months (p<0.001), post treatment. Regarding the presence of periodontal pathogens, no significant differences were observed, intra and inter groups. Conclusion: AZM as an adjuvant to NSPT provides additional beneficial effects for PPD and BoP compared to NSPT alone.

Objetivo: Evaluar el efecto de la administración sistémica de azitromicina (AZM) como coadyuvante de la terapia periodontal no quirúrgica (TPNQ) en las variables clínicas y microbiológicas de pacientes con periodontitis. Material y Métodos: Dieciocho voluntarios recibieron TPNQ combinado con placebo o AZM (500 mg/día) durante 3 días (n=9/grupo). Fueron monitoreados clínicamente para determinar Profundidad de Sondaje del Saco (PSS), Nivel de Inserción Clínica (NIC), Índice de O'Leary (IO), Sangrado al sondaje (SS) al inicio y durante el primer, tercer y sexto mes y microbiológicamente, al inicio y a los 3 y 6 meses después de la terapia, mediante la reacción en cadena de la polimerasa convencional. Resultados: Catorce pacientes completaron el estudio (n=7/grupo). Se observaron diferencias estadísticamente significativas entre ambos grupos. El grupo experimental presentó una media de PSS significativamente menor (p=0,04) y una reducción de PSS (p=0,02), a los 6 meses post TPNQ. En cuanto al delta (∆) pre y post tratamiento, al tercer mes post TPNQ, hubo un aumento significativo en el número de sitios poco profundos (p<0.001) y una disminución en los sitios intermedios (p<0.001). Además, se detectó una disminución significativa en la media de los sitios profundos (p=0.04) a los 6 meses post tratamiento. También hubo una disminución significativa en el índice SS al primer (p=0.01), tercer (p<0. 0 01) y sexto mes (p=0.01) post TPNQ y del IO al tercer y sexto mes (p<0.001), post tratamiento. En cuanto a la presencia de patógenos periodontales, no se observaron diferencias significativas tanto intra como ínter grupos. Conclusión: AZM como adyuvante a TPNQ proporciona efectos benéficos adicionales en la PSS y SS en comparación a TPNQ solo.

Open flap debridement compared to repeated applications of photodynamic therapy in the treatment of residual pockets: A randomized clinical trial.

BACKGROUND: The aim of the present study was to compare repeated applications of antimicrobial photodynamic therapy (aPDT) to open flap debridement (OFD) in the treatment of residual periodontal pockets in non-furcation sites. METHODS: Forty-six subjects with a diagnosis of Stage III or IV Grade C periodontitis, that had been previously treated, participated in the study.  Residual pockets were divided between two groups: (1) aPDT group: received ultrasonic periodontal debridement followed by immediate application of aPDT, and repeated on1st, 2nd, 7th, and 14th days; and (2) OFD group: treated by modified papilla preservation technique, where granulation tissue and visible calculus were removed with hand curettes and an ultrasonic device. Clinical, immunological, and microbiological parameters were evaluated before and after treatment. RESULTS: Both treatments were effective reducing clinical parameters of disease. OFD resulted in a greater mean probing pocket depths (PPD) reduction in deep pockets (p = 0.001). However, aPDT resulted in a lower occurrence of gingival recession (GR), dentin hypersensitivity (DH) and analgesic intake. Reduction in Porphyromonas gingivalis was observed in both groups. Only the OFD group had a significant reduction in Aggregatibacter actinomycetemcomitans. aPDT group had greater increase in interleukin 10 (IL-10) levels and a greater reduction of interleukin 1 beta (IL-1ß) at 14 days when compared to the OFD group (p < 0.05). CONCLUSION: OFD was superior in reducing PPD in deep pockets compared to the aPDT. However, OFD resulted in greater GR.  Both treatments lowered P. gingivalis levels but only OFD reduced levels of A. actinomycemtemcomitans.

Non-surgical periodontal debridement affects subgingival bacterial diversity in patients with HIV-1 and periodontitis.

BACKGROUND: Following human immunodeficiency virus-1 (HIV-1) infection and antiretroviral therapy, the development of periodontal disease was shown to be favored. However, the influence of HIV-1 infection on the periodontal microbiota after non-surgical periodontal debridement (NSPD) needs a broad comprehension. This work aimed to compare the subgingival microbiological content of patients infected with HIV-1 and controls (non-infected) with periodontitis undergoing NSPD. METHODS: The bacterial profile of subgingival biofilm samples of patients with HIV-1 (n = 18) and controls (n = 14) with periodontitis was assessed using 16S rRNA gene sequencing. The samples were collected at baseline, 30, and 90 days after NSPD. The taxonomic analysis of gingival microbiota was performed using a ribosomal RNA database. The microbiota content was evaluated in the light of CD4 cell count and viral load. RESULTS: Both HIV and control groups showed similar stages and grades of periodontitis. At baseline, the HIV group showed higher alpha diversity for both healthy and periodontal sites. Streptococcus, Fusobacterium, Veillonella and Prevotella were the predominant bacterial genera. A low abundance of periodontopathogenic bacteria was observed, and the NSPD induced shifts in the subgingival biofilm of patients with HIV-1, leading to a microbiota similar to that of controls. CONCLUSIONS: Different subgingival microbiota profiles were identified-a less diverse microbiota was found in patients infected with HIV-1, in contrast to a more diverse microbiota in controls. NSPD caused changes in the microbiota of both groups, with a greater impact on the HIV group, leading to a decrease in alpha diversity, and produced a positive impact on the serological immune markers in patients infected with HIV-1. Control of periodontitis should be included as part of an oral primary care, providing the oral health benefits and better control of HIV-1 infection.

Comparação entre as técnicas de raspagem e alisamento radicular e desbridamento ultrassônico no protocolo de desinfecção de boca toda: relato de caso / Comparison between scaling and root planing and ultrasonic debridement techniques in the full mouth disinfection protocol: case report

O tratamento periodontal consiste na remoção do biofilme patogênico, através da raspagem e alisamento radicular. O desbridamento ultrassônico de boca toda promove uma instrumentação mais conservadora, porém eficiente da superfície radicular, em sessão única. Evitando a translocação bacteriana de uma região tratada para outra que já foi. O objetivo do presente trabalho foi realizar uma comparação entre a eficácia da raspagem manual e a ultrassônica dentro do protocolo da FMD, através de um relato de caso clínico. Houve uma melhora nos parâmetros clínicos periodontais em todos os quadrantes, porém resultados superiores foram observados com o desbridamento com ultrassom e irrigação com clorexidina. A instrumentação com ultrassom associada a clorexidina no tratamento da periodontite estágio III grau C generalizada, reduz com eficácia o tempo de tratamento, otimizando o tempo do paciente e profissional(AU)

Periodontal treatment consists of removing the pathogenic biofilm, by scaling and root planing. Ultrasonic debridement of the entire mouth promotes more conservative, yet efficient instrumentation of the root surface, in a single session. Avoiding bacterial translocation from one treated region to another that has already been. The objective of the present study was to make a comparison between the effectiveness of manual and ultrasonic scraping within the FMD protocol, through a clinical case report. There was an improvement in periodontal clinical parameters in all quadrants, but superior results were observed with debridement with ultrasound and irrigation with chlorhexidine. Instrumentation with ultrasound associated with chlorhexidine in the treatment of generalized stage III grade C periodontitis, effectively reduces treatment time, optimizing patient and professional time(AU)

Surgical and non-surgical debridement for the treatment of peri-implantitis: a two-center 12-month randomized trial.

OBJECTIVES: To compare surgical (ST) and non-surgical (NST) debridement for the treatment of peri-implantitis in a two-center randomized trial. MATERIALS AND METHODS: Forty-five individuals with 63 implants with probing depth (PPD) ≥5mm, bleeding on probing (BOP), and radiographic bone loss ≥2mm were included. In the NST (30 implants), submucosal debridement was performed. In the ST (33 implants), a mucoperiosteal flap was raised and surfaces were decontaminated only by debridement as performed in NST. Clinical parameters and radiographs were compared at baseline and after 12 months. Means and standard errors were reported. RESULTS: PPD considering all implant sites reduced significantly in NST from 4.14±0.25 to 3.25±0.18mm. In ST, PPD also significantly changed (3.74±0.22 to 3.00±0.29mm). No significant differences were observed between the two groups. For deep sites (≥7mm), PPD was 7.82±0.20mm at baseline and reduced to 5.10±0.30mm in NST, while in ST group, it was 7.11±0.11mm and changed to 5.22±0.91mm (between-groups p value=0.51). BOP significantly reduced from ~60 to 35% of all sites in both groups, without significant differences between them. When sites with radiographic bone level ≥3mm at baseline were analyzed, there was a significant difference between groups in bone gain after 12 months in favor of ST (ST=0.78±0.30mm compared to NST=0.25mm±0.13; p=0.03). CONCLUSIONS: Surgical and non-surgical debridement for the treatment of peri-implantitis present similar clinical outcomes. Bone levels were better improved in ST than NST for sites with higher initial bone loss. CLINICAL RELEVANCE: The treatment of peri-implantitis is still a challenge in clinical practice, since less than half of affected implants achieve health after surgical or non-surgical debridement. Considering the lack of clinically relevant differences between these two treatments, non-surgical debridement should be considered the first therapeutic choice for peri-implantitis, mainly mild to moderate cases.

Efeito da terapia probiótica (Lactobacillus reuteri) coadjuvante no tratamento da periodontite associada ao Diabetes Mellitus: estudo clínico, controlado e randomizado / Effect of adjuvant probiotic therapy (Lactobacillus reuteri) in the treatment of periodontitis associated with Diabetes Mellitus: clinical, controlled and randomized study

A associação de probióticos ao debridamento mecânico pode ser uma proposta de tratamento das doenças periodontais, em especial para pacientes portadores de Diabetes Mellitus tipo 2 (DM2). Avaliou-se os efeitos da administração do probiótico Lactobacillus reuteri como terapia coadjuvante no tratamento da Periodontite (P) associada ao DM2. Um total de 40 participantes diabéticos e diagnosticados com P foram randomizados em Grupo RAR+Placebo (n=20): receberam debridamento mecânico associado ao probiótico e Grupo RAR+Probi (n=20): tratados com debridamento mecânico associado a um placebo. Foram realizadas avaliações de profundidade de sondagem (P.S.), recessão gengival (RG), nível de inserção clínica (NIC), índice de placa (IP), índice de sangramento gengival (IG) e índice PISA no baseline, 30, 90 e 180 dias. Foi realizada dosagem da concentração de citocinas (INF-γ, IL-10, IL-12, IL-13, IL1ß, IL-4, IL-6, IL-8, TNF-α) do fluido crevicular gengival (FCG), no baseline e 180 dias após o tratamento. Informações sobre efeitos adversos do uso de medicamentos e sobre qualidade de vida foram coletadas. Os dados foram obtidos em média e desvio padrão, e analisados pelos testes Fridman/Tukey e MannWhiteny. Considerado a metodologia do presente estudo, os resultados obtidos apontam que o debridamento periodontal promoveu melhora significativa (p<0.05) nos parâmetros clínicos periodontais em ambos os grupos, mas o uso do probiótico não foi eficiente para resultados adicionais quando comparado com o placebo. A terapia periodontal interferiu nos níveis de citocinas do FCG, porém não se pode afirmar que o uso de probiótico apresenta o mesmo efeito(AU)

The association of probiotics with mechanical debridement may be a proposal for the treatment of periodontal diseases, especially for patients with type 2 Diabetes Mellitus (DM2). The effects of the administration of the probiotic Lactobacillus reuteri as an adjunctive therapy in the treatment of Periodontitis (P) associated with DM2 were evaluated. A total of 40 diabetic participants and diagnosed with P were randomized into Group RAR + Placebo (n = 20): received mechanical debridement associated with the probiotic and Group RAR + Probi (n = 20): treated with mechanical debridement associated with a placebo. Probing depth (P.S.), gingival recession (RG), clinical insertion level (NIC), plaque index (IP), gingival bleeding index (IG) and PISA index were performed at baseline, 30, 90 and 180 days. Measurement of the concentration of cytokines (INF-γ, IL-10, IL-12, IL-13, IL-1ß, IL-4, IL-6, IL-8, TNF-α) of the gingival crevicular fluid (FCG), at baseline and 180 days after treatment. Information on adverse effects of medication use and on quality of life was collected. The data were obtained in mean and standard deviation, and analyzed by the Fridman / Tukey and MannWhiteny tests. Considering the methodology of the present study, the results obtained point out that periodontal debridement promoted a significant improvement (p <0.05) in periodontal clinical parameters in both groups, but the use of probiotic was not efficient for additional results when compared with placebo. Periodontal therapy interfered with FCG cytokine levels, but it cannot be said that the use of probiotics has the same effect. Cytokines(AU)

Efeito da terapia fotodinâmica antimicrobiana como adjuvante no tratamento não cirúrgico da periodontite estádio III ou IV grau C / Effect of antimicrobial photodynamic therapy as an adjuvant in the non-surgical treatment of stage III or IV grade C periodontitis

A Periodontite estádio III e IV grau C em pacientes jovens tem um caráter mais destrutivo dos tecidos periodontais de suporte e tem impacto em perdas dentárias, função mastigatória e pior resposta ao tratamento. E a Terapia Fotodinâmica Antimicrobiana (TFD) tem surgido como uma alternativa promissora adjuvante à Terapia Periodontal não Cirúrgica (TPNC) desta doença. OBJETIVO: avaliar os efeitos da TFD como adjuvante no TPNC da Periodontite estádio III ou IV grau C, através dos parâmetros clínicos periodontais (Índice de Placa Visível (IPV), Índice de Sangramento Gengival (ISG), Sangramento à Sondagem (SS), Profundidade de Sondagem (PS), Recessão Gengival (RG), Nível de Inserção Clínica (NIC) e Mobilidade Dentária (MOB)) bem como avaliar seu impacto na qualidade de vida dos pacientes por meio do Oral healthrelated quality of life (OHRQoL). METODOLOGIA: Vinte e um indivíduos participaram desse ensaio clínico controlado randomizado, duplo cego, em um desenho de boca dividida por quadrantes. Todos os pacientes foram tratados com orientação de higiene bucal, raspagem e alisamento radicular por meio do Full Mouth Disinfection (FMD) e antibioticoterapia sistêmica. Os quatro quadrantes foram randomizados de acordo com os seguintes grupos: grupo 1 (FMD + AB), grupo 2 (FMD + AB + TFD em sessão única), grupo 3 (FMD + AB + TFD em quatro sessões) e grupo 4 (FMD + AB + laserterapia com luz infravermelha em quatro sessões). As avaliações foram feitas no baseline e com média de 6 meses após o tratamento. RESULTADOS: Obteve-se uma melhora dos parâmetros clínicos com redução significativa da PS, NIC e SS para todos grupos e da MOB para os grupos FMD + AB, FMD + AB + TFD sessão única e FMD + AB + TFD em 4 sessões após o tratamento, apresentou redução expressivamente maior do NIC no grupo FMD + AB + TFD 4 sessões (ΔMédia = 3,04 mm) em relação ao grupo FMD + AB (Δmédia =2,18 mm), ou seja, com diferença de 0,86 mm. A estratificação das PS no baseline em PS = 5mm e PS ≥ 6mm mostrou que para PS ≥ 6mm, o grupo FMD + AB + TFD em 4 sessões apresentou maior redução da PS (p = 0,005) e NIC (p = 0,001) em relação ao grupo FMD + AB. Em relação à QV, houve aumento significativo dos valores OHRQoL (p = 0,001) e dos domínios físico (p < 0,001), social (p = 0,027) e psicológico (p = 0,005) após o tratamento. CONCLUSÃO: A terapia periodontal do FMD associada a antibioticoterapia, com acréscimo ou não da TFD apresenta resultados significativos na melhora dos parâmetros clínicos periodontais e, em bolsas mais profundas, a TFD em 4 sessões apresentou resultados superiores. Ademais, a Periodontite estádio III ou IV grau C reflete negativamente na percepção da QV, porém, a TPNC apresentou impacto positivo sobre a mesma (AU).

Stage III ­ IV grade C periodontitis in young patients has a more destructive character of periodontal support tissues and has impact on loss of teeth, masticatory function and worse response to treatment. The Antimicrobial Photodynamic Therapy (PDT) has become as a promising alternative, adjuvant to Non-Surgical Periodontal Therapy (NSPT) of this disease. OBJECTIVE: To evaluate the effect of adjunctive PDT on the non-surgical treatment of stage III ­ IV, grade C Periodontitis, through the analysis of periodontal clinical parameters (Visible Plaque Index (VPI), Gingival Bleeding Index (GBI), Bleeding on Probing (BP), Pocket Probing Depth (PPD), Gingival Recession (GR), Clinical Attachment Level (CAL) and Tooth Mobility (Mob)) as well as to assess their impact on quality of life (QoL) of the patients through Oral health-related quality of life (OHRQoL) questionnaire. METHODOLOGY: Twenty-one subjects particpated in this controlled randomized, double-blind trial, in a split-mouth design divided into quadrants. All the patients were treated with oral hygiene guidance, scaling and root planing through Full Mouth Disinfection (FMD) and systemic anbiotics. The four quadrants were randomly assigned to the following treatment groups: group (FMD + AB), group 2 (FMD + AB + PDT in a single session), group 3 (FMD + AB + PDT in four sessions), and group 4 (FMD + AB + laser therapy with infrared light in four sessions). Assessments were made at baseline and an average of 6 months after treatment. RESULTS: There was an improvement in clinical parameters with significant reduction of PPD, CAL and BoP for all therapies as well as Mob for FMD + AB, FMD + AB + PDT in a sihgle session and FMD + AB + PDT in 4 sessions groups, however there was a significantly greater reduction in CIN in the FMD + AB + PDT group 4 sessions (ΔAverage = 3.04 mm) in relation to the FMD + AB group (ΔAverage = 2.18 mm), that is, with a difference of 0.86 mm. Stratification of the baseline pockets in PPD = 5mm and PPD ≥ 6mm showed that, for PPD ≥ 6mm, FMD + PDT in 4 sessions had a greater reduction of PPD (p = 0.005) and CAL (p = 0.001) in relation to FMD group). Regarding QoL analysis, there was a significant increase in the OHRQoL (p = 0.001) and in the physical (p < 0,001), social (p = 0.027) and psychological (p = 0.005) domains after treatment. CONCLUSION: FMD therapy associated with systemic antibiotic therapy, with or without addition of PDT, showed significant improvement of the clinical periodontal parameters and, in deeper pockets, PDT in 4 sessions showed better results. Furthermore, stage III - IV grade C Periodontitis reflected negatively on the QoL perception, however, NSPT had a positive impact on it (AU).

Ozonoterapia como adyuvante en el tratamiento periodontal no quirúrgico y quirúrgico / Ozonoterapia as adjuvant in the non-surgical and surgical periodontal treatment

Introducción: El ozono (O3) presenta múltiples acciones biológicas, entre ellas su efecto antimicrobiano, lo que ha sido beneficioso en odontología, siendo la presentación acuosa la más utilizada (20 µg/ mL), la cual presenta efectos similares a la clorhexidina. Reporte de caso: Paciente masculino de 76 años de edad, diagnosticado con periodontitis crónica moderada localizada, el cual fue tratado mediante ozonoterapia acuosa durante la fase inicial periodontal y la fase quirúrgica en colgajo por debridación. 12 semanas posteriores al acto quirúrgico se obtuvo la eliminación de las bolsas periodontales, encontrándose un surco de 3 y 2 mm y un buen control de placa dentobacteriana. Conclusión: No existen reportes acerca del uso de ozonoterapia acuosa durante un colgajo por debridación. El éxito del tratamiento periodontal consiste en la eliminación del factor causal así como en establecer y mantener un control de placa dentobacteriana adecuado (AU)

Conclusion: There are no reports about the use of aqueous ozone therapy during a debridement flap. The success of the periodontal treatment consists in the elimination of the causal factor, as well as establishing and maintaining an adequate control of plaque (AU)

Tratamiento no quirúrgico del agrandamiento gingival asociado a la pubertad: reporte de caso clínico / Non-surgical treatment of gingival enlargement associated with puberty: a clinical case report

RESUMEN Introducción: los agrandamientos gingivales suelen tratarse a través de terapias quirúrgicas de gingivectomías; su tratamiento no quirúrgico mecánico también es una opción sobre todo en los casos de gingivitis asociada a la pubertad como consecuencia de los cambios hormonales. Objetivo: describir el tratamiento no quirúrgico de una paciente de 12 años con agrandamiento gingival asociado a la pubertad y lesiones gingivales inducidas por biofilm dental. Presentación del caso: el caso presentó un agrandamiento gingival leve localizado que remitió al cabo de un mes a la primera fase de tratamiento, después de tres sesiones de fisioterapias con la remoción de biofilm calcificado se obtuvo una reducción del porcentaje del índice de higiene oral sin requerir intervención quirúrgica. A los cuatro años de seguimiento se observó reducción completa del agrandamiento gingival y bolsas periodontales. Conclusiones: la terapia periodontal mecánica es una alternativa eficaz en la reducción de la inflamación gingival inducida por hormonas durante la pubertad sin la necesidad de requerir intervenciones quirúrgicas para el tratamiento del agrandamiento gingival. Otras alternativas como las gingivectomías son aplicables; sin embargo requieren procedimientos más complejos, costosos y aumento de la morbilidad del paciente; en ese sentido el tratamiento mecánico no quirúrgico se muestra como una opción viable(AU)

ABSTRACT Introduction: Gingival enlargement is usually treated with gingivectomy as an alternative to surgery; however, non-surgical mechanical treatment is another option especially in cases of gingivitis associated with puberty as a result of hormonal changes. Objective: To describe the non-surgical treatment of a 12-year-old patient with gingival enlargement associated with puberty and gingival lesions induced by dental biofilm. Case presentation: The patient presented a localized mild gingival enlargement that relapsed to the first phase of treatment after one month. Three months after physiotherapy sessions with removal of calcified biofilm, a reduction in the percentage of oral hygiene index to "good" was obtained; therefore, surgical treatment was not required. Four years later, there was a complete reduction in gingival enlargement and periodontal pockets. Conclusions: Mechanical periodontal therapy is an effective alternative to reduce gingival inflammation induced by hormones during puberty not requiring surgical intervention to treat gingival enlargement. Other alternatives such as gingivectomies are performed; however, they require more complex, expensive procedures and they can also increase patient morbidity. In that sense, the uniqueness of the non-surgical mechanical treatment is chosen as a feasible option(AU)

Omega-3 PUFA and aspirin as adjuncts to periodontal debridement in patients with periodontitis and type 2 diabetes mellitus: Randomized clinical trial.

BACKGROUND: Supplementation with omega-3 polyunsaturated fatty acids (ω-3 PUFA) and low-dose aspirin (ASA) have been proposed as a host modulation regimen to control chronic inflammatory diseases. The aim of this study was to investigate the clinical and immunological impact of orally administered ω-3 PUFA and ASA as adjuncts to periodontal debridement for the treatment of periodontitis in patients type 2 diabetes. METHODS: Seventy-five patients (n = 25/group) were randomly assigned to receive placebo and periodontal debridement (CG), ω-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) after periodontal debridement (test group [TG]1), or ω-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) before periodontal debridement (TG2). Periodontal parameters and GCF were collected at baseline (t0), 3 months after periodontal debridement and ω-3 PUFA + ASA or placebo for TG1 and CG (t1), after ω-3 PUFA + ASA (before periodontal debridement) for TG2 (t1), and 6 months after periodontal debridement (all groups) (t2). GCF was analyzed for cytokine levels by multiplex ELISA. RESULTS: Ten patients (40%) in TG1 and nine patients (36%) in TG2 achieved the clinical endpoint for treatment (less than or equal to four sites with probing depth ≥ 5 mm), as opposed to four (16%) in CG. There was clinical attachment gain in moderate and deep pockets for TG1. IFN-γ and interleukin (IL)-8 levels decreased over time for both test groups. IL-6 levels were lower for TG1. HbA1c levels reduced for TG1. CONCLUSION: Adjunctive ω-3 and ASA after periodontal debridement provides clinical and immunological benefits to the treatment of periodontitis in patients with type 2 diabetes.

Efeito das terapias antibiótica e probiótica no tratamento adjuvantes da periodontite: estudo clínico controlado randomizado / Effect of antibiotic and probiotic therapies on adjuvant treatment of periodontitis: randomized controlled trial

O objetivo deste projeto foi avaliar a resposta dos parâmetros periodontais clínicos: Índice de Placa (IP), Sangramento à Sondagem (SS), Profundidade de sondagem (PS), Recessão gengival (RG) e Nível de Inserção Clínica (NIC) e PISA, diante da comparação de duas diferentes terapias adjuvantes (antibiótico e probiótico) para o tratamento da periodontite (Grau B Estágios II e III). Para tal, 45 pacientes foram incluídos no estudo divididos aleatoriamente em 3 grupos com n=15: grupo DEB (Debridamento); grupo DEB+ATB (Debridamento + Amoxicilina 500mg + Metronidazol 400mg) e grupo DEB+PROBI (Debridamento+Probiótico Lactobacillus reuteri). As análises dos parâmetros clínicos foram realizadas no Baseline, 30 dias e 90 dias. Para os dados não paramétricos foi realizado o teste de variância KruskalWallis através do software BioEstat 5.3 (Belém, PA, Brazil) e teste de Dunn post hoc para as comparações múltiplas. Para os dados com distribuição normal, foi utilizado o teste Qui-Quadrado e One Way ANOVA, todos com α = 5%. Em relação ao IP o grupo DEB+PROBI apresentou menores valores em relação aos demais grupos em 30 dias (0,43 ± 0,13, p=0,008) e em 90 dias (0,43 ± 0,11, p= 0,001). Para SS na comparação intergrupos o grupo DEB+ATB apresentou menores valores em 90 dias (0,28 ± 0,07, p= 0,03). Para PS e NIC de boca toda na comparação intergrupos não houve diferença estatística entre os valores. Para RG de boca toda o grupo DEB+PROBI apresentou diferença estatística (0,35± 0,15, p=0,006). Os valores de PISA não apresentaram diferenças estatisticamente significantes na comparação intergrupos. Em relação à estratificação das bolsas (moderadas e profundas), a PS para bolsas profundas apresentou na comparação intergrupos menores valores em 90 dias para o grupo DEB+ATB (4,31 ± 0,84, p=0,02) e em relação a quantidade de bolsas residuais, na comparação intergrupos o grupo DEB+ATB apresentou uma menor quantidade de sítios (0,93 ± 1,28, p=0,04) em 30 dias. O grupo DEB+ATB apresentou uma maior quantidade de efeitos adversos quando comparado ao grupo DEB+PROBI, o qual nenhum paciente relatou a ocorrência de efeitos adversos. Podemos concluir que ambas terapias adjuvantes, durante o período de avaliação de 90 dias, apresentaram resultados sem diferenças estatísticamente significantes na redução da profundidade de sondagem, porém, clinicamente, apesar de uma maior incidência de efeitos adversos, o antibiótico mostrou-se mais eficaz na redução de bolsas profundas(AU)

The objective of this project was to evaluate the response of clinical periodontal parameters: Plaque Index (IP), Bleeding on Probing (BoP), Probing Depth (PD), Gingival Recession (GR), Clinical Attachment Level (CAL) and PISA, comparing two different adjuvant therapies (antibiotic and probiotic) for the treatment of periodontitis (Grade B Stages II and III). For this, 45 patients were included in the study, randomly divided into 3 groups with n = 15: DEB group (Debridement); DEB + ATB group (Debridement + Amoxicillin 500mg + Metronidazole 400mg) and DEB + PROBI group (Debridement + Lactobacillus reuteri probiotic). The analyzes of clinical parameters were performed at baseline, 30 days and 90 days. For non-parametric data, the Kruskal-Wallis variation test was performed using the BioEstat 5.3 software (Belém, PA, Brazil) and Dunn post hoc test for multiple comparisons. For data with normal distribution, the Chi-Square and One Way ANOVA tests were used, all with α = 5%. Regarding PI, DEB + PROBI group presents lower values in relation to the other groups in 30 days (0.43 ± 0.13, p = 0.008) and in 90 days (0.43 ± 0.11, p = 0.001). For BoP in the intergroup comparison of the DEB + ATB group, the values are lower in 90 days (0.28 ± 0.07, p = 0.03). For PD and CAL of full mouth parameters the comparative comparison showed that there was no statistical difference between the values. For full mouth GR, DEB + PROBI group shows statistical difference (0.35 ± 0.15, p = 0.006). The PISA values did not show statistically significant differences in the comparison between groups. Regarding the pockets stratification (moderate and deep), a PD for deep pockets shows at the intergroup comparison lower values in 90 days for the DEB + ATB group (4.31 ± 0.84, p = 0.02) and in relation to the number of residual pockets, in the comparison between groups, the group DEB + ATB, presents a smaller number of sites (0.93 ± 1.28, p = 0.04) in 30 days. The DEB + ATB group had a higher number of adverse effects when compared to the DEB + PROBI group in which no patient related to the occurrence of adverse effects. we can conclude that both adjunct therapies during the 3-month evaluation period showed results without statistically significant differences, however clinically, despite having a higher incidence of adverse effects, the antibiotic proved to be more effective in reducing deep pockets(AU)

Influence of Periodontal Disease on cardiovascular markers in Diabetes Mellitus patients.

The objective of the present study was to establish if individuals with Diabetes Mellitus (DM2) and periodontal diseases (gingivitis or periodontitis) presented an increase in the concentration of modified LDL (moLDL) and what is the influence of periodontal treatment on the decrease of moLDL particles with consequent improvement in the parameters of DM2. Twenty-four diabetic patients with periodontitis (Group 1) and twenty-four diabetic patients with gingivitis (Group 2) were followed up for a period of 12 months. Group 1 was treated with periodontal debridement, and Group 2 received supra-gingival scaling and prophylaxis. In both groups, periodontal clinical parameters: probing depth (PD), clinical attachment level (CAL), gingival resection (GR), bleeding on probing index (BOP) and plaque index; inflammatory serum markers (glycemia, A1c, total cholesterol, HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c), triglycerides and hs-CRP) and oxidized LDL (oxLDL) were measured at baseline, t = 6 and t = 12 months after treatment. Solutions of LDL were analyzed using the nonlinear optical Z-Scan and optical absorption techniques. The periodontal clinical parameters showed significant improvement (p < 0.05) in both Group after 12 months. For both groups, total cholesterol, HDL-c, LDL-c, triglycerides and A1c levels did not show significant reductions after periodontal therapy. hs-CRP levels in Group 1 presented a significant reduction after 12 months. The glycemic rate and the oxLDL concentrations did not show significant differences as a function of time. The optical measurements of LDL solutions revealed an improvement of the LDL-c quality in both groups. Periodontal debridement was able to improve periodontal parameters and the quality of LDL-c in diabetic patients but without changes in the oxLDL concentration in both groups. Considering the clinical relevance, the reduction of infectious and inflammatory sites present in the oral cavity through periodontal therapy may help with the control and prevention of hyperglycemia and precursors of cardiovascular diseases.

Evaluation of the local effect of nonsurgical periodontal treatment with and without systemic antibiotic and photodynamic therapy in generalized aggressive periodontitis. A randomized clinical trial.

BACKGROUND: This study's aim was to evaluate the local effect of clarithromycin associated with antimicrobial photodynamic therapy (aPDT) in the treatment of generalized aggressive periodontitis. MATERIALS AND METHODS: The study sample comprised 72 periodontal pockets on single-rooted teeth in multiple quadrants, with both probing depth and clinical attachment level ≥5 mm, and with bleeding on probing. The pockets were randomly distributed into four groups (n = 18 each) that received ultrasonic periodontal debridement in addition to placebo (the UPD group), systemic clarithromycin (the UPD + CLM group), aPDT (the UPD + aPDT group), or both systemic clarithromycin and aPDT (the UPD + CLM + aPDT group). The measurements were performed prior to treatment (baseline) and at 3 and 6 months postoperatively. The following parameters were evaluated: plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level. A 5% significance level was used in the statistical analysis. RESULTS: At 3 months, UPD + aPDT, UPD + CLM, and UPD + CLM + aPDT groups all exhibited reduced probing depths relative to the UPD group (p < 0.05). However, at 6 months, the reduction in mean probing depth was greater in the antibiotic groups (UPD+CLM and UPD+CLM+aPDT) than in the UPD and UPD+aPDT groups (p < 0.05). Regarding clinical attachment level, only the UPD+CLM+aPDT group presented a significant gain relative to the UPD and UPD + PDT groups (p < 0.05). CONCLUSIONS: Ultrasonic periodontal debridement has greater clinical advantages when associated with clarithromycin than with associated with aPDT. However, the joint application of aPDT and clarithromycin did not present additional benefits.

Clarithromycin as an Adjunct to One-Stage Full-Mouth Ultrasonic Periodontal Debridement in Generalized Aggressive Periodontitis: A Randomized Controlled Clinical Trial.

BACKGROUND: The aim of the present study is to evaluate the periodontal clinical and microbiologic responses and possible adverse effects of clarithromycin (CLM) combined with periodontal mechanical therapy in the treatment of patients with generalized aggressive periodontitis. METHODS: Forty patients were selected and randomly assigned into one of two groups: 1) CLM (n = 20): one-stage full-mouth ultrasonic debridement (FMUD) associated with CLM (500 mg, every 12 hours for 3 days); and 2) placebo (n = 20): FMUD associated with placebo pills. Clinical and microbiologic parameters were evaluated at baseline and 3 and 6 months postoperatively. RESULTS: Both treatments presented statistically significant clinical and microbiologic improvements. However, the CLM group presented lower means of probing depth for pockets ≥7 mm at 6 months (4.0 ± 1.7 mm) compared with the placebo group (4.7 ± 1.3 mm) (P = 0.04). In addition, the CLM group also presented greater reduction of Porphyromonas gingivalis (Pg) DNA counts at 6 months (P = 0.0001). CONCLUSION: Results from this study suggest both treatments are effective; however, adjunct use of CLM to FMUD leads to better reduction of deep pockets and Pg at 6 months compared with FMUD alone.

Microbiological outcomes from different periodontal maintenance interventions: a systematic review.

This study aimed to investigate the differences in the subgingival microbiological outcomes between periodontal patients submitted to a supragingival control (SPG) regimen as compared to subgingival scaling and root planing performed combined with supragingival debridement (SPG + SBG) intervention during the periodontal maintenance period (PMP). A systematic literature search using electronic databases (MEDLINE and EMBASE) was conducted looking for articles published up to August 2016 and independent of language. Two independent reviewers performed the study selection, quality assessment and data collection. Only human randomized or non-randomized clinical trials with at least 6-months-follow-up after periodontal treatment and presenting subgingival microbiological outcomes related to SPG and/or SPG+SBG therapies were included. Search strategy found 2,250 titles. Among these, 148 (after title analysis) and 39 (after abstract analysis) papers were considered to be relevant. Finally, 19 studies were selected after full-text analysis. No article had a direct comparison between the therapies. Five SPG and 14 SPG+SBG studies presented experimental groups with these respective regimens and were descriptively analyzed while most of the results were only presented graphically. The results showed that both SPG and SPG+SBG protocols of PMP determined stability in the microbiological results along time. Nevertheless, new studies comparing these interventions in PMP are needed, especially if the limitations herein discussed could be better controlled.
