RESUMO
PURPOSE: The aim of the present systematic review and meta-analysis was to assess the efficacy of non-surgical periodontal therapy (NSPT) with adjunct photodynamic therapy (aPDT) in reducing periodontal inflammation and haemoglobin A1c (HbA1c) levels in patients with diabetes mellitus (DM). MATERIALS AND METHODS: The focused question was 'Does NSPT with adjunct aPDT help reduce periodontal inflammation and HbA1c levels in patients with DM?' The PICO (patient/population, intervention, comparison and outcomes) was formatted as follows: Patients (P): Participants diagnosed with DM; Intervention (I): NSPT with adjunct PDT for the treatment of periodontitis; Control (C): NSPT alone or NSPT with adjunct systemic antibiotic therapy; and Outcome (O): Changes in HbA1c levels. The inclusion criteria comprised RCTs specifically evaluating the impact of NSPT on HbA1c levels in diabetic patients, with a specific focus on interventions involving NSPT with and without adjunct aPDT. The literature search was performed in accordance with the Preferred reporting items for systematic reviews and meta-analysis. Indexed databases were searched without time and language restrictions using various keywords. Forest plots were created to illustrate the effects of the different studies and the global estimation. RESULTS: Five RCTs were included and processed for data extraction. The number of participants ranged from 12 to 45 patients with medically diagnosed type-2 DM. In all RCTs, aPDT was done using a diode laser with wavelengths ranging between 660 and 810 nm. Three and two RCTs had moderate and high RoB, respectively. In two RCTs, NSPT with adjunct aPDT reported no improvement in clinical periodontal parameters. Two studies reported that NSPT with adjunct aPDT significantly reduces periodontal probing depth compared to NSPT alone. Four of the five RCTs reported that NSPT+PDT does not influence HbA1c levels. CONCLUSIONS: NSPT with or without adjunct aPDT does not affect HbA1c levels in patients with type-2 DM.

Tea tree (Melaleuca alternifolia) oil (TTO) is an antimicrobial agent, and hence, its use in fabricating nanoparticles (NP) may be useful in providing more efficacious antimicrobial agents. The current research aimed to test the antimicrobial efficacy of TTO and its TTO-Metal-NPs against oral microbes: Porphyromonas gingivalis, Enterococcus faecalis, and Streptococcus mutans. The antimicrobial activity of TTO and zinc (Zn) and iron (Fe) nanoparticles (NPs) and the combined effects of antimicrobial agents were investigated using agar well diffusion assays. Fourier-transform infrared spectroscopy (FT-IR) was used to identify the phyto-constituents of TTO. Field emission scanning electron microscopy (FE-SEM), dynamic light scatter (DLS), and zeta potential were utilized to analyze the biogenic nanoparticles' morphology, size, and potential. The antimicrobial mode of action was determined by assessing the morphological changes under scanning electron microscopy (SEM). The TTO extracts converted Zn and Fe ions to NPs, having an average size of 97.50 (ZnNPs) and 102.4 nm (FeNPs). All tested agents had significant antibacterial efficacy against the tested oral microbes. However, the TTO extract was more efficacious than the NPs. Combination treatment of TTO with antibiotics resulted in partial additive effects against P. gingivalis and partial antagonistic effects against E. faecalis, S. mutans, and common mouthwashes (Oral B and chlorhexidine). TTO and NP-treated bacteria underwent morphological changes on treatment. M. alternifolia phytochemicals could be useful for further research and development of antimicrobial NPs. The current study highlights the variance in activity observed for different types of bacteria and antagonistic effects seen with common mouthwashes, which represent a threat to therapeutic efficacy and heighten the risk of clinical microbial resistance.

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRI) are commonly used for managing psychological diseases such as depression. These disorders are also directly associated with periodontal and peri-implant diseases, namely periodontitis and peri-implantitis, respectively. It is hypothesized that there is no difference in periodontal and peri-implant clinicoradiographic status and unstimulated whole salivary interleukin (IL)-1ß levels in participants using selective serotonin reuptake inhibitors (SSRI) and controls (individuals not using SSRI). The aim of the present observational case-control study was to compare periodontal and peri-implant clinicoradiographic statuses and whole salivary IL-1ß in participants using SSRI and controls. METHODS: Users of SSRI and controls were included. In all participants, periodontal (plaque index [PI], gingival index [GI], probing depth [PD], clinical attachment loss [AL] and marginal bone loss [MBL]) and peri-implant (modified PI [mPI], modified GI [mGI], PD and crestal bone loss [CBL]) were assessed. Unstimulated whole saliva was collected and IL-1ß levels were determined. Information related to duration of implants in function, duration of depressive symptoms and treatment of depression was retrieved from healthcare records. Sample-size was estimated using 5% error and group comparisons were performed. P < 0.05 was considered statistically significant. RESULTS: Thirty-seven SSRI users and 35 controls were assessed. Individuals using SSRI had a history of depression of 4.2 ± 2.5 years. The mean age of SSRI-users and controls were 48.7 ± 5.7 and 45.3 ± 5.1 years, respectively. Tooth brushing twice daily was reported by 75.7% and 62.9% SSRI-users and controls, respectively. There was no statistically significant difference in PI, mPI, GI, mGI, PD, clinical AL, numbers of MT and mesial and distal MBL and CBL among individuals using SSRI compared with controls (Tables 3 and 4). The unstimulated whole salivary flow rate in individuals using SSRI and controls was 0.11 ± 0.003 and 0.12 ± 0.001 ml/min, respectively. Whole salivary IL-1ß levels in individuals using SSRI and controls were 57.6 ± 11.6 pg/ml and 34.6 ± 5.2 pg/ml, respectively. CONCLUSION: Users of SSRI and controls demonstrate healthy periodontal and peri-implant tissue statuses with no marked differences in whole salivary IL-1ß levels provided oral hygiene is stringently maintained.

OBJECTIVE: There are no studies that have evaluated the effect of Alveogyl with and without adjunct photobiomodulation therapy (PBMT) in reducing self-rated post-operative pain (SPP) in patients with alveolar osteitis (AO; dry socket). The aim of the present randomised controlled trial was to assess the effectiveness of Alveogyl with and without PBMT for the management of SPP in patients with AO. METHODS: Adult nonsmokers with diagnosed AO were included. Patients were randomly divided into 4 groups. In Group 1, patients underwent mechanical curettage (MC) with copious normal saline irrigation. In Group 2, patients underwent MC + Alveogyl dressings in extraction sites which were changed every 48 hours until cessation of pain. In Group 3, patients underwent MC + Alveogyl followed by PBMT using a 660-nm indium-gallium-aluminum-phosphide diode laser. In Group 4, patients were treated solely with PBMT. The visual analogue scale was used up to 3 postoperative days to assess SPP up to 3 days at 6- (T0) and 12-hour (T1) intervals. Statistical analyses were performed using the analysis of variance and Bonferroni post hoc adjustment tests. Correlation between SPP scores and age, sex, and eruption status of teeth was assessed using logistic regression models. P values <.01 were nominated as being statistically significant. RESULTS: In all, 14, 13, 14, and 14 individuals with AO were included in groups 1, 2, 3 and 4, respectively. All patients had undergone extraction of mandibular third molars. At baseline and on day 1, there was no difference in SPP in all groups. On days 2 and 3, mean visual analogue scale (VAS) scores at T1 (P < .01) and T2 (P < .01) intervals were significantly high in Group 2 compared with Group 3. On days 2 and 3, mean VAS scores at T1 (P < .01) and T2 (P < .01) intervals were significantly high in Group 4 compared with Group 3. There was no difference in SPP in groups 3 and 4 on day 3 at T0 and T1 intervals. CONCLUSIONS: PBMT following MC and Alveogyl dressing is more efficient in reducing SPP compared with MC with or without Alveogyl dressing in patients with AO.

OBJECTIVE: Whole-salivary (WS) adiponectin and leptin levels after scaling and root planing (SRP) with and without antimicrobial-photodynamic-therapy (aPDT) in obese and normal-weight individuals with periodontitis remain uninvestigated. This study compared the effect of SRP without and with adjuvant aPDT on periodontal status and WS leptin and adiponectin levels (LAL) in obese patients with periodontitis. METHODS: Groups 1 and 2 entailed obese patients without and with periodontitis. Groups 3 and 4 had normal weight individuals without and with periodontitis. Therapeutically, individuals with periodontitis were categorized into test- (SRP+aPDT) and control- (SRP alone) subgroups. All patients without periodontitis underwent routine dental prophylaxis. Clinical attachment loss (AL), gingival and plaque index (GI and PI), probing depth (PD), missing teeth (MT) and WS LAL were measured at baseline and at three months of follow-up. P<5% were graded statistically significant. RESULTS: At baseline, clinicoradiographic variables were significantly higher among patients in test- and control-groups in groups 1 (P<0.01) and 3 (P<0.01) versus 2 and 4. In group 2 and 3, LL were significantly high at baseline compared with follow-up (P<0.01). There was no difference in periodontal parameters and WS adiponectin and LL in the test and control-groups at of follow-up. No correlation existed between salivary LAL and clinical periodontal parameters (PI, GI, PD and clinical AL). No correlation existed between age, gender and BMI and WS LAL. CONCLUSION: In the short-term, SRP with or without aPDT is ineffective in the treatment of periodontitis in obese patients with periodontitis.

INTRODUCTION: The aim of the present randomized controlled trial was to assess the effect of mechanical instrumentation (MI) with adjunct photodynamic therapy (PDT) on salivary tumor necrosis factor-alpha (TNFα) levels and clinical periodontal and periimplant status in patients with depression. MATERIALS AND METHODS: In groups 1 and 2, individuals with periodontal and periimplant diseases with and without depression, respectively were included. Group-3 comprised of systemically healthy individuals with a healthy periodontal and periimplant status. In groups 1 and 2, patients in the test- and control groups received MI with and without PDT respectively. Periodontal and periimplant probing depth and plaque and gingival indices were measured. Radiographic evaluation was done at baseline. Whole salivary tumor necrosis factor alpha (TNFα) in periimplant sulcular fluid were measured at baseline. The clinical and immunological parameters were reassessed at 120 days' follow-up. Level of significance was set at P<0.05. RESULTS: Thirty-four, 36 and 37 implants were in function in groups 1, 2 and 3, respectively. At baseline, periodontal and periimplant clinical parameters and TNFα levels were significantly higher in groups 1 (P<0.05) and 2 (P<0.05) than Group-3. At 4-months follow-up, there was no difference in periodontal and periimplant clinical parameters in the test- and control groups among individuals in groups 1 and 3. In Group-2, there was a significant reduction in periodontal (P<0.05) and periimplant (P<0.05) clinical parameters at 4-months follow-up than baseline. In Group-2, there was no significant difference in these parameters among patients in the test- and control-groups. CONCLUSION: In patients with depression clinical periodontal and periimplant status is poorer and salivary TNFα levels are higher after MI with or without PDT. In healthy patients, PDT offers no additional benefits in the treatment of periodontal inflammation.

The aim was to compare the in-vitro antibacterial effectiveness of two herbal extracts (a) Saussurea-costus (S. costus) and (b) Melaleuca-alternifolia (M. alternifolia) against Porphyromonas gingivalis (P. gingivalis), Streptococcus mutans (S. mutans) and Enterococcus faecalis (E. faecalis). Aqueous extracts from M. alternifolia were prepared by adding 2 grams of S. costus and M. alternifolia, respectively to 100 ml distilled water. Bacterial strains of P. gingivalis, E. faecalis and S. mutans were treated into 3 groups. In groups 1 and 2, bacterial strains were treated with aqueous extracts of S. costus and M. alternifolia, respectively. In the control-group, bacterial strains were exposed to distilled water. Antibacterial activity of the samples and nanoparticles was determined. The minimum-inhibitory-concentration (MIC) values were determined using the microdilution method. P < 0.01 was considered statistically significant. The MIC for all bacterial strains treated with S. costus was significantly higher than that of M. alternifolia (P < 0.001). There was no significant difference in MIC for strains of P. gingivalis, E. faecalis and S. mutans treated with S. costus. For bacterial strains treated with M. alternifolia, the MIC was significantly higher for P. gingivalis compared with E. faecalis and S. mutans strains (P < 0.01). There was no difference in MIC for E. faecalis and S. mutans strains treated with M. alternifolia. The in-vitro antibacterial efficacy of M. alternifolia is higher than S. costus against P. gingivalis, E. faecalis and S. mutans.
RESUMO
OBJECTIVE: The aim was to assess the influence of a single session of antimicrobial photodynamic therapy (aPDT) as an adjunct to non-surgical scaling and root planing (SRP) in reducing periodontal inflammation and subgingival presence of Porphyromonas gingivalis (P. gingivalis) and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans) in patients with periodontitis. METHODS: Patients diagnosed with periodontitis were included. Information regarding age and gender was recorded using a questionnaire. All patients underwent full mouth non-surgical SRP and the following parameters were assessed at baseline: (a) marginal bone loss (MBL); (b) probing depth (PD) (c) clinical attachment loss (CAL); and (d) presence of supra-and subgingival bleeding and plaque (GI and PI). Identification of A. actinomycetemcomitans and P. gingivalis was performed using polymerase chain reaction. For aPDT (test-group), methylene-blue (MB) (0.005%) was used as photosensitizer and it was applied over and inside the buccal pockets of teeth. Using a Diode laser at 660 nm and 150 mW, irradiation was performed All clinical parameters except for MBL and microbiological evaluations were re-assessed at 3-months of follow-up. Level of significance was set at P<0.05. RESULTS: At 3-months of follow-up A. actinomycetemcomitans and P. gingivalis were identified in significantly lower number of patients in groups 1 and 2 compared with their respective baseline values. Number of patients in whom A. actinomycetemcomitans and P. gingivalis were identified at 3-months of follow-up were similar in both groups. At baseline, there was no statistically significant difference in PI, GI, PD, CAL and MBL among patients in groups 1 and 2. In groups 1 and 2, scores of PI (P<0.001), GI (P<0.001) and PD (P<0.001) were significantly higher at baseline compared with their respective 3-months' follow-up scores. CONCLUSION: One application of aPDT with non-surgical SRP is ineffective in managing periodontal inflammation and presence of P. gingivalis and A. actinomycetemcomitans in periodontitis patients.

The aim was to compare the peri-implant clinical and radiographic inflammatory parameters and whole salivary cotinine levels among cigarette smokers (CS), waterpipe smokers (WS) and never-smokers (NS). Thirty-four CS (Group 1), 33 WS (Group 2), and 31 NS (Group 3) were included. Peri-implant plaque index (PI), bleeding-on-probing (BOP), and probing depth (PD) were measured, and crestal bone loss (CBL) was assessed on standardized digital radiographs. Unstimulated whole saliva samples were collected and whole salivary cotinine levels were measured. Peri-implant PI and PD were higher in Groups 1 (P < 0.05) and 2 (P < 0.05) than in Group 3. Peri-implant BOP was significantly higher in Group 3 than in Groups 1 (P < 0.01) and 2 (P < 0.01). Peri-implant MBL was significantly higher in Groups 1 (P < 0.05) and 2 (P < 0.05) than in Group 3. There were significant differences in PI, BOP, PD, and CBL between Groups 1 and 2. There was no significant difference in the whole salivary cotinine levels in Groups 1 and 2. Peri-implant sites with plaque accumulation, PD, CBL, and whole salivary cotinine levels were higher in CS and WS than in NS, but did not differ between CS and WS.
