Abstract Aim The present study aimed to systematically assess current evidence on effects of locally delivered antibiotics during periodontal surgery compared to periodontal surgery alone on clinical attachment level (CAL) gain, probing pocket depth (PPD) reduction, recession depth (RD) changes, gingival index (GI), bleeding on probing (BOP), and plaque index (PI). Methodology MEDLINE-PubMed, Cochrane-CENTRAL and Scopus databases were searched up to April 2021 for randomized clinical trials (RCT), evaluating effects of locally delivered antibiotics during periodontal surgery. CAL gain served as primary, while PPD reduction, RD changes, GI and PI as secondary outcomes. The Cochrane Risk of Bias Tool was used to assess possible bias. Data were extracted, and meta-analysis was performed where appropriate. Result Screening of 2314 papers resulted in nine eligible studies. No adverse events were reported. Data on outcome variables were pooled and analyzed using generic inverse variance model and presented as weighted mean difference (WMD) and 95% confidence interval (95% CI). Statistically significant improvements in favor of antibiotics’ delivery were observed in studies with follow-up of ≤6 months for CAL gain (WMD = 0.61 mm (95% CI [0.07, 1.14]; p = 0.03), PPD reduction (WMD = 0.41 mm (95% CI [0.02, 0.80]; p = 0.04)) and BOP (WMD = −28.47% (95% CI [−33.00, −23.94]); p < 0.001), while for GI improvements were notable for >6 to 12 months (WMD = −0.27 (95% CI [−0.49, −0.06]; p = 0.01)). Conclusion Within the current review’s limitations, locally delivered antibiotics during surgical periodontal therapy results in post-surgical improvements for CAL, PPD, and BOP (≤6 months) with a longer-lasting GI improvement. Further randomized controlled trials are needed with true periodontal end-points to assess the ideal antibiotic agent, dosage, and delivery methods. Clinical relevance Local delivery of antibiotics during periodontal surgery improved clinical parameters for up to 6-month follow-up, with beneficial longer effects on gingival inflammation. Within the current study’s limitation, the presented evidence could support the elective usage of locally delivered antibiotics during surgical periodontal therapy.

Abstract Background The aim of this meta-analysis was to evaluate the difference in treatment outcomes between sub-gingival placement of chlorhexidine chip (CHX chip) in adjunct to scaling and root planing (SRP) and SRP alone for the management of periodontal pockets in patients suffering from chronic periodontitis. Methods We searched the MEDLINE (PubMed), SCOPUS and CENTRAL databases and identified 15 randomized clinical trials published within the last decade (2007–2019): 9 with split-mouth design and 6 with parallel study design. We extracted data and performed both qualitative and quantitative syntheses. The primary outcomes assessed were gain in clinical attachment level (CAL), reduction in probing pocket depth (PPD), improvement in gingival inflammation, and results of microbiological assays. Results We used meta-analysis plots to assess all the clinical outcomes. The mean differences in PPD reductions at 1 month (MD 0.63), 3 months (MD 0.69), and 6 months (MD 0.75); and the CAL gains at 1 month (MD 0.54), 3 months (MD 0.64), and 6 months (MD 0.68) showed more favorable responses in sites treated with the CHX chip as an adjuvant to SRP, than in sites treated with SRP alone. Conclusion SRP with adjunctive CHX chips showed better clinical outcomes than SRP alone for the management of periodontal pockets in patients with chronic periodontitis.

This review aimed to rank the clinical efficacy of commercially available single-application local drug delivery and adjunctive agents (LDAs) compared with subgingival mechanical debridement (SMD) in nonsurgical periodontal therapy (NSPT). Randomized controlled clinical trials that compared LDAs against SMD alone or with placebo in adults (aged at least 18 years) diagnosed with periodontitis with a minimum of 6 months follow-up were included. A frequentist approach to random-effects network meta-analysis was implemented. The efficacies of the LDAs measured by probing pocket depth (PPD) reduction and clinical attachment level (CAL) gain were reported as mean difference (MD) with 95% confidence intervals (CIs). The treatments were ranked according to their P-score. Four network meta-analyses suggested that sulfonic/sulfuric acid gel (PPD MD −1.13 mm, 95% CI −1.74 to −0.53, P-score 0.91; CAL MD −1.09 mm, 95% CI −1.58 to −0.61, P-score 0.95) and doxycycline hyclate gel (PPD MD −0.90 mm, 95% CI −1.50 to −0.30, P-score 0.93; CAL MD −0.84 mm, 95% CI −1.40 to −0.28, P-score 0.92) were the most effective in reducing PPD and gaining CAL in split-mouth and parallel studies, respectively (moderate certainty of evidence). LDAs have differing efficacies, but they present with possible clinical significance over SMD alone in NSPT.

Abstract Background: Mechanical plaque removal has been commonly accepted to be the basis for periodontal treatment. This study aims to compare the effectiveness of ultrasonic and manual subgingival scaling at different initial probing pocket depths (PPD) in periodontal treatment. Methods: Public databases were searched. Weighted mean differences in PPD and clinical attachment loss (CAL) reduction were estimated by random effects model. Bleeding on probing (BOP), gingival recession (GR), and post-scaling residual dental calculus were analyzed by comparing the results of each study. Results: Ten randomized controlled trials were included out of 1,434 identified. Selected outcomes were PPD and CAL. Initial PPD and follow-up periods formed subgroups. For 3-month follow-up: (1) too few shallow initial pocket studies available to draw a conclusion; (2) the heterogeneity of medium depth studies was so high that could not be merged to draw a conclusion; (3) deep pocket studies showed no statistical differences in PPD and CAL reduction between ultrasonic and manual groups. For 6-month follow-up: (1) too few shallow initial PPD studies to draw a conclusion; (2) at medium pocket depth, PPD reduction showed manual subgingival scaling better than ultrasound. No statistical differences were observed in CAL reduction between the two approaches; (3) for deep initial PPD studies, both PPD and CAL reduction showed manual subgingival scaling better. GR results indicated no statistical differences at medium and deep initial pocket studies between the two methods. BOP results showed more reduction at deep pocket depths with manual subgingival scaling. No conclusion could be drawn about residual dental calculus. Conclusion: When initial probing pocket depth was 4-6mm, PPD reduction proved manual scaling superior to ultrasonic subgingival scaling, but CAL and GR results showed no statistical differences between the two means. When initial probing pocket depth was ≥6mm, PPD, CAL and BOP reductions suggested that manual subgingival scaling was superior to ultrasonic subgingival scaling, but GR results showed no statistical differences. No conclusion could be drawn about residual dental calculus.

Abstract Background: The aim of this systematic review and meta-analysis was to analyze the additive effects of the melatonin supplementation with nonsurgical periodontal therapy (NSPT) on periodontal status in patients affected by chronic periodontitis. Methods: In December 2020, We searched PubMed, EMBASE, Web of Science, CENTRAL databases and Google Scholar databases. Four RCTs were recruited with the same inclusion criteria. PD and CAL were the primary outcome measures. Subgroup analyses were performed according to health statuses and follow-up times, and Cochran’s Q and I-square ( I2 ) tests were used to assess heterogeneity.Results: This review included four RCTs. Four studies reported probing depth (PD) and 3 studies reported clinical attachment loss (CAL). Compared with the placebo groups, the melatonin groups showed a significant reduction in PD (weighted mean difference [WMD], -1.01; 95% confidence intervals [CI], -1.67 to -0.35; I2 = 76%) and CAL (WMD, -1.08; 95% CI: -1.36 to -0.79, I2 = 0%). Subgroup analyses revealed that the use of systemic melatonin + NSPT significantly reduced PD and CAL at the 2-, 3-, and 6-month follow-ups compared to NSPT alone, and stronger treatment effects of reducing PD were observed at shorter follow-ups than at longer follow-ups when adjunctive systemic melatonin was used.Conclusions: Melatonin supplementation in adjunct with nonsurgical periodontal therapy can moderately improve the efficacy of NSPT in reducing PD and greater CAL gain in patients with periodontitis. With the limited evidence available, it is evident that additional good quality RCTs are required to demonstrate additional beneficial effects of oral melatonin supplementation on periodontal clinical parameters after NSPT.

Abstract Objectives The aim of this systematic review and meta-analysis was to evaluate the efficacy of indocyanine green–mediated photodynamic therapy (ICG-PDT) as an adjunct to non-surgical periodontal therapy (NSPT), in the management of chronic periodontitis. Materials and methods Four electronic databases (PubMed, Cochrane Central Register of Controlled Trials, Embase via OVID, Web of Science) were searched for randomised controlled trials comparing NSPT with ICG-PDT to NSPT without laser therapy. Primary outcome measures were changes in probing pocket depth (PPD) and clinical attachment level (CAL). Clinical outcomes were extracted and pooled from 7 eligible trials and meta-analyses conducted using mean difference with standard deviations. Results For PPD, adjunctive ICG-PDT resulted in a mean additional reduction of 1.17 mm (95% CI: 0.67–1.66 mm) at 3 months and a mean additional reduction of 1.06 mm (95% CI: 0.54–1.57 mm) at 6 months. For CAL, adjunctive ICG-PDT resulted in a mean additional gain of 0.70 mm (95% CI: 0.17–1.23 mm) at 3 months and a mean additional gain of 1.03 mm (95% CI: 0.83–1.24 mm) at 6 months. No adverse events were reported in any studies. Conclusions The adjunctive use of ICG-PDT in NSPT results in improved treatment outcomes at 3 and 6 months post-therapy. Further investigation is needed to evaluate variables such as different photosensitiser concentrations and adjusting parameters associated with the light source. Clinical relevance Indocyanine green–based photosensitisers may be a novel, clinically efficacious agent for use in the management of periodontitis.

Abstract Purpose This study updates the current evidence on the role of allografts versus autografts for medial patellofemoral ligament (MPFL) reconstruction in patients with patellofemoral instability. Methods The study was performed according to the PRISMA guidelines. In March 2021, a literature search in the main online databases was performed. Studies reporting quantitative data concerning primary MPFL reconstruction using an allograft were considered for inclusion. The Coleman Methodology Score was used to assess the methodological quality of the selected articles. Results Data from 12 studies (474 procedures) were retrieved. The mean follow-up was 42.2 (15–78.5) months. The mean age was 21.1 ± 6.2 years. 64.9% (285 of 439) of patients were female. At the last follow-up, the Tegner (p < 0.0001), Kujala (p = 0.002) and the Lysholm (p < 0.0001) scores were minimally greater in the autografts. The similarity was found in the rate of persistent instability sensation and revision. The allograft group evidenced a lower rate of re-dislocations (p = 0.003). Conclusion Allografts may represent a feasible alternative to traditional autograft for MPFL reconstruction in selected patients with patellofemoral instability. Allograft tendons yielded similar PROMs, rates of persistent instability, and revision. Allograft reconstructions tended to have modestly lower re-dislocation rates. Level of evidence IV.

Abstract Background Reports of the effectiveness of e-cigarettes (ECs) for smoking cessation vary across different studies making implementation recommendations hard to attain. We performed a systematic review and meta-analysis to synthesise the current evidence regarding the effectiveness of ECs for smoking cessation. Methods PubMed, PsycInfo and Embase databases were searched for randomized controlled trials comparing nicotine ECs with non-nicotine ECs or with established smoking cessation interventions (nicotine replacement therapy (NRT) and or counselling) published between 01/01/2014 and 01/05/2019. Data from eligible studies were extracted and used for random-effects meta-analyses. Results Our literature review yielded 13190 publications with 10 studies being identified as eligible for systematic review, covering 8362 participants, and 8 for meta-analyses (n = 30 - 6006). Using the last follow-up of eligible studies, the proportion of smokers achieving abstinence was 1.67 [95CI:0.99 - 2.81] times higher in nicotine EC users compared to non-nicotine EC users. The proportion of abstinent smokers was 1.69 [95CI:1.25 - 2.27] times higher in EC users compared to participants receiving NRT. EC users showed a 2.70 [95CI:1.15 - 6.30] times higher proportion of abstinent smokers in comparison to participants solely receiving counselling. Conclusions Our analysis showed modest effects of nicotine-ECs compared to non-nicotine ECs. When compared to NRT or counselling, results suggest that nicotine EC may be more effective for smoking cessation. As ECs also help maintaining routinized behaviour and social aspects of smoking, we hypothesise that this may explain their advantage as a tool for smoking cessation. However, given the small number of included studies, different populations, heterogeneous designs, and the overall moderate to low quality of evidence, it is not possible to offer clear recommendations. More comparable data is needed to strengthen confidence in the quality of evidence. Key messages The number of previous studies assessing the effectiveness of ECs for smoking cessation is limited. Further, comparability of these studies is restricted, weakening the quality of evidence. Although current evidence on the effectiveness of ECs for smoking cessation is inconclusive, our meta-analyses suggest that ECs could be a promising alternative tool in attempts to achieve abstinence.

Background: There have been a few systematic reviews and conventional meta-analyses reporting effect of drugs on metabolic disturbance induced by atypical antipsychotics (AAPs). However, few of them provided sufficient and comprehensive comparisons between pharmacological interventions. Aims: We aimed to qualitatively compare drugs’ effect on AAPs-induced metabolic abnormalities by using network meta-analysis (NMA). Methods: We searched PubMed, EMBASE, Web of Science, Cochrane Controlled Register of Trials (CENTRAL), and PsycINFO on March 26, 2019. Of 5889 records identified, 61 randomized clinical trials including 3467 participants were included. We estimated weighted mean difference (WMD) and odds ratio (OR) using NMA. We assessed the risk of bias of individual studies with the Review Manager 5.3. Primary outcomes included change of body weight and body mass index (BMI). Secondary outcomes included change of other cardiometabolic risk factors, acceptability, and tolerability. Results: For body weight, topiramate (WMD −5.4, 95% CI −7.12 to −3.68), zonisamide (−3.44, 95% CI −6.57 to −0.36), metformin (−3.01, 95% CI −4.22 to −1.83), glucagon-like peptide-1 receptor agonists (GLP-1RAs) (−3.23, 95% CI −5.47 to −0.96), and nizatidine (−2.14, 95% CI −4.01 to −0.27) were significantly superior to placebo. Results regarding to BMI were similar to that of body weight. With respect to tolerability, only topiramate (OR 24, 95% CI 3.15 to 648) was inferior to placebo. Conclusions: Considering both efficacy and tolerability, evidence from this NMA indicates zonisamide, metformin, GLP-1RAs, and nizatidine in adults should be the first-line treatment for alleviating AAPs-induced weight gain or elevated BMI.

Phenytoin-induced gingival overgrowth (PIGO) is a common complication of the continuous use of medications. This paper presents a case of PIGO hindering oral function and compromising oral hygiene and aesthetics, which was treated with a combination of nonsurgical and surgical periodontal therapies. A 39-year-old male patient was referred for dental treatment with several complaints, especially upper and lower gingival overgrowth that hindered speech and swallowing. Generalized deep probing pockets and bone loss were detected. Diagnosis of gingival overgrowth associated with phenytoin and chronic periodontitis was established. The treatment plan consisted of conservative therapy with education on oral health, motivation and meticulous oral hygiene instruction in combination with scaling and root planing. During the revaluation period, a marked reduction in the clinical parameters was noted, particularly probing pocket depth reduction. Surgical therapy for removal of gingival overgrowth was also performed to achieve pocket reduction. Supportive periodontal therapy was proposed and the patient is currently under follow-up for 4 years. Management of PIGO may be obtained by the use of periodontal procedures combined with good oral hygiene and periodontal supportive care.

Importance Mostantiseizure medications (ASMs) carry a US Food and Drug Administration–mandated class label warning of increased suicidality risk, based on a meta-analysis comparing suicidality between individuals treated with medications vs placebo in randomized clinical trials done before 2008. ASMs approved since then carry this warning although they were not similarly studied. Objective To review all placebo-controlled phase 2 and 3 studies of 10 ASMs approved since 2008 to evaluate the risk of suicidality of these drugs compared with placebo. Data Sources Primary publications and secondary safety analyses in PubMed of all phase 2 and 3 randomized placebo-controlled epilepsy trials of ASMs approved since 2008, using keywords epilepsy, antiepileptic drugs, seizures, suicidality, suicidal ideation, and the names of individual drugs. Study Selection All phase 2 and 3 randomized clinical trials of adjunctive treatment of drug-resistant epilepsy and their secondary safety analyses. Data Extraction and Synthesis Articles were reviewed for frequency of suicidality (ideation, attempts, and completed suicides). Mode of suicidality ascertainment included treatment-emergent adverse event reports, Standardized Medical Dictionary for Regulatory Activities queries for events in prespecified categories including suicidal ideation and behavior, prospective collection of suicidality data as a prespecified safety outcome using the Columbia-Suicide Severity Rating Scale, and retrospective evaluation by blinded review using the Columbia-Classification Algorithm of Suicide Assessment. A meta-analysis compared risk for drugs vs placebo of each outcome for all drugs overall and by individual drugs and trials. Main Outcomes and Measures Suicidality (total and by ideation), attempts, and completed suicides. Results Excluding studies that did not evaluate suicidality (everolimus and fenfluramine) or did not evaluate it prospectively (lacosamide, ezogabine, and clobazam), 5 drugs were analyzed: eslicarbazepine, perampanel, brivaracetam, cannabidiol, and cenobamate. Suicidality was evaluated in 17 randomized clinical trials of these drugs, involving 5996 patients, of whom 4000 patients were treated with ASMs and 1996 with placebo. There was no evidence of increased risk of suicidal ideation (drugs vs placebo overall risk ratio, .75; 95% CI, .35–1.60) or attempt (risk ratio, .75; 95% CI, .30–1.87) overall or for any individual drug. Suicidal ideation occurred in 12 of 4000 patients treated with ASMs (.30%) vs 7 of 1996 patients treated with placebo (.35%) ( P  =  .74). Three patients treated with ASMs and no patients treated with placebo attempted suicide ( P  =  .22). There were no completed suicides. Conclusions and Relevance There is no current evidence that the 5 ASMs evaluated in this study increase suicidality in epilepsy and merit a suicidality class warning
