Efficacy of photobiomodulation following L-PRF application for recovery of mental nerve neurosensory disturbances caused by genioplasty: A randomized triple-blind clinical trial.

The present study assessed the efficacy of photobiomodulation (PBM) following leukocyte-platelet rich fibrin (L-PRF) application for recovery of mental nerve neurosensory disturbances (NSDs) caused by genioplasty. This randomized triple-blind split-mouth clinical trial was conducted on 20 female patients (40 quadrants) requiring genioplasty. In each patient, one random side of the mandible served as the intervention (laser), and the other side as the control group. After genioplasty and L-PRF application, the intervention side underwent GaAIAs diode laser irradiation (880 nm, 500 mW, 15 J/cm2, 0.5 cm2 spot size, continuous-wave). Each point was laser irradiated for 15 s. Unilateral extraoral PBM was performed at 1, 3, 7, 14, 21, and 28 days, postoperatively. Laser in off mode (sham laser) was used for the control side. A visual analog scale (VAS) was used for general sensitivity, and 2-point discrimination, directional discrimination, pain discrimination, and thermal discrimination tests were used to assess the neurosensory recovery at 2 days, 2 weeks, 4 weeks, and 2 months, postoperatively. Statistical analyses were performed using two-way repeated measures ANOVA, Bonferroni test, and generalized estimating equation (alpha = 0.05). Time had a significant effect on improvement of all sensory variables (P < 0.05). Neurosensory recovery was significantly better in the intervention than the control group at all time points according to the two-point discrimination test (P = 0.0135) and brush test (P = 0.025) results. The interaction effect of time and intervention was not significant on any dependent variable (P > 0.05). Application of L-PRF + PBM resulted in significantly greater sensorineural recovery according to the two-point discrimination and brush test results.

3Mixtatin versus MTA in pulp therapy of primary teeth: a systematic review and meta-analysis of current randomized controlled trials.

AIM: 3Mixtatin (a combination of Metronidazole, Minocycline, and Ciprofloxacin along with statins) is a novel biomaterial in pulp therapy, while Mineral Trioxide Aggregate (MTA) is considered the gold standard in endodontics. This study aimed to compare the clinical and radiographic success rates of MTA and 3Mixtatin in pulp therapy of primary teeth. METHODS AND MATERIALS: MEDLINE (PubMed), CENTRAL, Web of Science, Scopus, ProQuest databases, and Google Scholar were searched to identify randomized controlled trials (RCTs) on pulp therapy with 3Mixtatin and MTA in primary teeth, published up to February 2023. It should be noted that the protocol was previously registered in the International Prospective Register of Systematic Reviews (PROSPERO; CRD42021243626). RCTs were assessed independently by two researchers in terms of eligibility and quality. Data extracted and tabulated. The Cochrane Risk of Bias (RoB-2) tool was used to assess the risk of bias. The effect sizes were evaluated utilizing risk ratios (RRs). The heterogeneity investigation was conducted utilizing I² measurement at α = 0.10. RESULTS: Out of 86 retrieval records, four articles met the inclusion criteria. Based on clinical and radiographic outcomes, the application of 3Mixtatin in the pulp therapy of primary teeth was as successful as MTA in 12 months (Clinical RR = 1.087 | Radiographic RR = 2.132). The RoB-2 tool showed a low risk of bias in all included RCTs. CONCLUSION: The limited evidence showed the clinical and radiographic efficacy of 3Mixtatin as a potential alternative to MTA. Further empirical research with larger sample sizes and strict methodology will be essential to substantiate this assertion.

The Effect of Photobiomodulation on Temporomandibular Pain and Functions in Patients With Temporomandibular Disorders: An Updated Systematic Review of the Current Randomized Controlled Trials.

Introduction: Temporomandibular disorders (TMDs) are the most prevalent non-dental origin orofacial pain conditions affecting the temporomandibular joints (TMJs) and/or orofacial muscles. Photobiomodulation therapy (PBMT) is a conservative way to improve function and reduce symptoms in TMD patients. This systematic review was conducted to update evidence about the effects of PBMT on pain intensity, TMJ movements, electromyography (EMG) activity, pressure pain threshold (PPT), and TMJ sound in patients with TMDs. Methods: A systematic literature search was conducted in Web of Science, PubMed/Medline, and Scopus databases using appropriate keywords and specific strategies from January 2000 to September 2022. Data extraction was done based on the inclusion/exclusion criteria. Results: A total of 40 studies were included. All included studies except one provided information on pain intensity; 27 studies showed a reduction in pain intensity in PBMT groups compared to control groups. Seven out of 15 studies, which reported maximum mouth opening (MMO), showed a greater MMO in PBMT groups than in placebo groups. In addition, the figures for passive maximum mouth opening (PMMO) and active maximum mouth opening (AMMO) in all the studies reporting PMMO and AMMO were higher in PBMT groups. In eight out of ten studies, lateral movement (LM) was greater in PBMT groups. Moreover, in three studies out of four, protrusive movement (PM) was reported to be greater in the PBMT group. Four out of nine studies showed a greater PPT in the PBMT group. Reduced TMJ sounds in the PBMT group were reported in two out of five studies. In addition, in most studies, no difference in EMG activity was detected between the two groups. Conclusion: This updated systematic review showed the promising effects of PBMT on the alleviation of pain and improvement in MMO. Using the infrared diode laser with a wavelength ranging between 780-980 nm, an energy density of<100 J/ cm2, and an output power of≤500 mW for at least six sessions of treatment seems to be a promising option for treating mentioned TMDs signs and symptoms based on the previously reported findings.

Effectiveness of Cyanoacrylate in the Treatment of Dentin Hypersensitivity: A Systematic Review.

Objective: To compare the effectiveness of cyanoacrylate to other treatments or placebo in the management of dentin hypersensitivity (DH). Materials and Methods: The present review was organized based on the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. The search aimed to answer the following question: is cyanoacrylate effective in the treatment of DH when compared to other treatments or placebo? The following databases were used: PubMed/MEDLINE, Scopus, BVS, Web of Science, Cochrane, Clinicaltrials.gov, Portal Periódicos Capes, Google Scholar, and manual search. The evaluation process started with the information collected from the selected articles according to the Consolidated Standards of Reporting Trials (CONSORT). Results: Two randomized and five nonrandomized clinical trials were analyzed in the qualitative synthesis. The studies presented different cyanoacrylate formulations, different scales for evaluating pain, and different methods for provoking a painful stimulus. Cyanoacrylate-based products reduce DH in shorter follow-up periods and this reduction persisted throughout the study. The results varied according to the methods used to stimulate the pain. Only two articles showed a low risk of bias and a high level of scientific evidence. Conclusion: Although there is a limited number of studies in the scientific literature with appropriate methodological quality, the available evidence proves the effectiveness of cyanoacrylate in the treatment of DH. Clinical Relevance. Cyanoacrylate is easy to access, effective, easily applicable, and a low-cost product with satisfactory results.

Efficacy of Probiotics Compared to Chlorhexidine Mouthwash in Improving Periodontal Status: A Systematic Review and Meta-Analysis.

Purpose: To critically evaluate the available literature and conduct a systematic review of recent randomized controlled trials to assess the effectiveness of probiotics compared to chlorhexidine mouthwash in enhancing periodontal health. Methods: Five databases were searched electronically, as well as the gray literature. Using the Cochrane risk-of-bias tool for randomized clinical trials, the risk of bias was examined. The weighted mean difference (WMD) method was used to calculate the effect sizes. Heterogeneity was assessed using I 2 and τ 2 statistics. The GRADE approach was adopted to assess the certainty of the evidence. To assess the robustness of the findings, sensitivity analysis and publication bias assessment were undertaken. Results: A total of 1850 studies were initially identified. Sixteen clinical trials were eligible for qualitative synthesis, and ten were included in the meta-analysis. In terms of the gingival index, in total, no statistically significant difference was observed between chlorhexidine and probiotics within 4 weeks (WMD -0.03, 95% CI: -0.09∼0.04, P = 0.3885). Similar to GI, no statistically significant difference was observed between chlorhexidine and probiotics regarding the plaque index within 4 weeks (WMD 0.11, 95% CI: -0.05∼0.28, P = 0.1726). No statistically significant difference was observed between chlorhexidine and probiotics in all time intervals regarding oral hygiene index-simplified (WMD -0.01, 95% CI: -0.05∼0.04, P = 0.7508). The robustness of these findings was confirmed by sensitivity analysis and publication bias assessments. Conclusions: Based on the findings, probiotics were an acceptable alternative to conventional chlorhexidine in improving periodontal health. High-quality studies with rigorous methodology should be conducted to assess the optimum doses of probiotics for clinical implications.

Nonpharmacological Complementary Interventions for the Management of Pain after Third Molar Surgery: An Umbrella Review of Current Meta-Analyses.

Objectives: To provide a nonbiased, complete assessment of what the evidence from meta-analyses informs us about complementary and nonpharmacological treatment options for the management of pain after third molar surgery, as well as highlight any discordancy, gaps, or lack of evidence among meta-analyses. Methods: The quality of the included systematic reviews was assessed using the ROBIS tool. Corrected covered area (CCA) was calculated for pairs of similar meta-analyses to identify the amount of overlap. Reviews that were the most recent, comprehensive, and had adequate quality were considered for analyses when reviews showed a high overlap. In cases with a low amount of overlap among meta-analyses, all eligible studies were included. Also, citation matrices were constructed to address overlap. A network meta-analytical approach was adopted to rank different interventions. Results: Ten meta-analyses were included for quantitative synthesis. The quantitative analysis revealed that platelet-rich fibrin and its derivatives as well as ozone therapy reduce early and late pain better than the other complementary interventions compared to control (no complementary intervention). Conclusions: Despite the shortcomings of included meta-analyses, consolidated evidence suggests that platelet-rich-fibrin and its derivatives as well as ozone therapy outperform the other nonpharmacological complementary interventions in reducing early and late postsurgical pain following third molar extraction. However, the results should be interpreted with caution due to an unclear risk of bias and lack of firm evidence in the included meta-analyses. Moreover, there is a need for a standard protocol for the application of nonpharmacological complementary interventions.

The Role of Photobiomodulation on Dental-Derived Mesenchymal Stem Cells in Regenerative Dentistry: A Comprehensive Systematic Review.

BACKGROUND: Photobiomodulation therapy involves exposing tissues to light sources, including light-emitting diodes or low-level lasers, which results in cellular function modulation. The molecular mechanism of this treatment is revealed, demonstrating that depending on the light settings utilized, it has the potential to elicit both stimulatory and inhibitory reactions. OBJECTIVE: The current systematic review aimed to evaluate the impact of photobiomodulation therapy on dental stem cells and provide an evidence-based conclusion in this regard. METHODS: This systematic review was performed and reported based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) revised guidelines. PICO(S) components were employed to define the inclusion criteria. Web of Science, Scopus, Medline as well as grey literature, and google scholar were searched up to September 2021 to retrieve relevant papers. RESULTS: Photobiomodulation therapy showed promising effects on the proliferation, viability, and differentiation of dental stem cells. This finding was based on reviewing related articles with a low risk of bias. CONCLUSION: Despite the positive benefits of photobiomodulation therapy on dental stem cells, the current data do not provide a definitive conclusion on the best physical parameters for enhancing cell viability, proliferation, and differentiation.

PURPOSE: This study aimed to identify and rank the top 100 cited papers related to third molar surgery METHODS: This bibliometric analysis was performed through the Clarivate Analytics' Web of Science database intended to find the top 100 most cited papers. The search was conducted on 18th November 2021 with MeSH terms related to the third molar surgery. Extracted Data included title, main author, institution, publication year, a total of citations, citation average per year, country, the journal paper was published, journal impact factor, the number of citations of the three most-cited journals, study design, and field related to third molar surgery RESULTS: The top-cited paper was a retrospective cohort related to complications after the third molars surgery, published in 2003 in the Journal of Oral and Maxillofacial Surgery. The total number of citations was 9026. Thirty-nine percent of the papers included were randomized clinical trials. The USA is the main country responsible for the best publications in the field of third molar surgery. European researchers had the main expressive citation score, and "surgery" related to the third molar was the most critical field of research CONCLUSIONS: 1) The United States of America was the leading country that contributed to third molar field research 2) The Universities of Barcelona and the University of North Carolina were the most productive institutions regarding this research field; 3) Complications after third molar surgery was the most researched field. Compared to the other fields in dentistry such as Oral pathology and Cariology, the number of citations regarding third molar surgery was low.

Clinical and radiographic comparison of Biodentine and Formocresol: an updated meta-analysis with trial sequential analysis.

PURPOSE: This meta-analysis aimed to compare the clinical and radiographic success rate of Biodentine as an alternative to Formocresol to provide a critical appraisal of the available literature and evidence-based conclusion as well as update the previous systematic review. METHODS: MEDLINE, CENTRAL, Web of Science, Scopus, and Google Scholar databases were searched up to 20 October 2021 to identify RCTs evaluating pulpotomy with Biodentine/Formocresol in carious primary molars among children ≤ 10 years old. The risk of bias was assessed using the Cochrane RoB-2 tool. RRs and corresponding 95% CIs were calculated to pool results that RR Ëƒ 1 indicated a higher success rate in the Biodentine group and RR < 1 indicated a higher success rate in the Formocresol group. Heterogeneity was calculated using the I2 and τ2 statistics. In addition, trial sequential analysis was performed to adjust results for type I and type II errors and evaluate power of the meta-analysis. RESULTS: Nine RCTs were identified and eight RCTs were included in the meta-analysis and trial sequential analysis. The obtained evidence showed no significant difference between Biodentine and Formocresol in terms of clinical efficacy. However, considering the radiographic success rate the results of the meta-analysis and trial sequential analysis significantly favoured Biodentine. CONCLUSION: Within the limitations of the present review and based on the retrieved findings it has been clearly shown that Biodentine is superior compared to Formocresol in terms of radiographic success rate with firm evidence in this regard. Although the performed meta-analysis showed no significant clinical difference between Biodentine and Formocresol, however, trial sequential analysis revealed a lack of firm evidence in this regard.

The application of injectable platelet-rich fibrin in regenerative dentistry: A systematic scoping review of In vitro and In vivo studies.

Background: Ongoing research in the dental field has begun to focus on the use of injectable platelet-rich fibrin (I-PRF) as a regenerative tool with the potential to prompt tissue regeneration. In this regard, this systematic scoping review aimed to collect, map, and appraise the in vitro and in vivo studies regarding the role of I-PRF in or soft and hard tissue regeneration in relation to oral and maxillofacial structures. Methods: A systematic electronic search of Medline, Scopus, Web of Science, and Embase databases was performed from 2000 to December 2021 using a combination of keywords. All in vitro and in vivo studies, written in English and concerning the potential role of I-PRF in regenerative dentistry were considered. Results: In total, 18 in vitro studies, 5 animal studies, 6 case reports, and 31 clinical studies have evaluated the effect of I-PRF on oral and maxillofacial soft and hard tissue regeneration. The investigated studies verified the anti-inflammatory, anti-microbial efficacy and the positive effects of I-PRF application for wound, periodontal, bone, cartilage, and pulp regeneration, as well as acceleration in tooth movement during orthodontic treatment. Conclusions: Current literature approves the feasibility of I-PRF application as a promising regenerative adjunct to dental procedures.

Does kinesio taping reduce pain, swelling, and trismus after mandibular third molar surgery? A systematic review and meta-analysis.

The aim of this study is to provide an evidence-based conclusion regarding the effectiveness of kinesio taping (KT) in reducing postsurgical discomforts after mandibular third molar surgery and critically appraise the available literature. Eligible clinical trials evaluating patients older than 18 years who were treated with any type of KT compared to no taping in which pain, swelling, or trismus scores were reported were included. An electronic literature search was carried out in the following databases to identify relevant papers up to May 30, 2021: Medline, Cochrane Central Register of Controlled Trials, Web of Science, and Scopus. The risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials (RoB 2.0). The effect sizes were calculated using mean difference (MD) and standardized mean difference (SMD). The heterogeneity analysis was conducted using (I2) statistic at alpha = 0.10 (PROSPERO; CRD42021252670). Nine randomized clinical trials with 444 participants were included in the qualitative analysis and eight in the quantitative analysis. The results of the meta-analysis revealed a statistically significant reduction in pain and swelling scores before the 7th postoperative day. On the 7th postoperative day, no significant difference was observed between KT and control groups in terms of pain and swelling. Additionally, KT led to an increase in patients' maximum mouth opening of more than 3 mm in postoperative intervals. KT is effective in reducing postoperative pain within the first 48 h after surgery and improving mouth opening during all postoperative intervals with moderate to high certainty of evidence.

The adjunctive effect of autologous platelet concentrates on orthodontic tooth movement: A systematic review and meta-analysis of current randomized controlled trials.

OBJECTIVE: To evaluate the effectiveness of autologous platelet concentrates (APCs) as adjuncts on accelerating orthodontic tooth movement (OTM) of the human subjects undergoing orthodontic treatment and to critically appraise the available literature. METHODS AND MATERIALS: Five electronic databases (PubMed, Scopus, Web of Science, Embase, and Cochrane Central Register of Controlled Trials) were searched from 2000 up to May 2021 to retrieve eligible randomized controlled trials (RCTs) investigating patients who underwent orthodontic treatment that involved OTM of maxillary and mandibular incisors and canines. All the enrolled cases were treated with APCs and had no local or systemic interfering factors. The quality of the included studies was assessed using the modified JADAD scale. The effect sizes were assessed using mean difference (MD). The heterogeneity analysis was conducted using (I2) statistic at α=0.10. RESULTS: Finally, seven RCTs were included in the qualitative, and two RCTs were included in the quantitative analysis. The meta-analysis was performed regarding the effect of injectable platelet-rich fibrin (I-PRF) on the rate of canine tooth movement in millimeters at different intervals of the 1st, 2nd, and 3rd months. In the 1st month, I-PRF (WMD:0.12mm, CI95% -5.01 to 5.24, I2=90%) did not significantly affect OTM. In the 2nd month, I-PRF (WMD:0.66mm, CI95% 0.60 to 0.73, I2=10%) significantly increased the OTM. However, in the 3rd month, I-PRF did not significantly increase the OTM (WMD:0.54mm, CI95% -1.38 to 2.47, I2=67%). CONCLUSIONS: According to the low certainty of evidence about this topic, providing a definite conclusion is not possible. However, applying I-PRF seems to be efficient in accelerating the OTM of the canines. Further high-quality studies with larger sample sizes will be indispensable to validate this conclusion.

Efficacy of antimicrobial photodynamic therapy compared to nystatin therapy in reducing Candida colony count in patients with Candida-associated denture stomatitis: a systematic review and meta-analysis.

Purpose This meta-analysis assessed the efficacy of antimicrobial photodynamic therapy (aPDT) compared to conventional nystatin therapy (NYT) in reducing Candida colony count in patients with Candida-associated denture stomatitis (CADS) and critically appraised the available literature.Methods This meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) updated guidelines. A literature search was performed in four electronic databases to identify relevant articles up to 15 August 2021. Randomised controlled trials (RCTs) that assessed the efficacy of aPDT compared to NYT in reducing Candida colony count in patients with CADS were investigated. The weighted mean difference (MD) and 95% confidence interval were calculated. The I2 statistic was used to determine heterogeneity at the level of α = 0.10. The Cochrane risk of bias (RoB 2) tool was used to assess the risk of bias. Certainty of the evidence was determined using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) ranking system.Results Only three eligible RCTs with 141 participants were included in this systematic review and meta-analysis. Based on the pooled results, NYT compared to aPDT generally performed better in reducing Candida colony count (Log10 CFU/mL) in patients' palate and patients' denture. The included studies had a moderate risk of bias and the certainty of the evidence was low.Conclusion Although still inconclusive, based on the current evidence, aPDT may be effective in reducing Candida colony count and treating CADS. Nonetheless, it does not appear to be more effective than conventional NYT in this regard. According to the limited number of included studies, more well-designed RCTs with larger sample sizes and standardised methodology should be conducted to validate this conclusion.

Effectiveness of low-level laser therapy on recovery from neurosensory disturbance after sagittal split ramus osteotomy: a systematic review and meta-analysis.

BACKGROUND: Orthognathic surgery such as bilateral sagittal split ramus osteotomy (BSSRO) for the treatment of mandibular deformities is one of the most common procedures in maxillofacial operations that may lead to neurosensory disturbance. In this study, we aimed to evaluate the effectiveness of low-level laser therapy (LLLT) on augmenting recovery of neurosensory disturbance of inferior alveolar nerve (IAN) in patients who underwent BSSRO surgery. METHODS: A comprehensive literature search was conducted by two independent authors in PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Embase, and Google Scholar electronic databases. Besides, a manual search of all textbooks and relevant articles were conducted. Searches took place in August 2020 and were limited to published and peer-reviewed articles from 2000 to 2020. All analysis was performed using the comprehensive meta-analysis (CMA) and the STATA MP (version:16) software. The weighted mean difference (WMD) using the inverse variance method and the standard mean difference (SMD) was considered for continuous variables. RESULTS: Seventy-four papers were retrieved after removing duplicate studies and finally, eight studies were assessed for qualitative synthesis and five for meta-analysis. Totally, 94 patients were included in the meta-analysis. Based on the meta-analysis, it was shown that LLLT was not effective in a short interval (0 to 48 h) after surgery, but in a period of more than 1 month after surgery, the positive results of treatment can be observed strikingly. Also, LLLT side/group showed no significant difference in some aspects of neurosensory recovery such as thermal sensation compared to the placebo side/group. CONCLUSIONS: The meta-analysis of randomized controlled trials revealed that LLLT generally improves IAN sensory disturbance caused by BSSRO. Further high-quality clinical trials with longer follow-up periods and larger sample sizes are recommended.
