Thus, new imaging methods that can discriminate between sound dental tissues, demineralized enamel/dentin and composites with higher diagnostic performance are needed. Therefore, understanding the OCT accuracy to diagnosis restorative failure in laboratory studies is essential to estimate its clinical usefulness and employ resources in this area of research.

Methods and Materials: An electronic literature search was performed with MEDLINE via PubMed, Scopus, and Web of Science databases from January 2008 to June 2020. Two high-impact endodontic journals were also hand searched. The selection criteria were: Population; patients requiring endodontic treatment, Intervention and Comparison; endodontic instrumentation with reciprocating versus rotary systems, and Outcome; postoperative pain. We extrapolated all included research data and reported them as dichotomized ordinal variables to evaluate the incidence of pain and continuous variables to assess pain intensity. Standardized mean difference (SMD) was calculated with Inverse Variance method for pain intensity; the incidence of postoperative pain was calculated using relative risk (RR) with the Mantel-Haenszel method. Random-ef...

Abstract: This study evaluated the effect of carbamide peroxide (34%) and acidulated phosphate fluoride (1.23%) on two composite resins which received two different kinds of finishing: mechanical polishing and fiberglass matrix. 42 models made of resin, Filtek TM Z-250 - 3M/ESPE (grupo 1) and 42 made of Fill Magic® - Vigodent (group 2) were divided into two more groups: group 3 - 21 models were submitted to mechanical polishing wit...

This review followed the PRISMA statement and was registered at PROSPERO (CRD42018107918). Two independent reviewers searched the Lilacs, Cochrane Library, PubMed (Medline), Web of Science, Scopus, Scielo, and ScienceDirect for articles published until April 2021. The research question was, "Does occlusal reduction decrease postoperative pain in endodontically treated teeth?". Only randomized clinical trials were included. The RevMan 5 program was used for meta-analysis, calculating the relative risk (RR) and 95% confidence interval (CI) of the dichotomous outcome (presence or absence of pain). The search strategies retrieved 4114 studies. Twelve studies were included for qualitative analysis and nine for quantitative analysis. The meta-analysis results did not reveal ...

METHODS Prevalence studies and cohort studies, published in Latin American languages with no restrictions on publication dates, were considered. Two authors independently screened reference lists for eligible articles, assessed them for inclusion criteria, and extracted the data using a specific form. Twenty-six articles were selected, all prevalence studies. RESULTS The patients who used a helmet had a lower prevalence and severity of facial fractures, compared to patients who did not wear a helmet. There were no differences in the occurrence of lower third fractures between patients who used or did not wear a helmet at the time of the trauma; as well as in meta-analysis of occurrence and severity of facial trauma between helmet types (open or closed)....

MATERIALS AND METHODS A total of 138 class I and II restorations were performed and randomly divided into three groups (n = 46) with equal allocation: Filtek BF (FBF; 3M ESPE), Tetric EvoCeram BF (TBF; Ivoclar Vivadent), and control Filtek Z250 (Z250; 3M ESPE). The evaluations were performed using the USPHS and FDI criteria at baseline and after 12 and 36 months by a previously calibrated evaluator. The Friedman and Wilcoxon tests for paired data were used for statistical analysis (α = 0.05). RESULTS The DMFT index at baseline was 9.44, with 87% from the decayed component. After 36 months, 108 restorations (n = 36) were evaluated. Two failures were observed for TBF at marginal adaptation and recurrence of caries, resulting in a survival rate of 94.44% and an annual failure rate (AFR) of 1.26%. No equivalence was observed bet...

This review was registered at PROSPERO (registration number CRD42016053436). A search of the scientific literature was performed by two independent reviewers using the PubMed/MEDLINE, Embase, The Cochrane Library, and Web of Science databases from commencement until January 2018. The research question was “Do bulk-fill resin composites have a clinical performance comparable to conventional resin composites in posterior restorations?” Only studies evaluating class I and II direct restorations in permanent teeth with a follow-up period of at least 1 year were included. The RevMan 5 program was used for meta-analysis, calculating the relative risk (RR) and 95% confidence interval (CI) of the dichotomous outcome (restoration failure or succ...
