Preferred Reporting Items for Epidemiologic Cross-sectional Studies on Root and Root Canal Anatomy Using Cone-beam Computed Tomographic Technology: A Systematized Assessment

摘要: Abstract Introduction The purpose of this study was to perform a quality assessment and provide scientific-based checklist for prevalence studies on root canal anatomy by appraising the methodological in vivo using cone-beam computed tomographic (CBCT) imaging as tool. Methods A systematic literature conducted, 211 were selected submitted evaluation. Data grouped into categories such journal impact factor, open access availability, language, origin, publisher, sample size, CBCT settings. Interrater agreement calculated applying Holsti method Cohen kappa. Kruskal-Wallis test Pearson correlation coefficient undertaken assess different variables (α = 0.05). Results included (N 211) reported data 247,616 teeth from 41 countries. maxillary first molar most studied tooth (n 69) second mesiobuccal investigated anatomic feature. highest scores associated with high-impact journals (r 0.482, P Conclusions Although small improvement in global observed over years, only less than half correctly addressed participant recruitment frame had an adequate size or provided sufficient proposed highlights pertinent points guide researchers throughout experimental design implementation epidemiological cross-sectional nature.
