Root Canal Morphology

Abstract

Purpose: Primary molars tend to exhibit more variations in canal morphology compared to that newlineof permanent molars. There is still a lacuna of adequate studies evaluating the morphology of newlineprimary maxillary molars in the literature. This systematic review aimed to analyze the root newlinecanal morphology of primary maxillary molars using different diagnostic aids in different ethnic newlinepopulation Materials and Methods: An exhaustive search was undertaken to identify published newlineliterature related to the root anatomy morphology of the primary maxillary molars. Using a newlinecombination of key words search was done up to April 2020 in Medline/PubMed, The Cochrane newlineCentral Register of Clinical Trials, SIGLE and Science Direct. The included data consist of type newlineof population, number of teeth per study, number of root canals, canal length and type of root newlinecanal configuration. Results: A total of 13 studies (951 primary maxillary molars) which met the newlineinclusion criteria were taken up for the systematic review. Maxillary molars (1st and 2nd) showed newlinemore predominance for two roots variant. In maxillary first molar the mean root length ranges newlinefrom 7.9mm 8.1mm and in second molar it ranges from 7.2mm-8.5mm. Type I canal newlinemorphology is the most common variant in both the molars. Results: Root Canal morphology newlineshows considerable variations with the diagnostic aid used and in different ethnic populations. newlineAlthough micro ct is the most advanced imaging modalities currently available, the practical newlineapplications are yet to be determined. newline
