Incidence of Number of Roots in Maxillary Second Molars - A Cbct Analysis

The aim of the study is to find the incidence of the number of roots in maxillary second molars. In endodontic therapy, a comprehensive awareness of the root-canal anatomy is of great importance, and clinicians' failure to recognize an unusual canal morphology may lead to unsuccessful treatment. It is generally accepted that a serious explanation for the failure of passage therapy is an inability to localize and treat all of the canals of the basis canal system. In the present study, a total of 50 CBCT scan reports were collected from the Radiology department, Saveetha Dental College, Chennai, for evaluation. The CBCT scans were analysed for the number of roots and number of root canals present in maxillary second molars. The collected results were entered in Microsoft excel. Data analysis was done using SPSS software 20.0. The study results that the incidence of three roots are 83%, two roots are 10%, one root is 5% and four roots are 2 %. The incidence of three root canals is 86%, four root canals are 11% and two root canals are 3 %. Although the occurrence of maxillary second molar with one root or two roots isn't high, diagnosing these unusual cases at its early treatment stage is of significance for the success of endodontic treatment
