Assessment of post obturation radiographs for canal configuration in maxillary second premolars - A retrospective study

Abstract

Aim: The aim of this study was to assess the root canal configuration of maxillary second premolars using post obturation ra-diographs. Materials and Methods: Details of endodontic procedures done in maxillary second premolar teeth June 2019 to March 2020 which constituted 746 procedures were collected retrospectively. Post obturation radiographs of these teeth were assessed for canal configuration based on Vertucci’s classification. Association between gender and tooth number with Vertucci’s Classification on root canal configuration was analyzed using Chi-square test. Results: The most common variation was Vertucci’s Type II (29.49%), followed by Type I (29.09%), Type IV (28.95%), Type V (8.04%), Type III (2.41%) and Type VI (2.01%). There was no significant difference seen between gender and prevalence of variation in maxillary second premolars based on Vertucci’s classification of root canal configuration (p>0.05), although males showed a slightly higher predilection for Type II configuration while females for Type I configuration. A significant difference was observed in the relation between tooth number and prevalence of variation in maxillary second premolars based on Vertucci’s classification of root canal configuration (p<0.05). Conclusion: Maxillary second premolars most commonly showed Vertucci’s Type I, II, and IV configurations. Type V and Type VI had the least occurrence. Type VII and Type VIII configurations were not observed. Males showed a slightly higher predilection for Type II configuration while females for Type I configuration.
