A Comparative Retrospective Analysis on Choice of Taper and Preparation Sizes among the Postgraduate Students in Mandibular Molars with and without Periapical Pathosis

Abstract

Preparation of the root canal system is recognised as being one of the most important stages in root canal
treatment. Cleaning and shaping is the crucial phase that eliminates infection. It involves removal of vital
and necrotic tissues from the root canal system along with root dentin. The aim of the present study is
retrospective analysis on choice of taper and proportion sizes among the postgraduate students in mandibular
molar with and without periapical pathosis. It is a single centred retrospective study, data was collected after
reviewing 86000 records of the patients between June 2019 and March 2020.Tapers used in the preparation
of the root canal system for mandibular molars have been assessed. In this study we observed that significant
association between taper of preparation and periapical pathosis (p<0.05). Within the limitations of the
study, 6% taper has been used for the teeth with periapical pathosis. 4% and 6% taper has been used in teeth
without periapical pathosis.
