Root canal configurationof permanent maxillary first premolars in Cuddalore district, TamilNadu

Dental caries with pulpal involvement is a painful condition. In order to eliminate pain, pulp should be extirpated completely, although due to different configuration it remains difficult. This study aims to understand the various types of root canal configuration of maxillary first premolars in Cuddalore district, Tamilnadu based on the independent epidemiological studies. In order to understand the pattern of root canals, a set of 150 orthodontic extracted teeth was collected and its root canal configuration was studied using clearing method (Sharaddha Gupta, 2015). Then with the help of dye its root canal configuration was made visible and studied. According to Vertucci’s classification 1984 among the sample, single root where seen in 82.74%, double root where seen in 16.1% and three root where seen in 1.16% of sample. In single rooted teeth type IV is the most common type of root canal configuration seen in 38.04% of sample followed by type II in 21.24%. In double rooted tooth buccal root shows 6.3% followed by type III, and palatal root shows 7.5% of type I followed by type III, 2% . In triple rooted teeth 1.16% of type I in mesiobuccal root, 1.16% type VI in distobuccal root and 1.16% of type I were seen in palatal root. From the results type IV root canal configuration is the most common type configuration among the permanent maxillary first premolars in Cuddalore district, Tamil Nadu.
