Various Root Canal Configurations Of The First And Second Mandibular Premolars In A South Indian Population

Aim: To evaluate the various root canal configurations of first and second mandibular premolars in a south Indian population. Background :The first and second mandibular premolar roots and canals may have a wide range of morphologies. Endodontic care of mandibular premolars is difficult due to their varying morphology. Differences in root canal anatomy have been attributed to nonsurgical root canal treatment failures and a high incidence of endodontic flare-ups.Hence, an in-depth examination of root canal configuration is needed to avoid endodontic obstacles. Materials and Methods: The current study is an institutional based retrospective study performed at Saveetha dental college,chennai.A total of 400 subjects who reported symptomatic apical periodontitis of mandibular premolars were chosen for the study in a total of 49,832 subjects screened for the data. All the case records and treatment records were obtained from the patient management software known as DIAS.The statistical analysis was performed using IBM SPSS ( Version - 26 ). Results: The results showed that the most common root canal configuration was Type I, followed by Type V in first premolar and Type II in second mandibular premolar. Chi square tests were performed between gender to prevalence of various canal configuration Statistical significance was set at p <0.05. A significant correlation was observed in the results. Conclusion: Within the limitations of the study, the majority of mandibular premolars have a single canal, the presence of two or three canals is not uncommon; thus, clinicians should always presume that these teeth have two or more canals when performing endodontic therapy.
