Retrospective Analysis Of The Occurrence Of The Number Of Root Canals And Their Configuration In Mandibular Anteriors In South Indian Population

Abstract

Aim: The aim of the current study aimed to analyse the presence of a second canal in mandibular anterior teeth as identified by operators and to compare the configuration of the canal system among different mandibular anteriors

Materials and Methods: RCTs performed on mandibular anteriors as reported in DIAS (patient management software) were included. Duplicates were removed and the number of root canals as identified by the operator were assessed. Frequency distribution of nature of canals and Chi-square tests to check for association was done.

Results: 706 RCT treated mandibular anteriors were included.The prevalence of second canals was reported to be 6.8%. Type I Vertucci’s configuration is the most commonly found morphology (47.9%) followed by Type III and Type II. Mandibular lateral incisors are reported to have the greatest incidence of two canals. A positive association between operator’s experience and use of magnification with location of extra canals was found.

Conclusion: Within the limitations of the study, it can be concluded that the prevalence of two canals in mandibular anteriors is not uncommon, and Type I Vertucci’s classification is the most commonly reported type. In teeth with 2 canals, the most common reported configuration is Type III Vertucci’s classification.

Clinical Significance: The chances of a clinician coming across multiple canals is not uncustomary. Such clinical studies prepare the clinicians to search for extra canals to ensure greater success of endodontic therapies in the long-run.
