Prevalence and anatomy of radix entomolaris and paramolaris in mandibular molars - A CBCT study at North Western India

TL;DR

This study examines the occurrence and structure of extra roots in lower molars among the Punjab population using CBCT scans.

Contribution

The study provides new prevalence data and anatomical details of radix entomolaris and paramolaris in North Western India.

Findings

The overall prevalence of radix roots was 4.05%, with 2.9% for radix entomolaris and 1.1% for radix paramolaris.

Radix entomolaris was more common in first molars, while radix paramolaris was more common in second molars.

The average root length was 14.3 mm, and the mean curvature was 46.2°.

Abstract

The prevalence and anatomy of Radix Entomolaris and Radix Paramolaris in mandibular molars of Punjab Population using CBCT is of
interest. Among 271 scans reviewed, the overall prevalence of radix roots was 4.05%, with RE found in 2.9% and RP in 1.1% of cases. The
average root length was 14.3 mm and the mean curvature was 46.2°. RE was more frequently seen in first molars, while RP appeared
slightly more in second molars. These findings highlight the need for awareness of such anatomical variations to ensure better outcomes
in endodontic procedures.
