Abstract

Background and Objectives: Root anatomy of lower third molar (LTM) may have variable patterns. Root number, shape and curvature all affecting the process of surgery. To determine frequency of different root patterns of LTM.

Patients and methods: Retrospectively, a total of 196 orthopantomograms of department of radiology were evaluated for LTM root number and curvature of roots.

Results: two roots 173 (88.26%) one root 22 (11.74%). All single rooted teeth showed no curvature. Among two rooted teeth the study figured out that majority of roots not fused but converge 134 (77.45%), fused together 20 (11.5%), not fused but diverge 11 (≈ 6%), not fused with root curvature.

Conclusion: Majority of LTM have two or more roots, they are convergent or divergent. Root anatomy evaluation before surgery is mandatory.
