Assessment Of Prevalence & Length Of The Anterior Loop Of Inferior Alveolar Nerve & Mandibular Incisive Canal Using Cone Beam Computed Tomography Images Among Indian Population: A Retrospective Cross-Sectional Radiographic Study

Abstract

• Objective: To assess the prevalence & measure the length of anterior loop & mandibular incisive canal of the inferior alveolar nerve using Cone- Beam Computed Tomography (CBCT).


• Materials and Methods: A total of 250 CBCT scans of patients between the age 15 to 60 years with equal distribution among males and females were randomly selected and evaluated retrospectively.


• Results: The prevalence of anterior loop was 10.4 % & the prevalence of mandibular incisive (MIC) canal was 75.2 %. The mean length of MIC on right side was 4.743 ± 2.1226 mm & on left side was 4.431 ± 2.0613 mm. The mean length of anterior loop on the right side was 3.1206 ± 0.99440 mm & on the left side was 3.2264 ± 1.00606 mm.


• Conclusion: Plotting the incisive nerve canal & anterior loop will help oral radiologists, to plan safely and negotiate the interforaminal region. This will additionally enable surgeons to avoid postoperative neurosensory complications.
