 ABSTRACT

Objective: To evaluate the relative position of mandibular third molar with inferior alveolar nerve using cone beam computed tomography.

Study Design: Descriptive Cross-sectional study.

Place and Duration: Department of Oral Biology, Rehman College of Dentistry, Peshawar from 1stDecember 2016 to 30th April 2019.

Methodology: Cone beam computed tomography scans of 140 patients were evaluated and relative position  of inferior alveolar nerve  and mandibular 3rd molar was categorized into Buccal, Lingual, inferior and inter radicular positions. Direct contact or no contact was documented between mandibular third molars and inferior alveolar nerve and type of contact was stratified on nerve positions.

Results: Among 47.1% of cone beam computerized scans, Inferior alveolar nerve was present buccal to the mandibular 3rd molar with 27% having direct contact. 17.1% scans had Inferior alveolar nerve present lingual to the mandibular third molar with 41.6% having direct contact. Inferior alveolar nerve in 27.1% of scans was placed inferior to the mandibular 3rd molar with 57.8% having direct contact. In the remaining 8.6% of scans, Inferior alveolar nerve were present in the interradicular position with 100 percent having direct contact. P- value of buccal and interradicular position was found to be significant(p<0.05)

Conclusion: Cone Beam Computed Tomography is a precise tool for the preoperative assessment of patients undergoing the extraction of mandibular third molar.
