Background and Objectives: The present study was designed to evaluate, the accurate relationship of the impacted third molar to the mandibular canal using cone beam computed tomography and its distance from cortical plates with its variation in relation to age, gender, side and angulation.
Materials and Methods: Three thirty four samples of cone beam computed tomography were identified. They were segregated according to different criterias say age, gender, side and angulation. The distance from the impacted tooth to the centre of mandibular third molar was measured. Also the distance between buccal and lingual cortical plates to the centre of the canal was measured. All the measurements were made with 3D CS software. Their variations with different criterias was identified.
Results: Statistical analysis was performed by using Karl Pearson correlation coefficient tests. The canal was most closely placed in case of females compared to males with respect to impacted tooth. Also the distance between the canal and tooth was less on the left side compared to the right side. There was no variation of the canal with age. But for angulation the distance was found to be more with horizontal and mesio angular impactions
Conclusion: The results of the present study shows that cone beam computed tomography is the best diagnostic tool to identify and locate the inferior alveolar canal in the mandible. The inferior alveolar canal has got a specific pattern of distribution which varies with side, age gender and angulations of impaction.
