ABSTRACT

Background: The present study was conducted to assess the relationship with impacted mandibular third molar with mandibular canal with using panoramic radiographs and CBCT. Materials & Methods: The present study was conducted on 80 patients with impacted mandibular third molar. OPG and CBCT were done and assessment of relationship between mandibular canal with 3rd molar was performed. Results: Out of 80 patients, males were 35 and females were 45. Narrowing of canal (NC) in 8 males and 6 females, darkening of roots (DR) in 12 males and 20 females, diversion of canal (DC) in 7 males and 8 females, presence of cortication in 10 males and 8 females and interruption of white line (IWL) in 3 males and 5 females. PC was seen in 5 males and 6 females. The difference was significant (P< 0.05). Molar relation with IAC was class 0 (3), subtype 1A (12), subtype 1B (10), subtype 2A (5), subtype 2B (7), subtype 3A (10), subtype 3B (15), subtype 4A (2), subtype 4B (10), subtype 5A (1), subtype 5B (1), subtype 6A (1), subtype 6B (2) and class 7 (1). The difference was significant (P< 0.05). Conclusion: The relationship of impacted mandibular third molar with inferior alveolar canal using newer classification of CBCT images would definitely proven to be the boon for the surgeon.
