Pak Oral Dental J Jan ;36(2):323-6.

The complexity of the root canal system is the major challenge for any dentist undertaking root canal treatment. It is therefore considered important to be familiar with variations in root or canal anatomy. This was a cross-sectional survey of 60 patients with symptomatic irreversible pulpitis in mandibular third molars in patients of both gender of age 25-40 years. After access cavity opening, all the canals were located radiographically with files placed inside the canals. In this study, sixty patients were included. Out of sixty patients, 45 (75%) patients contained three root canals, eleven (18.3%) patients contained two root canals, three (5%) patients contain four root canals while only one (1.7%) patient had one root canal. This in vivo study of number of canals has provided the practitioner with an understanding of the clinical implication of mandibular third molars.
