J Surg Pak Jan ;11(3):104-6.

Objective: To determine the position of canine in the maxillary and mandibular arches. Study Design: Cross-sectional analytical Setting: Orthodontic department, Karachi Medical & Dental College. Patients and Methods: The study was completed in 6 months. 200 patients were included in our study out of which females were138. The subjects were selected on non-probable, purposive technique. Inclusion criteria was patients not orthodontically treated previously, having symmetric arches of either sex between 14years and 25years having adult dentition. Patients exhibiting incisal or cuspal attrition, fractures of teeth or ectopically erupted teeth., having mixed dentition, with anomalies of tooth size e.g. microdontia, macrodontia, peg laterals etc. were excluded. Patients with anomalies of tooth number e.g. hyperdontia, hypodontia were also not included in this study. Position of canine in the arch were determined on the scanned image of the occlusal surface of the patients casts. Results: For both maxillary and mandibular arches, with-in the arch group showed significant values. In our study, the second most frequent position of canine in the maxillary arch was labial (15% of the total sample). In the mandibular arch the second most position of canine was also labial. (30% of the total sample). In the maxillary arch, 85% of the casts showed canine with-in the arch (P< .001). In the mandibular arch, 65% of the casts showed canine with-in the arch (P< .001). Conclusion: In our study we found the canine with-in the arch in significant number in both maxilla and mandible
