Aims: To perceive an interrelation between sella turcica bridging and maxillary canine impaction among impaction patients. Methods: Lateral cephalometric and Panoramic Radiographs of 50 subjects with impacted canines (25 buccal and 25 palatal) ware collected from Orthodontic clinics. The control group consisted of 25 orthodontic patients without a history of impaction. The size of Sella turcica (length, depth and diameter) was calculated and the bridging was gauged among the study groups. Results: Results were evaluated using independent sample t-test and chi-square test on SPSS software (P<0.05). The percentage of partial and complete calcification of sella among patients with palatal impaction were (4%) and (80%), respectively. Whereas, with buccal impaction were (0%) and (48%), respectively. The odds of having partial and complete bridging among the patients with impaction canines was 3 times higher than the control group (odds ratio, 3.210; 95% CI, 1.66-6.17). Gender wise comparison showed significantly reduced mean sagittal interclinoidal distance among females as compared to the male subjects (p=0.001). Conclusions: The occurrence of sella turcica bridge in patients with canine impaction is increased.Early detection of Sella Turcica bridge during the development phasemay alert clinicians to likely canine impaction in advanced life.
