Abstract

Abstract: Objective:To investigate the relevance of sella bridges and palatal impacted canine by comparing the size of sella turcica on patients with palatal impacted canines and normal canines. Methods:One hundred and three cases with palatal impacted canines were selected as experimental group, while 103 cases with normal canines were selected as control group. The length, depth and diameter of sella turcica were measured. Based on the calcification of sella turcica, cases were divided into type I, II and III. Results:Significant differences were found in the length and diameter between two groups. In the experimental group, the depth of sella turcica in male was larger than female, besides, there was no difference in the length and diameter between genders. However, there was no difference in the size of sella turcica between genders in the control group. The part and total calcification of sella turcica in the experimental group were 41.75% and 15.53%, which showed no significant difference between genders; while the part and total calcification of sella turcica in the control group were 8.73% and 4.85%. The incidence of sella turcica in the control group was 8.52 times of the experimental group. Conclusion:Length and diameter of sella turcica in the experiment group were larger, when compared to the control group. The incidence of sella bridges in the experimental group significantly increased, which showed no significant difference between genders.
