The aim of this study was to analyze the association between sella turcica bridging (STB) and palatally impacted canine and to investigate the correlation between the angular measurements of palatally impacted canine and STB using cone beam computed tomography (CBCT).
The impaction group included 36 subjects (16.97 ± 6.00 years) who had at least one palatally impacted canine and the control group consisted of 36 subjects (16.89 ± 3.52 years) who had normally erupted canines without any dental anomalies. Sella turcica and dental measurements were obtained from reconstructed CBCT images using OnDemand3D 1.0software. Sella turcica dimensions were compared between two groups, and the STB ratio, the proportion of interclinoid distance to diameter of sella turcica, were compared between the impacted and non-impacted sides. Correlation coefficients were calculated between the angular measurements of palatally impacted canine and STB ratio.
In the impaction group, interclinoid distance and STB ratio were significantly smaller than those of the control group (p < 0.001). The distribution of STB type II, partial calcification of intercliniod ligaments, was significantly higher in the impaction group than in the control group (p < 0.05). However, there was no significant difference of STB between the impacted and non-impacted sides (p > 0.05) in the unilateral impaction group. Further, STB ratio was negatively correlated with the mesiodistal angulation and the buccolingual inclination of the palatally impacted canine (p < 0.05).
The STB was more frequently found in patients with palatally impacted canine, and the degree of STB was significantly associated with the angular measurements of impacted canine.
