Examination of the Relationship Between Sella Turcica and Impacted Maxillary Canine Teeth: A Retrospective Study

Objectives: In the present study, we aimed to compare the morphological shape and linear dimensions of the sella turcica (ST) between individuals with and without impacted maxillary canines (IMC). Materials and Methods: Cone-beam computed tomography scans of 120 individuals with IMC were obtained, retrospectively. A control group of 40 individuals without IMC were included in the study from the same archive. The study group was divided into three subgroups: group I (n=40), right IMC; group II (n=44), left IMC; and group III (n=36), bilateral IMC. The shape and the linear dimensions of the ST were evaluated in all groups. Data were analyzed using an independent sample t-test and the chi-square test. The significance level was assigned as p<0.05. Results: The linear dimensions ‒length, depth, and diameter‒ of the ST in the control group were significantly different from those in group I (p=0.050, p=0.001, and p=0.018, respectively), group II (p=0.040, p=0.048, and p=0.006, respectively), and group III (p=0.014, p=0.039, and p=0.007, respectively). In addition, there were no statistically significant associations among ST types in the control and study groups. Conclusions: The length, depth, and diameter of the ST were greater in the control group than in the individuals with unilateral or bilateral IMC. Also, no relationship was found between the morphological shapes of the ST in individuals with and without IMC.
