| Abstract | ||||
| Objective: To evaluate if there is an association between palatally displaced canines and sella turcica bridging, ponticulus posticus development. Material and methods: There were a total of 70 patients in the control group with normally erupted canines and 35 patients in the cases group with palatally displaced canines. Pre-treatment records (Lateral Cephalogram and CBCT) of all patients were used to assess sella turcica bridging and palatally displaced canines. Independent sample t tests were used to compare sella dimensions between patients and controls, whereas chi-square test was used to compare the association between sella bridging and palatally displaced canines. Results: The prevalence of Type I bridging was 25.7% in the cases group, compared to 54.3% in the control group. The control group contained 32 subjects (45.7%) with sella turcica bridging (types II and III according to Leonardi et al), while the cases group had 26 subjects (74.3%) with this anomaly (types II and III combined). In participants with canine impaction, the frequency of sella bridging was substantially higher than in controls (P=0.006). In PDC patients, the sagittal interclinoidal distance was observed to be significantly reduced (P=0.002). Ponticulus posticus was seen in 22% of the cases group and 12% of the controls group. (chi-square P=0.006) Conclusions: Palatally displaced canine patients showed a higher prevalence of sella turcica bridging. The length of sella is reduced in these patients. The development of ponticulus posticus is also associated with the occurrence of PDCs. | ||||
