Abstract

The current study assessed the frequency of different sella shapes that are encountered in orthodontic patients and found the association between sella shapes and patient parameters. A cross-sectional study was done in Altamash Institute of Dental Medicine, Karachi. All patients with skeletal class I, II or III with or without hypodontia were included in the study. Sella shapes were traced on lateral cephalograms. Frequency and percentage for the different sella shapes were calculated. The data was stratified as per sociodemographic characteristics, hypodontia, and skeletal class. 240 individuals with a mean age ± SD of 17.33 ± 4.1 years were enrolled in the study. Sella turcica bridging was present in 42 (17.5%). The occurrence of irregularity of the posterior part of sella was significantly correlated with the younger age group (p=0.035). Oblique anterior wall was found in 9 (52.9%) skeletal class I, 7 (41.1%) in class II, while 1 (5.8%) in class III. However, the difference was statistically insignificant (p=0.456). Out of the 15 patients with hypodontia 9 had normal sella, one had double contour of the floor, three had sella turcica bridge, and two had pyramidal shape of dorsum sellae. Our research demonstrated the significance of various shapes of sella turcica and its impact on the developmental process of teeth, albeit it failed to find an association with hypodontia. Thus, future studies should be carried out with a large sample of patients having hypodontia.
