Abstract

Abstract: The sella turcica is one of the most important landmarks used by orthodontics in analysis of growth and treatment planning. Therefore, the purpose of this retrospective study was to detect whether there is a correlation between the sella turcica's linear dimensions and the vertical growth patterns of the jaws using CBCT in an Egyptian subpopulation. 144 CBCT scans of adult patients (68 males and 76 females) were taken from the archive of the Oral Radiology Department , Faculty of Dentistry, Suez Canal University. CBCT images were divided according to the vertical growth pattern of both maxilla and mandible into three groups; hypodivergent, normodivergent and hyperdivergent. The sella turcica diameter, length and depth were measured individually for each case. There were no statistically significant differences found between sella turcica's length and diameter measurements and vertical growth pattern of the jaws. While significant difference was found regarding the depth only between the three groups where the p-value was found to be 0.001. Conclusion: CBCT could be used as a highly accurate radiographic modality in assessing the linear dimensions of sella turcica .The sellar depth was the only linear measurement found to be affected by the vertical growth pattern of the jaws.
