The aim of the study is to estimate the prevalence of sella turcica anomalies on lateral cephalograms of individuals with malocclusion, so as to utilize it as a predictive indicator of malocclusion in adolescents. Lateral cephalograms of 224 subjects aged between 8-18 years with good visibility of cephalometric structures including sella turcica were assessed for the variants of malocclusion. The study group consisted of 133 cephalograms with abnormal sella turcica, while the control group consisted of 91 cephalograms without any abnormality. Cramer’s V test was applied to find out association of classes of malocclusion and Sellar anomalies, and chi-square test was applied to know the frequency of each sellar anomaly among the class-wise distribution within the subjects.
Males were more associated with sellar anomalies as compared to females. A significant association between skeletal classes of malocclusion and sella turcica with Cramer’s V value of 0.365 and significance of 0.001 was observed; so, it is clear that Class I malocclusion is associated with normal anatomy, while individuals with Class II and III are associated with sellar anomalies. An early predictive sign for prompt orthodontic intervention and correlating it with skeletal malocclusion can benefit both patients, as well as clinicians for interventional treatment.
