Abstract
INTRODUCTION: Growth, an expository variable aids the orthodontist in precise diagnosis and treatment planning. Variations in developmental pattern led to the evolution of malocclusion and dentofacial deformities. Developmental status of a patient can be evaluated by several methods but most of them failed to give a reliable estimate of skeletal maturity. AIM OF THE STUDY: To evaluate the correlation of frontal sinus morphology with cervical vertebrae stages as a skeletal maturity indicator. MATERIALS AND METHODS: A total of 180 lateral cephalograms of subjects aged between 8 and 16 years were included in the study. Based on the cervical maturation stages, the subjects were divided into 6 groups with 1:1 male to female ratio. The frontal sinus index and the cervical stages were evaluated on the same radiograph. Frontal sinus index was compared with different cervical stages by Kruskal-Wallis test and frontal sinus index values between adjacent cervical stages were compared for each sex by post hoc Dunnett T3 test. The correlation between the cervical stages and the sinus index were assessed by Kendall tau-b values. RESULTS: There was a significant linear increase and a good statistical correlation of the frontal sinus height and width at each cervical vertebral maturation stages. The index of frontal sinus increases statistically with the cervical vertebral maturation but had a weak correlation with the maturation stage. There was no significant relationship and no significant correlation of frontal sinus height, width and index with gender. CONCLUSION: Frontal sinus morphology cannot be used as a reliable sole indicator for the appraisal of skeletal maturity in patients.
