Abstract
Aim: Aim of this study is to evaluate the palatal bone thickness on lateral cephalogram and its comparison with CBCT scans in different growth patterns and to find the gender differences if exists in palatal bone thickness at various measuring sites. Materials and Method: In this study 90 subjects with age ranging from 16-25 years visiting the Department of Orthodontics were chosen. Subjects were categorized into average, horizontal and vertical growth pattern groups according to Jarabaks ratio. They were further divided into male and female group to determine gender dimorphism if any. Palatal bone height was measured antero-posteriorly at a distance of 3, 6, 9, 12, 15, 18, 21 and 24 mm posterior to incisive canal both on lateral cephalogram and CBCT. Results: This study showed the palatal bone thicknessonlateral cephalograms is less when compared to CBCT at all the distances from incisive canal (p<0.0001). The horizontal growth pattern showed highest palatal bone thickness at all the intervals followed by average and vertical and a statistically significant difference was found between the three groups (p<0.0001). Independent t test reported higher amount of bone thickness in males as compared to females on both lateral cephalogram and CBCT (p<0.05). Conclusion: Lateral Cephalogram showed less bone thickness when compared to CBCT. Horizontal growth pattern showed highest amount of bone thickness followed by average and vertical growth pattern.
