Introduction: Rugae patterns are significant markers for analyzing anteroposterior changes in adolescence, and forensic investigations. Aim: The purpose of this study was to ascertain the gender-wise predisposition of rugae patterns and to analyze anteroposterior alterations along with any developmental changes in palatal depth. Materials and Methods: One hundred pre-treatment study cast models were obtained from the archives of the Department of Orthodontics, M.M. CDSR, Mullana. Parameters employed were: Division of medial palatal region into "a": Distance between incisive papilla length and anterior limit of the anteriormost rugae; "b": Distance between incisive papilla and most posterior rugae limits; measurement of Lateral rugae dimensions and palatal depth. Statistical analysis: Mean ± S.D. values were obtained and ′P′ values calculated. Results: Comparison of "a" and "b" showed a significant difference in the P values between the age-groups 12-13 years and >14 years. Rugae patterns with separate origins showed a predisposition for female gender. Conclusion: A significant change in the anteroposterior medial rugae dimensions was seen in adolescent age groups alongside no variation in palate depth. Hence, it can be concluded that differential growth potential is present in the premaxilla and can cause shift in medial palatal dimensions without altering the rugae patterns and palatal depth.Downloads
