Abstract

Background: Rugae are the anatomical folds that are located on the anterior third of palate behind the incisive papillae. They are also known as "Plica palatine," and the study of these patterns is called palatoscopy. It can be used in various fields such as sex determination, orthodontics and forensic odontology. Objective: To investigate palatal rugae patterns in females and males and to evaluate the stability of these patterns in pre- and post-operative orthodontic cases. Materials and Methods: Fifty patients were selected for this study (25 males and 25 females). From the above sample, 10 males and 10 females had undergone orthodontic treatment and their casts were retrieved for sex determination analysis and stability of rugae patterns pre- and post-treatment. Results: Changes occur in bony structures during fixed orthodontic treatment but rugae patterns remain stable. Kappa stats and Chi square test were used to analyze agreement between the two evaluators, and 95% correct matches were achieved. Conclusion: Palatal rugae are unique to every individual and can be used as an indicator in forensic odontology.
