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.
To investigate palatal rugae patterns in females and males and to evaluate the stability of these patterns in pre- and post-operative orthodontic cases.
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.
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.
Palatal rugae are unique to every individual and can be used as an indicator in forensic odontology.
腭皱襞是位于切牙乳头后方硬腭前三分之一处的解剖学褶皱。它们也被称为“腭襞”，对这些形态的研究称为腭纹检查。它可用于性别鉴定、正畸学和法医牙科学等各个领域。
研究女性和男性的腭皱襞形态，并评估正畸手术前后这些形态的稳定性。
本研究选取了50名患者（25名男性和25名女性）。从上述样本中，10名男性和10名女性接受了正畸治疗，并获取了他们的模型用于性别鉴定分析以及治疗前后腭皱襞形态的稳定性分析。
在固定正畸治疗期间，骨结构会发生变化，但腭皱襞形态保持稳定。使用卡方统计和卡方检验分析两位评估者之间的一致性，达到了95%的正确匹配率。
腭皱襞因人而异，可作为法医牙科学中的一项指标。
