Palatal rugae are asymmetric ridges of connective tissue located behind the incisive papilla over the anterior hard palate. They serve as stable superimposition landmarks to assess tooth movement in orthodontics and as identification aids in forensic odontology. However, the stability of palatal rugae remains controversial. This review aimed to describe the genetic, growth, and environmental factors that may influence the palatal rugae patterns. A broad search of PubMed and ScienceDirect databases was conducted. A total of 193 articles were identified, of which 73 met the selection criteria. Data were extracted into a table that presented the details of the study, sample description, and changes in the palatal rugae patterns.
There were conflicting results regarding sexual dimorphism and population characterization of the palatal rugae patterns. All rugae showed positional changes, increased lengths, and lower numbers, but no significant shape changes with growth. The lengths, numbers, and positions of the rugae were affected by orthodontic treatment, especially their lateral points, but their individual characteristics did not change.
The diversity in rugae patterns and their potential for sex discrimination among different populations showed differing results due to individual variations and the complex influence of genetic, growth, and environmental factors on their morphology.
腭皱襞是位于切牙乳头后方、前硬腭上的结缔组织不对称脊。它们是评估正畸牙齿移动的稳定叠加标志，也是法医牙科学中的识别辅助工具。然而，腭皱襞的稳定性仍存在争议。本综述旨在描述可能影响腭皱襞形态的遗传、生长和环境因素。对 PubMed 和 ScienceDirect 数据库进行了广泛搜索。共确定了 193 篇文章，其中 73 篇符合选择标准。将数据提取到一个表格中，该表格展示了研究的详细信息、样本描述以及腭皱襞形态的变化。
关于腭皱襞形态的性别二态性和人群特征存在相互矛盾的结果。所有的皱襞都表现出位置变化、长度增加和数量减少，但随着生长没有明显的形状变化。皱襞的长度、数量和位置受正畸治疗的影响，尤其是其侧点，但它们的个体特征没有变化。
由于个体差异以及遗传、生长和环境因素对其形态的复杂影响，腭皱襞形态的多样性及其在不同人群中进行性别区分的潜力存在不同的结果。
