Palatal rugae have been related with specific racial groups and are said to be useful in sex discrimination. This work aimed to characterize the palatal rugae patterns in a Portuguese population. Fifty plaster casts were examined for first and third rugae shape evaluation; shape, frequency, and association with sex were studied. In females, the most prevalent first rugae were the straight type on the right and the curve type on the left; in males, the straight type was the most prevalent on both sides. The most frequent third rugae type was sinuous on both sides, in both sexes. No significant sexual dimorphism in rugae shape was found (p > 0.05). When comparing these results with those from other investigations, it was clear that a particular rugae pattern could be established for different ethnic groups. However, the small sample size justifies further work in larger samples to validate these findings.
腭皱襞与特定种族群体有关，据说在性别歧视方面很有用。这项工作旨在描述葡萄牙人群中的腭皱襞模式。检查了50个石膏模型以评估第一和第三皱襞的形状；研究了形状、频率以及与性别的关联。在女性中，最常见的第一皱襞右侧是直线型，左侧是曲线型；在男性中，两侧最常见的都是直线型。在两性中，最常见的第三皱襞类型两侧都是蜿蜒型。未发现皱襞形状有显著的性别差异（p>0.05）。将这些结果与其他研究结果进行比较时，很明显可以为不同种族群体建立特定的皱襞模式。然而，样本量较小，因此有必要对更大的样本进行进一步研究以验证这些发现。
