This study was conducted to identify the morphometric features of the hard palate and to test the reliability of using palatal morphology in sex determination. Three hundred maxillary casts were collected from dental clinics in north Jordan. The age and gender of the patient and the serial number for each cast were recorded. The age range was 6 to 50 years old. A caliper was used to perform the following measurements: the length, width, and depth of the hard palate. In addition, the size, shape, and position of the incisive papilla were also determined. All measurements were done by a trained examiner who was able to perform the measurements in a reproducible manner. Statistical analysis showed that the mean palatal length, width, and depth, and size of dental papilla in both groups were the highest in males. The full logistic regression model including all the three predictors (length, width, and depth) indicated that the three parameters were significantly correlated with gender in the adult group. However, in the child group, only width and length were significantly (=0.001, > 0.042 respectively) correlated with gender. Regarding the shape and size of the incisive papilla, they were significantly different between males and females in both adult ( > 0.03) and child (=0.001) groups. These findings might be potentially relevant to anthropological studies aiming at individual and/or sex identification. Moreover, the results might have clinical value in prosthodontics, especially in fabricating complete maxillary dentures for edentulous patients.
本研究旨在确定硬腭的形态特征，并测试利用腭部形态进行性别判定的可靠性。从约旦北部的牙科诊所收集了300个上颌模型。记录了患者的年龄、性别以及每个模型的序列号。年龄范围为6至50岁。使用卡尺进行以下测量：硬腭的长度、宽度和深度。此外，还确定了切牙乳头的大小、形状和位置。所有测量均由一名经过培训的检查者进行，该检查者能够以可重复的方式进行测量。统计分析表明，两组中男性的腭平均长度、宽度、深度以及牙乳头大小均最高。包含所有三个预测变量（长度、宽度和深度）的完整逻辑回归模型表明，这三个参数在成年组中与性别显著相关。然而，在儿童组中，只有宽度和长度与性别显著相关（分别为=0.001，>0.042）。关于切牙乳头的形状和大小，在成年组（>0.03）和儿童组（=0.001）中，男性和女性之间均存在显著差异。这些发现可能与旨在进行个体和/或性别识别的人类学研究潜在相关。此外，这些结果可能在口腔修复学中具有临床价值，特别是在为无牙患者制作全口上颌义齿方面。
