BACKGROUND The objective was to compare the palatal bone thickness (PBT) and palatal bone density (PBD) in the anterior, middle, and posterior part of the palate in males and females. METHODS This retrospective study reviewed cone beam computed tomography scans of 359 patients. The scans were divided into 99 growing males, 105 growing females, 74 non-growing males, and 81 non-growing females. The measurements of PBT and PBD were made in between the canine and first premolar, the first premolar and second premolar, the second premolar and first molar, and the first molar and second molar. The measurements were made in the center of the palate and 4 mm away from the center. ANOVA was used to analyze the PBT and PBD in different areas between four different groups. RESULTS The PBT was lower (P <  0.0001) as we moved from the anterior to the posterior palate. The PBT was more (P <  0.001) in the center of the palate than 4 mm away from the center, except in between the canine and first premolar. The growing male and non-growing male had higher (P <  0.0001) PBT than the growing female and non-growing female in between the canine and first premolar and the first premolar and second premolar both in the center and 4 mm away from it. The PBD was higher (P <  0.05) in between the canine and first premolar area at the center of the palate and between the second premolar and first molar 4 mm away from the center in all the experimental groups. CONCLUSIONS There exists a definite gender and growth variation in the PBT and PBD in different parts of the palate. Palatal bone thickness between the males and females revealed that the males had significantly higher PBT than the females.

微型种植体的pa骨厚度和密度的性别和生长变化。

背景技术目的是比较男性和女性the的前，中和后部的pa骨厚度（PBT）和pa骨密度（PBD）。方法这项回顾性研究回顾了359例患者的锥形束计算机断层扫描。扫描分为99个生长中的雄性，105个生长中的雌性，74个不生长的雄性和81个不生长的雌性。在犬和第一前磨牙，第一前磨牙和第二前磨牙，第二前磨牙和第一磨牙以及第一磨牙和第二磨牙之间进行PBT和PBD的测量。在the的中心和距中心4 mm处进行测量。方差分析用于分析四个不同组之间不同区域的PBT和PBD。结果PBT较低（P <0。0001），当我们从前颚移到后颚时。除了在犬齿和第一前磨牙之间，上颚中央的PBT距离中央的距离大于4 mm（P <0.001）。在犬和第一前磨牙之间以及距中心4 mm处的第一前磨牙和第一前磨牙和第二前磨牙之间，成年雄性和非成年雄性的PBT高于（P <0.0001）PBT。在所有实验组中，上颚中央的犬和第一前磨牙区域之间以及距中心4 mm的第二前磨牙和第一磨牙之间的PBD较高（P <0.05）。结论在上颚的不同部位，PBT和PBD存在一定的性别和生长差异。
