本研究旨在测量腭粘膜上皮和固有层的厚度，阐明腭大动脉的位置，为上皮下结缔组织移植提供解剖学基础。从犬齿远中区到第一磨牙远中区取32个上颌标本，石蜡包埋，苏木精-伊红染色。在这些标本上的三个位置测量腭粘膜上皮和固有层的厚度，从牙槽嵴下3 mm开始，间隔3 mm。利用图像处理软件评价腭大动脉的位置。平均上皮厚度显着减少后牙，它是0.41，0.36，0.32，和0.30毫米，在犬齿，第一前磨牙，第二前磨牙，和第一磨牙远侧区，分别。犬远端的固有层明显较厚，分别为1.36、1.08、1.09和1.05 mm。从牙槽嵴到腭大动脉的平均长度向后磨牙方向增加，分别为7.76、9.21、10.93和11.28 mm。从腭粘膜表面到腭大动脉的平均深度从犬齿远端到第一前磨牙远端逐渐减小，但朝向后磨牙再次增加，分别为3.97、3.09、3.58和5.50 mm。腭粘膜固有层和腭大动脉的详细组织学评估有望为上皮下结缔组织移植提供有用的解剖学指导。
This study aimed to measure the thickness of the epithelium and lamina propria of the palatal mucosa and to elucidate the location of the greater palatine artery to provide the anatomical basis for subepithelial connective tissue grafting. Thirty-two maxillary specimens, taken from the canine distal area to the first molar distal area, were embedded in paraffin and stained with hematoxylin-eosin. The thickness of the epithelium and lamina propria of the palatal mucosa was measured at three positions on these specimens, starting from 3 mm below the alveolar crest and in 3-mm intervals. The location of the greater palatine artery was evaluated by using image-processing software. The mean epithelial thickness decreased significantly in the posterior teeth; it was 0.41, 0.36, 0.32, and 0.30 mm in the canine, first premolar, second premolar, and first molar distal areas, respectively. The lamina propria was significantly thicker in the canine distal; it was 1.36, 1.08, 1.09, and 1.05 mm, respectively. The mean length from the alveolar crest to the greater palatine artery increased toward the posterior molar; it was 7.76, 9.21, 10.93, and 11.28 mm, respectively. The mean depth from the surface of the palatal mucosa to the greater palatine artery decreased from the canine distal to the first premolar distal but increased again toward the posterior molar; it was 3.97, 3.09, 3.58, and 5.50 mm, respectively. Detailed histological assessments of the lamina propria of the palatal mucosa and the greater palatine artery are expected to provide useful anatomical guidelines for subepithelial connective tissue grafting.
