Subepithelial connective tissue grafting (SCTG) is a frequently used method in the field of periodontal plastic surgery. There are relatively few reports defining epithelial thickness criteria for palatal mucosal SCTG. The aim of this study was to histologically measure the epithelial thickness of the palatal mucosa in a sample of Korean patients, with the goal of minimizing epithelium-associated complications after root coverage procedures. A total of 30 Korean patients (12 males and 18 females) were enrolled in this study. To measure epithelial thicknesses, palatal mucosa adjacent to premolars and molars was obtained during procurement of SCTG. The effects of donor site, age and gender on the thickness of the epithelium were assessed and compared by histomorphometric analysis. The mean epithelial thickness of the palatal mucosa in our 30 patients was 430.63 μm, ranging from 113 to 823 μm. Epithelial thickness was not associated with donor site or age, but there were significant differences between genders, with males having much thicker palates than females.
黏膜下结缔组织移植术（SCTG）是牙周整形手术领域中常用的方法。目前关于腭黏膜 SCTG 的上皮厚度标准的相关报道较少。本研究的目的是通过对韩国患者样本进行组织学测量，以确定腭黏膜的上皮厚度，从而尽量减少根覆盖术后与上皮相关的并发症。本研究共纳入 30 例韩国患者（男 12 例，女 18 例）。为了测量上皮厚度，在获取 SCTG 时切取了前磨牙和磨牙附近的腭黏膜。通过组织形态计量学分析，评估并比较了供体部位、年龄和性别对上皮厚度的影响。在我们的 30 例患者中，腭黏膜的平均上皮厚度为 430.63μm，范围为 113μm 至 823μm。上皮厚度与供体部位或年龄无关，但在性别之间存在显著差异，男性的腭部比女性厚得多。
