Periodontal and implant therapies frequently require soft tissue augmentation for optimal outcomes. As the hard palate serves as the primary donor site, this study evaluated palatal masticatory mucosa thickness variations in a Saudi population of the Eastern Province using cone-beam computed tomography (CBCT) at a teaching dental hospital, providing site-specific data for clinical applications. A retrospective cross-sectional analysis of 215 CBCT scans from systemically healthy, non-smoking adults (>18 years) was conducted at the University Dental Hospital. Measurements were taken at 12 standardized sites (3 mm, 6 mm, and 9 mm from the cementoenamel junction) across maxillary canines, premolars, and first molars. Statistical analysis included Friedman's test and t-tests. Significant site variations were observed, with the second premolar region showing greatest thickness (3.48 ± 0.80 mm at 9 mm) and the first molar region the lowest (1.88 ± 0.63 mm at 3 mm) ( < 0.001). Mucosal thickness generally increased coronally to apically ( < 0.001). Age >35 years correlated with significantly thicker mucosa ( < 0.05), while no statistically significant gender-based differences were observed for all sites ( > 0.05). CBCT provides reliable, non-invasive assessment of palatal mucosa thickness. These findings offer region-specific data for consideration in periodontal and implant procedures involving soft tissue grafting.
牙周治疗和种植治疗常常需要进行软组织增量术以获得最佳疗效。由于硬腭是主要的供区，本研究在一家教学型牙科医院，使用锥形束计算机断层扫描（CBCT）评估了沙特东部省份人群的腭部咀嚼黏膜厚度变化，为临床应用提供了特定部位的数据。在大学牙科医院对215例来自全身健康、不吸烟的成年人（>18岁）的CBCT扫描进行了回顾性横断面分析。在上颌尖牙、前磨牙和第一磨牙的12个标准化部位（距牙骨质釉质界3 mm、6 mm和9 mm）进行测量。统计分析包括弗里德曼检验和t检验。观察到显著的部位差异，第二前磨牙区域显示出最厚的厚度（9 mm处为3.48±0.80 mm），第一磨牙区域最薄（3 mm处为1.88±0.63 mm）（<0.001）。黏膜厚度通常从冠部到根部逐渐增加（<0.001）。年龄>35岁与黏膜明显增厚相关（<0.05），而所有部位均未观察到基于性别的统计学显著差异（>0.05）。CBCT提供了对腭黏膜厚度可靠的、非侵入性的评估。这些发现为涉及软组织移植的牙周和种植手术提供了特定区域的数据以供参考。
