To treat mucogingival problems palatal masticatory mucosa is used as a donor material. This study aimed to determine the thickness of donor palatal mucosa and associations of age and gender in Indian subjects aged 14 to 60 years by direct clinical technique.
Forty systemically and periodontally healthy Indian subjects (20 males; 20 females; age range of 14 to 60 years) enrolled in this study. Under local anesthesia bone sounding technique was performed at 15 defined and predetermined points. The Wilcoxon test was used to determine the difference in mucosal thickness between the age groups and between genders. Significance of the difference between individuals of different body mass index (BMI) was assessed by independent t-test.
With mean thickness of 2.0 to 3.7 mm, the younger age group demonstrated significantly thinner donor mucosa (mean 2.8±0.3 mm) than the older age group (mean 3.1±0.3 mm). Within the same age group though statistically not significant; males had thicker mucosa than females. From the canine to second premolar areas and in the sites furthest from the gingival margin mucosa thickness increased. When correlated with subject's BMI, in all probed sites males demonstrated significantly a thicker mucosa than females. Within each group subjects with high BMI demonstrated thicker donor mucosa.
Current study showed that in both adult and young individuals, premolar and canine areas can be the right site for harvesting donor tissue. Even in young subjects subepithelial connective tissue (CT) graft can be harvested in adequate volume. Donor tissue thickness can be influenced by factors like genetics and race, which need to be further evaluated.
Premolar and canine areas serve as appropriate choice to harvest palatal masticatory mucosa. Even in young patients the volume of donor tissue available is sufficient enough to consider the subepithelial CT graft procedure. Donor tissue thickness can be influenced by factors like genetics and race, which need to be further evaluated.
使用腭部咀嚼黏膜作为供体材料治疗黏膜牙龈问题。本研究旨在通过直接临床技术确定14至60岁印度受试者的供体腭黏膜厚度以及年龄和性别的相关性。
40名全身及牙周健康的印度受试者（20名男性；20名女性；年龄范围为14至60岁）纳入本研究。在局部麻醉下，于15个明确且预先确定的点进行骨探测技术。采用Wilcoxon检验确定年龄组之间以及性别之间黏膜厚度的差异。通过独立t检验评估不同体重指数（BMI）个体之间差异的显著性。
较年轻年龄组的供体黏膜平均厚度为2.0至3.7毫米，明显比年长年龄组（平均3.1±0.3毫米）更薄（平均2.8±0.3毫米）。在同一年龄组内，尽管无统计学意义，但男性的黏膜比女性更厚。从尖牙到第二前磨牙区域以及离牙龈边缘最远的部位，黏膜厚度增加。当与受试者的BMI相关联时，在所有探测部位，男性的黏膜明显比女性更厚。在每组中，BMI高的受试者供体黏膜更厚。
当前研究表明，在成年人和年轻人中，前磨牙和尖牙区域都可能是获取供体组织的合适部位。即使在年轻受试者中，也可以获取足够量的上皮下结缔组织（CT）移植物。供体组织厚度可能受遗传和种族等因素影响，这需要进一步评估。
