The aim of the present investigation was to study thickness of masticatory mucosa and gingival width in subjects with different periodontal phenotypes.
Periodontal phenotypes were defined with the aid of cluster analysis of standardised parameters including mean gingival thickness and width as well as ratio of crown width to its length at maxillary canines, lateral and central incisors of 40 young adults with healthy periodontal conditions.
3 groupings could be observed. Clusters A1 and A2 comprised 75% of all subjects. They were characterised by thin gingiva and a slender tooth form. Clusters A1 and A2 were differentiated by gingival width. Cluster B comprised 11 subjects with relatively thick and wide gingiva and a quadratic tooth shape. In general, characteristics of the frontal sextant in the maxilla were also found in other parts of the dentition. Thus, mean thickness of masticatory mucosa as well as gingival width and crown form differed significantly among clusters. In addition, cluster B subjects had a significantly greater mean periodontal probing depth. Multiple linear regression analysis was employed to identify significant factors influencing palatal mucosal thickness. Women had considerably thinner palatal mucosa than men. Furthermore, cluster affiliation had a significant influence on thickness of palatal mucosa. Thickest tissue was found in the premolar region, whereas the mucosa over the root prominence of the first molar represented an anatomical barrier for graft harvesting.
Thickness of masticatory mucosa strongly depends on gender and the periodontal phenotype.
本研究旨在探讨不同牙周表型受试者咀嚼黏膜厚度和牙龈宽度。
借助聚类分析，对40名牙周健康的年轻成年人上颌尖牙、侧切牙和中切牙的标准化参数（包括平均牙龈厚度和宽度以及冠宽与冠长之比）进行分析，以确定牙周表型。
可观察到3种分组。A1组和A2组占所有受试者的75%。其特征为牙龈薄且牙形细长。A1组和A2组通过牙龈宽度区分。B组包括11名牙龈相对厚且宽、牙形呈方形的受试者。一般来说，上颌前部牙弓的特征在牙列其他部位也有发现。因此，咀嚼黏膜的平均厚度、牙龈宽度和牙冠形态在各组间存在显著差异。此外，B组受试者的平均牙周探诊深度显著更大。采用多元线性回归分析确定影响腭黏膜厚度的显著因素。女性的腭黏膜比男性薄得多。此外，分组对腭黏膜厚度有显著影响。最厚的组织位于前磨牙区，而第一磨牙牙根隆突上方的黏膜是移植取材的解剖学屏障。
咀嚼黏膜厚度强烈依赖于性别和牙周表型。
