Abstract

The surface area and the longest diameter of gingival and palatal corneocytes and of superficial alveolar mucosa cells were assessed morphometrically. From a total of 92 subjects (46 males, 46 females) 5 to 75 years of age, cells of each class were collected by either the strip method or the imprint technique. The nuclear and cytoplasmic profiles and the diameter of about 30 cells per class and subject were drawn and scanned with a MOP-I system (Kontron, Zürich). Average data collected for 8 groups of males and females of increasing age demonstrated that with respect to the two parameters neither corneocytes nor exfoliating alveolar mucosa cells changed in size with increasing age, ther was no general difference in cell size between the sexes, and gingival corneocytes with retained nuclei were slightly larger than those without nuclei, particularly in males. These observations are in contrast to those reported for epidermal corneocytes.

摘要

采用形态测量法评估牙龈、腭部角质形成细胞以及浅表牙槽黏膜细胞的表面积和最长直径。在总共92名年龄在5至75岁的受试者(46名男性,46名女性)中,通过条带法或印记技术收集每类细胞。用MOP-I系统(康强电子公司,苏黎世)绘制并扫描每个受试者每类约30个细胞的细胞核和细胞质轮廓以及直径。对8组年龄递增的男性和女性收集的平均数据表明,就这两个参数而言,角质形成细胞和脱落的牙槽黏膜细胞的大小均不会随年龄增长而变化,两性之间细胞大小无总体差异,且保留细胞核的牙龈角质形成细胞略大于无细胞核的牙龈角质形成细胞,尤其是在男性中。这些观察结果与表皮角质形成细胞的相关报道相反。
