One hundred preclinical year dental students were examined. Oral hygiene status and gingival condition were determined using the Plaque Index score (Silness & Löe 1964) and the Gingival Index score systems (Löe & Silness 1963). The width of the attached gingiva and the depth of the gingival pockets were evaluated. The gingival recessions were recorded and their heights measured from the CEJ to the gingival margin. No significant correlation was found between oral hygiene and gingival recession, oral hygiene and width of attached gingival conditions and width of attached gingiva. Only a negative correlation (P less than 0.05) was found between the width of attached gingiva and the number of gingival recessions. No statistically significant differences were observed in oral hygiene status and gingival conditions among three groups of students (without, with one and with two or more recessions, respectively). The roles of toothbrushing trauma and "adequate" width of attached gingiva in the etiology of gingival recessions are questioned.
对100名临床前牙科专业学生进行了检查。使用菌斑指数评分系统（Silness和Löe，1964年）和牙龈指数评分系统（Löe和Silness，1963年）确定口腔卫生状况和牙龈状况。评估附着龈宽度和牙龈袋深度。记录牙龈退缩情况，并测量从牙釉质牙骨质界到牙龈边缘的高度。未发现口腔卫生与牙龈退缩、口腔卫生与附着龈宽度以及附着龈宽度之间存在显著相关性。仅发现附着龈宽度与牙龈退缩数量之间存在负相关（P小于0.05）。在三组学生（分别为无牙龈退缩、有一处牙龈退缩和有两处或更多处牙龈退缩）之间，未观察到口腔卫生状况和牙龈状况有统计学上的显著差异。刷牙创伤和附着龈“足够”宽度在牙龈退缩病因学中的作用受到质疑。
