This survey attempted to determine the status of oral cleanliness and gingival health in 150 dental students and 101 faculty members in a dental school. Without advance notice, plaque deposits were scored, using the Plaque Index System, and gingival health was determined using the criteria of the Gingival Index System. The 1st-year students had the poorest hygiene and gingival health. An improvement (P less than 0.01) was noted in the 2nd-year students who were still not in clinical training but had completed a course in preventive dentistry including oral hygiene techniques. Further improvement (P less than 0.05) was found in students participating in the clinical courses (3rd and 4th years). However, some deterioration of both hygiene and gingival status occurred in the senior 5th year. Among the faculty, the best oral hygiene and gingival state were found in members of departments in which clinical work centered around patient motivation toward prevention and tooth conservation. The scores for plaque and gingivitis were worse in the departments of oral surgery, dental materials, orthodontics and the basic science departments. Almost all departments and every class showed a few individuals with very poor oral hygiene. It is suggested that regular patient contact influences the personal attitude toward oral hygiene, and that professional activity and emphasis on different aspects of the curriculum may be reflected in the attitude of health professionals toward oral health.
本次调查旨在确定一所牙科学院150名牙科学生和101名教职员工的口腔清洁状况和牙龈健康状况。在没有提前通知的情况下，使用菌斑指数系统对菌斑沉积情况进行评分，并使用牙龈指数系统的标准来确定牙龈健康状况。一年级学生的口腔卫生和牙龈健康状况最差。在尚未接受临床培训但已完成包括口腔卫生技术在内的预防牙科课程的二年级学生中，情况有所改善（P<0.01）。参与临床课程（三年级和四年级）的学生有进一步改善（P<0.05）。然而，在五年级高年级时，口腔卫生和牙龈状况都出现了一些恶化。在教职员工中，临床工作以患者预防和牙齿保护积极性为中心的科室成员口腔卫生和牙龈状况最佳。口腔外科、牙科材料、正畸科和基础科学科室的菌斑和牙龈炎评分较差。几乎所有科室和每个班级都有一些口腔卫生非常差的个体。研究表明，定期与患者接触会影响个人对口腔卫生的态度，并且课程不同方面的专业活动和重点可能会反映在卫生专业人员对口腔健康的态度上。
