The oral hygiene levels and behaviour in pre-clinical and final-year dental students attending Birmingham University 1977 were investigated. Gingival inflammation, bacterial plaque and calculus accumulations were clinically recorded. Tooth cleaning habits were assessed by a questionnaire. Oral hygiene habits differed between the two groups and an improvement in oral hygiene levels was evident in the final-year students. Statistically significant differences (P less than 0.05) were found between the plaque index scores of the pre-clinical and final-year students, and for the gingival and calculus index scores of the male students. Thus in this investigation it was possible to show that improvement in oral hygiene does occur between the pre-clinical and final year of the undergraduate course.
对1977年就读于伯明翰大学的临床前和最后一年牙科专业学生的口腔卫生水平和行为进行了调查。临床记录了牙龈炎症、牙菌斑和牙结石的堆积情况。通过问卷调查评估牙齿清洁习惯。两组学生的口腔卫生习惯有所不同，最后一年的学生口腔卫生水平有明显改善。临床前和最后一年学生的菌斑指数得分之间，以及男生的牙龈和牙结石指数得分之间存在统计学上的显著差异（P小于0.05）。因此，在这项调查中，可以表明本科课程的临床前和最后一年之间口腔卫生确实有所改善。
