In April of 1987, a study was begun in York County, Virginia to compare the effectiveness of traditional plaque control methods with the self- assessment of gingival bleeding as approaches to the prevention of gingivitis in teenagers. Four hundred ninety three ninth and tenth graders participated in baseline examinations for periodontal health, DMFS and gingival recession. Questionnaires regarding oral hygiene methods and professional care practices were completed. Following the examinations, subjects were randomly assigned by grade to either a positive control (plaque control) or test (self assessment of bleeding) group. The control group received a manual outlining procedures for the identification and control of plaque and the test group received a similar manual for the self-assessment and control of gingival bleeding. Small group and individual sessions for instruction in each procedure were held. In May, 1988 each participant was given the opportunity to have an oral prophylaxis and receive individual instruction to reinforce the appropriate group methods. Four interim examinations to assess periodontal health were conducted. In April 1989, the final examination assessed DMFS, gingival recession and periodontal status. Preliminary findings for the 356 subjects remaining after two years showed that the mean number of bleeding sites decreased dramatically in both the plaque control and self-assessment of gingival bleeding groups. Following further data analysis, final reports will be prepared.

1987年4月，弗吉尼亚州约克县开始了一项研究， 传统的牙菌斑控制方法的有效性， 牙龈出血的评估作为预防的方法 青少年牙龈炎 四百九十三第九和第十 分级者参加牙周健康的基线检查， 和牙龈萎缩。 关于口腔卫生方法的文件， 专业护理实践已完成。 在检查之后， 受试者按年级随机分配到阳性对照组和阴性对照组， （斑块控制）或测试（出血的自我评估）组。 对照组收到一份手册，概述了 识别和控制菌斑，试验组接受类似的 牙龈出血的自我评估和控制手册。 小 每项程序都有小组和个人授课。 1988年5月，每个参与者都有机会进行口头辩论。 预防和接受个人指导，以加强 适当的分组方法。 进行了四次中期检查以评估牙周健康。 在 1989年4月，期末考试评估DMFS，牙龈退缩和 牙周状况 剩余356名受试者的初步调查结果 两年后显示出血部位的平均数量减少 在牙菌斑控制和牙龈自我评估方面， 出血组。 在进一步的数据分析之后，将提交最终报告。 制备
