The caries experience and the plaque and gingival conditions of 14-year-old children participating in fortnightly fluoride (0.2 % NaF) mouth rinsing (88 subjects) were compared with observations in children performing supervised toothbrushing with a fluoride (0.5 % NaF) solution 4-5 times per year (n = 90). Most of the children, 84 and 90% respectively, had participated in these programs for the previous 6 years. Caries was assessed only on radiographs. The mean number of decayed surfaces was 5.8 (s.d. = 4.1, n = 88) and 5.4 (s.d. = 4.1, n = 90). The mean numbers of decayed and filled surfaces were 19.3 +/- 9.2 and 27.9 +/- 10.2 for subjects with rinsing or brushing. This significant difference could not be ascribed to sex, social class, years of residence in the towns, number of dentists performing the previous treatments, toothbrushing habits, use of fluorides at home, or amount of plaque. All children had gingivitis. There were no differences in the mean number of Plaque Index score 2 or the number of Gingival Index score 2 between the children with the different preventive programs. The girls' oral hygiene was better than the boys', but the gingival conditions were the same. Sex, social class, and toothbrushing techniques tended to have a slight influence on the amount of plaque.
将参与每两周一次使用氟化物（0.2%氟化钠）漱口水的14岁儿童（88名受试者）的龋齿经历、牙菌斑和牙龈状况，与每年4 - 5次使用氟化物（0.5%氟化钠）溶液进行监督刷牙的儿童（n = 90）的观察结果进行了比较。大多数儿童，分别为84%和90%，在过去6年中参与了这些项目。仅通过X光片评估龋齿情况。龋面均数分别为5.8（标准差 = 4.1，n = 88）和5.4（标准差 = 4.1，n = 90）。进行漱口水治疗或刷牙治疗的受试者，龋面与补牙面均数分别为19.3±9.2和27.9±10.2。这种显著差异不能归因于性别、社会阶层、在城镇居住的年限、之前进行治疗的牙医数量、刷牙习惯、在家中使用氟化物的情况或牙菌斑量。所有儿童均患有牙龈炎。在不同预防项目的儿童中，菌斑指数评分为2的均数或牙龈指数评分为2的数量没有差异。女孩的口腔卫生状况优于男孩，但牙龈状况相同。性别、社会阶层和刷牙技巧对牙菌斑量往往有轻微影响。
