| 目的：评估窝沟封闭对预防第一磨牙窝沟龋的2 年临床疗效。方法：选择贵阳市花溪区200 名7-9 岁经家长同意并签署窝沟
封闭知情同意书的学生为实验组，进行第一磨牙窝沟封闭；因家长不同意而未进行窝沟封闭的200 名同龄学生为对照组，两年内
复查两组的龋病发病率和封闭剂的保留情况。结果：实验组窝沟封闭后第一年、第二年第一磨牙龋病的发生率分别为1.50 %和
1.01 %，而对照组分别为4.00 %和6.57 %，第二年实验组的第一磨牙龋病发病率显著低于对照组，差异有统计学意义(P<0.05)。实
验组第一年、第二年的封闭剂完全保留率分别是85.5 %和80.4 %。结论：窝沟封闭作为一项健康干预措施，能有效降低学生的龋
病发病率。 |

| Objective:To evaluate the 2-year clinical efficacy of pit and fissure sealing in the prevention of pit and fissure caries
of the first permanent molars.Methods:200 students aged between 7-9 from Huaxi district, Guiyang, whose parents agreed to the
prevention and signed informed consent were selected as the experimental group and were given fissure sealing on first molars. Another
200 students whose parents disagreed were selected as control group. The clinical effect were observed between two groups after 1 and 2
years’fissure sealing.Results:In the following 1 year and 2 years, the caries incidence of the first molars of the treatment group were
1.50 % and 1.01 %, while the incidence of the control group were 4.00 % and 6.57 %, respectively. The caries incidence of the first
molars of the treatment group was statistically lower than that of the control group at the 2-year point (P<0.05). The complete sealant
retention rates of treatment group were repectively 85.5 % and 80.4 % in the following 1 and 2 years.Conclusion:As a health
intervention, the pit and fissure sealing could effectively reduce the incidence of caries in the students. |
