To evaluate the effectiveness of two pit and fissure sealants (PFS) in reducing the incidence of dental caries in schoolchildren.
A randomized split-mouth experimental design was used in a sample of 140 subjects assigned to two groups. The sealants used were Clinpro©3M and BeautiSealant©Shofu placed in first permanent molars (FPMs). Each sealant was compared to molars in the controls to determine effectiveness over a period of 6 months. The study had a 12.9% loss to follow-up. No statistically significant differences (p>0.05) were observed for sex, age, baseline dmft, or type of sealants. Nonparametric tests were used for statistical analysis.
Average dmft index at baseline was 4.10±3.16. Lower incidence of caries was observed in FPMs with pit and fissure sealants (p<0.01), regardless of the type used. When sealants remained intact there was a lower caries incidence compared to sealants partially or completely missing - but differences were only significant for FPM 16. Caries incidence was higher for BeautiSealant sealed teeth than for Clinpro's, but only statistically significant in FPMs 16, 36 and 46 (p< 0.05). Caries incidence was higher in those cases with a higher baseline dmft but it only reached statistical significance in FPMs 26 and 36. Relative risks for dental caries were lower in sealed teeth (p<0.01).
Pit and fissures sealants are an effective preventive treatment to reduce caries during a 6-month follow-up in schoolchildren 6 to 8 years of age, regardless of the type of sealant used. The sealant brand that showed greater effectiveness in terms of prevention and retention was Clinpro©3M.
评估两种窝沟封闭剂（PFS）在降低学龄儿童龋齿发病率方面的有效性。
采用随机分组口内对照实验设计，选取140名受试者分为两组。所用的封闭剂为3M公司的Clinpro©和松风公司的BeautiSealant©，分别应用于第一恒磨牙（FPM）。将每颗使用封闭剂的磨牙与对照组磨牙进行比较，以确定6个月期间的有效性。该研究有12.9%的失访率。在性别、年龄、基线龋失补牙数（dmft）或封闭剂类型方面未观察到统计学显著差异（p>0.05）。采用非参数检验进行统计分析。
基线时平均dmft指数为4.10±3.16。无论使用何种类型的窝沟封闭剂，在使用窝沟封闭剂的第一恒磨牙中观察到龋齿发病率较低（p<0.01）。当封闭剂保持完整时，与部分或完全缺失的封闭剂相比，龋齿发病率较低——但差异仅在第一恒磨牙16上显著。BeautiSealant封闭的牙齿龋齿发病率高于Clinpro封闭的牙齿，但仅在第一恒磨牙16、36和46上具有统计学显著性（p<0.05）。基线dmft较高的病例中龋齿发病率较高，但仅在第一恒磨牙26和36上达到统计学显著性。封闭牙齿患龋齿的相对风险较低（p<0.01）。
窝沟封闭剂是一种有效的预防性治疗方法，可在6至8岁学龄儿童6个月的随访期间降低龋齿发病率，无论使用何种类型的封闭剂。在预防和保留方面显示出更高有效性的封闭剂品牌是3M公司的Clinpro©。
