【摘要】：目的:探讨同时应用窝沟封闭和涂氟预防干预乳磨牙预防龋齿的效果,为学龄前儿童乳磨牙龋齿的预防提供新的干预措施。方法:通过Cariostat法对150名学龄前儿童乳磨牙进行龋蚀活跃性试验,将其分为龋活跃高危人群和低危人群,检查其乳磨牙患龋情况,计算龋均。随机抽取30名龋活跃高危人群儿童做为实验组1,30名龋活跃低危人群儿童做实验组2,应用窝沟封闭和多乐氟护齿剂同时对乳磨牙进行龋病预防干预;同时抽取30名龋活跃低危人群做对照组应用多乐氟护齿剂对乳磨牙进行龋病预防干预,于干预后6、12、18个月计算龋病发病率。结果:龋活跃高危人群和低危人群的患龋率分别为68.75%、28.6%,两组比较有显著性差异(P0.05)。干预后6个月时,实验组1、实验组2、对照组龋病发病率分别为12.3%、11.6%、13.1%,三组比较无显著性差异(P0.05);12个月时,龋病发病率分别为12.4%、11.8%、23.2%,实验组1、实验组2比较无显著性差异(P0.05),实验组1、实验组2均显著低于对照组,有显著性差异(P0.05);18个月时,龋病发病率分别为13.2%、12.9%、29.3%,实验组1、实验组2均显著低于对照组,有显著性差异(P0.05),但实验组1、实验组2比较无显著性差异(P0.05)。结论:同时应用窝沟封闭和涂氟对乳磨牙可以有效防龋,降低学龄前儿童的龋发病率。
[Abstract]:Objective: to explore the effect of preventing primary molars from dental caries by the combination of fissure sealing and fluorination, so as to provide a new intervention for the prevention of dental caries in primary molars of preschool children. Methods: the caries activity of primary molars of 150 preschool children was tested by Cariostat method. The teeth were divided into active high risk group and low risk group. The caries of primary molars were examined and the mean caries were calculated. Thirty children with active and high risk caries were randomly selected as experimental group (group 1) and 30 children with low risk of caries activity (group 2). At the same time, 30 active and low risk persons of caries were selected as the control group. The dental caries prevention intervention was carried out in primary molars with Dorafur dental preservatives. The incidence of caries was calculated at 612,18 months after the intervention. Results: the prevalence of caries in active high risk group and low risk group was 68. 75% and 28. 6%, respectively. There was significant difference between the two groups (P0.05). At 6 months after intervention, the incidence of caries in experimental group 1, experimental group 2, control group was 12.311.6 and 13.1respectively, there was no significant difference among the three groups (P0.05); at 12 months, the incidence of caries in the control group was 12.3and 11.6g, respectively (P0.05). The incidence of caries was 12.4 / 11.8g / 23.2 respectively. There was no significant difference between experimental group 1 and experimental group 2 (P0.05). Experimental group 1 and experimental group 2 were significantly lower than that of control group (P0.05); at 18 months, the incidence of caries in experimental group 1 was significantly lower than that in control group (P0.05). The incidence of caries was 13.2and 12.9R 29.3.The experimental group 1 and the experimental group 2 were significantly lower than the control group (P0.05), but there was no significant difference between the experimental group 1 and the experimental group 2 (P0.05). Conclusion: combined use of sealant and fluorine in primary molars can effectively prevent caries and reduce the incidence of caries in preschool children.
