目的 观察和评价常规使用氟化泡沫预防乳牙龋齿的临床效果。 方法 实验对象为幼儿园幼儿。实验组采用2 分钟疗程常规使用方法。每年检查一次实验组和对照组乳牙患龋情况。 结果 临床实验表明,第一年检测,新患龋人数相对降低率为10 .52 % ,新患龋牙数相对降低率为8 .78 % ,新患龋牙面数相对降低率为 0 .45 % ;第二年检测,新患龋人数相对降低率为12 .90 % ,新患龋牙数相对降低率为12 .37 % ,新患龋牙面数相对降低率为8 .02 % 。 结论 在实验组和对照组相比每年常规使用氟化泡沫二次,新患龋牙面数和第一年新患龋牙数相对降低率小于10 % ,新患龋人数和第二年新患龋牙数相对降低率大于10 %
Objective To observe and evaluate the clinical effect of conventional fluorinated foam in preventing deciduous teeth of deciduous teeth. Methods Experimental subjects for kindergarten children. Experimental group using 2 minutes routine treatment. Check the experimental group and control group every year, deciduous teeth caries situation. Results The clinical trial showed that the relative reduction rate of new caries was 10.52% in the first year, the relative reduction rate of new caries was 8.78%, and the relative reduction rate of new caries was 0. 45%. In the second year, the relative reduction rate of new caries was 12.90%. The relative reduction rate of new caries was 12.37%. The relative reduction rate of new caries was 8.02%. Conclusions Compared with the routine use of fluorinated foam in the experimental group and the control group, the relative reduction rate of newly diagnosed dental caries and the number of newly diagnosed carious teeth in the first year is less than 10%. The number of new caries and the number of new cases in the second year The relative reduction rate of dental caries is more than 10%
