研究目的:

通过临床实验比较氟保护漆与口腔健康教育在替牙期儿童龋病防治中的临床效果,评估氟保护漆的防龋效能,并通过对比氟保护漆干预前后儿童口腔唾液PH、氟离子浓度、口腔优势菌变化趋势等指标探讨氟化物的防龋机制;筛查出可以在替牙期儿童中大规模推广的防龋措施,为改善我省儿童的口腔健康状况提供应用基础研究的科学依据。  

Objectives of Study:

Clinical trials were conducted to compare the clinical effects of fluoride protectors and oral health education on the prevention and treatment of caries in children during dental replacement period, to evaluate the anti-caries efficacy of fluoride protectors, and to explore the anti-caries mechanism of fluoride by comparing the PH of saliva, fluoride ion concentration and the trend of oral dominant bacteria before and after the intervention of fluoride protectors. To screen out the preventive measures which can be widely promoted in children during dental replacement period, and provide scientific basis for the application of basic research to improve the oral health status of children in our province.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用随机法,信封发放班级随机号。一个班级42人,文件袋中分别有6个密封的小信封,包含实验组A、对照组B、对照组C,3个组,每组信封为2个,由学生班主任随机抽取小信封,决定班级学生入组。其中领取到A为涂氟和口腔健康教育实验组,领到B为涂氟对照组,领到C为口腔健康教育对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

In this study, the random method was adopted, and the envelopes were issued with random class numbers. There are 42 students in A class. There are 6 sealed small envelopes in the file bag, including 3 groups of experimental group A, control group B and control group C. Each group has 2 envel

盲法:

检查者、记录者和被检查者均不知道分组情况,(根据干预者随机抽取信封,决定干预措施。由老师分配检查记录组进入班级,进行抽取到的干预措施)

Blinding:

The examiner, the recorder, and the examined were not aware of the grouping. (Envelopes were randomly selected according to the intervenor and intervention measures were determined. The teacher assigns the inspection record group to enter the class to carry out the extracted intervention measures)
