Abstract: PURPOSE: To investigate the effect of pit and fissure sealant combined with fluorine protective paint on prevention of children caries aged 5-8 years old. METHODS: Convenience sampling method was used to select 120 children who received oral health care in the First Affiliated Hospital of Zhejiang University and Hangzhou Dental Hospital from January 2014 to January 2017. They were grouped by random number table method: the control group (60 cases, 109 teeth) underwent pit and fissure sealant, and the experimental group (60 cases, 112 teeth) underwent pit and fissure sealant combined with fluorine protective paint. The patients were followed up for 2 years to compare the incident of dental caries. SPSS20.0 software package was used to analyze the data. RESULTS: The incidence of dental caries in the experiment group (2.68%) was significantly lower than that in the control group (10.09%) (P<0.05).The incidence of adjacent caries in the experiment group (1.79%) was significantly lower than that in the control group (9.17%) (P<0.05). At 1 and 2 years after sealing, the shedding rate(0.00%, 3.33%) of the sealant in the experiment group was significantly lower than that in the control group (10.00%, 15.00%)(P<0.05).The mean caries of the experiment group was significantly lower than that of the control group(P<0.05). CONCLUSIONS: The effect of combined pit and fissure sealant and fluoride protective paint on the prevention of dental caries in children aged 5-8 years old is ideal, which can reduce the incidence of dental caries and adjacent caries, reduce the mean caries, and keep the sealant intact. It is worthy of clinical promotion.
