Abstract：Objective To investigate the preventive and therapeutic effects of fissure caries sealing with light -cure fluid resin sealant on dental caries in children .Methods One hundred and twenty children (aged 6 ~10 years) with dental caries who were treated in our hospital from May 2013 to June 2014 were divided into trial group ( n =60) and control group ( n =60) according to random number table .The patients in trial group were treated by fissure caries sealing with light -cure fluid resin sealant,however,the patients in control group were treated by fissure caries sealing with visible light sealant .The preventive and therapeutic effects were observed and compared between two groups after 2-year follow-up survey.Results For non-dental caries,the complete retention rate and partial retention rate of sealant in the first year and second year in trial group were significantly higher than those in control group ( P <0.05),moreover, the complete expulsion rate in the second year in trial group was significantly lower than that in control group ( P <0.05).For early dental caries,the complete retention rate and partial retention rate of sealant in the first year and second year in trial group were significantly higher than those in control group ( P <0.05), moreover, the complete expulsion rate in the second year in trial group was significantly lower than that in control group ( P <0.05).For non-dental caries and early dental caries , caries prevalence rates in the first year and second year in trial group were lower than those in control group ,but there were no significant differences between two groups ( P >0.05).Conclusion The fissure caries sealing with light-cure fluid resin sealant has better stability ,moreover, the preventive and therapeutic effects need to be observed further .
