Objective To investigate the preventive effect of cavity and fissure sealing and resin filling on deciduous teeth caries. Methods A total of 100 children with deciduous tooth caries were selected as the subjects of the study. According to the random grouping method, they were divided into conventional group and experimental group, with 50 students in each group. The conventional group was treated with pit and fissure sealing, and the experimental group was treated with pit and fissure sealing and preventive resin filling. The retention rate of sealant, the incidence rate of dental caries, the mean level of dental caries, the dental health index and the satisfaction degree of preventive treatment were compared between the two groups at different time. Results There was no difference in sealant retention rate, caries incidence rate and mean caries level between the two groups 6 months after intervention (P > 0.05). At 12 and 18 months after intervention, the sealant retention rate in the experimental group was higher than that in the conventional group, and the incidence of dental caries and the mean level of dental caries were lower, P < 0.05. Compared with the conventional group, the experimental group had better dental health indicators and higher satisfaction with preventive treatment (P < 0.05). Conclusion Pit and fissure sealing and prophylactic resin filling can prevent deciduous caries and improve dental function.
