Clinical effect of pit and fissure sealant used in combination with different etching adhesive and 3M-Z350 flowable resin on young permanent teeth

PURPOSE:To compare the effect of different etching adhesive and flowable resin in deep pits and fissures of young permanent molars sealant technique.METHODS: Children aged 6-8 years old were included in the study.The split mouth design was used.The first permanent molars were randomly assigned into 2 experimental groups:A and B.The teeth in group A were sealed with flowable resin and self-etching adhesive,while the teeth in group B were sealed with flowable resin and phosphate acid system.The children were followed up every year,and the sealants were observed and evaluated.SPSS13.0 software package was used for statistical analysis.RESULTS:After 1 year,2 and 3 years,the retention rate of group A was significantly lower than that of group B(P0.05),while group A had more caries than group B(P 0.05) except at 1-year.CONCLUSION: Self-etching adhesive and flowable resin doesn't have excellent clinical effect on caries prevention.
