Abstract：Objective To observe the clinical effect of pit and fissure sealant with different clinical acid etching tech-nique. Methods Totally 240 permanent first molars in children aged 6-8 years old were randomly divided into three groups. Group A:self-etching adhesive;Group B:EST with self-etching adhesive;Group C:phosphoric acid. All the chil-dren were followed up and reexamined after 3,6 and 12 months. Results The retention rates of pit and fissure sealant and the prevalence rates of caries in three groups had no significant difference after 3 and 6 months(P>0.05). At 12th month,the retention rate of pit and fissure sealant in self-etching adhesive group was statistically lower than than in the other groups(P<0.05),and the prevalence rate of caries was statistically higher than that in the others(P<0.05). But the other two groups had no significant difference in the retention rate of pit and fissure sealant and the prevalence rate of caries(P>0.05). Conclusion The clinical effect of pit and fissure sealant with self-etching adhesive is worse than with phosphoric acid,but it can be improved by combining enameloplasty sealant technique. The effect of phosphoric ac-id and EST combination self-etching adhesive are the same.
