Abstract：Objective To evaluate the clinical applications of Fluor protector combined with self-etching adhesive system in the technique of pit and fissure sealant on young permanent tooth.Methods 1200 first permanent molar from 300 children aged 6 to 8 years old were studied,and the split-mouth design was used in the study.The first permanent molars were randomly selected and divided into two groups.The teeth of experimental group (n=300) were used with Fluor protector and self-etching adhesive,while the teeth in control group (n=300) were sealed with phosphate acid system.The cases were observed after 6,12,18 months after the operation.The caries rate,retention rate were observed and the operating time was compared between experimental group and control group.Results 6 months after operation,there was no significant difference in retention rates between the two groups (P>0.05),and the retention rate of experimental group were statistically higher than that in control group after 12,18 months (P <0.05).The caries rate in experimental group was not significantly different from that of control group after 6 months (P>0.05),while the caries rate in experimental group was statistically lower than that in control group after 12,18 months (P<0.05).The time of operating a tooth in experimental group was (129±9.3)s,which was significantly shorter than (243±8.6)s in control group (P<0.05).Conclusion Fluor protector combined with self-etching adhesive of Pit and Fissure sealant technique could improve the retention rate and reduce the incidence of caries,and save the operating time.It is suggested that the Fluor protector combined with self-etching adhesive of Pit and Fissure sealant technique on young permanent teeth should be applied to clinical practice.
