摘要: Objective: To evaluate the clinical effect of fluoride releasing flowable resin used in treatment of early enamel caries of children compared with conventional sealant. Methods: Seventy-six patients, including fifty-two couples of permanent first molars and thirty couples of premolars were selected for this trial. Both sides of all the molars and premolars were diagnosed as early enamel caries based on International Caries Detection and Assessment System (ICDAS) dental caries diagnostic criteria. Using the contralateral control, the teeth were randomly divided into two groups. Molars/premolars in the expe-rimental group were sealed with a fluoride releasing flowable resin; the contralateral molars/premolars were sealed with a conventional fissure sealant as a control group. The retention rate and progress of caries were evaluated at the end of 3, 6, 12 and 24 months. Results: There was no fissure sealant loss or caries progression in both groups 3 and 6 months after sealing the premolars by fluoride releasing flowable resin or conventional fissure sealants. At the end of 12 and 24 months, only one case of fissure sealant loss was observed in conventional fissure sealant group. There was no statistical significance between the two premolar groups. In the first molar group, fluoride releasing flowable resin showed 100%, 98.08%, 90.38% and 88.46% complete retention at the end of 3, 6, 12 and 24 months, respectively. The conventional fissure sealant retention rates were 96.15%, 92.31%, 76.92% and 73.08% at the corresponding time points. The data at the end of 24 months showed that fluoride releasing flowable resin had significantly higher retention rate than the conventional fissure sealant group (P<0.05). The incidence of caries progression at the end of 6, 12 and 24 months were 1.92%, 5.77% and 7.69%, respectively, in the fluoride releasing flowable resin group. In the conventional fissure sealant group, the incidence was 5.77%, 19.23% and 25.00%, respectively. At the end of 12 and 24 months, more significant decrease of caries progress incidence was observed in the fluoride releasing flowable resin group than in the control group, and there was statistical difference between the two groups (P<0.05). Conclusion: Compared with conventional fissure sealant, using fluoride releasing flowable resin as a fissure sealant in children enamel caries of permanent molars can improve the sealant preservation rate and effectively prevent enamel caries progress.
