Evaluation of the efficacy of enameloplasty sealant technique combined with fluoresced releasing flowable resin in the treatment of pit and fissure enamel caries
Objective To evaluate the clinical efficacy of enameloplasty sealant technique (EST) com-bined with fluoride releasing flowable resin in pit and fissure enamel caries.Methods A total of 247 young permanent molars diagnosed as early pit and fissure enamel caries from 125 children aged 6-12 years in Uru-mqi Stomatological Hospital were selected as the study subjects.They were divided into four groups:group A (conventional cleaning of pit and fissure+conventional sealant) 32 cases,62 teeth;group B (conventional cleaning of pit and fissure+fluorine releasing flowable resin) 29 cases,62 teeth;group C (EST+conven-tional sealant) 33 cases,62 teeth;group D (EST+fluorine releasing flowable resin) 31 cases,61 teeth.After 6 and 18 months of follow-up,the retention rate of sealants and rate of caries-free were compared among the various groups.Results After 6 months of follow-up,the retention rates of sealant in groups A,B,C and D were 75.00％,76.67％,93.33％ and 95.00％ respectively,and which after 18 months of follow-up were 45.76％,41.38％,71.93％ and 94.92％ respectively,and the differences were statistically significant (P<0.05).The results of further multiple comparisons showed that there were statistically significant differences in the retention rate of sealant between group A and group C,group B and group D after 6 and 18 months of follow-up (P<0.0083),moreover there was statistically significant difference in the retention rate of sealant between group C and group D after 18 months of follow-up (P<0.0083).After 18 months of follow-up,the rates of caries-free in groups A,B,C and D were 66.10％,63.79％,94.74％ and 98.31％,respectively.The re-sults of further multiple comparisons showed that the rates of caries-free between group A and group C,group B and group D were statistically significantly different (P<0.0083).Conclusion The retention rate of seal-ant and long-term caries prevention effect of adopting the EST in the treatment of pit and fissure enamel caries are superior to the conventional sealant technique.EST combining with fluorine releasing flowable resin could further increase the retention rate of sealant.
