摘　　要：目的分析釉质成形窝沟封闭术(EST)结合释氟流动树脂在窝沟釉质龋中的临床疗效。方法选取就诊于乌鲁木齐市口腔医院的6~12岁患儿125例,以诊断为早期窝沟釉质龋的247颗年轻恒磨牙作为研究对象,分为4组:A组(常规清洁窝沟+常规封闭剂)32例、62颗,B组(常规清洁窝沟+释氟流动树脂)29例、62颗,C组(EST+常规封闭剂)33例、62颗,D组(EST+释氟流动树脂)31例、61颗。随访6、18个月后,比较各组封闭剂保留率与无龋率。结果随访6个月A、B、C、D组的封闭剂保留率分别为75.00%、76.67%、93.33%和95.00%,随访18个月分别为45.76%、41.38%、71.93%和94.92%,差异均有统计学意义(P<0.05);进一步多重比较显示,随访6、18个月A组与C组、B组与D组的封闭剂保留率均有明显差异(P<0.0083),且随访18个月C组与D组的封闭剂保留率有明显差异(P<0.0083)。随访18个月,A、B、C、D组的无龋率分别为66.10%、63.79%、94.74%和98.31%;进一步多重比较显示,A组与C组、B组与D组的无龋率均有明显差异(P<0.0083)。结论在窝沟釉质龋的治疗中,采用EST的封闭剂保留率和远期防龋效果都明显优于常规窝沟封闭术,结合释氟流动树脂可进一步提高封闭剂保留率。Objective To evaluate the clinical efficacy of enameloplasty sealant technique(EST)combined 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 Urumqi 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+conventional 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 results 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 sealant 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 f
