摘　　要：目的 比较树脂型窝沟封闭剂与树脂加强型玻璃离子结合不同粘接系统应用于乳磨牙窝沟封闭的操作时长、接受度及封闭效果,为口腔医疗资源匮乏地区的儿童提供更适宜的口腔医疗保健措施。方法 将符合条件的第2乳磨牙随机分为3组:树脂型窝沟封闭剂+全酸蚀组(SO组,对照组),树脂型窝沟封闭剂+自酸蚀粘结剂组(SE组),树脂加强型玻璃离子+自酸蚀粘结剂组(SS组)。进行窝沟封闭并记录操作时间与治疗感受度,3、6、12个月复查封闭剂保存情况及患龋情况。结果 (1) SO组62人共纳入228颗牙,SS组63人共纳入234颗,VS组56人共纳入221颗牙;(2)SE组操作时间(181.88±12.37)s及SS组(103.07±11.37)s与对照组SO组操作时间(108.56±8.65)s,差异具有统计学意义(Z=460.163,P <0.001);(3)与另外2组相比,SO组的治疗感受度较差(Z=20.232,P <0.001);(4)3 m复查时,SO组封闭剂保存率和龋发病率分别为100%、0%,SS组保存率和龋发病率为62.1%、2.2%,VS组保存率和龋发病率为93.1%、1.8%;6 m复查时,SO组封闭剂保存率和龋发病率分别为98.2%、1.8%,SS组保存率和龋发病率为52.3%、4.2%,VS组保存率和龋发病率为89.2%、3.3%;12 m复查时,SO组封闭剂保存率和龋发病率分别为95.0%、5.0%,SS组保存率和龋发病率为42.8%、7.2%,VS组保存率和龋发病率为78.9%、6.2%。3次复查中,SO组的保存率最高,3组封闭剂保存差异均具有统计学意义(3 m复查χ^(2) =144.286,P <0.001;6 m复查χ^(2) =159.703,P <0.001;12 m复查χ^(2) =152.945,P <0.001)但3组的防龋效果相似(3 m复查χ^(2) =4.842,P=0.089;6 m复查χ^(2) =2.153,P=0.341;12 m复查χ^(2) =0.915,P=0.613)。结论 自酸蚀粘接剂结合树脂加强型玻璃离子可简化操作步骤、提高患儿的舒适度、且封闭效果较好,对口腔医疗资源匮乏地区封闭技术的推广来说是一种切实有效的选择。Objective To compare the operation time, acceptability and sealing effect of resin-based sealant and resin-reinforced glass ionomer combined with certain adhesive systems applied to seal deciduous molar teeth,so as to provide a more appropriate oral health promotion activity for children in areas with insufficient oral medical resources. Methods The qualified second deciduous molars were randomly divided into three groups:Clinpro TM Sealant + phosphoric acid etching( the control group), Clinpro TM Sealant + Single bond Universal,Clinpro TM XT Vanish + Single bond Universal.The pit and fissure sealant were applied,operation time and treatment sensitivity were recorded. After 3,6,and 12 months,preservation conditions and caries incidence were reviewed.Results (1)A total of 62 people in SO group included 228 teeth,63 people in SS group included 234 teeth,and56 people in VS group included 221 teeth.(2)The operating time of SE group(181.88±12.37) s and SS group(103.07±11.37) s was significantly different from that of SO group(108.56±8.65) in control group(Z = 460.163,P < 0.001).(3) Compared with the other two groups,the treatment sensitivity of SO group was worse(Z = 20.232,P < 0.001).(4) At reexamination 3 months after operation,the preservation rate of sealant and the incidence rate of caries were 100% and 0% in SO group, 62.1% and 2.2% in SS group, and 93.1% and 1.8% in VS group,respectively;At reexamination 6 months after operation,the preservation rate of sealant and incidence rate of caries in SO group were 98.2% and 1.8% respectively,the preservation rate and incidence rate of caries in SS group were52.3% and 4.2%, and the preservation rate and incidence rate of caries in VS group were 89.2% and 3.3%respectively;At reexamination 12 months after operation,the preservation rate of sealant and the incidence rate of caries in SO group were 95.0% and 5.0% respectively;the preservation rate and the incidence rate of caries in SS group were 42.8% and 7.2%,and the preservation rate and the incidence rate of caries i
