树脂加强型玻璃离子黏结剂的黏结效果及对牙齿状况的影响观察

目的：观察树脂加强型玻璃离子黏结剂的黏结效果及其对牙齿状况的影响情况。方法：选取本院因正畸治疗拔除的96颗牙齿为研究材料,将其随机分为对照组（京津釉质黏结剂组）和观察组（树脂加强型玻璃离子黏结剂组）,每组各48颗,然后将两组不同时间后的不同黏结部位及环境下的黏结强度、残留情况及微渗漏情况进行比较。结果：观察组不同时间后的不同黏结部位及环境下的黏结强度均大于对照组,且干预后12、24h及48h残留情况及微渗漏情况也均优于对照组,差异具有统计学意义（P〈0.05）。结论：树脂加强型玻璃离子黏结剂的黏结效果较佳,且对牙齿状况的不良影响相对较小,综合应用价值更高。

Observation on the bonding effects of resin reinforced glass ionomer cements and its influence on the dental status

Objective：To observe the bonding effects of resin reinforced glass ionomer cements and its influence for the dental status.Methods：A total of 96teeth which were extracted for orthodontic treatment were selected and they were randomly divided into control group（Jingjin enamel bonding agent group）and observation group（resin reinforced glass ionomer cements group）with 48teeth in each group, then the bonding strength of different bonding site and environment at different times,residue situation and microleakage situation of two groups were compared.Results：The bonding strength of observation group with different bonding site and environment at different times were all bigger than those of control group,residue situation and microleakage situation at 12h,24hand 48hafter the intervention were all significantly better than those of control group（all P0.05）.Conclusion：The bonding effect of resin reinforced glass ionomer cements is better,and its bad influence on dental status is relatively smaller,thus its comprehensive application value is higher.
