生物活性玻璃与铒激光联用对磨切牙本质模型的封闭效果

Abstract

Abstract: Objective To evaluate the occluding effect of bioactive glass combined with Er laser irradiation on abrasion cutting dentine model.Methods 45 dentine discs were prepared and the treating sides were roughly grinded,finely grinded and polished.They were randomly divided into 5 groups with different treatments： Group A （no treatment as a control）,Group B （bioactive glass）,Group C （Er,Cr：YSGG laser irradiation）,Group D （bioactive glass followed by Er,Cr：YSGG laser irradiation）,and Group E （Er,Cr：YSGG laser irradiation followed by bioactive glass）.The occluding effect and mineral content were examined by scanning electron microscopy （SEM） and Xray energy spectrum analysis （EDXA）.Results Micrographs of SEM showed excellent occluding effect in Group B,C,D and E,and the dentinal tubule exposure rates were D （0.044%±0.003%）

Key words: bioactive glass, Er laser, abrasion cutting dentine model, SEM
