ErCr:YSGG激光对牙本质界面粘结强度及形态结构的影响

Abstract

Abstract: Abstract：Objective To investigate the effects of ErCr:YSGG Laser Irradiation on microtensile bond strength of two adhesive systems to dentin.Methods: 20 freshly extracted intact human molars were prepared and randomly divided into four groups(n=5): group1 : Cut by laser +adhension with ONE—Step Plus; group2: Cut by traditonal methods +adhension with ONE—Step Plus;group3: Cut by laser +adhension with +Futurabond DC;group4: Cut by traditonal methods + adhension with +Futurabond DC. Then a resin composite buildup was made for each specimen about 10mm, which was sectioned along its long axis to obtain 15 beams(1.0mm×1.0mm) every subgroup for the microtensile bond strength(MTBS) test. Fracture sites were observed using a light microscope. Statistical analysis was performed using one-way ANOVA and Tukey’s tests with the probability level set at α= 0.05.Morphologic structure of the adhesive interfaces was examined by scanning electron microscopy (SEM). Results: Mean bonding strengths（MPa）for each group were16.37±3.46， 17.74±3.92，16.48±2.85，12.37±3.71Mpa. Group4 had the lowest bond strength（P <0.05）. Conclusions:Er,Cr：YSGG laser can improve the effect on bonding between dentin and self-etched resin cement.
