摘要：

The influence of a Ho:YAG laser and nano-hydroxyapatite (HAp) coating on the surface roughness (Ra) and shear bond strength (SBS) of lithium disilicate ceramics (LDC) bonded to dentin with resin cement of varying viscosity following exposure to thermal aging has been studied. One hundred and fifty-three LDC discs were prepared and randomly allocated into three groups, based on their surface pretreatment. Group 1:10 % HFA + S, Group 2: Ho:YAG laser, and Group 3: Nano-HAp coating. Ra was measured using a profilometer and the surface topography was assessed by means of scanning electron microscopy (SEM). Adhesion of prepared LDC discs to the dentinal substrate was performed using high-viscosity and low-viscosity resin cement and the discs were exposed to different storage conditions. Their SBS and failure were assessed with a UTM and stereomicroscope. One-way ANOVA and Tukey post- hoc tests were used for intergroup comparison. Group 2 (Ho:YAG laser) exhibited the highest Ra scores and Group 3 (HAp coatings) demonstrated the lowest Ra value. Group 2A (Ho:YAG laser + HIGH) samples achieved the highest SBS values at baseline. However, Group 3A (HAp coatings + HIGH) displayed the lowest bond score. A Ho:YAG laser and nano-HA can be used as an alternative surface conditioning regime with a positive influence on Ra and SBS of LDC.
