Abstract:
Objectives:To evaluate the adhesive effect of resin and dentin perpared by air abrasion. Methods:Dentin of 48 permanent molars was exposed and treated with ① air sand blasting+whole acid corrosion+Estet. X TM,② air sand blasting+SE BOND,③ air sand blasting+Esthet. X TM,④Turbine+whole acid corrosion+Esthet.X TM respectively with 12 samples in each group. Then resin adhesive was applied.Microtensile testing was used to examine the microtensile bond strength. SEM was used to observe the change of resin jags. Results:The microtensile bonding strength in group ①,②,③ and ④ was 27.96?1.42, 29.84?2.56,14.48?2.45 and 27.73?1.48 respectively (① vs ③,② vs ③ and ③ vs ④ P
