Abstract:AIM:To evaluate the dentin sealing ability of SinglebondTM Universal adhesive(SB) and All-Bond Universal adhesive(AB).METHODS:Boxes were prepared on the occlusal surface of 50 extracted third molars to expose 1 mm×2 mm dentin.Then the dentin bonding models were randomly divided into 5 groups:GroupⅠ(single-layer daub with SB), GroupⅡ(double-layer daub with SB), GroupⅢ(single-layer daub with AB), GroupⅣ(double-layer daub with AB), and GroundⅤ(blank control).All specimens were stained with 20 g/L methylene blue and root tips were ground layer-by-layer under a dental operating microscope.Teeth were cut in buccal-lingual direction once blue points were discovered.The largest vertical distance of dye penetration were evaluated by vernier caliper.The data were analysed.RESULTS:Infiltration was observed in all groups.Pairwise comparison showed that there was statistically significant among Groups(P<0.05).The infiltration value in GroupⅠand Ⅲ was higher than that in GroupⅡ and Ⅳ(P<0.05;between group Ⅰand Ⅲ, P>0.05;between groupⅡ and Ⅳ, P>0.05).CONCLUSION:SB and AB can effectively seal dentin, the double-layered adhesive is more effective to that of single-layered adhesive.
