Abstract：AIM:To compare the sealing effect of Nd:YAG laser,resin infiltration and combined application on dentin tubules.METHODS:50 dentin-sensitive models were prepared and randomly divided into 5 groups(n=10 in each group):blank control(group A),Nd:YAG laser(group B),Infiltrating resin(group C),Infiltrating resin+Nd:YAG laser(group D),Nd:YAG laser+Infiltrating resin(group E).The morphology of the dentin tubules was observed by scanning electron microscope after the samples were treated,and the diameter,open area and sealing rate of the dentin tubules were measured and calculated by Image J image processing software.RESULTES:The diameter and open area of dentinal tubules were group A＞group B＞group C＞group D＞group E.The sealing rate of dentinal tubules was group E＞group D＞group C＞group B.There was a statistical difference between the groups(P＜0.05).CONCLUSION:Nd:YAG laser and infiltrating resin have good sealing effect on dentinal tubules.The combination of the two can increase the sealing effect and provide a new treatment strategy for the treatment of dentin sensitivity.
