Abstract：AIM: To explore the occluding effect of pulsed Nd: YAG laser irradiation combined with 3M ESPE adhesive reagent on human dentinal tubules in vitro. METHODS:30 intact non-carious second molars were extracted because of serious periodontitis. Exposed coronal dentinal tubules were prepared on each tooth. All samples were randomly divided into 3 groups(n=10) and treated with nothing (group A, blank control), Nd:YAG laser irra-diation (group B) and Nd:YAG laser irradiation combined with 3M ESPE adhesive reagent (group C) respevtively. The morphological changes of dentin surface were observed under scanning electron microscopy and the diameters of dentinal tubules in each group were measured. RESULTS: The treatment of group C was more effective than that of group B in occluding dentinal tubules. The diameters (μm) of dentinal tubules of groupA, B and C were 1. 793368 ± 0. 284225, 1. 401832 ± 0. 539471 and 1. 009611 ± 0. 503342 respectively. There was statistical difference between each 2 groups (P<0. 05). CONCLUSION:Pulsed Nd:YAG laser combined with 3M ESPE adhesive reagent is more effective in occluding human dentinal tubules.
