Abstract: Abstract:Objective:The effects of three different coating methods on the microtensile strength of the dentine dentin were compared.Methods: We selected 30 primary molars, divided into 2 groups (group AE and group XV), according to the different coating methods were divided into 6 subgroups, exposed dentin, with Z350 resin filling, prepared for the cross-sectional area of 1.0mm2 micro tensile specimens subjected to micro tensile strength test specimen fracture surface in the form of transmission electron microscopy (SEM) observation.Results:TIn this experiment, AE2 was measured by micro tensile strength, compared with the other groups, with statistical significance (P < 0.05). The continuous coating two times to obtain micro tensile strength obtained high tensile strength than the other two methods, and the difference was statistically significant (P < 0.05). Scanning electron microscope observation. Most of the type of fracture is the dentin resin interface failure and mixed failure.Conclusions:In this experiment, the adhesive strength of the Adper TM Easy One coating for two consecutive times is good when the resin filling is filled with resin, and it can be popularized in clinical practice.

Key words: Key words:self etching adhesive, coating method, microtensile strength, scanning electron microscope.
