The purpose of this study was to compare the normal and two times of application time of six self-etching primers applied to enamel using microshear bond strength (uSBS) test and the finding of scanning electronic microscope (SEM).Crown of sixty human molars were bisected mesiodistally and buccal and lingual enamel of crowns were partially exposed and polished with 600 grit SiC papers. They were divided into one of two equal groups subdivided into one of six equal groups (n = 10) by self-etching primer adhesives.After the same manufacture' s adhesive resin and composites were bonded on the enamel surface of each group, the bonded specimens were subjected to uSBS testing and also observed under SEM.In conclusion, generally two times of primer application time increased the enamel uSBS, especially with the statistical increase of bond strength in adhesives involving high-pH primers.

This study compared the microtensile bond strength (μ TBS) of single step adhesives to different dentin depths.Superficial or deep dentin was exposed in 30 molar teeth by sectioning immediately under the DEJ or 1.5 ㎜ area from central pit, respectively. After polishing with 600-grit SiC paper, the dentin surfaces were assigned to three groups: AQ group-AQ Bond, L-Pop group-Adper Prompt L-Pop, Xeno group-Xeno III.The bonded specimens were sectioned into sticks and subjected to μ TBS testing with a crosshead speed of 1 ㎜/minute. The results of this study were as follows;The μ TBS to superficial dentin was higher than that to deep dentin in all group. The μ TBS of Xeno group was significantly higher than that of L-Pop group and AQ group in both superficial and deep dentin (p < 0.05). [J Kor Acad Cons Dent 30(4):319-326, 2005]
