“…Analysis of the bond interface revealed that most failures in the investigated groups affected the enamelresin interface, consistent with the literature. 15,17 The data of the present study corroborate the findings in the literature, 15,17 indicating that most failures in microtests are of the adhesive mode, which ensures bond strength results more appropriate to the dental substrate.…”

“…15 Studies that assessed the bond strength using micro-shear and microtensile tests reported that the results from micro-shear test seem to be more adequate when the strength of different adhesive systems is evaluated, 16,17 presenting a greater number of adhesive failures.…”

“…For enamel, we would have expected an increase in bond strengths compared with the original G- 64 It has been reported that lTBS values tend to be higher because the defect concentration in the small cross-sectional interfacial areas is lower. 65 Although Pashley and Tay 39 reported that the cohesive strength of the adhesive layer might be more relevant than the etching potential of an enamel adhesive for acidic SE adhesives, 10,66 the hydrophobic resin coat application, which increases the cohesive strength of the adhesive layer, was not able to improve the enamel-dentin bonds in our study.…”

“…Previous studies have shown that a 60-second chlorhexidine application has an effect on deciduous teeth. 25,26 Because the microtensile bond strength is a reliable in vitro metric to evaluate bond strength 27 and a positive correlation between microtensile and microshear bond strength tests was demonstrated, 28 the methodology utilized in this study was able to detect the differences observed between the tested groups. Furthermore, the common method used to evaluate simulated bond interface aging is to prepare specimens in beam forms with an adhesive 1 mm 2 in area and to soak the bonded specimens at 37 °C.…”
