Optimal strategies for the application of an adhesive differ between enamel and dentin because differences in their composition. The development systems has mainly focused on bonding dentin, rather than enamel, by etching with phosphoric acid (PA). Dental technologies continue to rapidly advance, various have been developed since study Buonocore 1955. He introduced acid-etch technique. Then, et...

The aim of this study is to assess the quantitative ions changes in enamel occlusal surfaces affected by white-spot and brown-spot dental caries. Energy dispersive X-rays analysis (EDX) has been used for qualitative and quantitative chemical analysis of 30 enamel samples (10 sound enamel samples, 10 white-spot enamel samples, 10 brown-spot enamel samples). For samples with white-spot and brown-...

OBJECTIVES The purpose of this study was to evaluate the effects of two different desensitizers (Hemaseal & Cide and Aqua Prep F) on the microleakage of ceramic inlay restorations luted with adhesive resin cement. METHODS Cylindrical Class V cavities were prepared on the buccal surfaces of thirty extracted human third molars. One of the desensitizers (either Hemaseal&Cide, Advantage Dental Pr...

OBJECTIVE This study determined the ultimate tensile strength (UTS) of enamel (E), dentin (D) and dentin-enamel junction (DEJ) using the microtensile technique. It was hypothesized that the UTS of dental structures varies according to location and nature. METHODS Intact occlusal enamel surfaces from extracted human third molars were etched with 37% phosphoric acid and bonded with a one-bottle...
