Abstract

Background: The aim of this study was to investigate the effect of different concentrations of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) monomer in one-step self-etch experimental adhesives on dentinal microshear bond strength (μSBS), their degree of conversion and bonded micro structure. Material and Methods: Composite resin cylinders (Clearfil AP-X) were bonded on human sound molar dentinal surfaces by using five experimental one-step self-etching adhesives (1-SEAs) containing 0 (E0), 5 (E5), 10 (E10), 15 (E15), 20 (E20) (by weight) 10-MDP monomer and Clearfil S3 Bond (CS3) as a control. After 24 hours, microshear bond strength was tested. The degree of conversion was also measured using Fourier transform infrared spectroscopy. Interfacial ultrastructure was observed under a scanning electron microscope in all the groups. Results: A higher microshear bond strength was observed with adhesives containing 10 and 15 10-MDP in comparison to study groups (P < 05). Clearfil S3 Bond and 10 MDP had a significantly greater degree of conversion than other groups (P < 05). Conclusions: The amount of functional monomer in 1-SEAs influences both the bonding performance and degree of conversion; 10 10-MDP showed the best combination of bond strength and degree of conversion. © Medicina Oral S.
