Abstract | Background. Dentine affected by amelogenesis imperfecta (AI) is histologically altered following loss of the hypoplastic enamel and becomes hypermineralized, which would make bonding less predictable. Aim. This study examined the effect of etching time on the microtensile bond strength (μTBS) to AI-affected primary dentine. Design. Flat coronal dentine surface was obtained from extracted AI-affected and noncarious primary molars. Teeth were etched either for 15 or for 30 s using 34% phosphoric acid. Prime & Bond® NT™ (Dentsply De Trey), an etch-and-rinse adhesive, was applied to dentine surfaces, air-dried and light-cured, followed by composite build-ups. The bonded teeth were sectioned into beams of 0.8 mm2 and stressed to failure under tension. Representative fractured beams from each group were examined under scanning electron microscopy. Results. The extended etching time had an adverse effect on the μTBS for the normal dentine, while no significant difference was found for AI-affected dentine. When the AI-affected dentine was etched for 30 s, the fracture occurred in the demineralized dentine at the base of the hybrid layer. Conclusion. Bonding to AI-affected dentine compromised the bonding of the etch-and-rinse adhesive. The bonding could not be improved by increasing etching time. © 2008 BSPD, IAPD and Blackwell Publishing Ltd. |
