Comparative Study of a Filled and an Unfilled Version of a Dentin Bonding System to Dental Hard Tissues

چکیده
Materials and Methods: For the microtensile test, 12 human extracted molars stored in a 0.5% chloramine T solution were used, providing 3 teeth per adhesive system, half of which were used for bond strength tests on enamel, and the other half for adhesion testing on dentin. Resin composite was bonded incrementally to the prepared surfaces, using the adhesives Adper Scotchbond 1 [Adper Single Bond] and Adper Scotchbond 1 XT [Adper Single Bond 2] (3M-ESPE) according to the manufacturer’s instructions. The bonded specimens were stored in distilled water at 37oC for 24 hours, sectioned into sticks and then subjected to a microtensile bond test. Data was analyzed with two-way ANOVA and Tukey’s test. Additional specimens were immersed in a silver tracer solution for TEM examination of nanoleakage.

Statement of Problem: The use of dentine bondings on enamel and dentin in total etch protocols has recently become popular. Unfilled resin is hydrophobic and dentin bonding is hydrophilic in nature. This chemical difference could be effective in enamel bonding process. Purpose: The aim of this study was to compare the shear bond strength of unfilled resin to dry enamel and dentin bonding to dry...
