Effect of an MDP-containing cleaner on bonding of a self-adhesive resin composite to salivary-contaminated root dentin
Source abstract
Abstract
This study evaluated the effect of an MDP-containing cleaner on the bond strength of a self-adhesive resin composite (SAR) to saliva-contaminated bovine root dentin. Dentin surfaces were ground with #600 SiC and contaminated with artificial saliva for 20 s. Specimens were divided into four groups: water rinse (WA), 10% citric acid-3% ferric chloride solution (10-3), MDP-containing cleaner (KC), and non-contaminated (NC). SAR was applied according to the manufacturer's instructions. After 24 h of water storage at 37°C, μTBS was measured (n=10). KC showed no significant difference in μTBS compared with the NC (p>0.05), while no measurable bond strength was obtained for the WA and 10-3. Mixed failures comprising cohesive failure within dentin, cohesive failure within resin, and adhesive failure at the dentin-resin interface were more frequent in the NC. KC effectively removed contaminants and restored bonding performance. This method offers a promising restorative protocol for challenging clinical settings.
