van den Breemer CRG, et al. - The microtensile bond strength (μTBS) of resin-based composite (RBC) to dentin was examined following different immediate dentin sealing (IDS) strategies and surface-conditioning (SC) methods and on two water storage times. Researchers randomly divided 48 human molars into eight experimental groups involving four different IDS strategies—IDS-1L with one layer of adhesive, IDS-2L with two layers of adhesive, IDS-F with one layer of adhesive and one layer of flowable RBC, and DDS (delayed dentin sealing) with no layer of adhesive (control)—and two different SC methods—SC-P with pumice rubbing and SC-PC with pumice rubbing followed by tribochemical silica coating. After one week and after six months of water storage, the μTBS test was performed and was recorded as the “immediate” and “aged” μTBS, respectively. To determine the μTBS, they stressed composite-adhesive-dentin microspecimens (0.9×0.9×8–9 mm) in tension until failure. For all experimental groups, failure of the specimens was reported mainly at the adhesive-dentin interface. The application of IDS that results in higher bond strength, may benefit dentin exposure during clinical procedures for indirect restorations. Cleaning with solely pumice or pumice followed by tribochemical silica coating were identified to have no significant differences.
