Nanotube-modified dentin adhesive--physicochemical and dentin bonding characterizations.

Objective: The aim of this study was to investigate the effect of aluminosilicate clay nanotubes (Halloysite, HNT) incorporated into the adhesive resin of a commercially available three-step etch and rinse bonding system (Adper Scotchbond Multi-Purpose/SBMP) on dentin bond strength, as well as the effect on several key physicochemical properties of the modified adhesive.

Methods: Experimental adhesives were prepared by adding five distinct HNT amounts (5-30 wt.%) into the adhesive resin (w/v) of the SBMP dentin bonding system.

Effects of resolvin D1 on cell survival and cytokine expression of human gingival fibroblasts.

Background: Tissue breakdown in periodontitis is initiated by bacteria, such as Porphyromonas gingivalis, and is caused largely by host responses. Resolvins protect the host against acute inflammation by blocking the migration of polymorphonuclear neutrophils to initiate resolution. The effects of resolvins on human gingival fibroblasts (HGFs) are unknown.
