Dental adhesives and strategies for displacement of water/solvents from collagen fibrils.

Objectives: To evaluate the influence of temperature of evaporation in adhesive systems with different solvents on the apparent modulus of elasticity and mass change of macro-hybrid layers modified by proanthocyanidins (PACs).

Methods: Adhesive resin beams (A) from Single Bond Plus (SB), Excite (EX) and One Step Plus (OS) were prepared after solvent evaporation at 23°C or 40°C (n=12). Macro-hybrid layers (M) (n=12) were prepared using demineralized dentin beams sectioned from extracted human third molars.

Nanomechanical properties, SEM, and EDS microanalysis of dentin treated with 2.5% titanium tetrafluoride, before and after an erosive challenge.

The aim was to assess the nanohardness (H) and the reduced modulus of elasticity (Er ) of 2.5% titanium tetrafluoride (TiF4 ) modified dentin, before and after an erosive challenge with 0.3% citric acid (CA).

Distance and protective barrier effects on the composite resin degree of conversion.

Context: The food wrap films are used to cover the tip of curing light units in order to avoid contamination and prevent damage to the light guide. However, their effects on resin polymerization are not fully known.

Aims: We investigated the effects on restoration efficiency of a food wrap protective barrier used on the tip of curing light units.

Effects of silane application on luting fiber posts using self-adhesive resin cement.

Purpose: To evaluate the effects of different glass-fiber post surface treatments on the bond strength to root dentin.

Materials And Methods: Fifty bovine incisors were used in this study. After removing the crowns, the teeth were endodontically treated.
