EDTA Conditioning Increases the Long-term Microtensile Bond Strength to Sclerotic Dentin Mediated by Self-etch Adhesives.

Purpose: To evaluate the immediate and 12-month microtensile bond strength (μTBS) of two self-etch adhesives on sclerotic dentin with or without previous EDTA conditioning. The conditioning pattern and the relative area of open dentinal tubules were also evaluated.

Materials And Methods: Twenty-eight bovine incisors with naturally exposed sclerotic dentin were used.

Effects of different treatments on chemical and morphological features of eroded dentin.

To evaluate the treatment of eroded dentin (Sensodyne Repair & Protect™, Er:YAG laser and combinations). The occlusal surfaces of 25 third molars were sectioned 1.5 mm in thickness.

Effect of dentin roughness on the adhesive performance in non-carious cervical lesions: A double-blind randomized clinical trial.

Objective: This double-blind randomized clinical trial evaluates the influence of dentin roughening (RO) on the clinical behavior of a new universal multi-mode adhesive (Tetric N-Bond Universal; Ivoclar-Vivadent) applied as self-etch and as etch-and-rinse in non-carious cervical lesions (NCCLs).

Methods: A total of 192 restorations were randomly placed in 48 patients according to the following groups: ER - Etch-and-rinse (no preparation); SE - self-etch (no preparation); ER+RO and; SE+RO. The resin composite Empress Direct (Ivoclar-Vivadent) was placed incrementally.

Collagen cross-linkers on dentin bonding: Stability of the adhesive interfaces, degree of conversion of the adhesive, cytotoxicity and in situ MMP inhibition.

Objective: To investigate the effect of collagen cross-links on the stability of adhesive properties, the degree of conversion within the hybrid layer, cytotoxicity and the inhibition potential of the MMPs' activity.

Methods: The dentin surfaces of human molars were acid-etched and treated with primers containing: 6.5wt% proanthocyanidin, UVA-activated 0.

Five-year Effects of Chlorhexidine on the In Vitro Durability of Resin/Dentin Interfaces.

Purpose: To evaluate the effect of an acid containing 2% chlorhexidine (Ac/CHX) or a 2% CHX aqueous solution (Aq/CHX) on the immediate and 5-year bonding properties of resin/dentin interfaces produced by two adhesives. The presence of CHX in these interfaces was also evaluated under micro-Raman spectroscopy.

Materials And Methods: Forty-two molars were ground to expose a flat dentin surface.
