Bond Strength of Injectable Composites Under Different Enamel Treatments and Bonding Strategies
ABSTRACT Objective The effectiveness of enamel acid etching may be enhanced when combined with additional surface treatments, such as diamond bur grinding. However, there are no reports of the effect of enamel grinding and bonding strategies when a universal adhesive and highly filled flowable composites are used.

ABSTRACT Objectives The long‐term esthetic performance of CAD/CAM ceramic restorations may be influenced by repeated exposure to therapeutic mouthrinses. This study evaluated the effects of chlorhexidine, essential oil‐based, and stannous fluoride mouthrinses on the color stability (ΔE) and surface roughness (Ra) of glazed and polished CAD/CAM ceramics.
