Does the use of a novel self-adhesive flowable composite reduce nanoleakage?

Objective: The aim of the study reported here was to evaluate the performance of a self-adhesive flowable composite and two self-etching adhesive systems, when subjected to cyclic loading, in preventing the nanoleakage of Class V restorations.

Methods: Wedge-shape Class V cavities were prepared (4×2×2 mm [length × width × depth]) on the buccal surfaces of 90 sound human premolars. Cavities were divided randomly into three groups (n=30) according to the used adhesive (Xeno(®) V [self-etching adhesive system]) and BOND-1(®) SF (solvent-free self-etching adhesive system) in conjunction with Artiste(®) Nano Composite resin, and Fusio™ Liquid Dentin (self-adhesive flowable composite), consecutively.

Microshear bond strength and interfacial morphology of etch-and-rinse and self-etch adhesive systems to superficial and deep dentin.

Objective: To compare microshear bond strength (uSBS) of two pairs of etch-and-rinse and self-etch adhesives to superficial and deep dentin.

Method And Materials: Occlusal surfaces of 40 sound extracted noncarious human molars were ground to obtain flat dentin surfaces (20 superficial and 20 deep dentin). Twenty-four teeth were used for uSBS test and 16 for scanning electron microscopic examination.
