Composite resin microhardness: the influence of light curing method, composite shade, and depth of cure.

Aim: The aim of this study was to investigate the influence of light curing method, composite shade, and depth of cure on composite microhardness.

Methods And Materials: Forty-eight specimens with 4 mm of depth were prepared with a hybrid composite (Filtek Z-100, 3M ESPE); 24 with shade A1 and the remaining with shade C2. For each shade, two light curing units (LCUs) were used: a quartz-tungsten-halogen (QTH) LCU (Optilight Plus - Gnatus) and a light emitting diode (LED) LCU (LEC 470 II - MM Optics).

Microleakage of seven adhesive systems in enamel and dentin.

Aim: The aim of this study was to evaluate the microleakage of seven adhesive systems on two substrates (enamel and dentin).

Methods And Materials: Class V cavities were performed in buccal and lingual surfaces of 56 bovine incisors. The cervical margin was located in dentin and the incisal margin in enamel.
