To evaluate the color stability of three resin-based materials continuously exposed to various staining agents. DUC, Olivier,

Thirty-nine conventional posterior composite fillings were placed according to the three-sited light curing technique using Tetric, a fine hybrid composite material, and Syntac,

A new polishing brush with abrasive bristles for polishing resin-based restorations was tested to determine if it polishes restorations, including those with concave

Marginal adaptation was assessed before and after each phase of mechanical loading (250,000 cycles at 50N, 250,000 cycles at 75N and 500,000 cycles at 100N); internal adaptation

After 500,000 and 1,000,000 loading cycles, the use of Prime & Bond, together with an immediate composite insertion (PB-IP), resulted in a marginal adaptation on

ΔE00 values were calculated as color difference between the median of each resin composite material at 0.5-mm thickness and individual L*a*b* values at the same thickness

This in vitro study generated data on the quality of marginal adaptation, fracture resistance and retention of several indirect adhesive composite configurations on
