Comparative depth of cure among two light-cured core build-up composites by surface vickers hardness.

Frontiers in Dentistry, 2012
Depth of cure of composite material is restricted and it depends on many parameters such as thickness. The aim of this in-vitro study was to evaluate the depth of cure of two light-cured core build-up composites (Quixfil and Photocore) in different ...
