Effect of thickness on shrinkage stress and bottom-to-top hardness ratio of conventional and bulk-fill composites
(2021-12-01)
This study evaluated the effect of the material thickness on shrinkage stress and bottom-to-top hardness ratio of conventional and bulk-fill composites. Six commercial composites were selected based on their different ...

Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
(2009-06-01)
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...

Long-term surface hardness and monomer conversion of a nonofilled and a microhybrid composite resin
(2013)
Objective: This study aims to evaluate the degree of conversion (DC) and hydrolytic degradation through the Vickers hardness test (HV) of a nanofilled (Filtek™ Z-250, 3M) and a microhybrid (Filtek™Supreme-XT, 3M) composite ...
