Abstract

 

The marginal adaptation to dentin cavities of a microfilled restorative resin was measured with and without previous use of a light-activated dentin-bonding agent. The investigation was carried out on butt-joint cavities prepared in extracted human teeth. Increasing the irradiation time of the bonding agent from 10 to 80 sec reduced significantly both the width and the extent of the marginal contraction gap
