Marginal adaptation of resin in relation to application technique and use of a dental adhesive system.
Class V abrasion, erosion and caries lesions restored with composite resin seem to be more susceptible to microleakage, because the gingival margin is usually placed in cementum and/or dentine. The purpose of this study was to evaluate the microleakage, in vitro, of a dentinal bonding system using a technique of restoration with a positive and a negative control. This study was accomplished using extracted human teeth and dye penetration technique. The teeth were examined for microleakage after one month. It was concluded that in the gingival wall of the cavity microleakage was significantly reduced when the dentinal bonding agent and composite resin was placed and polymerized incrementally from enamel, to cementum.
