Abstract

Self-etching priming bonding system was recently developed in order to simplify the clinical skills & save chair time after continuous improvements on dentin bonding agents. To test the magnitude of microleakage of a new "self-etching priming bonding agent" using sound premolar 4th, 5th, 6th generation dentin bonding agent was applied. Measure the magnitude of infiltration to the gap of enamel-restoration interface and dentin-restoration interface. After bonding of composite resin to sample surfaces according to the manufactures direction and 500 times thermocycling on dwell time 30 second, and microleakage was measured by the ratio of the depth to the axial wall and the magnitude of infiltration. Afterward analyzed by ANOVA test. The result were as follows ; 1. Enamel groups showed lesser microleakage (Group I, II, III, IV) than dentin groups(Group V, VI, VII, VIII). (p<0.05) 2. There are no statical differences among the dentin groups, in enamel groups, group IV showed more microleakage than group I, II, III. (p<0.05). For a clinical acceptance, better enamel marginal adaptation is required.
