Influence of specimen size and regional variation on long-term resin-dentin bond strength

Abstract:

The influence of the dimension of a bonded specimen stored prior microtensile testing and its regional variation on the resin-dentin bond strength (BS) over time was analyzed. Two adhesive systems were applied and composite resin crowns were constructed. BS was expressed as an index that considers cohesive failures and estimated values of premature debonded specimens. It was shown that the amount of decrease in BS is dependent on the specimen size and the decrease in BS is greater for peripheral specimens than more centrally located specimens.
