Sistemas adhesivos autograbadores en esmalte: Ventajas e inconvenientes

Abstract

The bond strength to bovine enamel of five self-etching adhesive systems was measured comparing to two total etch adhesive systems and using different application modes (following manufacturers' instructions, with a previous acid etching, duplicating priming time and doubling the number of adhesives' layers). The etching patterns were analized with scanning electron microscopy showing the self-etching adhesives different aggressiveness. All self-etching systems showed reliable bond strength values.
