Observation of the influence of chemomechanical caries removal on dentin adhesion by scanning electron microscope / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To observe the influence of chemomechanical caries removal on dentin adhesion by scanning electron microscope.</p><p><b>METHODS</b>The ultrastructure of dentin surfaces and adhesives-dentin bonding interfaces after caries removal by chemomechanical method or drilling were observed.</p><p><b>RESULTS</b>Less smear layer in dentin surface, resin tags in the interface between dentin and Prime&Bond NT/compomer and numerous resin tags and more uniform and closer hybrid layer in the interface between dentin and Adper Prompt-L-Pop/composite were found in chemomechanical preparation than in drilling preparation.</p><p><b>CONCLUSIONS</b>Chemomechanical caries removal can benefit dentin adhesion.</p>
