Influence of Different Etching Modes on Bond Strength to Enamel using Universal Adhesive Systems.

Introduction: The adhesive systems and the techniques currently used are designed to provide a more effective adhesion with reduction of the protocol application. The objective of this study was to evaluate the bond strength of universal adhesive systems on enamel in different etching modes (self-etch and total etch).

Materials And Methods: The mesial and distal halves of 52 bovine incisors, healthy, freshly extracted, were used and divided into seven experimental groups (n = 13).

Effects of the Residues from the Endodontic Sealers on the Longevity of Esthetic Restorations.

The substances used in the root canal treatment, especially sodium hypochlorite solution and oxidant agents, can negatively interfere on the bond strength of the adhesive systems to dentin and on the dental crowns fracture resistance.(1,2).
