Effects of Brown and Green Propolis on Bond Strength of Fiberglass Posts to Root Canal Dentin.

Introduction: The purpose of this study was to evaluate the effect of brown and green propolis on bond strength of the fiberglass posts to root canal dentin, and to compare it with conventional endodontic irrigants.

Methods And Materials: Sixty bovine teeth were selected, decoronated and randomly distributed into six groups (=10), according to the irrigation solution: 0.9% saline solution (Control); 2% chlorhexidine (CHX); 5% malic acid (MA); 0.

Effect of post space preparation drills on the incidence of root dentin defects.

Objectives: This study investigated the incidence of root dentin defects after the use of different post space preparation (PSP) drills.

Materials And Methods: Seventy-two bovine incisors were selected and obtained 14-mm-long root sections. Twelve roots served as controls with no intervention (G1).
