Συγκριτική μελέτη του βαθμού συγκόλλησης μιας κεραμομεταλλικής κονίας με οδοντικούς ιστούς και σύνθετες ρητίνες

BONDING CAPACITY OF GLASS CERMET HAS NOT BEEN EXAMINED YET, IN LABORATORY STUDIES. THE PURPOSE OF THIS IN VITRO INVESTIGATION WAS TO EXAMINE BOND STRENGTHS OFGLASS-CERMET TO ENAMEL, DENTIN AND AUTOPOLYMERIZED COMPOSITE RESINS INTENSILE TEST. THE MATERIALS THAT WERE USED ARE: (A) KETAC-SILVER (GLASS-CERMET), KETAC-FIL (GLASS-IONOMER) ON EVALUATION OF BOND STRENGTH TO DENTAL TISSUES AND (B) KETAC-SILVER, KETAC-BOND (GLASS IONOMER), SILAR (MICROFILLER, COMPOSITE RESIN) P10 (HIGH PACKING, SMALL PARTICLES COMPOSITE RESIN) FOR RETENTION TO COMPOSITE RESINS. GROUPS OF SPECIMENS ARE THE FOLLOWING: (A) 1. ENAMEL, 2. DENTIN (CONTROL), 3. DENTIN PRETREATED WITH 50% CITRIC ACID FOR 30" AND 4 PRETREATED WITH 17% EDTA FOR 60" (B) 1. NO ETCHED SURFACE OF CEMENTS, 2. ETCHED FOR 30" AND 3 ETCHEDFOR 60". STATISTICAL ANALYSIS OF BOND STRENGTH VALUES AND EXAMINATION OF THE FRACTURED SURFACES OF SPECIMENS WITH SFM PROVED: (A) GLASS CERMET BONDED TO ENAMEL AND DENTIN SHOWING NO DIFFERENCES IN COMPARISON TO GLASS-IONOMER (B) PRETREATMENT OF DENTIN SURFACE WITH CITRIC ACID AND EDTA DID NOT IMPROVE BOND STRENGTH OF THE CEMENTS, (C) ETCHING OF CEMENT SURFACES, IMPROVED BONDING OF COMPOSITERESINS, (D) BOND STRENGTH OF GLASS-CERMET TO COMPOSITE RESINS WAS HIGHER THAN GLASS-IONOMER AND (E) ETCHING TIME (30" OR 60") DIDN'T AFFECT BOND STRENGTH BETWEEN CEMENTS AND COMPOSITE RESINS.
