Abstract
Objectives: To investigate the effect of three caries removal methods; air abrasion, papain gel, carbide bur, and water storage on microtensile bond strength of universal adhesives to affected dentin.
Materials and methods: Two universal adhesives; glycero-phosphate dimethacrylate (GPDM) containing OptiBond universal (Kerr Medical, USA) and 10-Methacryloyloxydecyl dihydrogen phosphate (10-MDP) containing Prime&Bond universal (Dentsply Sirona, USA) were used in this study according to their manufacturers' instructions. Forty-eight carious human molars were mounted into acrylic blocks then the coronal enamel and dentin were removed exposing a flat surface of affected dentin. Teeth were divided into two groups (n=24) according to the …
