Abstract

A tensile testing jig was designed to test adhesion between various materials and tooth surfaces, and between materials of various consistencies, modes of setting and properties. This study examined the adhesion of both flowable and condensable, light cured and chemically cured, direct and indirect restorative materials to dentin. All materials were mixed and placed according to manufacturer's directions. The bonds were tested in tension after 24 hours. The substrate was dentin, except in group 1. Results in MPa +/- SD: 1. Photobond & Photoposterior to enamel 15.84 +/- 3.93; 2. Superbond C&B and metal inlay 6.20 +/- 3.00; 3. SuperBond C&B and amalgam 5.76 +/- 1.89; 4. All-Bond and metal inlay 4.46 +/- 1.16; 5. Mirage Bond and Newbond and amalgam 2.97 +/- 0.85; 6. Vitrebond 2.06 +/- 0.95; 7. Newbond and amalgam 1.70 +/- 0.61; 8. Ketac-Bond 0.73 +/- 0.40. The groups (2,3,4), (4,5), (5,6,7) and (6,7,8) were not significantly different at the 95% confidence level, calculated by the Student-Newman-Keuls test. The testing method was useful for all materials studied.
