Shear bond strengths of six bonding systems using the pushout method of in vitro testing

Oper Dent. 1998 Mar-Apr;23(2):69-76.


The newest generation of bonding systems consolidates multiple components into fewer containers in order to simplify clinical procedures and save clinicians time. Six newer adhesive systems (Scotchbond Multi-Purpose Plus, PROBOND, OptiBond FL, Prime & Bond, One Step, and Tenure Quik) were tested for in vitro shear bond strength (SBS) of a hybrid composite to both superficial and deep dentin at 24 hours and 6 months employing a pushout test method. Results showed significant differences in SBS between superficial and deep dentin for both 1-day and 6-month values for all adhesive systems except Tenure Quik. The SBS of OptiBond FL increased significantly for both superficial and deep dentin after 6 months' storage in 37 degrees C water. None of the other adhesive systems showed a significant change in SBS at 6 months. There appear to be several advantages to the testing method.
