Objectives: To evaluate the adhesion durability of eleven adhesives including Tokuyama Bond Force.

Methods: Resin composite (Estelite Sigma / Tokuyama Dental Corp.) was bonded to bovine enamel and dentin prepared with 600-grit SiC paper using eleven different adhesives; One-step; BF: Bond Force (Tokuyama Dental), TS: S³ Bond (Kuraray), GB: G BOND (GC), X4: XenoIV and X5: Xeno V (Dentsply), iB: i Bond (Heraeus Kulzer), OP: Optibond All-in-One (Kerr), EB: Easy Bond, and SB: Scotch Bond (3M-ESPE), Two-step; SE: SE Bond (Kuraray), and SP: Single Bond Plus (3M-ESPE). The tensile bond strength both enamel (E) and dentin (D) were measured after immersion in water at 37 ^oC for one day (Init.) and followed by 3,000 thermal cycles at 4 and 60 ^oC (3000).

Results: Means (sd, n=6) of bond strength (MPa) are summarized in a table.

Conclusions: Bond Force showed an adhesion durability comparable or superior to SE Bond, a two-step bonding material.
