The current adhesive system is becoming more simple and easier, while in vitro bond strength to tooth substance is becoming better as new products appear. However, the in vitro data or values are usually obtained from sound ground and flattened tooth substance. Clinically, a tooth (i.e. adherent) which needs a restoration is usually diseased or in infirm condition, and has some sort of depression or cavity. The purpose of this study was to measure the microtensile bond strength of a one-bottle resin adhesive system (Clearfil Tri-S Bond: Kuraray Medical) to cariesaffected dentine, which lies in a class 1 cavity floor. Furthermore, the relationship between the value of DIAGNOdent™(KaVo) of adherent dentine and bond strength was also examied. ・The mean micro-tensile bond strength to cariesaffected dentine (CD)/sound dentine (SD) in MPa (±s.d.) was 5.86±1.96/14.77±3.30, and CD was significantly lower than SD (p<0.01). With the one-step adhesive, it was difficult to gain a high bond strength to caries-affected dentine. ・The correlation coefficient of the bond strengths and DIAGNOdent^<TM> values of CD/SD was 0.0659/0.2080. In both cases, there was no correlation between the bond strength and DIAGNOdent^<TM> value. The DIAGNOdent™ value of CD was significantly higher than that of SD. ・Regardless of the type of dentine, it seemed difficult to anticipate the level of micro-tensile bond strength from the value of DIAGNOdent™
