The aim of this study was to evaluate the effect of chemo-mechanical caries removal system($Carisolv^{TM}$, Medi Team, Sweden) for resin adhesion to carious primary and permanent dentin compared with conventional drilling method. The buccal surface of 92 primary molars and 92 permanent molars were used. Exposed dentins were occurred artificial caries. 32 tooth of primary molars and 32 tooth of permanent molars were prepared to observe treated dentin surface with $Carisolv^{TM}$ and conventional drilling method by SEM. Other tooth were prepared to measure resin-dentin shear bonding strength according to caries removal methods and dentin adhesive system. Two adhesive systems and a composite resin were used; single bonding agent(Scotchbond Multi-Purpose Plus, 3M) and self-etching bonding system(Prompt L-pop, 3M ESPE), and a composite resin (Z-250, 3M). The results were as follows : 1. The removal effect of carious dentin on $Carisolv^{TM}$ was stronger on the primary dentin than that to permanent dentin, and dentin surface became rougher with treated $Carisolv^{TM}$ than drilling method. 2. Acid-etched dentin surfaces were showed smoothening without smear layer. 3. In specimen applied single bonding system hybrid layer and adhesive layer were $2-4{\mu}m$ and $10-15{\mu}m$ in thickness, whereas self-etching bonding system were showed only thin hybrid layer($1-2{\mu}m$). 4. The shear bonding strength of group applied single bonding agent was higher than that applied self-etching priming system(P<0.05). 5. The shear bonding strength of group applied $Carisolv^{TM}$ and self-etching priming system were slightly higher than that applied conventional drilling method and self-etching priming system(P>0.05).

$Carisolv^{TM}$ system was developed for removal of carious dentin with chemo-mechanical method by Swedish researcher. $Carisolv^{TM}$ is composed of 0.5% NaClO and three kinds of amino acid, i.e. glutamic acid, leucine and lysin. After these agents are mixed together, the gel mixed is applied to carious dentin and the carious dentin is removed with hand instrument without using burs. The mechanism of softening the dentin is postulated that the degenerated collagen by caries is chlorinated and the decomposed. But the details of the mechanism are not clarified yet.(omitted)
