The aim of this study was to evaluate the effect of chemo-mechanical caries removal system (Carisoly""¢¥, Medi Team, Sweden) for resin adhesion to carious primary and permanent dentin compared with conventional drilling method. The buccal suface of 92 primary molars and 92 permanent molars were used. Exposed dentins were oc¡þcurred artificial caries. 32 tooth of primary molars and 32 tooth of permanent molars were prepared to observe treated dentin surface with Carisoly¢¥ 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¢¥¢¥" was stronger on the primary dentin than that to perma¡þ
nent dentin, and dentin surface became rougher with treated CarisolvT"¢¥ 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 layerr were 2-4um and 10-15um in thickness, whereas self-etching bonding system were showed only thin hybrid layer(1-2um).
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¢¥¢¥¢¥¢¥ and self-etching priming system were slightly higher than that applied conventional drilling method and self-etching priming system(P>0.05)
