説明
Resin-coating technique is unique to produce tight sealing film on the dentin surface with an adhesive resin and a low viscosity composite. For indirect restoration, it enables us to cover prepared surface immediately after preparation to minimize further pulp irritation from mechanical, thermal and bacterial insults during impression taking, temporary restoration, and final cementation. In this study, the influences of residual monomer on resin-coated dentin and also two types of impression materials on bond strengths of resin cement to resin-coated dentin were evaluated. The impression materials used in this study were reversible hydrocolloid (Aromaroid, GC) and silicone rubber (Exafine, GC). Clearfil Linerbond IIΣ and Protect Liner F (Kuraray, Osaka, Japan) were applied to bovine dentin to make a substrate. The resin cement, Clapearl DC (Kuraray, Japan) was cemented on resin-coated dentin. Tensile bond strength was measured at crosshead speed of 2 mm/min. The results indicated that reversible hydrocolloid did not influence the bond strengths of resin cement to resin-coated dentin, whereas silicone rubber ruduced the bond strengths. However, after impression taking, the bond strength recoverd when the contaminant from impression materials was wipe off with an alcohol cotton pellet. In conclusion, the use of reversibie hydrocolloid is proper for resin-coating technique.
