Outline of Final Research Achievements

Tooth wear is composed of attrition, abrasion, acid erosion and abfraction, and remarkable as tooth surface lose (TSL). In this study, we have investigated the mechanism and diagnosis of TSL to clarify the treatment of TSL. From the result of our clinical research, occlusal surface areas were related with the progression of attrition. The exposition of H2S to enamel resulted in the roughness of the enamel structure. The bond strengthes of MMPs-inhibitor-containing resin adhesive system were not decreased by the addition of EDC 1% or CHX 0.5%. The surface-coating resin system showed good bond strengths to the artificial acid erosion teeth. The platinum-nanocolloid-containing adhesive system did not show the higher bond strengths to carious sclerotic dentin.
