抄録

Bacterial infection to the dentin surface of the prepared teeth is considered to be one of the important factors that cause pulpal inflammation or secondary caries. NaOCl solution is used as a disinfectant, but the application of the NaOCl solution to dentin surface is known to markedly decrease the adhesive strength of 4-META/MMA-TBBO resin cement to dentin.<BR>The purpose of this study was to find a way to recover the adhesive strength of 4-META/MMA-TBBO resin cement to dentin after reduction by sterilization with the NaOCl solution.<BR>After sterilization with the NaOCl solution, three solutions, 3% hydrogen peroxide, 5% sodiumthiosulfate, and 5% ascorbic acid, were used to neutralize the remaining Na0Cl, but the recovery of adhesive strength was 20-50% in comparison with only etching treatment.<BR>In case of the neutralization with both the solutions and ultrasonic cleaning, the adhesive strength recovered approximate to that of only etching treatment.
