The purpose of this study was to investigate the influence of Ca(OH)2 on NaClO in the dissolution of organic tissue. In this study, we used gelatine as a protein which was treated with 5% NaClO[0 mg-Ca(OH)2 group], 5% NaClO+1 mg/ml-Ca(OH)2[1 mg-Ca(OH)2 group], 5% NaClO+0.1 mg/ml-Ca(OH)2[0.1 mg-Ca(OH)2 group], or 5% NaClO+0.01 mg/ml-Ca(OH)2 [0.01 mg-Ca(OH)2 group], respectively. The dissolution of gelatine was greater in the 0 mg-Ca(OH)2 group than in the 1 mg-Ca(OH)2 group (p<0.01). In addition, increases in pH were dependent on Ca(OH)2 concentration. Free radicals were measured using the ESR spin-trapping method. Generation of DMPO-X was found to be increased by Ca(OH)2 concentration, and diminished time dependent. These results suggested that gelatine dissolution with NaClO was inhibited by Ca(OH)2 concentration.
