STUDY ON RESIN DIRECT PULP CAPPING OF INFECTED DENTAL-EFFECT OF DENTIN BONDING SYSTEM AND HIGH OXIDATION POTENTIAL WATER-

探讨了在树脂粘接材料中加入抗菌剂（万古霉素、甲硝唑、HY-agent）直接盖髓的可行性。本文研究了用高氧化电位水代替化学消毒剂对牙本质粘接强度的影响。结果表明：单纯用高氧化电位水处理，不能获得与牙本质良好的附着力。采用10-3（10%柠檬酸+3%FeCl_2）和高氧化电位水处理，处理时间和处理方法的合理组合，可获得良好的粘接效果。虽然这些实施例中的一些识别出脓肿形成，但当使用添加了抗菌剂的粘合材料时，没有使用添加了抗菌剂的粘合材料时，不能识别出脓肿形成。在本试验条件下，高氧化电位水的联合使用效果不理想。

The possibility of direct pulp capping of infected dental pulp with resin bonding material which added antibacterial agents (vancomycin, metronidazol, HY-agent) was examined. The effect of application of high oxidation potential water, used as a disinfectant instead of the chemical surgery, on bond strength to dentin was examined. The following were obtained : By only treatment of high oxidation potential water, the good adhesion was not obtained to dentin. The good adhesion was obtained by appropriate combination of processing time and method of processing of 10-3 treatment (10% citric acid and 3% FeCl_2) and high oxidation potential water.In the vital pulp of maxilla posterior tooth of the Wistar rat, which contaminated with A.naeslundii, the pulp reaction capped with resin bonding agent which added antibacterial agents (2% vancomycin) was histopathologically examined. Though some of these examples recognized abscess formation, when bonding material added no antibacterial agent was used, abscess formation could not be recognized, when bonding material added antibacterial agent was used. In present experiment, the effect of using high oxidation potential water jointly could not be accepted.
