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

探讨了添加抗菌剂（万古霉素、甲硝唑、hy -剂）的树脂粘接材料直接覆盖感染牙髓的可能性。研究了用高氧化电位水代替化学手术对牙本质黏结强度的影响。结果表明：仅对高氧化电位水进行处理，不能获得与牙本质良好的附着力。采用10-3处理（10%柠檬酸+ 3% FeCl_2）和高氧化电位水的处理时间和处理方法，获得了良好的附着力。用添加抗菌剂（2%万古霉素）的树脂粘接剂对污染的Wistar大鼠上颌后牙的牙髓进行组织病理学检查。虽然这些例子中有一些识别出了脓肿的形成，但当结合材料不添加抗菌剂时，当结合材料添加抗菌剂时，脓肿的形成无法识别。在目前的实验中，高氧化电位水联合使用的效果不能被接受。

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.
