ENDODONTIC SYSTEMATIZATION

本研究的目的是探索安全、稳定、高效的根管治疗的合理方法。研究结果如下：1.从简化橡胶坝应用的实验角度，证实了通过设置处理装置和改进橡胶坝火焰，缩短了手术时间。在局部麻醉研究方面，证实了骨膜旁和骨膜下注射方法对磨牙下移是有效的，但有时需要联合牙周韧带注射。牙科病房水系统的污染与氯离子浓度有关。支持使用氟碳聚合物作为管道材料来减少对水的污染。研制了一套与超声波牙髓治疗仪相连接的紫外光水流灭菌系统，对水中细菌有较好的杀灭效果。为评价超声根管治疗装置的切割和清洗效果，开展了多方面的研究。研究结果表明，该超声装置工作正常。FC、头孢匹胺为广谱抗生素，采用腔内或腔内给药技术进行检测。结果表明，少量FC腔内药物具有足够的抗菌效果，对组织的刺激性小，本研究的目的主要是通过局部麻醉、橡胶垫、超声根管治疗仪、根管药物和根管充填等综合研究来实现的。

The purpose of this study was to investigate rational methods for the safety, steady, and efficient endodontic treatment.The results were as follows:1. From the view of experiments to simplify the rubber dam application, it was confirmed that the operation time was reduced by device of tretment motion and improvement of rubber dam flame.2. About the local anesthesia study, it was proved that the paraperiosteal and subperiosteal injection methods were effective to lower molar area, however it was sometimes necessary to combine the periodontal ligament injection.3. The contamination of water system in dental unit related to the chloride concentration. It was supported that the contamination of the water was reduced by using the fluorocarbon polymer as piping material.4. Water flow sterilization system using a ultraviolet device, which was connected to ultrasonic apparatus for endodontic treatment, was newly developed, and it worked effectively to decrease bacteria in the water.5. To evaluate the cutting and cleansing efficiency of ultrasonic endodontic unit, multilateral studies were carried out. The results from these studies showed that the ultrasonic device worked functionally.6. FC, and Cefpiramide that was a wide spectrum antibiotic were examined with intracanal or intrachamber medicament technique. It was found that the intrachamber medicament of a small amount of FC showed sufficently antibacterial effect and low tissue stimulus.We conclude that the purpose of this study was mostly accomplished by comprehensive investigations which were composed of local anesthesia, rubber dam, ultrasonic endodontic apparatus, endodontic medicament, and root canal filling.
