酚醛树脂液在1912年Albreecht用于充填根管以来,经Sommer改良,故又称为Albrecht-sommer法。我国在50年代初开始应用于临床,以后经各地同道改进了处方和使用方法,并深入研究了物理性能、在组织学方面也做了初步观察,取得了一定的成绩。临床上各地开展后的疗效报告很多,但缺乏系统的组织病理学研究。现在临床上常用的处方不外乎两类:一类是三种液体,即醛、酚和催化剂的分装;另一类是两种液体,即酚和催化剂合装。本文研究目的是用两种处方的酚醛树脂液充填猴牙根管,观察尖周病的愈合情况。材料和方法成年猴10只。选用全部后牙,在硫贲妥钠麻醉下开髓,去除牙髓组织,开放于口腔环境3个月,造成尖周病变,拍摄X线片确定后,清理髓腔,封FC棉球一周,用下列两种酚醛树脂液(均系新鲜配制),
Phenolic fluid was modified by Sommer since Albreecht was used to fill the root canal in 1912, so it is also known as the Albrecht-Sommer method. In the early 1950s, China began to apply it to the clinic. Afterwards, various local people improved prescriptions and methods of use, studied the physical properties in depth, and made initial observations in the field of histology. Some achievements have been made. There are a lot of reports about the curative effect after the clinical operation in various places, but there is no systematic histopathological study. Now commonly used in clinical prescriptions are nothing more than two categories: one is the three kinds of liquid, that aldehyde, phenol and catalyst packaging; the other is two kinds of liquid, that is, phenol and catalyst combined. The purpose of this study is to use two kinds of prescriptions of phenolic resin solution to fill the canine root canal and observe the healing of the apical disease. Materials and Methods 10 adult monkeys. Select all the posterior teeth, anesthesia in the sulfur-sodium propolis under the pulp, removal of pulp tissue, open in the oral environment for 3 months, resulting in periapical lesions, shooting X-ray film is determined, clean the medulla, seal FC cotton ball a week, With the following two phenolic resin solution (both freshly prepared system),
