由牙周膜持续炎症引起的炎症性渐进性牙根外吸收在临床上是比较常见的。许多学者报道抗菌素/皮质类固醇制剂对此有较好疗效,但缺乏动物实验资料支持。本文目的是研究局部应用抗菌素/皮质类固醇制剂是否能消除牙周膜内残留的炎症。材料和方法实验动物为4只成年猴。戊基巴比妥钠麻醉下拔除切牙,暴露牙髓,测量工作长度。用1根H型锉导入根管,撕碎牙髓,然后逆时针方向旋转小心退出,以便将撕碎的牙髓留在根管内。窝洞用氧化锌丁香油粘固粉暂封,1小时后行牙再植,不用夹板固定。
Inflammatory progressive extra-root absorption caused by persistent inflammation of the periodontal ligament is clinically more common. Many scholars have reported that antibiotics / corticosteroid preparations have a good effect on this, but the lack of animal experimental data support. The purpose of this paper is to investigate whether topical application of antibiotic / corticosteroid preparations can eliminate residual inflammation in the periodontal ligament. MATERIALS AND METHODS Experimental animals were 4 adult monkeys. Pentylene pentobarbital anesthesia removal of incisors, exposing the pulp, measuring the length of work. Use a H-file to introduce the root canal, tear the pulp, and then rotate it counter-clockwise carefully to allow the shredded pulp to remain in the root canal. Nest hole with zinc oxide clove oil cement powder temporary closure, 1 hour after tooth replantation, without splint fixation.
