髓室底穿孔是临床牙体深龋破坏严重或牙体牙髓病治疗过程中意外产生的,特别是陈旧性髓室底穿孔,根分叉部骨质吸收,肉芽组织增生,治疗修复非常困难,既往均予以拔除,近年来我们用复方甲硝唑粘固粉进行底穿封闭治疗与修复患牙38例,取得了满意效果。 1 临床资料 本文对象均为磨牙,男23例。女15例,年龄最大56岁,最小6岁,牙位分布各1颗,5颗,16颗,4颗,8颗,38颗牙中,有2颗为意外底穿,其余均为深龋所致。 2 方法 配方:甲硝唑粉、碘仿粉、氧化锌丁香油粘固粉。操作方法:首先去净髓室病变组织及腐质,刮除髓室底部增生肉芽组织。以副肾素小棉球压迫止血。以樟脑酚或碘复小棉球消毒窝洞,吹干窝洞,扩根管,并于各根管内置入根管扩大针以防止根管阻塞,取适量复方甲硝唑粘固粉,以丁香油调拌至
Perforation of the pulp chamber at the bottom of the clinical deep carious destruction of dental caries or dental pulp in the course of the accidental treatment, especially in the old perforation of the pulp floor, root bifurcation of bone absorption, granulation tissue proliferation, the treatment is very difficult to repair , The past are to be removed in recent years, we use compound metronidazole cement powder to wear at the end of wear and closure of the treatment of 38 cases of teeth, and achieved satisfactory results. 1 clinical data of this article are molars, 23 males. Female 15 cases, the oldest 56 years old, minimum 6 years old, the distribution of each tooth 1, 5, 16, 4, 8, 38 teeth, 2 accidental wear, the rest are deep caries Due. 2 recipe: metronidazole powder, iodoform powder, zinc oxide clove oil cement. Method of operation: first go to the pulp chamber lesion tissue and rot, scraping the bottom of the pulp chamber hyperplasia granulation tissue. With adrenal small cotton balls to stop bleeding. Camphor phenol or iodine complex cotton ball disinfecting cavity hole, blow dry holes, expand the root canal and root canal in each root canal to expand the needle to prevent root canal obstruction, take the appropriate amount of metronidazole cement powder to Clove oil mix to
