摘要
目的:评价刻意再植术治疗难治性根尖周炎的疗效以及影响再植预后的相关因素。方法:回顾分析2001年因难治性根尖周炎,临床建议拔除患者5例7个患牙,经即刻拔除再植术+根管充填治疗5年后的临床资料。其中,5例患者均为45岁以上,年龄最大56岁,女性3例,5个患牙,3个磨牙,2个前磨牙;男性2例,前磨牙和磨牙各1个。上述患牙均在局麻下拔除术、牙齿离体后30min内完成根尖周变性组织湿法刮除术、根管充填术、牙体缺损即刻解剖性外形修复术,再植复位术。结果:术后5年复查,所有患牙均存留,牙龈附着正常,牙体活动度在Ⅰ度内,咀嚼功能良好,X光检查均达到牙周膜或骨性愈合。结论:根尖生物膜与难治性根尖周炎的发生密切相关,牙齿再植术能有效地清除病灶区的整个生物膜,彻底根治生物膜引起的难治性和慢性感染,为临床降低医源性牙齿缺失提供了一种新途径。
Objective： To evaluate the curative effect of intented replantaffon on refractory and chronic periapical periadontiffs, and to analyse the relative factors. Methods： We reviewed 5 patients, who had 7 implicated teeth to be removed because of refractory and chronic periapical periadontitis. They underwent conversed filling of root canal and instantaneous replanted . All patients were more than 45 years old. 3 females had 5 implicated teeth, including 3 molars and 2 premolars, while 2 males had 1 molar and 1 premolar respectively. All teeth were removed under local anesthesia, wet curaged degenerative periapical tissue, conversed filling of root canal, instantaneous anatomy repaired tooth damnification, and replantated within 30 minutes. Results： 5 years later, each tooth represented normal gingival attachment, the average movement was Ⅰ°. The X - ray examination showed the periodontal membrance healed up. Conclusion： Replantation is widely used to treat traumatic dislocated teeth. The rate of the success is generally shown to be closely related with the hour between dislocation and replacement and the conserving manner of the teeth.
