作者研究用规定的真空程度和局部达松伐电疗相结合治疗尖周炎的效果。患者和方法慢性尖周炎95例,男45,女50,年龄18～50岁,患牙114颗(纤维型尖周炎13,肉芽肿型35,肉芽型66),单根牙53颗,多根牙61颗,一次完成治疗41颗,两次以上完成73颗。用磷酸锌粘固粉作根管充填,达到或稍微超出根尖孔.研究组73颗牙,根管充填以后用规定的真空和局部达松伐电疗,治疗机套管头对准患牙根尖相应处的牙龈,接通真空器,随后接通局部达松伐电疗 The authors studied the effect of treating periapsis with a prescribed degree of vacuum combined with local exposure to dacronized electrotherapy. Patients and Methods Chronic periapical 95 cases, male 45, female 50, aged 18 to 50 years old, 114 teeth (fibrous periapitis 13, granuloma 35, granulation 66), single root 53, Multi-root teeth 61, a treatment completed 41, more than 73 completed 73. Zinc phosphate cement as root canal filling, reaching or slightly beyond the apical foramen.Study group of 73 teeth, after filling the root canal with a prescribed vacuum and local daptosection electrotherapy, the treatment of the casing head aligned with the root tip The corresponding gingiva, connected to the vacuum device, followed by access to local daptosection electrotherapy
