我们通过学习史俊南、肖明振教授的《根管治疗术新理论》,于1988年始,采用根管糊剂充填根管治疗尖周窦道,取得了理想的效果.共治疗376人、426牙,其中男206人、女170人,年龄4～56岁.均为慢性尖周炎并发皮肤窦道,按史氏二次法根管治疗术治疗,即第一次开髓,清理扩大根管,封药消毒;第二次用根管糊剂加牙胶尖充填根管.术后2周,临床观察如无主观症状,窦道愈合,即为成功;如仍有主观症状,窦道未愈合,即为失败.结果见表1.在失败的30牙中,发现前牙多因有早接触或根管充填不全,后牙多因漏掉1～2个根管未预备、充填之故,经重新治疗,均取得理想的效果.对成功的病例,追踪观察1年以上的有102
We learned from the “new theory of root canal therapy” by Professor Shi Junnan and Xiao Mingzhen that the root canal was filled with endodontic paste and the ideal sinusoid was obtained by the end of 1988. A total of 376 people, 426 teeth, Including 206 males and 170 females, aged 4 to 56. All chronic sinusitis complicated with sinus skin, according to Shi's second root canal therapy treatment, the first open pulp, clean up and expand the root canal, The second time with root canal paste plus gutta percha filling root canal.After 2 weeks of clinical observation, if there is no subjective symptoms, the sinus healed, that is successful; if there is still subjective symptoms, the sinus is not healing , The result is shown in Table 1. In the failed 30 teeth, found that the anterior teeth due to early contact or root canal insufficiency, the back teeth due to missed 1 to 2 root canal is not prepared, filling it, After re-treatment, have achieved the desired results.For successful cases, follow-up observation of more than 1 year there 102
