根管充填是根管治疗的一个重要步骤,充填恰当与否,直接影响根管治疗的近、远期效果。目前,临床上往往凭医生指感和患牙感觉估量根充效果,其结果如何呢?本文通过临床50例根充总结,对该有关问题作一探讨,欢迎同道指导。临床资料共40人50支根管,男15人,女25人,年龄12～71岁。50支根管中上前牙占92％,被充填牙病因56％为龋病继发病,其次为外伤牙。充填前X线片示根尖周情况:有29牙无异常,有6牙呈云絮状透影,面积1×2～8×5mm,有15牙透影边界清晰,面积1×2～10×5mm有1牙根过长,冠:根=1:1.7,1牙根过短,冠:根=1:0.7。充填前均经扩根4～6~#、消
Root canal filling is an important step in root canal treatment. Whether the filling is proper or not directly affects the short-term and long-term effects of root canal therapy. At present, clinicians often rely on the doctor's sense of feeling and the feeling of the root canal to assess the effect of root-filling, what is the result? In this paper, 50 cases of clinical root-filling conclusion, the relevant issues for a discussion, welcome to peer guidance. A total of 40 clinical data 50 root canal, 15 men and 25 women, aged 12 to 71 years. In 50 cases, 92% of the upper anterior teeth were root canal, 56% of the teeth were filled with dental caries, followed by the traumatic teeth. Filling before the X-ray shows the periapical circumstance: there are 29 teeth without abnormalities, 6 teeth was cloud flocculation, the area of 1 × 2 ~ 8 × 5mm, 15 teeth transparent shadow boundary, an area of 1 × 2 ~ 10 × 5mm has a long root, crown: root = 1: 1.7, 1 root is too short, crown: root = 1: 0.7. Before filling by root expansion 4 ~ 6 ~ #, elimination
