对破坏广泛的根尖周病变传统多采用根管治疗后再做外科手术治疗,对病变超过根长1/2或直径大于6mm者多采用拔牙治疗。自1974年以来,作者对198位患者根尖病变直径超过5mm,5～6mm59例,6～14mm155例的214只患牙行保守的塑化治疗,并追踪观察为期1～13年。患者年龄从11岁～72岁,男性92人,女性106人,上双尖牙20颗,下双尖牙12颗,上、下磨牙分别是36颗和146颗。于治疗后3个月、6个月、1年、2年、4年～13年作复诊检查。凡治疗后无任何症状,功能良好X线片显示病变完全消失,牙槽骨新生,硬骨板形成为治愈;X线片显示病变有明显缩小,但未完全消失为进步;X线片上病变无明显变化为
To destroy a wide range of periapical lesions more traditional use of root canal treatment and then do surgical treatment of lesions over the root length 1/2 or diameter greater than 6mm who use more extraction treatment. Since 1974, the author of 198 patients with apical lesions more than 5mm in diameter, 5 ~ 6mm59cases, 6 ~ 14mm155cases 214 cases of teeth with conservative plasticization treatment, and follow-up observation period of 1 to 13 years. The patients ranged in age from 11 to 72 years old, with 92 males and 106 females, 20 on canines, 12 under canines, 36 on upper and lower molars, and 146 on lower molars. 3 months after treatment, 6 months, 1 year, 2 years, 4 years to 13 years for follow-up examination. Where there is no any symptoms after treatment, good function X-ray showed lesions completely disappeared, alveolar bone formation, the formation of bone plate to be cured; X-ray showed lesions significantly reduced, but not completely disappeared for progress; X-ray lesions were not significantly Change to
