【摘要】 目的颌骨囊肿摘除术后,探讨MTA与银汞合金作为根尖倒充填材料的预后效果。方法收集以MTA行倒充填术的15例患者,共20颗牙齿,以银汞合金材料行倒充填术的15例患者,共20颗牙齿,两组均进行囊肿摘除术,并且同期行根尖倒充填术,对两组临床资料的一般情况,术区肿痛发生率及术后疗效进行统计学分析。结果 MTA组术后6个月、12个月治愈率高于银汞合金材料组(P<0.05);两组中术区肿痛发生率及术后3个月治愈率比较,差异无统计学意义(P>0.05)。结论选择MTA作为根尖倒充填材料,有助于提高临床疗效。更多还原

【Abstract】 Objective To investigate the effect of prognosis on MTA and silver amalgam as root-end filling materials after the jaw cyst excision. Methods A total of 20 teeth with 15 cases of MTA filling, and a total of 20 teeth were treated with retrograde filling with amalgam materials in 15 patients were collected. Cyst enucleation was performed in the two groups, and retrograde filling was performed at the same time. The general situation of the two groups of clinical data, the incidence of postoperative swelling pain and postoperative efficacy were statistically analyzed. Results The cure rate of group MTA at 6 and 12 months was higher than that of amalgam group(P<0.05). There was no significant difference between the two groups in the incidence of swelling pain and the cure rate at 3 months after operation(P>0.05). Conclusion The choice of MTA as a filling material for root tip filling is helpful to improve the clinical efficacy.更多还原
