目的:探讨银粉玻璃离子用于根尖倒充填术治疗根尖孔未闭慢性根尖周炎的临床疗效。方法:根管口未闭慢性根尖周炎患者26例(26颗患牙),先行根管治疗,1周后以银粉玻璃离子行根尖倒充填术,术后每隔3个月定期进行临床检查并拍摄X线根尖片,术后1年评价手术疗效。结果:26例中,未能定期复查2例,从本研究中剔除;完成根管治疗及接受根尖倒充填术24例,有效21例,无效3例,总有效率为88%。术后3个月时复查患牙见窦管重新形成2例(上颌前磨牙和下颌前磨牙各1例)。结论:以银粉玻璃离子作根尖倒充填术的倒充填材料,短期疗效良好。
Objective: To investigate the clinical efficacy of silver powder glass ion for apical flos-tip filling in the treatment of chronic apical periodontal apical apical foramen. Methods: Twenty-six patients (26 teeth) with chronic apical periodontitis were treated with root canal. One week later, apical filling was performed with silver ion glass ionomer. The operation was performed regularly every 3 months Clinical examination and radiography X-ray film, 1 year after surgery to evaluate the effect. Results: Of the 26 cases, 2 cases were not reviewed regularly and excluded from this study. Twenty-four cases were completed root canal therapy and apical filling, 21 cases were effective and 3 cases were ineffective. The total effective rate was 88%. At 3 months postoperatively, 2 cases (3 cases of maxillary premolar and mandibular premolar respectively) were found again. CONCLUSION: Short-term curative effect is good for inverted filling material filled with silver powder glass ion tip.
