根管引流和根尖屏障技术保守治疗囊肿样根尖周病变的30例回顾分析

Retrospective analysis of conservative treatment for 30 cases periapical cyst-like lesions by orthograde decompression and apical barrier

目的:评估根管引流和根尖屏障技术对囊肿样根尖周病变的临床疗效。方法:回顾分析30例囊肿样根尖周病变的患者,经过根管引流和根尖屏障技术保守治疗后,术后3~24个月的临床和影像学资料,评估该方法治疗囊肿样根尖周病变的临床疗效。结果:30例囊肿样根尖周病变中16例已愈合、13例病变改善、1例未愈合。无皮质骨缺损组的病变愈合速率相较于单侧皮质骨缺损和双侧皮质骨缺损愈合速率更快,差异具有统计学意义(P<0.05)。结论:根管引流和根尖屏障技术应用于囊肿样根尖周病变的保守治疗可以获得良好的临床效果。无皮质骨缺损的病变较有皮质骨缺损愈合速率更快。

Objective:To evaluate the effect of conservative treatment orthograde decompression and apical barrier on healing of periapical cyst-like lesions.Methods:A total of 30 patients with periapical cystic-like lesions were retrospectively analysed.All treatments strategy were performed by orthograde decompression and apical barrier.After 3 to 24 months of postoperative follow-up, clinical and X-ray examinations were performed to evaluate the efficacy.Results:Sixteen cases were evaluated as cured, 13 cases were evaluated as improved, and 1 cases as ineffective.The healing rate of lesions in the group without cortical bone defects was significantly faster compared to those with unilateral cortical bone defects and bilateral cortical bone defects, with statistically significant(P<0.05).Conclusion:Conservative treatment by orthograde decompression and apical barrier has a high success rate for periapical cyst-like lesions.The presence of cortical bone defect negatively affected osseous healing.
