Retrospective analysis of conservative treatment for 30 cases periapical cyst-like lesions by orthograde decom-pression and apical barrier
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 post-operative follow-up,clinical and X-ray examinations were performed to evaluate the efficacy.Results:Sixteen cases were eval-uated as cured,13 cases were evaluated as improved,and 1 cases as ineffective.The healing rate of lesions in the group with-out 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.
