Clinical effect of microscopic periapical surgery combined with MTA apical filling in treatment of chronic api-cal periodontitis
摘要
Abstract
Objective To observe the clinical effect of microscopic periapical surgery combined with (mineral triox-ide aggregate (MTA) apical filling in treatment of chronic apical periodontitis. Methods A total of 64 patients with 91 teeth of chronic apical periodontitis, which couldn't be treated with root canal treatment, were selected and randomly as-signed into two groups. 32 patients with 43 teeth in the control group were treated with traditional surgery combined with amalgam filling. 32 patients with 48 teeth in the experimental group were treated with microsurgical apical surgery combined with MTA apical filling. Patients were followed for 12 months. The healing of periapical lesionwere assessed by clinical symptoms and X-ray examination every three months. Results In the experimental group, 27 cases cured, 17 cases improved, the success rate was 91.67% (44/48). In the control group, 19 cases cured, 12 cases improved, the success rate was 72.09%(31/43). The success rate in experimental group was significantly higher than the control group (x2= 5.997, P = 0.014). Conclusion Effect of microscopic periapical surgerycombined with MTA apical filling in treatment of chronic periapical periodontitis is satifactory.关键词
