| 摘 要： | 目的:对比分析锥形束CT与根尖牙片在根折诊断中的诊断价值。方法:选取经临床拔牙或外科探查证实的35 例(37个患牙)根折裂患者,均作CBCT和根尖牙片检查,对比分析图像。结果:37个患牙中,CBCT在检出根折35个,根尖牙片检出折裂线16个。结论:CBCT检知牙根折裂的准确率明显高于根尖牙片,能清晰显示根折位置及类型,对临床制定根折治疗方案有重要应用价值。

| Abstract: | Objective: To compare the diagnostic value of cone beam CT (CBCT) and periapical film in tooth root fracture. Methods: Thirty-seven teeth from 35 patients were included in this study whose roots were fracture confirmed after extraction or surgical exploration. All teeth were examined by both CBCT and periapical film. Radiological images were analyzed and compared. Results: Of the 37 fractured teeth, CBCT detected 35 teeth and periapical film detected 16 teeth. Conclusion: The accuracy of CBCT in detection of tooth root fracture was significantly higher than that of periapical film. The CBCT clearly showed the location and type of root fracture. The CBCT held important clinical value in the treatment planning of tooth root fracture. |
