目的评价锥形束CT(CBCT)与曲面体层片(OPG)检查在根折病例中的诊断价值.方法对比研究30名患者的31颗根折裂患牙的 OPG 和 CBCT 检查结果.结果在31颗牙根折裂患牙中, OPG 能明确诊断的有23颗牙齿,而 CBCT 能明确诊断所有患牙.结论从 CBCT 图像上能清晰辨别牙根纵折裂纹和纵折区牙槽骨的变化,对于根折的早期诊断意义优于 OPG.

Objective To evaluate the diagnostic value of cone beam computed tomography(CBCT) and orth-pantomography(OPG) for root fracture. Methods Comparing the results of 31 teeth from 30 suspected patients of root fracture examined by CBCT and OPG. Results Root fractures were confirmed in all the 31 teeth by CBCT and subsequent extraction while OPG only detected fractures in 23 teeth. Conclusion CBCT images can more distinctly demonstrate the fracture lines, and surrounding bone loss in three dimensions. And CBCT is supe-rior to OPG in detection of root fractures.
