Abstract：Objective To assess the diagnostic accuracy of cone beam computed tomography in comparison with digital radiography for detecting simulated complete vertical root fractures and imcomplete vertical root fractures in extracted hu-man teeth. Methods Sixty teeth were endodontically prepared and divided into 3 groups,2 experimental and 1 control. The teeth in experimental groups were artificially fractured and fixed together with 20 complete VRFs(group one)and 20 imcomplete VRFs(group two). Twenty teeth in control group were kept intact(group three). Three observers evaluat-ed the digital radiagraphs and CBCT images in terms of accuracy for VRFs detection. Results The overall accuracy for detecting VRFs was significantly higher for CBCT compared with the digital radiagraphs(P<0.05). The Fisher analysis showed no significant difference between complete RVFs and imcomplete RVFs for CBCT(P>0.05). Conclusion The CBCT technique has higher accuracy than 2-D radiography for in vitro dignosis of VRFs;we can use CBCT to detect ear-ly VRFs.
