摘要: Durack C, Patel S, Davies J, Wilson R, Mannocci F. Diagnostic accuracy of small volume cone beam computed tomography and intraoral periapical radiography for the detection simulated external inflammatory root resorption. International Endodontic Journal, 44, 136–147, 2011. Abstract Aim  To compare in an ex vivo model ability digital (CBCT) to detect resorption lesions, investigate effect altering degree rotation CBCT scanners X-ray source imaging detector on same lesions. Methodology  Small large (EIR) lesions were created roots 10 mandibular incisor teeth from three human mandibles. scans with 180° 360° radiographs, using a photostimulable phosphor plate system, taken prior after creation EIR lesions. The relocated their original sockets during imaging. Receiver operator characteristic (ROC) analysis kappa tests reproducibility techniques carried out sensitivity, specificity, positive negative predictive values (PPV NPV) also determined each technique. Results  overall area under ROC curve (Az value) was 0.665, compared Az 0.984 0.990 CBCT, respectively (P < 0.001). sensitivity specificity significantly better than regardless rotation, had superior NPVs (P < 0.01) PPVs (P < 0.001) radiography. intra- inter-examiner agreement it whether or taken. Examiners able identify exact location artificial they radiographs (P < 0.001). Conclusion  is reliable valid method detecting performs operating no at small, artificially cavities device rotation.
