BackgroundThis study aims to evaluate the accuracy of cone beam computed tomography（CBCT）and periapical radiography in diagnosing root resorption and verify the influence of filling material in detecting these insulins.MethodsDigital periapical radiographs and CBCT images of patients with root resorption and a history of dental trauma from a radiology clinic回顾性分析。样本包括40颗牙根吸收的牙齿和20颗作为对照的正常牙齿。图像由两名放射科医生和两名牙髓科医生进行分析。测定其敏感性、特异性和准确性。kappa系数评估interobserver协议和t检验确定显着差异之间的成像methods.ResultsThe准确性CBCT诊断外部（P = 0.0144）和内部（P = 0.0038）炎症吸收显着高于根尖周造影。置换性吸收两组间差异无统计学意义（P > 0.05）。结论CBCT在诊断牙外伤后根管内外炎性吸收方面上级数字化根尖片，可作为根管治疗后根管吸收病变的鉴别诊断。
BackgroundThis study aimed to evaluate the accuracy of cone beam computed tomography (CBCT) and periapical radiography in diagnosing root resorption and verify the influence of filling material in detecting these lesions.MethodsDigital periapical radiographs and CBCT images of patients with root resorption and a history of dental trauma from a radiology clinic were reviewed retrospectively. The sample comprised 40 teeth with root resorption and 20 normal teeth as controls. Images were analysed by two radiologists and two endodontists. The sensitivity, specificity and accuracy were determined. The kappa coefficient assessed interobserver agreement and the t test determined significant differences between the imaging methods.ResultsThe accuracy of CBCT in diagnosing external (P = 0.0144) and internal (P = 0.0038) inflammatory resorption was significantly higher than for periapical radiography. For replacement resorption, no statistical difference was noted (P > 0.05). In endodontically treated teeth, CBCT was statistically superior in diagnosing root resorption (P = 0.0138).ConclusionsCBCT was superior to digital periapical radiography in diagnosing external and internal inflammatory root resorption after dental trauma and can be considered in the differential diagnosis of resorptive lesions in teeth with endodontic treatment.
