不同医生利用CBCT测量牙槽骨高度的可靠性研究
Reliability of cone-beam computed tomography for measuring alveolar bone height by different doctors
摘要
Abstract
Objective:To evaluate of the reliability of cone-beam computed tomography(CBCT)for measuring alveolar bone height by different doctors.Methods:The CBCT images of 89 patients with missed mandibular first molars were evaluated by two independent trained examiners two times with NNT software 4.6.Measurements were taken from the midpoint of alveolar bone crest between mandibular second molar and second premolar to the most superior part of the mandibular canal.The measurement obtained by a radiologist was taken as a gold standard,and the results of the two doctors were analysed by Kappa value.Results:The good rates of two times of each examiner were 91%,90% and 89%,90%.The Kappa values between two times of each examiner were 0.841 and 0.84.The Kappa values for the agreement between the two examiners were 0.334 and 0.362.Conclusion:CBCT is acceptable for alveolar bone linear measurements for its good accuracy and reliability,while it has a tendency difference when measure alveolar bone height by different doctors.关键词
