To compare panoramic radiographs made with the Scanora dental program and bitewing radiographs in the assessment of marginal bone tissue.
Panoramic and posterior bitewing radiographs were made for 96 consecutive patients. Six observers assessed marginal bone level, and five observers identified the presence or absence of vertical bone defects and furcation involvements. Observer agreement was calculated.
Assessments of the marginal bone level with the two methods were identical for 57% of the sites. If a difference of one score was allowed, assessments for 95% of the sites were in agreement. Vertical bone defects and furcation involvement were detected with an agreement of 93%. Ranges of kappa indexes for intra-observer agreement on assessments of the marginal bone level were 0.37-0.46 in panoramic radiography and 0.31-0.55 in bitewing radiography. Ranges for agreement on detection of vertical bone defects were 0.52-0.63 and 0.47-0.56 and on detection of furcation involvements 0.64-0.79 and 0.66-0.77, respectively. The kappa index for inter-observer agreement on marginal bone level was 0.28 for panoramic and 0.29 for bitewing radiography. Corresponding figures for detection of vertical bone defects were 0.38 and 0.35 and for detection of furcation involvement 0.56 and 0.67.
For those sites or teeth that are possible to assess, the diagnostic information available with Scanora panoramic radiography is comparable to that with bitewing radiography for marginal bone tissue. Therefore, Scanora dental panoramic radiography is a valuable diagnostic alternative in the primary examination of the periodontal status.
比较使用Scanora牙科程序拍摄的全景X线片与咬合翼片在评估边缘骨组织方面的情况。
为96例连续患者拍摄全景片和后牙咬合翼片。6名观察者评估边缘骨水平，5名观察者确定垂直骨缺损和根分叉病变的有无。计算观察者间的一致性。
两种方法对57%的位点边缘骨水平的评估结果相同。若允许相差一个评分，则95%的位点评估结果一致。垂直骨缺损和根分叉病变检测的一致性为93%。全景X线片评估边缘骨水平时观察者内一致性的kappa指数范围为0.37 - 0.46，咬合翼片为0.31 - 0.55。垂直骨缺损检测一致性的范围分别为0.52 - 0.63和0.47 - 0.56，根分叉病变检测一致性的范围分别为0.64 - 0.79和0.66 - 0.77。全景X线片边缘骨水平观察者间一致性的kappa指数为0.28，咬合翼片为0.29。垂直骨缺损检测的相应数值为0.38和0.35，根分叉病变检测的相应数值为0.56和0.67。
对于那些可以评估的位点或牙齿，Scanora全景X线片提供的边缘骨组织诊断信息与咬合翼片相当。因此，Scanora牙科全景X线片是牙周状况初步检查中有价值的诊断选择。
