To compare the use of film-based periapical radiographs and digital panoramic images displayed on monitor and glossy paper in the assessment of the periapical status of the teeth.
A total of 86 subjects were examined. All participants underwent a full-mouth radiographic survey (14 periapical radiographs) and a digital panoramic radiography. The periapical status of all appraised teeth was assessed.
Periapical radiographs allowed the assessment of the periapical status of a significantly higher percentage of teeth (87.4%) Digital radiography had a significantly reduced potential to allow assessment of the periapical status (p<0.01). Only 58.0% and 34.3% of teeth could be appraised using digital panoramic images displayed on monitor and glossy paper respectively (p<0.01). The total percentage of teeth with periapical pathosis was four-fold higher when assessed with digital panoramic images displayed on glossy paper compared with periapical radiographs (p<0.01).
Periapical radiographs allowed the assessment of a significantly higher percentage of teeth when comparing to digital radiography, which had a significantly lower potency in the assessment of periapical status of the teeth. Digital panoramic images displayed on a monitor resulted in a significantly higher percentage of appraised teeth compared to digital images displayed on glossy paper. Apical periodontitis was scored more often on paper than on screen, and more often on screen than in periapical radiographs.
比较在监视器和光面纸上显示的数字化全景图像与传统胶片根尖片在评估牙齿根尖状态方面的应用。
共 86 名受试者接受了全口曲面断层片（14 张根尖片）和数字化全景片检查。评估所有评价牙的根尖状态。
根尖片可评估的牙齿比例明显更高（87.4%），数字化放射摄影术评估的可能性明显降低（p<0.01）。只有 58.0%和 34.3%的牙齿可以分别在监视器和光面纸上显示的数字化全景图像上进行评估（p<0.01）。与根尖片相比，在光面纸上显示的数字化全景图像评估的根尖病变牙齿比例高四倍（p<0.01）。
与数字化放射摄影术相比，根尖片可评估的牙齿比例明显更高，数字化放射摄影术在评估牙齿根尖状态方面的潜力明显降低。与在光面纸上显示的数字化图像相比，在监视器上显示的数字化全景图像导致可评估的牙齿比例显著更高。与屏幕相比，在纸上记录根尖周炎的频率更高，而与根尖片相比，在屏幕上记录的频率更高。
