比较了全景、咬翼片和根尖周X线摄影以及探诊对边缘骨水平的测量。共检查了23例患者的237个部位。使用含钢球的夹板拍摄X线片，以计算X线片的放大率。在皮瓣手术前和手术过程中使用相同的夹板进行探查。开放骨测量值代表真实值。所有X线片均由5名观察员进行评估。全景X线片的平均放大率在上牙弓为27%，下牙弓为26%，咬翼片和根尖周片的平均放大率在上牙弓为8%，下牙弓为4-5%。术前探查骨水平是最准确的，与真实值的偏差最多为5%。根尖周X线摄影的准确性高于全景片和咬翼片（p < 0.001）。全景X线摄影的平均准确性略低于咬翼片X线摄影（p < 0.05）。骨丢失的低估率在正断层摄影中为13 - 32%，在咬翼片中为11-23%，在根尖周X线片中为9-20%。观察者之间的放射学方法的变化是实质性的。
Panoramic, bitewing and periapical radiography and probing for measurement of the marginal bone level were compared. Altogether 237 sites of 23 patients were examined. Radiographs were taken with a splint containing steel balls to allow calculation of the enlargement of the radiographs. Probing was done before and during flap surgery using the same splint. The open bone measurement represented the true value. All radiographs were assessed by 5 observers. The mean enlargement of panoramic radiography was 27% in the upper and 26% in the lower arch. For bitewing and periapical radiography, it was 8% in the upper and 4-5% in the lower arch. All methods underestimated the bone loss. Probing bone level before surgery was most accurate, deviating at most 5% from the true value. Periapical radiography was more accurate than panoramic and bitewing radiography (p < 0.001). Panoramic radiography presented a slightly lower mean accuracy than bitewing radiography (p < 0.05). The underestimation of the bone loss ranged from 13 to 32% in orthopantomograms, 11-23% in bitewing and 9-20% in periapical radiographs. The interobserver variation of the radiographic methods was substantial.
