目的模拟尤其是数字口腔内x线摄影在评估牙间骨水平方面的准确性有待进一步研究。本研究的目的是比较临床和影像学骨水平评估与术中骨水平登记(1)，并确定导致牙间骨水平评估不准确的临床变量(2)。材料与方法选取17例牙周炎患者的49个牙间部位进行研究。评估方法包括垂直相对探测附着水平（RAL-V）、模拟和数字口内x线片和骨探测仪。后者被认为是真正的骨水平。5名审查员评估了所有的x光片。结果所有评估方法对真实骨水平的估计均显著低估，模拟x线摄影平均低估2.7 mm，数字x线摄影平均低估2.5 mm， RAL-V平均低估1.8 mm，无瓣抬高的骨探测平均低估0.6 mm （p < 0.001）。x线片对（前）磨牙区真实骨水平的低估较高(p
Objectives The accuracy of analogue and especially digital intra-oral radiography in assessing interdental bone level needs further documentation. The aim of this study was to compare clinical and radiographic bone level assessment to intra-surgical bone level registration (1) and to identify the clinical variables rendering interdental bone level assessment inaccurate (2).Materials and methods The study sample included 49 interdental sites in 17 periodontitis patients. Evaluation methods included vertical relative probing attachment level (RAL-V), analogue and digital intra-oral radiography and bone sounding without and with flap elevation. The latter was considered the true bone level. Five examiners evaluated all radiographs.Results Significant underestimation of the true bone level was observed for all evaluation methods pointing to 2.7 mm on average for analogue radiography, 2.5 mm for digital radiography, 1.8 mm for RAL-V and 0.6 mm for bone sounding without flap elevation (p < 0.001). Radiographic underestimation of the true bone level was higher in the (pre)molar region (p
