The validity of a quantitative digital subtraction technique was investigated in vitro when influenced by the following aspects; the material enveloping the aluminium reference wedge, the radiation quality used to produce the radiographs and the effe

The use of an aluminium reference object in radiographical studies permits quantification of periodontal bone changes. A digital subtraction techninque was developed for this purpose. To obtain optimal performance, two corrections have to be applied

Changes in the periodontium produced by removal of bone cylinders at one interdental site of a dry human mandible, were recorded radiographically. These artificial lesions had diameters of 0.3 mm increasing to 1.4 mm in steps of 0.1 mm. Radiographs w
