[Radiographic interpretation of experimentally produced bone lesions in dry human mandibles. 2].
Bone defects comparable to clinical situations were simulated in a group of dry human jaws, using stell fissure and round burs of different sizes. The closen areas were previously photographed, radiographed and used as control. The bone defects were also photographed and radiographed in each stage of the experiments. A radiograph was always taken as a contrast. The final results were: the contrasting "mésio-distal" destruction on part of the interradicular septal only became evident when in reached the internal surface of the tongue and/or inner-ear cortices; the manifestation of radiographics images of the artefacts confined to the cortex bone depended directly on the depth and amplitude of the same; the defects produced into the alveolar edge did not present any X-ray alterations that could be perceived on the level of the architectural pattern of the cancellous bone. However, one could detect at least the image of a growing rupture of the cortex of the alveolar edge; the use of a varying kilovoltages did not influences the appearance, or lack of it, of the bone defects.
