Abstract
Radiographs of a model simulating several degrees of [human] alveolar bone height were taken at different vertical projection angles. Bone height was measured by 3 examiners utilizing a projection technique. Correlation coefficients of inter- and intra-examiner readings were statistically significant. The 95% confidence interval of the mean deviation between the observed bone height and the true bone height was < 5.5%. Further investigations are planned to determine whether this method of quantitating the information of radiographs exposed under various conditions is applicable in clinical practice.
