FIELD: stomatology; applicable in diagnosis with the help of X-ray examination of mouth and teeth. SUBSTANCE: method for comparison of stomatologic roentgenograms is based on the analysis of the image density of the same section of roentgenograms taken at some time interval. The method differs from the known ones in that the field density of each roentgenogram is measured and density values obtained by subtraction from the density of the investigated section, of the density of roentgenogram field. EFFECT: higher accuracy of results of comparative analysis of stomatologic roentgenograms and excluded subjective estimation of results. |
