title: [Experimental studies on a periodically reproducible radiologic interpretation in bone transplantations].
abstract: A method of radiologic evaluation using a semiautomatic image analysis device was developed which permits a two-dimensional analysis of bony changes in time intervals. The objective reproducibility of the evaluation was determined in a control group of four patients without signs of periodontal changes. The standard deviation was 7%. The statistical analysis of the subjective range of radiologic interpretation showed a standard deviation of 9.1%. This method of radiologic evaluation was applied to control examinations of 20 patients with bone grafts. It was possible to carry out a percent and an absolute evaluation of the bony changes in time intervals.
