 AB : The purpose of this study is to obtain the horizontal magnification rate of orthopantomography.
 The subjects were consisted of 30 Korean adults who had Angle's classification I occlusion by using measuring wire set on the incisal edges of anterior teeth and the occlusal surfaces of premolars and molars along the dental arch.
 The results are as follows;
 1. The average rate of total magnification was 115%
 2. The average rate of local magnification was that the anterior teeth region was 90%, the canine region was 96%, the p remolar region was 104%, the lst molar region was 117%, and the 2nd molar region was 124%.
