Abstract

Magnification in PANORAMIC radiographies causes errors in treatment plans. The goal of the present study, conducted in the faculty of Dentistry Islamic Azad University (1382), was to determine the amount of such MAGNIFICATION in PANORAMIC radiographies.To do this descriptive study, sixty samples referred to the radiology department. Were selected sequentially. A standard metallic ball with the diameter of 5mm was placed in the mouth, where as the actual size of the extracted tooth was measured by AACO caliper, at the level of 0.01 mm accuracy. Then, the balls and teeth images, prepared by PANORAMIC RADIOGRAPHY machine: TROPHY model odontorama PC were measured and examined by paired Hest. Following the measurement of the sample size and their images carefully and doing statistical tests, these conclusions were drawn:1- The amount of MAGNIFICATION, in the anterior region, in length was found 42% (P<0.0001) and that of width was 24.8% (P<0.0001).2- In the posterior region, the amount of MAGNIFICATION were 37.48% (P<0.0001) in tooth samples, 39.4% (P<0.0001) in ball samples, and in width 30.55% (P<0.0001) in tooth samples, 29.8% (P<0.0001) in ball samples. It should be mentioned that sex and age do not play any role on the results. Moreover, due to the low MAGNIFICATION difference between ball and tooth samples, the use of ball, to determine the amount of MAGNIFICATION in different region is clinically possible. The above mentioned machine has the following. 1- length of the anterior region2- length of the posterior region 3- width of the posterior region4- width of the anterior regionThus, it is recommended that all images should be prepared by an experienced operator, with a machine of the minimum MAGNIFICATION that the amount of it is explained beside the radiographs.
