ABSTRACT
PURPOSE:
To evaluate the magnification error percentage in repeatedly taken panoramic radiographs of same patient and machine. MATERIALS ANDMETHODS:
92 panoramic radiographs from 46 patients were traced and 30 horizontal and vertical measurements were made with digital sliding caliper. The results were compared with paired t-test.RESULTS:
There was no statistically significant difference between the two measurements. The overall difference as percentage error was 6.19+/-5.60%. The largest error as 14.61+/-12.44% was found at condylar height 1, and smallest as 1.86+/-1.61% at mandibular height. Overall vertical error excluding condylar height 1 was 3.76+/-3.97%, and the horizontal error 6.88+/-5.92%.CONCLUSION:
Repeatedly taken panoramic radiographs of the same patient and machine was reliable since there was no significant percentage error difference but the percentage error ranged from 1.86+/-1.61% to 14.61+/-12.44% indicating the error depends on the measuring site.
