The purpose of this study was to evaluate the measurement error between conventional films, digital cephalographs and hardcopy. The material consisted of 29 cephalographs which used image modality of Asahi CX-90SP in the Kyung Hee University Dental Hospital. One observer measured fiducial measurements at an interval of four weeks. Measurement error was tested by Dahlberg’s formula. A paired t-test was used to detect it between each modality.
The results are as follows;
1. The monitor-displayed digital image showed enlargement compared with the conventional image. The cephalometric measurements of the monitor-displayed digital image and conventional image were no statistically significant difference except SNB.
2. In conventional image, measurement errors of linear and angular measurements were 0.23㎜, 0.36°, respective. In monitor-displayed digital image, measurement errors of linear and angular measurements were 0.63㎜, 0.48°, respective.
3. The reduction ratio of hardcopy was 1.01% compared to the monitor-displayed digital image.
Based on the results, it indicates that the digital cephalographs and hardcopy using storage phosphor digital radiography showed the same accuracy as the conventional films in clinical use.
