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 0.23mm, 0.36°, respective. In monitor-displayed digital image, measurement errors of linear and angular measurements were 0.63mm, 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.
Purpose: The aim of this study was to evaluate the patient’s and dentist’s perspective and knowledge on rapid human immunodeficiency virus screening test in dental setting. Material and Methods: In March 2009, 100 patients and 100 dentists at Department of Periodontology, College of Dentistry, Yonsei University were provided an attitude assessment survey. Results: Results were analyzed for acceptance of testing and potential barriers. 94% of patients agreed to take a rapid HIV screening test and 77% of dentists were willing to provide the test to their patients. Also the current knowledge state of patients and dentists on HIV infection was not accurate as expected. Conclusion: Overall, dental clinic patients widely accepted the offer of rapid oral HIV screening. Rapid HIV screening test in the dental setting can be an important option to increase the number of individuals who know their HIV status.
