Poor oral hygiene can cause severe periodontal disease. Therefore, it is necessary to educate individuals regarding the importance of maintaining good oral hygiene. To this end, in this study, we evaluated the efficacy of using a phase contrast microscope as an instructional tool for oral hygiene. Forty patients, randomly divided into test and control groups, were recruited 6 months after receiving oral prophylaxis. A phase control microscope was used as a demonstration tool for the test group, and a dentiform model was used to demonstrate the ideal tooth-brushing method for the control group. In the test group, awareness regarding the importance of proper oral hygiene was found to increase by 30%, and in the control group, awareness was increased by 20%. The overall satisfaction with the instructional program was 80% in the test and 70% in the control group. The level of understanding was 99% in the test and 80% in the control group. Instructions were easily followed by 80% of the test and 60% of the control group. Understanding of the program was significantly higher in the test group than in the control group (p < 0.05). The overall satisfaction and understanding of proper oral hygiene was over 70% for both the groups. The phase contrast microscope-based instructional program yielded higher actual practice rates. The phase contrast microscope is desirable tool for motivating patients and spreading awareness regarding the importance of maintaining good oral hygiene.

방사광 X-선 현미경은 임상실험에 유용한 도구로 높은 배율과 고 해상도로 동물 장기조직 시료의 세부 구 조를 관찰할 수 있다. X-선 영상은 위상 대조도 메커니즘으로 설명할 수 있다. 우리는 쥐의 꼬리, 신경 및 허파 의 in-vivo 및 in-vitro위상 대조도 영상을 8 KeV mono 빔으로부터 10배 현미경대물렌즈와 CCD 카메라를 이용하여 얻었다. 기존의 흡수 X-선 영상 보다 SR 영상이 세밀한 구조의 높은 분해능 영상을 볼 수 있었다. SR 영상은 생물학, 재료 및 임상 연구에 무한한 가능성을 가지고 있다.
