PURPOSE: This study aimed to investigate students’ cheating behaviors, perceptions, and risk factors for cheating. METHODS: The author conducted a questionnaire survey of 375 undergraduate students at the Dankook University College of Dentistry in 2017. The questionnaires consisted of three parts: individual information, a moral sensitivity test, and cheating behaviors. Students rated whether they were involved in 28 cheating behaviors and their intolerant attitude for each behavior. Each student received a cheating grade of severity and diversity from 0 to 4 according to the degree of commitment in cheating behaviors. Chi-square and correlation tests were performed among cheating grades, individual factors, and moral sensitivity. RESULTS: Most students admitted having engaged in at least one cheating behavior (92.2%). School years, intolerant attitudes towards cheating, perceived prevalence, study time, and academic performance showed significant correlations with students’ cheating grades. CONCLUSION: These findings indicated that cheating behaviors were a very serious and prevalent problem at this dental college in South Korea. This is a critical issue that must be addressed. Dental school faculty members need to work together to develop policies, ethics curriculum and to improve students’ attitudes. It is also important to encourage students to learn and devote their time to study to reduce cheating behaviors.

When we think about ethics or morals, we tend to look at them from the viewpoint of here and now. Actual implications of then and there, however, could be different. That is why we should study history of bio-ethics along with philosophy involved in it. Bio-medical ethics is situated in spatial and cultural dimension as well as temporal and historical. Dentistry has been in a peculiar situation in that although it has evolved from the same root as medicine it has become separate discipline. Ethical implications of dentistry, however, share the historical and philosophical background with its mother discipline, i.e., medicine, surgery, barber-surgery and even smithery. This paper tries to grasp the main ideas of bio-medical ethics from the ancient Greek and China and picks up three of them as guiding principles, i.e., deontology and teleology from the west and self-cultivation from the east, It also tracks down the contents of modern biomedical ethics; from etiquette to ethics, from morals to contract (ethics of autonomy), and ethics of professional responsibility. Finally it reviews and analyzes two different traditions of dental professional regulation from the legal and ethical point of view (U.S. and Europe), and proposes a new direction for the construction of dental ethics in Korea.

OBJECTIVES: This study aimed to measure the efficacy of different tooth-brushing methods for removing plaque in Korea. METHODS: This study was conducted with the approval of the Institutional Review Board (IRB) of the Seoul National University School of Dentistry (S-D20180021). Thirty participants aged between 19 and 30 years, who did not have periodontal disease, were enrolled in this observational study. Participants were given the same type of toothbrush and toothpaste and asked to brush their teeth as they usually would. During brushing, participants were recorded with a camcorder that was attached to a mirror. Participants were aware they were being recorded. After they had finished brushing their teeth, a dental plaque staining and oral plaque index (PI) examination was performed. The PI score was measured using the Turesky modified Quigley Hein Index. Brushing methods were classified as rolling, horizontal, vertical, circling, and oblique. Skipped surfaces were recorded separately. Following this, statistical analysis was performed using SPSS software. RESULTS: Most surfaces of the mouth were skipped. The most commonly used brushing method was the circling method, followed by the vertical, horizontal, rolling, and oblique methods. The most frequently used method on the vestibular surface was circling, with 52.92% of the oral surface skipped. The oblique brushing method had the lowest mean PI score with a mean±SD of 1.73±0.82. The mean PI score of the skipped surfaces was the highest with a mean±SD of 2.52±0.81. We also analyzed the linear mixed model considering the different lengths of time spent brushing. Both the brushing method used and the time spent brushing had a significant effect on the PI score, but no interactions between these were observed. In areas where a horizontal brushing method had been used, the PI score was significantly decreased. CONCLUSIONS: This study suggests that the horizontal brushing method is an efficient tooth-brushing method compared to the other methods. Additionally, tooth-brushing for more than 10 seconds on 3 to 4 teeth area was effective in removing dental biofilm.
