I n the medical world, every action will always be closely related with ethics and laws which are constantly changing and evolving as the time goes by. However it is unfortunate to see the lack of attention given by health personnel upon understanding those subjects, especially about medical confidentiality. Along with technology advancement, the knowledge regarding medical world is easier to obtain by the patients, thus the lack of studies and understanding upon the topic of medical ethics and laws may disadvantages the prospective dentists, such as not knowing the limit of what may and may not be done, and the consequences that may be faced when violating medical confidentiality. This research is conducted as a descriptive observational study that aims to discover the perception of dental students, especially those who will soon become a young dentist, regarding medical confidentiality. Among 207 students from generation of class year 2013, 100 students were appointed as respondents. The research result obtained from asking 10 out of 15 questions shows that most respondents have a perception that conforms to medical ethic standards to the patient and in accordance with applicable law, however in five other questions, more than half of the respondents don't have enough knowledge to give the perception that a dentist candidate should have, which may be caused by the lack of learning the corresponding topic. This research expects to give more attention the study about perception of medical ethic subjects, especially on the topic of medical confidentiality.
