With adequate oral health knowledge, dental medicine students can act as role models for their patients in improving the oral health condition for the general population. We know that except using dental brush and tooth paste there are a lot of other additional supplements. The aim of this research was to assess the usage of these additional supplements among the students of dental medicine. For realizing the aim a questionnaire with adequate questions was made. The questionnaire was answered by total number of 137 dental medicine students at our university. Results showed that 74.25 % from the students use additional supplements. Most of them, 66.26% use dental floss, 16.12% of them use interdental brushes, and just 8.2 % use both of them. 67.64 % from the students are using mouthwash solutions. Most of the students that use mouthwash solution also use interdental brushes or dental floss. We can conclude that more than a two-third of the students are using additional supplements for maintaining adequate oral hygiene. This is very important because most of them will be dental professionals in the future, so they can help educating their patients maintaining their adequate oral hygiene
