The Evaluation of Knowledge and Behavior of Medical Doctors about Toothbrush Disinfection

ABSTRACT Objective: The aim of this study was to evaluate the knowledge and behavior of medical doctors about toothbrush disinfection. Methods: This study included 170 medical doctors (63 females, 107 males). Participants filled out the standard questionnaires which contained 18 items into three parts: demographic data, personal oral hygiene practices-patient recommendations about toothbrush disinfection, and toothbrush disinfection. Data analyses were performed with t-tests, chi-squared tests, and Fisher’s exact tests, where appropriate. Results: Regarding personal oral hygiene practices; most medical doctors reported that they brushed their teeth at least twice a day and changed their toothbrushes once every three months. Statistically significant differences were found between females and males for these questions (p < 0.05). Most participants stored their toothbrushes in an open-topped toothbrush holder shared with other individuals and shared their toothpaste with other individuals. The doctors mostly did not any advice their patients about toothbrush usage. Conclusion: Regarding toothbrush disinfection; most medical doctors reported a lack of knowledge about toothbrush disinfection and did not disinfect their own toothbrushes. On the other hand, the participants mostly thought that toothbrush disinfection was necessary for everyone. The results of this study showed that majority of the participants were unaware about the subject.
