Introduction: Toothbrushes are vital to remove dental biofilm and to prevent dental caries and periodontal disease. Repeated use of toothbrushes leads to contamination; hence, disinfection is essential in the maintenance of a brush. Current understanding and perception among dental students about toothbrush contamination and disinfection are essential. Aim: The aim of this study was to assess the perceptions about toothbrush contamination and disinfection among postgraduates and interns in Bengaluru city. Materials and Methods: A cross-sectional study was conducted using self-administered questionnaire among 400 postgraduates and interns from five dental colleges in Bengaluru. The statistics were computed with the Statistical Package of Social Sciences (SPSS) version 22 software and Chi-square test was used. A P < 0.05 was considered statistically significant. Results: There was a statistically significant difference regarding the source of information on tooth brush contamination (P = 0.008) and common mode of transmission of contamination (P = 0.01) between the two groups. The difference was found to be statistically significant (P = 0.01) regarding sharing of toothpaste. Only less than half of the participants, in both the groups practiced disinfection. Conclusion: There was a statistically significant difference in the perceptions about tooth brush contamination and disinfection among postgraduates and interns that might be attributed to their higher academic knowledge and clinical experience.
