It was a self-directed, unidentified questionnaire and comprised 25 close questions with 4 possible answers. A total of 40 clinical dental students, interns, practicing dentist, dental specialists and academician were recruited using non-probability availability sampling.<br> <strong>Results</strong>: The questionnaire contained questions about personal information (5), knowledge (7), attitudes (6), and practices (6). About 60% of the respondents belonged to 20-30 years while 30% to 31-45 years old group. The participants were 59% undergraduates, 30% postgraduates, 7% academician, and 3.6% academician and private practitioner.
