Background: Minimally Invasive Dentistry (MID) is the most modern approach for the management of dental caries. There is limited evidence that whether the familiarity with MID principles imbibed through the curriculum is translated into clinical decision-making and practice. This study was conducted to assess the knowledge, attitude, practice and behaviour of dental interns towards MID. Methods: A cross-sectional survey was conducted in the year 2015 for a period of 3 months among 260 dental interns of 3 dental colleges, Pune city using a self-administered validated questionnaire. In addition to the demographic profile, 28questions focused on knowledge, attitude, practice and behaviour towards MID. The data was analysed using descriptive statistics, Chi- Square test to compare proportion of correct answers and Spearman’s rank correlation to assess relation between knowledge, attitude, practice and their clinical decision behaviour scores. Results: A total of 256 questionnaires were found to be legible with an overall response rate of 98.4%. The mean scores for knowledge (4.19+1.2), attitude (6.60+2.02), practice (22.59+3.83), and clinical decision behaviour (2.88+1.21) showed that these interns had adequate knowledge and a positive attitude toward MID. The mean clinical behaviour score showed a significant correlation with knowledge and practice and even between knowledge and attitude. Conclusion: Though majority of dental interns had inadequate knowledge but they showed a positive attitude towards MID which, to some extent influenced their clinical decision making behaviour and its practical application
