Objective: Time and again, it has been shown that active learning promotes critical thinking, and this environment has to be fostered in dental education too. Therefore, the present study was carried out with an aim to know the effectiveness of case-based learning (CBL) in enhancing the knowledge of dental interns of a dental institute in India. Materials and Methods: This pre-post single-blinded, experimental study was conducted in two sessions on a purposive sample of 45 dental interns who gave informed consent. The interns answered a pretest questionnaire comprising questions related to their knowledge of hyperplastic tissue in complete denture patients. The interns were randomly allocated into three subgroups for thorough discussion. Each group viewed all three parts of a case related to hyperplastic tissue and presented the case in the presence of a facilitator. The facilitator discussed the subject with the three subgroups. A post-test was conducted immediately, and the results were compared with the pretest. The facilitator explained about hyperplastic tissue with an audio-visual aid after the post-test was administered. The perception of interns toward CBL was assessed by a standard questionnaire. Results: On analysis, the comparison of the overall knowledge scores pre- and post-CBL showed a statistically significant increase from 9.8 ± 2.14 to 12.6 ± 1.37 (P < 0.001). Conclusion: CBL proved to be effective in enhancing the knowledge of dental interns.
