Mind mapping is a powerful tool. It has been used to summarize information on concepts, assess understanding, and reflect upon the learning process by enabling the visualization of change in student understanding in qualitative and quantitative ways. Mind mapping provides an integrated mixed method that can be used to open a dialog between teaching and learning. Using this tool, we planned to assess the ability to express the decision-making of the procedure -“Extraction of tooth”. This involves three parts- Pre-evaluation, Local anesthesia technique, and extraction procedure. For example, in the local anesthesia part- solution to be used; technique; nerve involved; anatomical landmarks, and so on. This is a part of problem-based learning (PBL). Hence, this educational research was planned with.

To assess the ability to express the decision-making of undergraduate dental students for procedural skills of oral surgery using a mind map.

The mean score after the first exercise [AFE] the LAME- Local anesthesia mind map exercise was 59.19 and after second exercise [ASE] was 146.08, and this difference in mean scores was statistically significant.

The mean score AFE tooth extraction mind map exercise (TEME) was 85.88 and ASE of mindmap for the tooth extraction exercise was 160.13 and this difference in mean scores was statistically significant.

Mind Mapping Tool (MMT) is an effective tool to teach clinical reasoning, and promote knowledge organization and critical thinking. The postgraduates can also use MMT for the integration of clinical concepts and listing of procedural steps.
