Due to the high failure rate in the procedure of applying dental anesthesia, this work presents the gamification process of a simulator of this procedure and its validation. From the literature review and simulator analysis, game elements were listed and implemented. The serious game aims to promote a learning strategy that is more attractive, encouraging and allows training evaluation. Partial results of an experiment performed by volunteers indicate that the gamification process was successful and that the game can be submitted for validation with Dentistry professionals.
