Oral Health Education for Children: Development of a Serious Game with a User-Centered Design Approach

Background: Children can learn efficiently with well-designed serious games. The use of applications to promote health has proliferated, but there is a lack of scientific studies on educational games in oral health.Materials and Methods: We developed the Brazilian version of a British and Jordanian oral health education game for children from the perspectives of Brazilian specialists and users. This descriptive study, with a qualitative and quantitative approach, comprised three phases: I-Experts' discussion of the appropriateness of the previous version of the game to Brazil; II-Development of the first Brazilian version of the game; and III-Evaluation of the first version with 15 children from 4 to 8 years of age.Results: In Phase I, the specialists agreed with the development of the Brazilian version of the game, with minor adjustments on: advice on eating; advice on oral hygiene habits, users' age group, game characters, and game purpose. Phase II: a version with a few changes in images and recommendations, written and spoken in Brazilian Portuguese. Phase III: The global average of correct answers in the game's tasks was 75.3%, ranging from 50.0% to 100%. Children reported having fun with the game, and most understood the content and its interface; their parents found the information relevant and enjoyed the gameplay with their children.Conclusions: The Oral Health Education Game offered basic information for preventing dental caries to Brazilian children aged 4-8 years old in an interactive and fun way; it could support professionals in improving oral health education.
