Background: Ethics is essential in healthcare, including dentistry, to help dentists do the right things, build trust, and take good care of patients, but even though dentists learn about ethics, they still have some ethical problems, like sharing patient pictures without permission or criticizing other dentists on social media. Teaching ethics practically and interestingly could help them use ethical rules better in their work. Objective: To explain the better teaching mechanism about ethics to dental students, especially when using social media. Methods: Data was expected from dental medicine students at Airlangga University, who were taught ethics using four methods: conventional lectures, group discussions, paper assignments, and creating educational videos. Results: After completing the ethics class, students are expected to apply ethical principles as co-assistant doctors, extending to their use of social media. Conclusion: discussion-based classes significantly prepared dental medicine students for their roles as co-assistant doctors, fostering dynamic idea exchange, critical thinking, and practical application of ethical knowledge, especially when using social media.
