One of the causes of increasing prevalence of dental caries in the community is the lack of role of posyandu cadres in dental health. The purpose of this community service is to revitalize the role of posyandu cadres in Ngagel Rejo Health Center Surabaya with training on dental health. The training method uses problem-based learning, and a 10-hour training time. The calculation of the duration of the training is the number of participants divided by the number of participants and then multiplied by 4 days. After the training, Ngagel Rejo Health Center has 50 posyandu cadres who have been trained on understanding dental health. The training can increase posyandu cadres’ knowledge about dental health.
