Teachers over 40 years and with children are more likely to have satisfactory knowledge regarding oral health and 88.6% of these professionals have already conducted some activity related to the theme. Conclusion:Although most teachers have done oral health activities, the level of knowledge of teachers about the etiology of caries and periodontal disease was considered unsatisfactory, therefore further clarification in oral health is need so that teachers could act as agents in oral health promotion
