Introduction: Dental caries is a widespread infectious disease that derives from the colonization of the enamel surface by microorganisms that produce acids, leading to mineral loss. Its clinical manifestation depends on the interaction of different etiological factors. Although it is a subject that is part of the clinical routine of the dentist, knowing the current scientific evidence, as well as the best way to carry out the diagnosis and treatment is crucial for the professional who is concerned not only in interventional clinical practices but also in promoting oral health in the patient. Materials and Methods: In the first part of the survey, data on knowledge, attitudes and skills acquired in the field of Preventive Dentistry were obtained, through the PPKS (this questionnaire has been validated for Portuguese). In a second part, data regarding caries diagnosis and treatment decision and data related to caries associated with restorations/sealants and treatment decision were obtained, using the ICCMS as a tool. Results: The PPKS survey was validated, and the test-retest reliability of the questionnaire was assessed by determining the Cronbach's alpha coefficient (greater than 0.6), which indicates that it has acceptable consistency. Participants did not show relevant differences between groups (students and professors). Despite the time lag in learning and clinical practice, the two groups showed similar knowledge in the field of Preventive Dentistry and Operative Dentistry, considering the current scientific evidence on the subject. Conclusion: It is concluded that the PPKS questionnaire showed reliability to be used in the Portuguese language version. The investigated sample showed a good knowledge about the importance of oral health promotion, and about the current concepts of caries disease in relation to treatment and diagnosis.
