This course uses a seminar format to discuss and develop critical thinking among graduate students in regards to the aetiology, risk assessment, and prevention of oral diseases and conditions. Preventive dentistry aims to maintain and improve the oral health status of individuals and populations. The typical image of preventive dentistry is to prevent dental caries in a patient. However, prevention of dental caries at the individual level only represents one part of preventive dentistry. Preventive dentistry integrates primordial, primary, secondary, tertiary, and quaternary prevention, along with considerations at the individual and population level, including the oral-systemic health link, and involvement of other health and social service providers in the prevention of all oral diseases and conditions. The course is available to all graduate students at the faculty.
