Preventive Dentistry Test Bank
Course Introduction
Preventive Dentistry is a foundational course that explores the methods and strategies used to avert the onset and progression of oral diseases. It emphasizes the principles of prevention, including dental health education, the use of fluorides, dietary counseling, oral hygiene techniques, and sealants. Students learn to assess individual and community risk factors, develop preventive care plans, and apply evidence-based practices to reduce the incidence of dental caries, periodontal diseases, and other oral conditions. The course also covers the roles of dental professionals in promoting oral health and the integration of preventive services into clinical practice.
