Course Introduction
Dental Sciences is an interdisciplinary field that explores the structure, function, and health of the oral cavity and related tissues. This course provides a comprehensive overview of oral anatomy, physiology, microbiology, pathology, and the principles of disease prevention and treatment. Students will examine the biological mechanisms underlying dental health, study common oral diseases and their management, and learn about current techniques in diagnosis and patient care. Emphasis is placed on the integration of scientific knowledge with clinical practice, preparing students for further study or careers in dentistry, dental hygiene, or related health professions.
