Course Introduction
Dental Sciences is an interdisciplinary field that explores the structure, function, and diseases of the teeth, gums, and related oral tissues. This course offers a comprehensive overview of oral biology, dental anatomy, pathology, and preventive dentistry, along with an introduction to clinical procedures and techniques used in the diagnosis and treatment of oral health conditions. Emphasizing both theoretical foundations and practical applications, the course integrates knowledge from biomedical sciences with evidence-based dental practices, preparing students for further study or careers in dental medicine, dental hygiene, or related healthcare fields.
