Orofacial Anatomy
Exam Materials
Course Introduction
Orofacial Anatomy is a foundational course that explores the structure and function of the oral and facial regions, with emphasis on the morphology of teeth, bones, muscles, nerves, blood supply, and other anatomical features relevant to dental practice. Students will gain a comprehensive understanding of the anatomical relationships within the head and neck, essential for clinical assessment, diagnosis, and treatment planning in dentistry. The course integrates lecture content with hands-on laboratory experiences, enabling students to identify anatomical landmarks and appreciate the clinical significance of orofacial structures in health and disease.
