Dental Anatomy
Final Test Solutions
Course Introduction
Dental Anatomy is the study of the structure, function, and morphology of the teeth and their surrounding oral tissues. This course provides a foundational understanding of both the macroscopic and microscopic features of human teeth, including their development, eruption patterns, and the variations found among individuals. Students will explore tooth identification, numbering systems, and occlusal relationships, as well as important aspects of dental histology and embryology. Emphasis is placed on the clinical relevance of dental anatomy in diagnosis, treatment planning, and restorative procedures, forming a basis for advanced studies in dentistry.
