- The primary subject of study in dental anatomy is the structure and morphology of teeth.
- This field focuses on understanding the detailed shape, size, arrangement, and surface features of each type of tooth.
- Knowledge of dental anatomy is essential for various dental practices such as restorations, orthodontics, and prosthodontics.
- While other topics like the developmental stages of oral mucosa, physiology of salivary glands, and neural innervation of the oral cavity are important in dental sciences, they fall under different specialized areas such as oral histology, physiology, and neuroanatomy respectively.

In summary, dental anatomy primarily deals with the form and features of teeth, which is crucial for proper diagnosis and treatment in dentistry.
