Study Notes
Dental Terminology (Anatomy of the Oral Cavity)
- Dentistry is the branch of medicine dealing with the study, diagnosis, prevention, and treatment of oral cavity diseases and disorders.
- Dentists are doctors who practice dentistry.
- Dental supporting team members include dental assistants, dental technicians, and dental hygienists
Anatomy of the Oral Cavity
-
Skull Bone:
- Maxilla: the bone forming the upper jaw
- Mandible: the bone forming the lower jaw
-
Alveolar Bone:
- Part of the mandibular and maxillary bone that surrounds teeth, forming tooth sockets.
-
Tooth Anatomy:
- Crown: the visible part of the tooth
- Root: the part of the tooth embedded in the jawbone
- Pulp: the soft tissue inside the tooth
- Enamel: the hard outer covering of the tooth
- Dentin: the hard layer beneath the enamel
- Cementum: the covering of the root, containing periodontal membrane, nerves, and blood vessels
- Gums (Gingiva): tissue surrounding and protecting teeth and underlying bone
-
Oral Cavity Structures:
- Oral Vestibule: the space between the soft tissues(lips and cheeks) and the teeth.
- Oral Cavity Proper: the region medial to the teeth, including the hard palate, mobile tongue, and floor of the mouth.
- Frenum: tissue attaching gums to lips or cheeks.
-
Tongue:
- Apex: the tip of the tongue
- Dorsal Surface: the top surface of the tongue
- Lateral Surface: the sides of the tongue
- Ventral Surface: the underside of the tongue
- The Floor of the Mouth: the base of the oral cavity, containing glands, nerves, and vessels underneath.
-
Palate:
- Hard Palate: bony part of the roof of the mouth.
- Soft Palate: muscular part of the roof of the mouth.
- Uvula: the fleshy, dangling tissue at the back of the soft palate.
- Hard Palate separates the nasal cavity and oral cavity
- Soft Palate effectively closes the communication from the oropharynx to the nasopharynx during swallowing.
-
Teeth:
- Primary Teeth (Deciduous): the first teeth to erupt (20 teeth)
- Permanent Teeth: teeth that erupt after the primary teeth are lost (32 teeth, 16 in maxilla, 16 in mandible)
