Study Notes
Importance of Oral Cavity Knowledge
- Dental professionals play a crucial role in improving patient health.
- Understanding the oral cavity and pharynx is vital for recognizing clinical conditions.
Anatomic Position
- Textbook illustrations depict the head in an anatomic position for precise reference.
Oral Cavity Divisions
- The oral cavity encompasses vestibules, dental arches, teeth, and the oral cavity proper, each with unique landmarks.
- Anterior boundary marked by lips; posterior boundary defined by the pharynx (throat).
Jaws and Alveolar Processes
- Maxilla consists of two immobile, fused maxillary bones.
- Mandible is a single bone with a mobile joint, allowing movement.
- Alveolar processes are the bony extensions housing tooth sockets (alveoli).
- Mature teeth feature both a crown and root structure.
Tooth Structure
- The crown comprises an outer layer of enamel (hard, white) and an inner layer of dentin (moderately hard, yellow) encasing the pulp (soft, pink).
- Roots consist of dental pulp covered by dentin.
Palate
- The palate divides the oral cavity from the nasal cavity, featuring a hard anterior portion and a softer, more flexible posterior portion.
- Incisive papilla is a prominent bulge at the anterior hard palate; palatine rugae are irregular ridges radiating from it.
- Median palatine raphe is a ridge extending from the incisive papilla to the uvula.
Palatal Torus
- A palatal torus may appear at the midline and can impact prosthetic considerations.
Tongue Anatomy
- The tongue is the most prominent feature of the oral cavity.
- Posterior one-third is the pharyngeal part, while the anterior two-thirds form the body.
- Apex refers to the tip of the tongue; the dorsal surface has a median lingual sulcus.
Lingual Structures
- Lingual papillae, present on tongue surfaces, are associated with taste buds.
- Lingual tonsil is located at the dorsal surface's base and should not be confused with palatine tonsils.
- Foliate lingual papilla appear on the lateral surfaces of the tongue.
Ventral Surface of Tongue
- The underside features deep lingual veins, with lateral plica fimbriata showing fringelike projections.
Floor of the Mouth
- Inferior to the tongue in the oral cavity proper.
- The lingual frenum is a midline fold of tissue connecting the tongue to the floor.
- Sublingual folds are tissue ridges on either side of the floor, forming a V-shape towards the tongue's base.
