Study Notes
Oral Mucosa
- Oral mucosa is the soft tissue lining of the mouth, covering the lips, cheeks, and the floor of the mouth.
- It acts as a barrier protecting underlying tissues from external forces and provides sensory receptors for pain, touch, temperature, and taste.
- Oral mucosa is lubricated by saliva which helps with swallowing, reducing trauma, and providing a protective reflex.
Types of Oral Mucosa
-
Lining Mucosa: Found in areas of the mouth that are subjected to less mechanical stress, like the inner cheeks, floor of the mouth, and ventral surface of the tongue.
- Appears soft, moist, and stretchable.
- Histologically, it is non-keratinized stratified squamous epithelium.
- Surgical incisions in this area often require sutures due to its softness.
- Local anesthetic injections are easier and less discomforting in this area
- Infection can spread rapidly in this area due to its thinness and softness.
-
Masticaory Mucosa: Found in areas of the mouth subjected to more mechanical stress, like the hard palate and gingiva.
- Appears firm, rubbery, and resilient.
- Histologically, it is keratinized stratified squamous epithelium.
- Sutures are rarely needed after surgical procedures in this area due to its resilience.
- Local anesthetic injections are more difficult and cause greater discomfort due to its dense structure.
- Swellings in this area from infections are more uncomfortable due to its denseness.
-
Specialized Mucosa: Found in areas specifically designed for sensory functions, especially taste buds on the dorsal surface of the tongue.
- Appears as a specialized structure, not as a surface texture.
- Histologically, it is keratinized stratified squamous epithelium with specialized structures like taste buds.
Changes in Appearance
-
Hyperkeratinization: Nonkeratinized epithelium can transform into a keratinizing type in response to friction or chemical trauma.
- It appears clinically as a white area, sometimes with an irregular red border.
- It can be reversible if the causative trauma is removed.
-
Oral Pigmentation:
- Can be caused by aging, drugs, infections, or self-inflicted tattoos.
- Pigmentation can be caused by certain drugs like chemotherapy and infection by the Human Papilloma Virus (HPV)
