Study Notes
Oral Mucosa
- The oral mucosa is a protective lining in the oral cavity.
- It plays multiple roles - protection, secretion, sensation.
- The oral mucosa comes in three types: lining, masticatory and specialized.
Lining Mucosa
- Covers the buccal mucosa, labial mucosa, alveolar mucosa, floor of the mouth, ventral surface of the tongue and soft palate.
- The lining mucosa is softer, moist, and more able to stretch and compress, acting as a cushion.
- Lining mucosa has non-keratinized stratified squamous epithelium.
- Local anaesthetic injections in this area are easier and less painful.
- Infections can spread rapidly in this area.
Masticatory Mucosa
- Covers the attached gingiva, hard palate and dorsum of the tongue.
- Masticatory mucosa is firm, with a rubbery texture.
- Masticatory mucosa has keratinized stratified squamous epithelium
- Local anaesthetic injections in this area are more difficult and more painful.
- Swelling in these tissues due to infection is more uncomfortable.
Specialized Mucosa
- It consists of lingual papillae.
- Specialized mucosa is mostly associated with keratinized epithelium.
Changes in Appearance
- Hyperkeratinization occurs when non-keratinized epithelium transforms to a keratinizing type due to trauma, resulting in a keratin and granular layer.
- Oral Pigmentation is a change in color in the oral mucosa, appearing as brown to brownish-black flat areas, often occurring as the tissue ages.
