    Biology of the mouth

    Oral epithelium:

    - keratinised: masticatory mucosa (hard

    palate, gingiva and post tongue)- non-keratinised: lining mucosa (buccal,

    labial, alveolar, floor of the mouth, ventral

    tongue and soft palate)- Specialised: dorsum of tongue. Taste.

    Biology - Immunity

    Mechanical: movement of tissue, speech,

    salivation (Xerostomia)

    Saliva: enzymes, mucin GALT: B-cell and IgA

    Cellular: Neutrophils and others WBC. If

    abnormal: inf ulcers, periodontal diseaseand gingivitis
