Study Notes
Oral Medicine - Dry Mouth and Salivation Disorders
- Saliva is crucial for oral health, aiding eating, taste, lubrication, and protection. Its composition includes water, mucins, and protective proteins.
- Hyposalivation (reduced saliva) and altered salivary composition lead to dry mouth (xerostomia).
- Common causes of dry mouth include inadequate fluid intake, excess fluid loss (e.g., diabetes), medications (anticholinergics, sympathomimetics, diuretics), and head/neck irradiation.
- Reduced saliva can lead to problems like dental caries, oral infections, and difficulty with eating, swallowing, and speaking.
- Physiological causes of hyposalivation include anxiety (sympathetic activity), mouth breathing, and advanced age.
- Systemic diseases like Sjögren's syndrome, sarcoidosis, and HIV can cause salivary gland dysfunction.
- Dry mouth can also have a psychogenic cause.
Causes of Dry Mouth
- Iatrogenic: Medications are a significant cause, particularly those with anticholinergic, sympathomimetic, or diuretic effects.
- Radiation: Radiation therapy for head and neck cancers often causes hyposalivation.
- Dehydration: Conditions like diabetes, renal failure, and fevers can result in decreased saliva production.
- Salivary Gland Diseases: Conditions impacting the salivary glands (e.g., Sjögren's syndrome, sarcoidosis) can disrupt saliva flow.
- Other Medical Conditions: HIV, hepatitis C, liver diseases, and cystic fibrosis are additionally linked to hyposalivation.
Clinical Features of Hyposalivation
- Difficulties with swallowing (particularly dry foods), controlling dentures, and speaking.
- Unpleasant taste, sense of taste loss, or bad breath.
- Dryness of other oral mucosa, eyes, and potentially other areas.
- Characteristics like adhered lips, dental mirror sticking to the mucosa, missing saliva pooling, dry tongue and potential lobulation/loss of papillae.
- Dental caries, notably in areas not usually prone to them, and recurring cavities are complications.
Dry Mouth (Xerostomia) Diagnosis
- Diagnosis is primarily clinical, based on patient history and examination.
- Salivary function studies like sialometry (measuring salivary flow rate) can aid in diagnosis, though it can be inaccurate.
- Specialist investigation may be needed to assess potential underlying conditions (e.g., connective tissue disorders, systemic diseases).
Sjögren's Syndrome
- Sjögren's syndrome (SS) is an autoimmune disease.
- SS is frequently associated with dry mouth and dry eyes.
- Systemic features, including joint pain, may accompany SS.
- Diagnostic tools for SS include blood tests (autoantibodies), eye examinations (Schirmer test), salivary gland biopsies, and imaging.
Managing Hyposalivation
- Addressing underlying causes is crucial (e.g., stopping/modifying dry mouth-inducing medications, treating other medical conditions).
- Promoting oral hydration and avoiding stimuli that worsen symptoms.
- Using salivary substitutes (e.g., synthetic saliva, water) and stimulating salivation through sugar-free chewing gum/sweets can be helpful.
- Maintaining thorough oral hygiene to mitigate dental caries risk.
