Study Notes
Endocrine Disorders
- The endocrine system comprises integrated glands and cells secreting hormones.
- Hormone secretion is regulated by feedback mechanisms.
- Hormone levels in the blood trigger mechanisms that control hormone production.
- Diseases arise from either too much or too little hormone production.
Hyperpituitarism
- Excessive hormone production originates from the anterior pituitary gland, frequently due to a benign pituitary tumor (adenoma).
- Growth hormone overproduction before bone closure leads to gigantism.
- Overproduction during adulthood results in acromegaly.
- Symptoms include poor vision, light sensitivity, enlarged hands/feet, and increased rib size.
- Facial changes: maxilla and mandible enlargement causing tooth separation and malocclusion; frontal bossing and enlarged nasal bones leading to voice deepening.
- Mucosal changes: thickened lips and macroglossia.
Diagnosis and Treatment of Hyperpituitarism
- Diagnosis entails measuring growth hormone levels.
- Treatment typically involves pituitary gland surgery.
Hyperthyroidism (Thyrotoxicosis)
- Excess thyroid hormone production is more prevalent in women.
- Graves' disease, an autoimmune condition, is a frequent cause.
- Another cause is the over-stimulation of the thyroid gland due to hyperplasia (overgrowth) or the presence of benign/malignant tumors.
Clinical Features of Hyperthyroidism
- Rosy complexion, hand erythema, excessive sweating, fine hair, and softened nails.
- Possible exophthalmos (bulging eyes).
- Patients may also experience anxiety, weakness, restlessness, and cardiac issues.
Oral Manifestations of Hyperthyroidism
- Premature exfoliation of deciduous teeth in children.
- Premature eruption of permanent teeth.
- Accelerated caries and periodontal disease.
- Potential burning tongue sensations.
- Increased risk for connective tissue diseases such as Sjogren's syndrome or SLE.
Treatment of Hyperthyroidism
- Treatments may include surgery, medications to suppress thyroid activity, or radioactive iodine administration.
Hypothyroidism
- Lowered thyroid hormone output.
- Causes span from developmental abnormalities, autoimmune issues, and iodine deficiency to drug-related or pituitary gland problems.
- Cretinism: hypothyroidism onset in infancy/childhood.
- Myxedema: hypothyroidism onset in older children/adults.
- Oral manifestations: thickened lips, enlarged tongue, and delayed tooth eruption in infants; enlarged tongue in adults.
- Other oral manifestations: enamel hypoplasia in both dentitions, anterior open bite, macroglossia, micrognathia, thick lips, dysgeusia, and mouth breathing in patients.
Dental Management in Hypothyroidism
- Requires medical consultation due to potential complications.
Hyperparathyroidism
- Excessive parathyroid hormone secretion from the parathyroid glands, situated close to the thyroid.
- Parathyroid hormone controls calcium and phosphorus metabolism.
- Hyperparathyroidism is characterized by elevated blood calcium (hypercalcemia) and lowered blood phosphorus (hypophosphatemia).
- Can result from hyperplasia, benign/malignant tumor of parathyroid gland(s).
- More prevalent in middle-aged women.
Clinical Features of Hyperparathyroidism
- Mild cases may be asymptomatic or present with joint pain/stiffness.
- Severe cases may cause lethargy and coma.
Oral Manifestations of Hyperparathyroidism
- Well-defined unilocular or multilocular radiolucencies (microscopically, central giant cell granulomas).
- Bone may exhibit a mottled appearance.
- Potential dental abnormalities include widened pulp chambers, developmental defects during dental eruption, weak teeth and malocclusions.
- Loss of bone density.
- Soft tissue calcifications.
Diagnosis and Treatment of Hyperparathyroidism
- Diagnosis involves measuring parathyroid hormone and related blood measurements (like calcium and phosphorus).
- Treatment involves addressing the cause, which may consist of tumors, kidney diseases, or vitamin D deficiency.
Diabetes Mellitus
- Chronic disorder of carbohydrate metabolism resulting in abnormally high blood glucose levels.
- Caused by insufficient insulin, ineffective insulin action, or increased insulin resistance (possibly due to obesity).
- Glucose normally stimulates insulin release from pancreatic beta cells.
- Insulin facilitates glucose uptake by fat and muscle tissues for energy.
Diabetes Mellitus (Type 1)
- Autoimmune disease destroying insulin-producing beta cells.
- Impacts 3-5% of diabetics.
- Can manifest at any age, peaking in the 20s.
- Rapid-onset symptoms: Polydipsia (excessive thirst), polyuria (excessive urination), polyphagia (excessive eating), and possible weight loss, despite increased appetite.
- Requires lifelong insulin therapy.
Diabetes Mellitus (Type 2)
- Characterized by insulin resistance.
- Represents 95% of diabetic cases.
- Commonly develops in adults (35-40 years and older).
- Often associated with obesity, which reduces receptor sensitivity to insulin.
- Diet and weight management can often control symptoms; some require oral hypoglycemic agents.
- Gradual symptom onset.
Risk Factors for Type 2 Diabetes
- Age (over 45)
- Family history (parent, sibling with diabetes)
- Gestational diabetes/large babies at birth.
- Heart disease
- High cholesterol
- Obesity
- Lack of exercise
- Polycystic ovary syndrome (women)
- Previous impaired glucose tolerance
Clinical Features of Non-Insulin-Dependent Diabetes Mellitus
- Atherosclerosis can affect blood vessel walls leading to impaired circulation and oxygenation to tissues.
- Potential for gangrene, high blood pressure, kidney failure, and stroke.
- Diabetic retinopathy potentially causing blindness.
- Potential nervous system damage and increased infection susceptibility.
Oral Complications of Non-Insulin-Dependent Diabetes Mellitus
- Increased prevalence of oral candidiasis (yeast infection).
- Rare risk of mucormycosis (rare fungal infection).
- Bilateral asymptomatic parotid gland enlargement.
- Xerostomia (dry mouth).
- Accentuated response to plaque.
- Slow-healing injuries.
Symptoms of Diabetes
- Type 1: rapid symptom onset (fatigue, increased thirst, etc.)
- Type 2: gradual symptom onset (blurred vision, fatigue, etc.)
Main Oral Health Problems associated with Diabetes
- Increased risk for gingivitis and periodontitis.
- Susceptibility to infections and slow wound healing.
Other Oral Problems associated with Diabetes
- Thrush (oral yeast infection)
- Dry mouth and potential lesions (ulcers)
- Cavities.
- Enlarged/inflamed gums.
Oral Complications of Diabetes (cont.)
- Altered oral flora (changes in bacteria).
- Increased caries rate.
- Salivary dysfunction.
Periodontal Disease (Diabetes)
- Increased prevalence of periodontal disease in uncontrolled diabetes.
- Reduced healing in poorly managed diabetes.
- Periodontal management can contribute to better glycemic control.
Salivary Dysfunction & Xerostomia (Diabetes)
- Dry mouth (xerostomia) from decreased salivary gland function.
- Role of saliva: digestion, oral health maintenance, avoiding decay), and potential damage to salivary glands from neuropathy.
Dental Caries (Diabetes)
- Increased prevalence of dental caries due to salivary hyperglycemia.
Oral Candidiasis (Diabetes)
- Opportunistic fungal infection is increased with hyperglycemia.
- Salivary dysfunction compromises immune function.
- Increased salivary glucose is a growth substrate for fungi.
Burning Mouth Syndrome (Diabetes)
- Chronic burning pain in the mouth of undetermined origin.
- Potentially impacts tongue, gums, lips, and other oral areas.
Patient Management: Diabetes Mellitus
- Regular appointments, including early morning dental visits, are crucial.
- Post-operative care should include antimicrobial/antibiotic therapy after dental procedures.
- Avoiding smoking is crucial for wound healing.
Addison's Disease
- Chronic insufficiency of the adrenal cortex.
- Initial symptoms include increasing pigmentation of exposed skin areas (face, hands), sometimes appearing as light brown or bronze discoloration.
Addison's Disease (cont.)
- Common symptoms include fatigue, lightheadedness, especially when standing, muscular weakness, fever, and weight loss; difficulty standing; anxiety, nausea, vomiting and/or diarrhea/headache/sweating.
- Spot or stripes on the mucous membrane areas (inside of mouth; palate; gums).
Addison's Disease (cont.)
- Differentiated from the following similar ailments: multiple melanotic macules, smoker's melanosis, Peutz-Jeghers syndrome, heavy metal poisoning, post-inflammatory hyperpigmentation, and congenital oral pigmentation.
Addison's Disease (cont.)
- Treatment: Replacing insufficient cortisol (hydrocortisone) and aldosterone.
- Prognosis: Excellent with appropriate treatment.
- Untreated, or poorly managed, cases may result in an Addisonian crisis.
Pre- and Post-operative Considerations for Steroid-Dependent Patients
- Specific dose adjustments for steroids (hydrocortisone) are needed before, and for a period after, dental procedures.
