ENDOCRINE DISEASES: OSTEOPOROSIS
• Define Osteoporosis (U.S. National Library of Medicine):
o A disease in which bones become fragile and more likely to fracture.
o Usually the bone loses density, which measures the amount of calcium and minerals in the bone
ENDOCRINE DISEASE:
Osteoporosis
ENDOCRINE DISEASES: OSTEOPOROSIS
• Commonly found amongst women
• Causes:
o Lack of intake of Calcium/Vit. D
o Menopause: decreased estrogen level
ENDOCRINE DISEASE:
Osteoporosis
RISK FACTORS: OSTEOPOROSIS
Low Body Weight
Family History
Smoking & High Alcohol Consumption
RISK FACTORS
ENDOCRINE DISEASE:
Osteoporosis
SYMPTOMS: OSTEOPOROSIS
Early Stages:
• Almost no symptoms
More than often, many will have experienced a fracture before finding out.
Later Stages:
• Pain (Due to compression fractures)
• Loss of height
ENDOCRINE DISEASE:
Osteoporosis
• Assoc. with alveolar bone loss & increased risk of periodontal disease o Weakened bone structure
o Increased risk of alveolar bone resorption, attachment loss, tooth loss and edentulism
• Bisphosphonate therapy o Increased risk of Osteonecrosis after dental extraction
ENDOCRINE DISEASE:
Osteoporosis
DENTAL CONSIDERATIONS: OSTEOPOROSIS
DENTAL CONSIDERATIONS:
OSTEOPOROSIS
• Frequent dental visits o Scaling and Root Planing to prevent progression of
periodontal disease resulting in bone loss
• Denture fit o Ill-fitting dentures
• Susceptible to periodontal bacteria o Increase risk for periodontal diseases and tooth loss
ENDOCRINE DISEASE:

ENDOCRINE DISEASE:
Thyroid gland disorders
ABOUT THE THYROID
Secretes 3 hormones: Thyroxine (T4) Triiodothyronine (T3) Calcitonin- Regulate Ca and phosporus
levels, skeletal remodeling
Thyroid hormones influence the growth and maturation of tissues, energy metabolism and turnover of both cells and nutrients.
Metabolic processes Oxygen use
ENDOCRINE DISEASE:
Thyroid gland disorders
Hypothyroidism and hyperthyroidism are the two most common thyroid disorders in women between the age of 20 and 50, who are also five times more
likely than men to develop thyroid disorders. #
Hyperthyroidism is the condition caused by unregulated production of thyroid hormones. (decrease TSH, increase T3 and T4)
Hypothyroidism is defined by a decrease in thyroid hormone production and thyroid gland function. (increase TSH, decrease T3 and T4)
-singhealth
CAUSES: HYPERTHYROIDISM
Other risk factors:
Gender History
Age Smoking
Trauma to the thyroid
Major stress
ENDOCRINE DISEASE:

Medications
TYPES AND CAUSES:
HYPOTHYROIDISM
1) CRETINISM (CONGENITAL)
• Iodine deficiency • Defective or absent thyroid gland
2) MYXEDEMA (ACQUIRED)
• Hashimoto’s thyroiditis • Treatment of overactive thyroid • Severe iodine deficiency • Pituitary gland disorder • Long -term lithium intake

DENTAL CONSIDERATIONS: HYPERTHYROIDISM
ENDOCRINE DISEASE:
Thyroid gland disorders
ENDOCRINE DISEASE:
Thyroid gland disorders
Our role: Look out for signs and symptoms to aid in early diagnosis. If a suspicion of thyroid disease arises for an undiagnosed patient, all elective dental treatment to put on hold until full medical evaluation.
1. Brief and stress-free appointments
2. NO local anaesthetic with epinephrine and epinephrine impregnated cord for uncontrolled hyperthyroidism
3. Side effects: Propylthiouracil ! agranulocytosis ! Sialolith ! prolonged bleeding due to warfarin
4. Susceptible to infections due to drug side effects
5. Dietary advice: Avoid iodized salt, seafood
PATIENT MANAGEMENT: HYPERTHYROIDISM
Oral manifestations: • Delayed dental eruption • Salivary gland enlargement • Macroglossia • Glossitis (swollen tongue) • Compromised periodontal health- delayed bone formation • Dysgeusia (distortion of taste) • Delayed wound healing
Medications: Synthroid. levothyroxine, armour thyroid
DENTAL CONSIDERATIONS: HYPOTHYROIDISM
ENDOCRINE DISEASE:
Thyroid gland disorders
1. Susceptible to cardiovascular disease (e.g atrial fibrillation) ! Consult primary care provider to seek whether antibiotics
prophylaxis is required
2. Focus on lethargy, may indicate uncontrolled state and a risk for patients and respiratory rate
! possibility of an iatrogenic hyperthyroid state caused by hormone replacement therapy used to treat hypothyroidism
3. Avoid giving depressants, sedatives or narcotic analgesics ! may cause exaggerated response in patients with mild to severe
hypothyroidism

ENDOCRINE DISEASE:
Parathyroid gland disorders Parathyroid glands
• small endocrine glands that produce parathyroid hormone (PTH)
• there are four parathyroid glands usually located behind the thyroid gland
• controls the amount of calcium in the blood and within the bones so that nervous & muscular systems can function properly
• PTH increases blood calcium levels by stimulationg osteoclasts to break down bone, increasing resorption
• PTH increases gastrointestinal calcium absorption by activating Vitamin D
• PTH increases renal absorption of calcium by the kidneys ENDOCRINE DISEASE:
Parathyroid Disorders
Hyperparathyroidism
• Overactivity of the parathroid glands
• Excess production of PTH
• Raised PTH levels are harmful to bone
• Primary hyperparathyroidism / Secondary hyperparathyroidism
