2. OVERVIEW
• Endocrine System
• Common Endocrine Diseases
• Risk factors
• Signs and symptoms
• Dental Management & Considerations
3. ENDOCRINE SYSTEM
- Responsible for hormonal secretion
- Diversify it's function through hypothalamus and pituitary
- Controls physiological process and homeostasis
7. 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
8. ENDOCRINE DISEASES:
OSTEOPOROSIS
• Commonly found amongst women
• Causes:
o Lack of intake of Calcium/Vit. D
o Menopause: decreased estrogen level
ENDOCRINE DISEASE:
Osteoporosis
9. RISK FACTORS:

Low Body Weight
Family History
Smoking & High
Alcohol Consumption
RISK FACTORS
ENDOCRINE DISEASE:
Osteoporosis
10. 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
11. • 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:

12. DENTAL CONSIDERATIONS:
OSTEOPOROSIS
• Frequent dental visits

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:

14. • High blood sugar, because pancreas does
not produce enough insulin or cells do
not respond to the insulin.
• Most common endocrine disease in
Singapore
• Prevalence: 11.3% in 2010
• M>F
• Indian 17.2%, Malay 16.6% and Chinese
9.7%

Thyroid gland disorders
ABOUT THE THYROID
Secretes 3 hormones:
䐟 Thyroxine (T4)
䐠 Triiodothyronine (T3)
䐡 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.
27. 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. #
-singhealth
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)
28. CAUSES:
HYPERTHYROIDISM
Other risk factors:
Gender
History
Age
Smoking
Trauma to the
thyroid
Major stress
ENDOCRINE DISEASE:
Thyroid gland disorders
Thyroid
nodules
CAUSES
Thyroiditis
Excessive
iodine
intake
Medications
Graves’
disease
29. 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
ENDOCRINE DISEASE:
Thyroid gland disorders
31. DENTAL CONSIDERATIONS:
HYPERTHYROIDISM
Oral manifestations:
• Enlargement of extraglandular thyroid tissue (mainly in the lateral
posterior tongue)
• Accelerated dental eruption
• Burning mouth syndrome
• Increased susceptibility to caries
• Periodontal disease
• Maxillary or mandibular osteoporosis
• Sjogren's syndrome
• Thyroid may be enlarged or noticeably palpable (Graves’ disease)
Medications:
o anti-thyroid drugs- methimazole, propylthiouracil
o radioactive iodine
o beta-blocker and iodides
ENDOCRINE DISEASE:
Thyroid gland disorders
32. 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
ENDOCRINE DISEASE:
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
Thyroid gland disorders
PATIENT MANAGEMENT:
HYPERTHYROIDISM
34. PATIENT MANAGEMENT:
HYPOTHYROIDISM
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:
Thyroid gland disorders
36. 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
37. Hyperparathyroidism
• Overactivity of the parathroid glands
• Excess production of PTH
• Raised PTH levels are harmful to bone
• Primary hyperparathyroidism / Secondary
hyperparathyroidism
