Thyrotoxicosis
Osteoporosis involving the alveolar bone may
occur, and dental caries and periodontal disease
appear rapidly in these patients. The teeth and
jaws develop rapidly, and premature loss of
deciduous teeth with early eruption of
permanent teeth is common. Euthyroid infants
of hyperthyroid mothers have been reported to
have erupted teeth at birth. A few patients with
thyrotoxicosis have been found to have a
lingual “thyroid,” consisting of thyroid tissue
below the area of the foramen cecum. [34] [35]
If the dentist detects a lingual tumor in a
euthyroid patient, a physician should examine
the patient before the mass is surgically
removed ( Figure 17-16 ). This usually is done
with radioactive iodine scanning. [34] [38]
