All of the following statements concerning amelogenesis imperfecta are true
EXCEPT on. Which one is the EXCEPTION?
• It is an inherited condition that is transmitted as a dominant trait
• Because of the enamel malformation, the teeth of individuals with amelogenesis im-
perfecta are often discolored, sensitive to temperature changes, and painful to brush
• It only affects the permanent teeth
• It causes the enamel to be soft and thin
• The teeth appear yellow because the dentin is visible through the thin enamel
• The teeth are easily damaged and susceptible to decay

• Characterized by the appearance of immature, abnormal cells in the bone marrow
and peripheral blood and frequently in the liver, spleen, lymph nodes, and other
parenchymatous organs
• Marked by the effects of anemia, which are usually severe (fatigue, malaise), an
absence of functioning granulocytes (prone to infection and inflammation), and
thrombocytopenia (hemorrhagic diathesis)

You have a dental patient who mentions during his health history that he
has an “overactive thyroid.” You ask him about his medications and he states
that he doesn’t know what he takes now, but at one time he took methima-
