Radiation Health & SafetyQuestion 15 of 100
Which group of tissues is considered MOST radiosensitive and therefore of greatest concern during dental radiography?
a.Muscle, nerve, and mature bone
b.Bone marrow, thyroid gland, and the lens of the eye
c.Enamel, dentin, and cementum
d.Tendon, cartilage, and fat
Explanation
Rapidly dividing, undifferentiated tissues such as bone marrow, thyroid tissue, and the lens of the eye are the most radiosensitive and are the critical organs protected during dental imaging. Muscle, nerve, and mature bone are highly differentiated and comparatively resistant. Tooth structures and connective tissues such as tendon, cartilage, and fat are also relatively radioresistant.
