Question 354 · LDEK · Non-carious lesions of dental hard tissues

A pregnant woman in the fifteenth week of pregnancy presented to the dental office because of significant hypersensitivity of teeth occurring especially in response to thermal stimuli. On clinical examination a focal loss of enamel with thin borders was noted and the defective surface was very smooth and looked as if it was polished. The lesions were present on palatal surfaces of upper teeth and buccal and occlusal surfaces of lower teeth. What diagnosis should be considered in this case?

  1. A. erosion.
  2. B. caries.
  3. C. abrasion.
  4. D. abfraction.
  5. E. enamel hypoplasia.
Hint

Smooth, polished-looking lesions without plaque on the palatal surfaces of a pregnant patient suggest a chemical process with no bacteria involved.
