Question 542 · LDEK · Dentin hypersensitivity

A patient reported due to pain located in the teeth 34 and 33, which occurs during brushing and consuming sour drinks. Intra oral examination did not reveal any pathologies although tooth 34 and 33 react with pain to probing the cervical areas. Observed symptoms are most likely related to:

1) the desiccation of tissue fluid in the dental tubules;
2) initiated erosion;
3) presence of initial caries;
4) reaction of sensory fibers which penetrate into the dental tubules;
5) transfer of the odontoblast’s nuclei into the dentine area;
6) pressure change in the peripheral end of dental tubule.
The correct answer is:
  1. A. 1,4,5,6.
  2. B. 1,2,5,6.
  3. C. 1,3,4,5.
  4. D. 2,4,5,6.
  5. E. 1,2,3,4.
Hint

Short, sharp pain on brushing and acid with no visible lesion — eliminate options naming pathology that the examination did not find.
