Theory II - Dentinal Hypersensitivity, Demineralization,
Remineralization, and Fluoride
Questions and Answers 2024
1. What is the most accepted mechanism of dentinal hypersensitivity?: Hydro- dynamic Theory
(fluid movement)
2. When the exposed dentin surface is subjected to stimuli, the fluid flow within the dentin
tubules .......: will be increased
3. Approximately 75% of patients with dentinal hypersensitivity complain of pain with application of
: cold stimuli
4. The and the of the dentin tubules are con- sidered
important factors in initiating pain from dentinal hypersensitivity: 1) number
2) diameter
5. stimuli that trigger pain in dentin hypersensitivity: - Thermal
- Mechanical (tactile)
- Osmotic
- Evaporation
- Chemical
6. What are the causes of dentin exposure?: 1) recession
2) attrition
3) abrasion
4) erosion
5) abfraction
7. Why do patients experience post-debridement sensitivity?: calculus provides a protective coating
to shield exposed dentin from stimuli
8. Enamel that has been damaged by abfraction is more likely to be affected by : erosion or
abrasion
9. tooth surface that has been softened by erosion or an acid attack is more susceptible to :
abrasion and abfraction
10.Dentinal hypersensitivity has features which are similar to other condi- tions like:: 1) caries
2) fractured tooth syndrome
3) pulpitis
11.Pain upon tapping teeth suggests:: pulpitis/periodontal involvement
12.Pain on biting a stick suggests: a fractured tooth
13.How does fluoride occur?: naturally or by supplement
14.What is the accepted optimal concentration for fluoride: 0.7-1.2 ppm
15.What age group does fluorosis affect?: Children aged 8 years and younger (due to
