Is this Caries or Erosion?

A. Caries B. Erosion

Is this Caries or Erosion?

A. Caries B. Erosion

Is this Caries or Erosion?

A. Caries B. Erosion

Saliva provides a natural, primary protection from caries and erosion when:

A. It is in its normal healthy state as supersaturated with calcium & phosphate B. It is undersaturated with Calcium and Phosphate where it pulls mineral density from tooth structure C. Hard tissue sites are poorly bathed with saliva D. Its flow is reduced such that it can’t buffer (e.g due to medication or Sjogren’s)

The main components of the mineral apatite of Enamel are all but which?

A. Calcium B. Phosphate C. Organic materials D. Millions of Prisms made of tightly packed crystals that form rods

Which one is not a risk factor for Caries?

A. Plaque Biofilm B. Reduced Salivary Flow C. Frequent Snacking D. Acquired Pellicle

Which is not a risk factor for Erosion

A. Plaque Biofilm B. Acidic Food or Beverages C. GERD D. Reduced salivary flow

Which fluoride is highly effective against caries and erosion?

A. Amine Fluoride B. Stannous Fluoride C. Sodium Monofluorophosphate (SMFP) D. High concentration Sodium Fluoride (ex 5000ppm)

Which condition is associated with Irreversible Surface Mineral Loss where the pellicle and saliva buffer capacity is overwhelmed?

A. Caries B. Erosion

Which condition is associated with subsurface mineral loss influenced by weak bacterial acids and is reversible in early stages?

A. Caries B. Erosion

Which is not a prevention strategy for Caries?

A. Daily plaque biofilm control B. Neutralize bacterial acids C. Reduce tooth solubility D. Increase Snacking frequency

The reason the outer layer of enamel remains sound while the subsurface layer loses mineral density is: (remin demin Video)

A. The bacterial biofilm creates a new barrier B. As the Calcium and Phosphate flow toward the surface some re-precipitates at the surface C. The saliva stops drawing Calcium and Phosphate out of the tooth D. Fluoride only remineralizes the surface

Which is not true about how Fluoride works?

A. Fl helps reduce net mineral loss during demineralization B. Enhances the density of the re-formed mineral C. Bactericidal for S. Mutans D. Aids in the formation of fluorapatite which is more resistant to cariogenic bacterial acids

What is the primary way to prevent erosive damage?

A. Dietary Counselling B. High concentration fluoride C. Biofilm control D. Calcium Supplements

What is generally accepted to be the critical pH where net mineral density is lost from hydroxyapatite?

A. 6.1 B. 5.5 C. 2.3 D. 8.3
