Enhances remineralization and assists stimulate saliva
○ Xylitol should be listed as first ingredient : • Inhibits attachment and transmission of bacteria
Helps prevent erosion
Xylitol
- 0.12% ….rinse 1x/daily for 1 week each month shown to reduce levels of caries causing bacteria
- Cons: alters taste, stains teeth, increases calculus formation :High and severe caries risk patients

According to the hydrodynamic theory, dentinal hypersensitivity is related to pressure from fluid movement across dental tubules to the pulp
True
Remineralization therapy is contraindicated for those with milk allergies
CPP-ACP
The most effective prevention for occlusion pit and fissure dental caries is use of 5% NaF varnish
False
Purpose of dental sealants
• To provide a physical barrier to “seal off” pit or fissure
• To prevent oral bacteria from collecting in the pit or fissure
To fill the pit or fissure as deep as possible and with a tight junction to the surface of the enamel
