Ch.13 Week 1 Flashcards
What two types of bacteria primarily caused dental caries
Mutans streptococci
Lactobacilli
What is the soft sticky bacterial mass that adheres to the teeth
Plaque
What is the mineral in the enamel that makes the crystal easier to dissolve ?
Carbonate apart
Prisms
Hydroxyapatite microscopic crystals that are arranged like layers or rods
For Caries to develop the following three factors must be present at the same time
1 a susceptible tooth
2 A diet rich in fermentable carbohydrates
- specific bacteria
Carious lesions can occur in for general area of the tooth
1 pit and fissure caries occurs primarily on occlusal surfaces lingual grooves and lingual pits
- Smooth surface caries occurs on enamel surfaces
- Root surface caries
- Secondary curies
Disease indicators, risk factors, and protective factors of the caries imbalance
How to control tooth decay
Diet fluoride remove plaque saliva antibacterial mouth rinses and dental sealants
Demineralization
What is the term for rapid and extensive formation of Carrie’s
Rampant caries
What is the term for caries that occurs under or adjacent to existing dental restorations
Secondary caries
Why are exposed root surfaces more susceptible to caries than enamel
It has less mineral content and is more soluble therefore more susceptible to root Carries
Early childhood caries
It’s an infectious disease that can happen in any family and is very painful
What are the risk factors in early childhood caries
Low income families, particular ethnic groups, midget access to care, lack of water fluoridation
How children get early childhood Carrie
It’s a transmissible disease where if bacteria is present in the parents and caregivers mouth it can get passed on to child
