PRVNT FINAL Flashcards
First stage of a carious lesion
Incipient caries
What groups of bacteria responsible for caries
Mutan streptococci lactobacilli
Cariogenic
Any food containing sugar or other carbs that can be metabolized by bacteria in plaque
Demineralization
Dissolution of calcium and phosphate from hydroxyapatite crystals
Remineralization
Process by which fluoride protects teeth from decay
Drinking diet soda lowers the pH of the oral cavity to ….
5.5
What substance within the saliva is an antibacterial protection
Immunoglobulin
What groups of patients can fluoride varnish be used with
All
What can be used to clean a denture
Commercial denture cleaner, dishwashing and mild soap
What are caries risk assessment tests
Measuring saliva flow and bacteria amount
Process of demineralization and remineralization
Can occur without loss of tooth structure, continual process, more demineralization than remineralization carious lesions develope
The presence of what indicates patient has high sugar intake
Lactobacilli (LB)
Purpose of placing sealants
Protect difficult to clean occlusal surfaces of teeth to keep bacteria from getting in pits and fissures
When should baby first visit dentist
By first birthday
How long does acid from diet and sugar free sodas attack the teeth
20 minutes
What component in saliva strengthens the tooth and assists with remineralization
Calcium
What can be used to slow caries process
Fluoride
Most prevalent childhood disease
Early childhood varies
What does caries process require
Susceptible tooth, diet rich in fermentable carbs and specific bacteria
First step in forming partnership with patient to prevent disease
Help understand what causes it and how to prevent
What reduces streptococci mutans
Xylitol
Root caries
Carious lesion found in elderly
What is rampant caries caused by
Xerostomia and eating frequent or excessive amounts of sugar
What’s a factor in carcinogenicity of carbs
How long food stays in the mouth
Best way to visualize plaque on teeth
Disclosing agents
Where is early childhood caries most prevalent
Lower socioeconomic families with limited access to care, specific ethnic groups, areas lacking fluoridated water
What are oral irrigation devices used for
Reduce bacterial levels in subgingival and interproximal areas
Nutrients provide a body with
Growth energy and maintenance
Sources of carbs
Cereal grains, sweets, vegetables
Can dental caries develop without sugars present
No
What describes the sonic care automatic toothbrush
Brush head vibrates with sound
What mineral in enamel makes crystals easier to dissolve
Carbonated apatite
