Six factors that play a role in caries development
5 important questions on Six factors that play a role in caries development
Why are starchy foods very cariogenic? And what is the danger behind combining a sliced bread with jelly?
Give examples if needed.
--> They have very retentive factors (bread, rice, snacks)
when there is already plaque -->more retentive + build up
When combined with a simple sugar --> the combination is worse than either by itself (jelly bread)
Give 3 examples in which the sequence of eating food can be beneficial for the teeth.
- Eating crunchy foods with a meal --> lets you make more saliva to --> clear the oral cavity quickly
- Drink sugary beverages with your meal, rather than separately --> drinking between provides separate acid attack
- What does the plaque biofilm consist of?
- Explain how the bacteria produces acid
- Which requirements must the bacteria in the biofilm have to play a role in the development of dental caries?
- bacteria
- polysachharides (carbs)
- proteins
- lipids
As the biofilm matures --> the bacteria creates by-product acids from --> sucrose + glucose --> the composition of the biofilm changes and is more harmful to the tooth
Those that play a role in dental caries must be:
- acidogenic = ability to produce acid
- aciduric = ability to tolerate and thrive in a acid environment
Lactic acid = most abundant
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What kind of role does tooth structure and tooth alignments play dental caries development?
- shallow grooves are less susceptible to dental caries
Tooth alignments
- straight teeth are less susceptible to dental caries
Name 4 ways in which fluoride can protect our teeth from dental caries.
- adds to reservoir of mineral available in oral cavity (absorbed by mucosal tissues)
2. Professional application of fluoride --> will arrest developing caries
3. Brushing with fluoride toothpaste --> Salivary fluoride levels are elevated up to 3 hours after brushing with fluoride toothpaste
4. Fluoride accumulates in plaque fluid and is held against enamel
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
