Six factors that play a role in caries development - Salivary gland hypofunction
5 important questions on Six factors that play a role in caries development - Salivary gland hypofunction
Name a few things saliva does or exists of to be the number 1 protector of your teeth.
- Sodium bicarbonate has a pH of 7.0
- Saliva clears food from the oral cavity
- Eating crunchy foods --> increases the saliva production
- Vitamin A+ plays huge role in production of saliva
What are the physical, chemical and antibacterial factors of saliva?
- viscous saliva = not as effective at rinsing teeth as more fluid
- as saliva flow is stimulated by chewing, amount saliva increases
- person with lot of saliva -> food clear faster --> pH returns basic faster
Chemical factors
- sodium bicarbonate, phosphates, proteins, urea in saliva --> buffer acid
- the more saliva --> more buffering chemicals available to protect teeth
- calcium + phosphorus in diet --> can saturate saliva + assist mineralization
Antibacterial factors
- mucins in saliva trap bacteria + are swallowed with saliva
- proteins in saliva may kill bacteria
- Name at least 4 sugar alcohols
- Which of them is the most desirable of all sugar substitutes + name the 3 functions it has.
Xylitol is the most desirable of all sugar substitutes:
- not metabolized by bacterial plaque
- reduces salivary streptococcus mutans in the oral cavity
- has capability to remineralize incipient decay
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
On which 7 factors is cariogenicity of the diet depending on?
- Oral clearance time
- Other food ingredients
- Frequency in which carbs are eaten
- Presence of acid-producing bacteria in plaque
- Resistance of teeth to decay
- Amount and buffering capabilities of saliva
Name 6 things that can help prevent dental caries
- Assure good amount of saliva by chewing crunchy foods (include 1 crunchy food with each meal -> clean oral cavity)
- Include cariostatic foods in our diet (as snacks)
- Pay attention to the sequence in which foods are eaten
- Consuming sugary liquids, drink after meal rather than snack
- Use of toothpaste + fluoride on daily basis to remineralize areas that have been demineralized
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
