Flashcards in Exam #2: Dental Diseases, Emergencies, and Treatments Deck (22):
1

What are dental caries?

Tooth decay

2

What is the primary etiology of dental caries?

Steptococci mutans

3

What bacteria are associated with root decay?

Actinomyces genus

4

What is the dental caries triad?

1) Tooth
2) Bacteria
3) Carbohydrate

*The combination of these three is a "recipe" for decay.*

5

What food has the highest relative cariogenicity?

*Soda/ pop* - Mountain Dew
2) Fruit drinks
3) Orange juice
4) Apple juice
5) Grape juice

6

What are the characteristics of highly cariogenic foods?

- High fermentable carbohydrate content
- Sticky
- Break into small particles in the mouth
- Causes pH to fall below 5.5
- Highly processed

7

What are the characteristics of foods with low cariogenic potential?

- High protein
- Moderate fat
- Minimal carbohydrates
- High Ca++ and phosphorus
- pH greater than 6
- Stimulate saliva secretion

8

What are anticariogenic foods?

- Foods that return pH to normal
- Foods that prevent plaque attachment
- Foods that stimulate secretion of saliva

9

What are examples of anticariogenic foods?

Cheese
Tea

10

What are coronal caries?

Dental caries involving the crown/ visible part of the teeth

11

What are the symptoms of coronal caries?

- Sensitivity to hot/cold
- Sensitivity to sweets
- Pain on biting/ mastication

12

What are root caries?

Dental caries involving the root of the tooth leading to recession of the gum-line

*****Seen in elderly population*****

13

What are the symptoms of root caries?

- Sensitivity to hot/cold
- Sensitivity to sweets
- Pain on mastication

14

What are the two major factors that contribute to dental caries secondary to soda?

- Poor oral hygiene
- Xerostomia (dry mouth)

15

What are the major causes of xerostomia?

- Medication
- Radiation
- Age
- Methamphetamine

16

What medications induce xerostomia?

- Anti-hypertensives
- Anti-arrhythmic
- Anti-hyperlipidemic
- Anti-histamines
- Anti-depressants
- Anti-parkinson's

17

What constitutes a dental emergency?

- Acute pain
- Abscess
- Cellulitis
- Injury

18

What is the definition of acute pain?

- Less than 12-24 hours
- Short or no resolution with analgesia
- With or without swelling
- Frequent drinks of cool water to quell a "hot" tooth

19

What are the different types of dental abscess?

- Intra-oral
- Extra-oral
- Pulpitis-Nerve Necrosis
- Periodontal

*****Note that these are more common in kids that are formula fed AND laid down with the bottle****

20

What are the symptoms of abscesses?

- Localized soft tissue swelling
- Erythema
- Tenderness with palpation

21

What are the symptoms of cellulitis?

- Extra-oral swelling
- Trismus (lock-jaw)
- Localized pain

22

What is Ludwig's Angina?

- A skin infection that occurs on the floor of the mouth
- Inflammation and swelling can impede the airway

*****This is a truly life-threatening dental emergency*****
