**anorexia, acid reflux, bulemia

7

when looking intraorally, what gives the indication of bulimia?

Lingual surfaces are eroded

8

What is extrinsic erosion?

erosion that occurs when dietary acids contribute to the mouth's being in a very acidic state

9

. sugar, diet sodas, fruit drinks, carbonated drinks, energy drinks, etc

10

at what pH level does enamel begin to erode?

5.5

**soda has average ph of 2.5

11

when enamel wear down, 4 what things can occur?

1- teeth become discolored because you can see dentin
2- edges of front teeth look transparent
3- tooth sensitivity
4- restorations will chip and fall out, especially in primary teeth

12

what is external root resorption?

the breakdown or destruction and subsequent loss of the root structure of a tooth.

13

what causes external root resorption?

living body cells attacking part of the tooth

*happens in both perm. and primary teeth

14

What results from pressure on the root surface. It can be from trauma, ectopic teeth erupting in the path of the root, chronic inflammation. Most common cause is Orthodontics!

Root resorption of secondary teeth

15

What is Ectopic root resorption

Whenever the crown of one tooth, comes close or in contact with the root of another tooth

16

what is internal root resorption?

root and dentin resorb within root canals

17

what cause internal root resorption?

trauma, and sometimes unknown etiology

18

How can a dentist cause internal root resorption?

the pulp can react to materials and methods used during pulpotomy

19

is a primary tooth more likely to move within the bone or fracture?

move within bone because the surrounding bone isn't as thick as it is with permanent teeth

20

what are the 6 soft tissue problems listed in the lecture?

1-Acute & Chronic Alveolar Abscess
2-Cellulitis
3- Gingivitis
4-Periodontal Disease
5-Soft Tissue Trauma
6-Benign & Malignant Lesions

21

what is a acute alveolar abscess?

It is a chemical bacterial and mechanical irritation but usually due to bacterial invasion from death of pulp tissue

22

what happens when the swelling becomes extensive?

it results into cellulitis and the patients facial appearance changes

23

what is cellulitis?

diffuse infection of the soft tissues

24

does cellulitis occur more in adults or kids

younger children

25

what causes cellulitis?

primary or permanent pulpal necrosis

26

clinically how is cellulitis characterized?

by considerable swelling of face or neck due to collateral edema and a spreading fascial infection

27

is cellulitis painful?

yes. May have difficulty sleeping or eating

28

what results from long standing, low grade infection of the periradicular bone?

chronic alveolar abscess

29

is chronic alveolar abscess painful?

No. generally no obvious signs or sypmptoms

30

Gingivitis

bacteria in plaque...easy bleeds...no bone loss
