hot beverages

Front 21

The most common sites for INTRAORAL THERMAL BURNS are:

Back 21

- buccal mucosa
- palate

Front 22

NECROSIS is the result of:

Back 22

localized ischemia, probably from faulty injection technique or the apinephrine.

Front 23

What is the treatment for ANESTHETIC NECROSIS?

Back 23

No treatment unless ulceration fails to heal

Front 24

What are some health-related risks associated with ORAL PIERCING?

Back 24

- bleeding
- pain
- swelling
- infection
- lingual nerve damage
- calculus build up on metal
- reaction to metal
- gingival/mucosal trauma
- tooth chipping/fracture
- hypersalivation
- speech impediment
- aspiration of jewelry
- obscuring radiographs
- hyperplastic/keloid tissue formation

Front 25

Define ANTRAL PSEUDOCYST:

Back 25

dome-shaped, fairly radiopaque lesion arising from the floor of the maxillary sinus. Consists of inflammatory exudate (serum) that has accumulated under the max. sinus and caused a sessile elevation.

Front 26

What is the treatment of ANTRAL PSEUDOCYST?

Back 26

No treatment, harmless.

Front 27

What is a SINUS MUCOCELE?

Back 27

an accumulation of mucin the is completely encased by epithelium

Front 28

SINUS MUCOCELE occurs in what two situations:

Back 28

1) occurs after trauma/surgery to the sinus: SURGICAL CILIATED CYST. Most often from Caldwell-Luc operation

2) Obstruction of sinus ostrium, blocking normal drainage

Front 29

What is the treatment of SINUS MUCOCELE?

Back 29

Should be removed.

Front 30

What is a RETENTION CYST?

Back 30

Arises from partial blockage of a duct of the seromucous glands or from an invagination of resp. epithelium.

Front 31

Patients with which condition/ syndrome have a tendency for self-mutilation, which is often directed to the oral tissues with use of teeth or fingernails?

Back 31

Gilles de la Tourette

Front 32

BISPHOSPHONATES affect what?

Back 32

Inhibit osteoclasts and possible interfere with angiogenesis

Front 33

What are the four stages of BRONJ?

Back 33

Stage 0 - no apparent exposed / necrotic bone (but present with signs suggestive of future disease)
Stage 1 - Exposed / necrotic bone in asymptomatic patient with no evidence of infection
Stage 2 - Exposed / necrotic bone with localized infection
Stage 3 - Exposed / necrotic bone with pathological fracture, extra-oral fistula or extention into surrounding basal bone

Front 34

What are some health-related risks associated with oral piercing?
