What is this hyperplastic response within the epithelium? It creates acanthosis and hyperkeratosis that produces a line of leukoplakia.
|

|
Explain the formation process of a traumatic ulcer
|
1. An ulcer is a complete loss of the epithelial surface covering
2. Exposed connective tissue allows microorganisms to invade into the tissue causing inflammation 3. Vascular changes of inflammation create an Exudate 4. exudate will cover over the surface with a Fibrin Clot 5. fibrin clot tends to be white or yellow due to moist environment 6. Most oral ulcers will be red at first because there is not enough time to create the fibrinous exudate (this is the pseudomembrane) 7. Areas of erythema (red halo) that surrounds central yellow pPeudomembrane (ulcer) or Focal Red Ulcerated Area Without Fibrin Covering |
|

|
heals within days
|
|
What conditions are related to slowly healing ulcers?

|
What is the and what are the two factors that can deprive the tissue of oxygen, causing it to undergo necrosis?
|
1. Physical Blockage of Flow - you're filling a confined space that normally would have blood flowing in it. You're displacing that blood flow by putting fluid into it and pushing back on the blood flow
2. Chemically Induced Stricture of the Vasculature - often, local anesthetics used in dentistry contain a vasoconstrictor |

|
Lead
|
|
|
What type of systemic Metallic intoxication results in metallic taste, ulcerative stomatitis, inflammation and enlargement of salivary glands, gingiva, and tongue. Gingiva may become blue-gray to black, destruction of alveolar bone and exfoliation of teeth, Acrodynia (pink disease, Swift disease) from chronic mercury exposure in infants and children. Oral symptoms include excessive salivation, ulcerative gingivitis, bruxism, premature loss of teeth.

Mercury
|
|

|
Mercury
|
|
|
What causes Argyria, which manifests as a diffuse bluish-black discoloration?
|
Silver
|
|
What is a Dome-shaped radiopaque lesion arising from the floor of the maxillary sinus that results in sessile elevation from inflamatory exudate and most of these disappear on their own in a 6-9 month period?
|
Antral pseudocysts<BR>(antral = maxillary sinus)
|
|
How does cervicofacial emphysema occur?
|
It arises from air forced into subcutaneous or fascial spaces of face and neck
|
|
|
What condition can manifest as CREPITUS (crackling) synchronous with heartbeat (Hamman's crunch)?
|
Cervicofacial Emphysema
|
|
How might air get into fascial spaces of the face and neck, creating cervicofacial emphysema?
|
If you're using an air/water syringe and blowing in the patient's tissue, if there is no attached gingiva and you are blowing in the sulcus, where is the air going to go? Down into the patien's tissue somewhere. Along with that air, you are sending oral microbes. The organisms can start spreasing through tissue (even the mediastinum) and cause problems. Most cases resolve spontaneously or you may treat with antibiotics
