Q

SOS

Odontogenic Myxoma (OM) diagnosis:

A
  • Most commonly, it occurs in young adults
  • The mandible is involved more frequently
  • Is usually painless, displacement of teeth
  • it reaches considerable size before being detected, and perforation of the cortices of the involved bone may be seen
28
Q

SOS

MRONJs definition:

A

=medication related osteonecrosis of the jaw
=area of exposed bone in the maxillofacial region that did not heal within 8w after identification by a health care provider, in a patient who was receiving or had been exposed to a bisphosphonate and didn’t have radiation tx to the craniofacial region

29
Q

MRONJs stage 2:

A

exposed necrotic bone - bone that doesn’t bleed

30
Q

MRONJs treatment:

A
  • eliminate pain
  • control infection of the soft and hard tissue
  • stop/minimize the progression of disease
  • prescribe antibiotics and remove any mobile bony sequestra to facilitate soft tissue healing
  • extraction of symptomatic teeth
  • histologic analysis for all resected bone specimens
31
Q

SOS

Which of the lesions is categorized potentially malignant disorder?

(a) ameloblastoma
(b) frictional keratosis

Discoid lupus erythematosus
Dyskeratosis congenita
Fanconi anemia
32
Q

Leukoplakia types:

A

• Homogeneous leukoplakia, a lesion of uniform flat appearance that may exhibit superficial irregularities, but with consistent texture throughout, generally well-demarcated
• Non-homogeneous leukoplakia, a predominantly white or white and red lesion (erythroleukoplakia)
with an irregular texture that may include ulceration and may be characterised by a speckled, nodular or verrucous topography. These lesions have a higher risk for malignant transformation

33
