Q

In od fibroma What is the difference between WHO type and simple type?

A

-who has
..more epi nests and cords
..dense collagen stroma to myxoid one
..stroma has calcified cementoid or dentoid

But the plump fibroblast in whorled pattern are the same

Q

Od myxoma xray

A
  • multilocilar
  • thin or thick trabeculae
  • soap bubble
  • unerupted tooth
18
Q

Fibromyxoma ?

A

When od myxoma has varying degrees of collagen fibers

19
Q

Difference between benign cementoblastoma and periapical cemental dysplasia in origin

A

Pcd is a type of bone dysplasia
Vs a
Tumor

20
Q

Difference between benign cementoblastoma and periapical cemental dysplasia in clinical

A

-pcd in black females 14:1
-pcd solitary or multiple vs single
-pcd happens in lower ant vs lower m and pm
-pcd don’t expand bone vs cementoblastoma that might expand
-pcd is max 1cm
Both are asymptomatic

21
Q

Difference between benign cementoblastoma and periapical cemental dysplasia in xray

A

-psd has 3 phases

Early late and second

22
Q

Difference between benign cementoblastoma and periapical cemental dysplasia in histology

A
  • pcd starts as fibroblastic tissue

- pcd is acellular

23
Q

Pindporg tumor is

A

CEOT

24
Q

Cementomas in pm and m region

A

All except pcd

25
Q

Cementomas more in females than males

A

All except benign cementoblastoma

26
Q

Cementomas in middle age

A

All except benign cementoblastoma in the 2nd to 3rd decade

27
Q

Only Cementoma that doesn’t cause expansion

A

Pcd

28
Q

Cementifying fibroma diagnostic problem

A

Difficult to differentiate from pcd
Has same xray
Same histo

29
Q

Florid cemento osseus dysplasia

A 
-symmetrical
Familial
Can cause large expansion
Histology
Acellular cementum with empty spaces and vascular spaces
30
Q

Aot site

A

Anterior max at canine

Central only

31
Q

Xray of AOT

A

Well defined
Unilocular
Mixed ^ snow flake
Follicular type is surrounding unerupted tooth and extend beyond the cej 75%

Extra follicular is between 2 roots 25%

32
Q

Aot expansion pattern

A

Slowly growing expansion
Asymptomatic
Less than 3cm

33
Q

Aot special histo

A
  • convoluted bands
  • sheets of spindle epi cells
  • scanty ct with cystic …
  • duct like structure
  • dentinoid rarely enamel like
34
Q

Hamartoma

A

Normal tissue in normal location in excess

35
Q

Complex vs compound odontoma in site

A

Compound – max incisor

Complex – max incisor and mand molar region

36
Q

Clinical comparison of both ododntomas

A

-both are asymptomatic small swelling may be large with bone expansion.

  • compound is mostly with permanent
  • complex is mostly in place of missing tooth
37
Q

Ameloplastic fibroma ch.ch histo feature

A

Juxta epithelial hyalinization

Narrow cell free zone around epi may be found

38
Q

Ameloblastic fibroma vs ameloblastoma?

A

-more cellular fibrous stroma
- cells of fibrous stroma is plump
-less fibrous stroma
-juxta epithelial hyalinization
- narrow cfz
-stands(plexiform 2cell layers) and follicles
Are smaller
Stallate reticulum may be messing
Microcyst are rare

39
Q

Ameloblastic fibroma xray

A

Well defined
Multi or uni locular
Un erupted tooth relation in 50%

40
Q

Variants of ameloblastic fibroma

A 
1- amrloblastic fibro odontoma 
Mand=max
Mixed ro rl
Formation of enamel and dentin
2- am.fibro sarcoma
More aggressive with metastasis 
Mesenchymal components show features of malignancy
