  1. Affect any unerupted tooth but mainly &-3.

3

4 Deciduous teeth rarely affected & may associate supernumerary tooth. Asymptomatic and discovered when the eruption of tooth is delayed.

6 Large cysts may cause cortical expansion of bone & facial asymmetry. Painful if infected by hematogenous route or PDL disease or

Q

X ray of dentigirous ?

A

Unilocular radiolucent area on crown of unerupted tooth

with well-defined sclerotic (opaque) border.

o Large cyst may be multilocular radiolucencies.

o If infected →ill-defined border.

CLINICO-RADIOGRAPHIC CLASSIFICATION: (according to relation with tooth)

o Central most common, cyst surround crown attach at CE), o Lateral cyst partially surround crown.

o Circumferential cyst surround crown and enclose a large portion of root

Less than 2mm
Spontaneous healing
Multiple
More in max than mand

20
Q

HistoPayhology of gingival cyst of newborn

A

St sq k epi
Thun epi
Nodular thickening

21
Q

Epstein pearls

A

Inclusion non od keratinised cyst at midline of the palate

22
Q

Gingival cyst of adult ?

A
  • from epi rest of d lamina in ging.
  • non k
  • non specific histo
  • age –5th to 6th
  • site – mand pm and c gingiva
  • slowly growing painless
  • cupping of cortex
  • vital adjacent teeth
23
Q

Lateral periodontal cyst?

A

Non keratinized developmental odontogenic cyst lateral to root of the tooth within bone.

o Arise from epithelial rest of dental lamina

in bone

  1. Age 20-60 years.
  2. Sex males > females.
  3. Site →more in mandible

(premolar & canine area).

  1. Painless slowly growing.
  2. Adjacent teeth are vital.

o Well defined round or tear

drop RL area surrounded by RO margin between 2

adjacent roots.

o Thin non keratinized stratified squamous epithelium.

o Nodular thickening may be

present in the epithelial lining.

o Numerous daughter microcysts may be found in CT wall.

24
Q

Origin of OKC

A

Arise from cell rests of dental lamina

Mechanism of its growth is due to: unknown factors

o Vakoown factor inherited in setthelial es

inherent in epi tous.

EnZymatic Activity of fibrous a wall

so it

may be considered as benign cystic neoplasm (named keratocystic odontogenic tumor).

25
Q

OKC clinical

A

Age 10-40 years.

  1. Sex 60-80% of cases in males.
  2. Sitemandible> maxilla (mainly in posterior part of mandible and ascending ramus).
  3. If small asymptomatic.
  4. If large painless or painful.
  5. Grow in antero-posterior direction (Le. In medullary bone not causing obvious bone expansion). 7. Occasionally parasthesia of the lower lip may be present.
26
Q

OKC radio picture

A

R/E:

o Small cysts → usually unilocular, well defined radiolucent area with well-defined radioopaque

margin.

a Large cysts → multilocular radiolucent area.

May be associated with unerupted tooth. o Resorption of adjacent roots may be seen.

27
Q

Ttt and prog of OKC

A
  • friable ct wall don’t allow removal as one piece
  • cautterization with carnoy solution allows separation from bone and decreases recurrence
  • bur peripheral osteotomy with reconstruction and graft
  • 30%recurrence
  • rare carcinoma transformation
28
Q

Gardner goltz syndrome

A

Autosomal dominant condition which reveals:

Multiple BCCs.

Multiole odontogenic keratocysts

Bifid ribs.

Broad nasal bridge.

© Mandibular prognathism.

o Frontal bossing.

o Vertebral kyphosis.

o Intracranial calcifications.

o Palmer and plantar pits.

o Ovarian fibromas in females.

o Cleft lip & palate.
