for regular dental check up.
On Radiographic examination
You find…
                         CASE 1
• On the anterior mandibular periapical
  radiograph there is a well defined
  radiolucent area with sclerotic borders
  present at the root apices of mandibular
  central and lateral incisors. It is well
  defined and localized. Is not causing the
  displacement or resorption of adjacent
  teeth. There is no gross carious lesion or
  sign of trauma in the area. The appearance
  is consistent with periapical cemento-
  osseous dysplasia.
                        CASE 1

Can have three stages
radiolucent,
mixed or completely
radiopaque.
Common in middle
aged women specially
Afro-American.
Associated teeth are
vital.



                         Periapical Cemento-osseous dysplasia.
Periapical Cemento-
osseous dysplasia. Mixed
radiolucent and
radiopaque stage with
simple bone cyst arising
within the lesions of
cemento-osseous
dysplasia.
                               CASE 2
• Patient presented with pain in
  the lower left posterior area.
  On the left posterior periapical
  radiograph there is a
  radiolucent area associated
  with the root of mandibular left
  second premolar. The area is
  well defined, corticated. No
  displacement of adjacent teeth
  or resorption of the root is
  seen. The associated tooth
  has a big carious lesion and
  horizontal bone loss. The C:R
  ration is 1:1. Evidence of
  calculus in the general area is
  seen.
                       CASE 2
• The appearance
  is consistent with
  radicular cyst.
                         CASE 2
• The radiolucent area
  associated with
  periapical region of
  mandibular left
  second molar is
  irregular and the
  appearance is
  consistent with
  rarifying osteitis.
  This is the probable
  cause for pain.

                      CASE 5
• Patient presented for
  routine dental exam. On
  mandibular right premolar
  periapical radiograph
  there is a well defined,
  corticated and unilocular
  radiolucent area in
  between the roots of
  canine and 1st premolar.
  The periodontal ligament
  space is intact on canine

  displacement or
  resorption of the adjacent
  teeth
Lateral periodontal cyst
                       Case 6

  corticated and unilocular
  radiolucent area in
  between the roots of
  lateral incisor and canine.
  The periodontal ligament
  space is intact on these
  teeth. Slight displacement
  of the adjacent teeth is
  noted. The lesion is not
  causing expansion or
  resorption of the adjacent
  teeth
                              CASE 7




•   48 year old patient presented with slow growing (past 6 months) facial
    swelling of right side. Pt. does not complain of pain or discomfort. On
    radiographic examination there is a well defined and corticated radiolucent
    area associated with the crown of mandibular right 3rd molar. The radiolucent
    area extends from the apices of 1st molar to neck of coronoid and condylar
    process. It has caused thinning of the lower border of the mandible. 3rd molar
    has been displaced apically.
Dentigerous cyst: The epicenter of dentigerous cyst is coronal to the crown of
the involved tooth. The cyst is attached at CEJ but when it enlarges the tooth appears
to be within the cyst. Dentigerous cyst is completely radiolucent and is well
defined and corticated. It can resorb and displace adjacent teeth. Usually displace the
associated tooth in an apical direction. 3rd molars may be displaced to the condylar or
coronoid process or to the inferior border of the mandible.
