They may be associated with any unerupted
tooth, but most commonly with the mandibular third molars.
Bite-wing or orthopantomograph images reveal a well-defined, unilocular radiolucency with a smooth border, showing minimal bone expansion and even cortication; it is often associated with an unerupted
tooth (figure 1).
They have also occasionally been associated with an unerupted
mandibular third molar.
A dentigerous cyst is related to the crown of an unerupted
, impacted third molars occur in 20-30% of the population (1) and are most commonly noticed as a incidental finding on OPG rather than a patient presenting with symptoms.
Dental remains--mostly undamaged, unerupted

Radiographs occasionally reveal unusual intra-coronal radiolucencies in the dentine of unerupted
NEW YORK, June 20, 2012 /PRNewswire-USNewswire/ -- Beginning August 4, 2012, New Hampshire will require notification that 6-month-olds should not be routinely fed infant formula mixed with fluoridated water to avoid discoloring babies' unerupted
teeth (fluorosis), reports the Fluoride Action Network (FAN).
21 by 17 mm and a fragment of unerupted
, developing crown-cap segment represent pieces of cheek tooth from a mammoth, Mammuthus, of indeterminate species.
The skulls were radiographed to identify unerupted
teeth (Figure), which were then aseptically extracted.
The dentigerous cyst encloses the crown of an unerupted
tooth by expansion of its follicle and is attached to the neck.
Other areas may require X-rays for more specific reasons outwith these times, such as checking roots, crowns, unerupted
teeth or to plan treatments.
