Lateral periodontal cysts are very rare in children.
ODONTOGENIC KERATOCYSTS
The odontogenic keratocyst is the most aggressive of the jaw cysts. It has a high rate
of recurrence due to the fact that remnants left after subtotal removal will regenerate.
These cysts may be found in children and may be associated with the Gorlin-Goltz
syndrome. Keratocysts associated with this syndrome appear in the first decade of
life, whereas the syndromic basal-cell carcinomas are rare before puberty. Other signs
and symptoms include: multiple basal-cell carcinomas, bifid ribs, calcification of the
falx cerebri, hypertelorism, and frontal and temporal bossing.
NON-ODONTOGENIC
These include the nasopalatine duct cyst which may occur clinically as a swelling in
the anterior mid-line of the hard palate. The radiographic appearance is a radiolucency
of greater than 6 mm in diameter in the position of the nasopalatine duct. The anterior
teeth have vital pulps. Surgical excision is curative. The so-called globulomaxillary
cyst, which occurs between the lateral incisor and canine teeth, is now thought to be
odontogenic in origin. It is either a radicular cyst or an odontogenic keratocyst.
The haemorrhagic bone cyst is a condition that may be found in children and
adolescents. It occurs most commonly in the mandible in the premolar/molar region.
It is often a chance radiographic finding and normally asymptomatic.
Radiographically it appears as a scalloped radiolucency between the roots of the teeth.
It regresses spontaneously or after surgical investigation.
