There are several kinds of odontogenic cysts with a range of clinical significance.
Types:
(1) root-related
(2) crown-related
(3) other
Root-Related |
Features |
peri-apical (radicular) |
most common, associated with pulpal injury associated with trauma or dental caries |
residual |
peri-apical cyst remaining after tooth extracted |
lateral periodontal |
along the roots of mandibular cuspids or bicuspids |
botryoid odontogenic |
polycystic variant of lateral peri-odontal cyst |
Crown-Related |
Features |
paradental |
partially erupted mandibular third molar |
dentigerous |
surrounds the crown of a nonerupted permanent tooth, most often a third molar or maxillary cuspid |
eruption |
bluish or bluish-red dome-shaped lesion affecting an erupting deciduous tooth |
Other |
Features |
gingival |
congenital, with cystic degeneration of the dental lamina |
odontogenic keratocyst |
nevoid basal cell cancer syndrome (multiple basal cell carcinomas, skeletal anomalies, dyskeratotic pitting of hands and feet, ectopic soft tissue calcifications, ovarian fibromas, lymphatic mesenteric cysts, hypertelorism, medulloblastoma, etc) |
calcifying odontogenic |
Gorlin cyst; mandibular cyst with ghost cells, seen as a cystic radiolucency with areas of opacification (calcifications) |
glandular odontogenic (sialo-odontogenic) |
usually a multi-locular radiolucencies in the anterior mandible |
