The spectrum of inflammatory and developmental odontogenic cysts.
Int J Pathol Jan ;8(1):26-9.

Objective: To study the spectrum of inflammatory and developmental odontogenic cysts. Introduction: Epithelial lined cysts of the oral cavity are among the most commonly encountered oral diseases from both the clinicians and pathologists perspective. To reach a specific diagnosis a multi team approach is necessary which includes radiologists, surgeons and pathologists. Two major categories of cysts exist; odontogenic and non-odontogenic. The most commonly encountered odontogenic cysts are radicular or periapical cyst; which may occur in any age group but common in 3rd and 4th decade. The second common type is dentigerous cyst that accounts for 17% of all the odontogenic cysts. Keratocysts account for 10% of all odontogenic cyst and can have more chances of recurrence. Materials and Methods: 60 cases sent to the Pathology Department during Sept. 2006 to Dec 2009 were included in the study, after observing inclusion and exclusion criteria. After gross examination the sections were routinely processed and slides stained with H& E. All the slides were thoroughly examined by two consultant histopathologists and postgraduate pathology resident. Results and conclusions: 50% were radicular cysts, 36% were dentigerous cysts, keratocysts and eruption cysts accounted for 8% and 5% respectively. In one case of dentigerous cyst ameloblastoma was diagnosed and one case was diagnosed at maxillary antrum, an unusual site for dentigerous cysts.
