Mean age of the patients with radicular cyst (n= 48) was 24.81 +-14.08 years while mean age of patients with OKC (n=22) was 27 +-13.91 years.
There are three major categories of odontogenic cyst: dentigerous cysts, keratocystic odontogenic tumors, and radicular cysts. (3,4)
As radicular cyst is the commonest of the odontogenic cyst this is because it is almost always associated with dental carries and necrotic pulp and a high frequency of dental carries in our population22 becomes the commonest reason for this cyst.
Among the odontogenic cysts of the jaws, the radicular cyst (also called periapical cyst or apical periodontal cyst) is the most common.
(7,8) Male dominance, especially for radicular cysts, has been associated with increased maxillofacial trauma and poor oral hygiene.
A provisional diagnosis of radicular cyst, residual cyst, glandular odontogenic cyst, aneurysmal bone cyst was made.

These typical inflammatory peri-apical lesions are common and encompass primarily the peri-apical periodontium, with no preponderance of race, sex or age.3 It is the most frequent peri-radicular pathology and involves ~ 40 percent of all peri-apical radiolucent pathologies.3 In about 90 percent of the cases, a well-defined radiolucency at the apical area of an untreated asymptomatic tooth with a non-vital or diseased pulp is either a dental granuloma or a radicular cyst.3
Although odontogenic cysts are very common lesions in routine practice, with radicular cysts accounting for more than 50% of cases, it should be remembered that many other diseases can affect the jaws, some more frequently than others [1].
DC, dentigerous cyst; KOC, keratinizing odontogenic cyst; GC, gingival cyst; BOC, botryoid odontogenic cyst; LPC, lateral periodontal cyst; RadC, radicular cyst; and ResC, residual cyst.
The most prevalent odontogenic cyst was radicular cyst n=45(45%) followed by dentigerous cysts n=31(31%), odontogenic keratocysts n=14(14%), lateral periodontal cysts n=6(6%) and gingival cysts n=4(4%).
Dentigerous cyst is the most common developmental cyst, estimated to be about 20% of all jaw cysts while radicular cyst is the most common inflammatory jaw cyst.
