Pak Oral Dental J Jan ;36(4):542-5.

The objective of the study was to determine the demography, frequency, male female ratio and jaw involvement in odontogenic cysts. This retrospective study was carried out from Jun 2004 to July 2008 at the Department of Oral and Maxillofacial Surgery, Khyber College of Dentistry, Peshawar. A total of 100 cysts formed the study group. The age ranged was ≥ 20 years and were divided into five groups. The data were analyzed through SPSS 22 at the level of significance p≤ 0.05. Student–Newman–Keuls test was used to show the significant distribution in the aged groups. Chi-square statistics were used to show the association of the cyst with the jaw. The male to female ratio was 1:1.33. The dominant age group in males was 20-29 years n=15(34.88%) while 40-49 years age group was more in females n=18(31.57%). The maxilla to mandible involvement was 1:1.33. 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%). The Student–Newman–Keuls test showed that the cyst distribution in the aged group (30-39years) was statistically significant in both males (p=0.017) and females (p=0.011). Chi-square statistics showed a significant association of radicular cysts with anterior of maxilla (x2= 10.369, p= 0.005), dentigerous cysts with molar area of the mandible (x2= 10.917, p= 0.004) while other odontogenic cysts were statistically not associated with location of the jaw.Radicular cyst were the most prevalent odontogenic cyst and odontogenic cyst distribution in the aged group was statistically significant in gender
