Clinicopathological analysis of odontogenic cysts in a selected Pakistani population

ABSTRACT

The cysts of the jaw are broadly classified as odontogenic and non-odontogenic. The odontogenic cysts are pathological fluid filled cavities lined by odontogenic epithelium and further sub-classified as inflammatory and developmental. The objective was to determine the types, frequency, distribution, and demographic characteristics of odontogenic cysts in our setup. This 8 years retrospective study [from January 2003 to December 2010] was conducted at Histopathology department of Armed Forces Institute of Pathology, Rawalpindi [Pakistan]. The histopathology record of odontogenic cysts were reviewed for age, gender, site, associated tooth and histopathological diagnosis. The data was analysed by using SPSS soft ware package version 17. The data revealed that periapical, dentigerous and odontogenic keratocysts were the most commonly reported odontogenic cysts which reported in the age range of 4 to 72 years [mean 29.09 +/- 13.53 years]. Amongst them 67.7% were males and 32.3% females with peak incidence in the 2[nd] and 3[rd] decades. The association of age and teeth with different type of cysts was statistically significant while gender association was insignificant although having predilection for males. None of the case of odontogenic keratocyst was found in deciduous teeth. The statistically significant association of different types of Odontogenic cysts with the age, site, teeth and male prevalence reveals that demographic knowledge can be helpful in early diagnosis and their prompt treatment
