Abstract Background This paper describes a quantitative analysis of the cyst lining architecture in radicular cysts of inflammatory aetiology and odontogenic keratocysts thought to be developmental or neoplastic including its 2 counterparts solitary and associated with the Basal Cell Naevus Syndrome BCNS . Methods Epithelial linings from 150 images from 9 radicular cysts 13 solitary keratocysts and 8 BCNS keratocysts were segmented into theoretical cells using a semi-automated partition based on the intensity of the haematoxylin stain which defined exclusive areas relative to each detected nucleus. Various morphometrical parameters were extracted from these cells and epithelial layer membership was computed using a systematic clustering routine. Results Statistically significant differences were observed across the 3 cyst types both at the morphological and architectural levels of the lining. Case-wise discrimination between radicular cysts and keratocyst was highly accurate with an error of just . However the odontogenic keratocyst subtypes could not be reliably separated into the original classes .
