TURKU, Finland: Purportedly arising from remnants of the dental lamina, odontogenic keratocysts (OKCs) make up roughly 5%–15% of all odontogenic cysts and appear as either a solitary lesion or multiple lesions. They typically grow rapidly and have high rates of recurrence. Research conducted at the University of Turku on a Finnish population has found that patients with OKCs tended to be older at the time of diagnosis and their cysts were more commonly inflamed than has been reported in the literature. The findings suggest a delay in diagnosis, as OKCs are often asymptomatic and can go undetected until symptoms like swelling or infection manifest.
