Introduction

 The solitary keratocystic odontogenic tumor (KCOT) is a neoplasm, which recurs in 28% of cases. The purpose of this study is to determine whether clinicoradiographic features can predict recurrence.

 Material and Methods

 From 2000 to 2009, 106 solitary KCOTs were retrieved from the Oral Biology Service of British Columbia. Among 58 KCOTs including all recurrent KCOTs (rKCOT) and nonrecurrent KCOTs (nrKCOT) (followed up for at least 5 years), only 29 had radiographs (rKCOT, 18 nrKCOT, 11).

 Results

  Patients with recurrences were significantly older than those without. Interestingly, those cases, which were considered KCOTs before surgery, were significantly more likely not to recur within 5 years of follow-up. Most radiological features did not differ between nrKCOT and rKCOT on the basis of panoramic radiography only.
