VALIDITY OF MODIFIED CARNOY’S SOLUTION AS A CHEMICAL CURETTAGE FOR TREATING KERATOCYSTIC ODONTOGENIC TUMOR: AN IN-VIVO STUDY

Introduction: Maxillofacial surgeons usually face difficulty in treating odontogenickeratocysts since it has a high risk of recurrence and are small and delicate, whichprevents one-piece enucleation. Aim: To assess the effectiveness of modified Carnoy’ssolution as a chemical curettage method for treating Odontogenic Keratocysts andlowering their propensity to recur. Material and Methods: The current study includedtwelve patients diagnosed with having odontogenic keratocysts either in the maxillaor mandible. The lesion was enucleated and any teeth adhering to the lesion wereremoved. Modified Carnoy’s solution was applied for 3-5 min using ribbon gauze orcotton applicators in the bony cavity and the fenestrated area where excision of theoverlying soft tissue was not possible. After thorough irrigation with saline, then thewound was closed with a resorbable suture. During the follow-up visits (six and twelvemonths after surgery), the presence and/or rate of recurrence were examined clinicallyand radiographically by panoramic radiography to evaluate presence of osteolyticareas in the surgical site. Results: The recurrence rate of odontogenic keratocysts inthe present study after six months follow up was 8.3% and after twelve months followup was 33.3%. Eight patients showed no recurrence after twelve months follow up,while one patient showed recurrence after six months and the remaining three patientsshowed recurrence after twelve months follow up. Conclusion: The recurrence rate ofOKC was reduced in the current trial using a modified version of Carnoy’s solution,nevertheless, it is still considered high compared to conventional treatment techniques.
