Outcome of Bone Recycling using Liquid Nitrogen in Biological Reconstruction Procedure in Aggressive Odontogenic Keratocystic Lesion of Mandible: A Case Report

Preethi ^[43] | Emmanuel Azariah | Deepak .C

Abstract: Odontogenickeratocysts (OKC) are benign intraosseous lesions of odontogenic origin characterised by an aggressive behaviour with a recurrence rate of 2.5 to 62.5 %. It is the third most commonly occurring odontogenic cyst comprising of approximately 20% of all odontogenic cysts. Clinically, OKC may occur in the maxilla or mandible, but it has a distinct tendency to involve the posterior body and ascending ramus of the mandible1. It has a slight gender predilection of males to females at a ratio of 1.1?2: 17. Radiographically, majority (approximately 70?80%) of OKC present as a unilocular radiolucency with a well corticated borders. But may also present as a multilocular radiolucency as well. They may be associated with an impacted or unerupted tooth which may mimic the radiographic appearance of a dentigerous cyst.
