Management of true lateral infected radicular cyst as well as associated mucosal fenestration that occurred postoperatively through an interdisciplinary approach: A rare case report

A radicular cyst (RC) is one of the types of inflammatory cyst of odontogenic origin. It is usually associated with nonvital teeth and is mostly observed in males. It is routinely treated by nonsurgical endodontic therapy; however, if the cystic lesion does not respond to endodontic therapy, then surgical intervention with or without regeneration is the treatment of choice, depending upon the size, location of lesion, the bone integrity of the cystic lesion wall, proximity to vital structures and residual bone defect elicit after enucleation, etc., We hereby present successful interdisciplinary management of rare true lateral RC in the interproximal site with respect to teeth number 21 and 22 as well as associated mucosal fenestration that was occurred postoperatively other than its apparent etiology and diagnosis.
