Diagnosis and surgical treatment for odontogenic cysts

Odontogenic cysts are a group of benign lesions usually occurring in the jaws.Clinical diagnosis is often made by clinical features and radiographical findings which are an unilocular or multilocular radiolucency.Surgical treat-m ent of these lesions is based on the patient's age,type and size of lesion and involvment of adjacent structures.Marsupialization is especially indicated for younger dentigerous cysts if the tooth in the cyst is expected to erupte postopratively.Enucleation is usually used for smaller odontogenic cysts.Endodontic therapy shall be completed preoperatively if affending tooth or teeth of periapical cyst will be preserved.Recurrence rate may be reduced after enucleation when the Carnoy'solution is applied to treating the cyst lining or residual tissue of odontogenic keratocysts.Marsupialization followed by secondary enucleation is a choice of treatment for large odontogenic cysts,which will significantly decrease damage on associated adjacent structures.Radical resection with continuity or discontinuity defect is only indicated for extensive and multiple recurrence keratocysts after conservative surgery.
