Surgical endodontic theraphy of a radicular cyst mimicking lateral periodontal cyst and external root resorption

37615

Radicular cysts are inflammatory jaw cysts at the apices of teeth with infected and necrotic pulps. Radicular cyst treatment is mainly based on root canal treatment and if necessary surgical excision of the cyst lining with apicoectomy with retrograde filling. The lateral periodontal cyst (LPC) is an uncommon developmental odontogenic cyst. The LPC appears as a well circumscribed round or ovoid radiolucent area, usually with a sclerotic margin on the lateral aspect of a root. The vitality of adjacent teeth plays an important role in the differential diagnosis. Although radiographic examination is an important resource in clinical diagnosis; misdiagnosis may lead to extraction of teeth, unnecessary periodontal treatment and recurrence of the lesion because of inadequate radiologic examination. In this present case, surgical endodontic theraphy of a radicular cyst mimicking lateral periodontal cyst with external root resorption related to previous unsuccessful root canal treatment and large diameters of the lesion by a Erbium, Cronium: Yittrium: Scandium, Gallium and Garnet Er,Cr:YSGG laser and mineral trioxiside aggregate (MTA) is presented.
