Radicular Cysts in Primary Dentition with Different Clinical and Radiographic Characteristics

Abstract

Radicular cysts are considered rare in primary dentition. The aim of this article was to present two cases of radicular cysts associated to primary molars with different characteristics. Two children sought care at a dental clinic with complaints of a painless swelling and the absence of a premolar, respectively. The first case was a seven-year-old boy who complained of an increased volume in the region of the mandibular right primary second molar. The second case was a 12-year-old girl, who complained of the absence of the mandibular right second premolar and gingival inflammation. In both cases, surgery was performed to remove the lesion and the elements involved. Histological examinations confirmed the radicular cysts. After six months, complete regression of the lesions was reported, and the patients were referred for orthodontic treatment. Radicular cysts can cause damage to the elements involved, adjacent teeth and the occlusion of the patient.
