Radicular Cyst in the Lower Right Primary Tooth and Its Management: A Case Report

Radicular cysts are the most common inflammatory odontogenic cysts but are relatively uncommon in the primary dentition. When present, they may cause significant destruction and adversely affect the eruption of permanent teeth. A 6‐year‐old boy presented with painful swelling in the right mandibular buccal region. Radiographic examination revealed a large, well‐defined unilocular radiolucency associated with the right primary second mandibular molar, previously treated with pulpectomy. The affected tooth was extracted, and the cystic lesion was completely enucleated. Histopathological examination confirmed the diagnosis of a radicular cyst. Early recognition and surgical management of radicular cysts in primary teeth are crucial to prevent damage to developing permanent dentition. Long‐term follow‐up in this case demonstrated satisfactory bone healing and normal eruption of the permanent teeth.
