Radicular cyst is one of the most common odontogenic cysts of the jaws, but those arising from primary teeth are very rare and comprising only 0.5 to 3.3% of the total number of radicular cysts in both primary and permanent dentitions. The aim of this case report is to present the clinical, radiographic and histological characteristics of radicular cyst associated with first primary molar. Extraction and enucleation of the cyst was carried out under local anesthesia after elevation of the mucoperiosteal flap, which led to uneventful healing. Early diagnosis of the lesion would have led to a less aggressive treatment plan.
