Abstract

Dentigerous cysts are odontogenic cysts associated mostly with the crowns of unerupted permanent teeth. This article reports the case of a 10-year-old child who presented with a swelling associated with a carious deciduous tooth. Radiographically, the cystic lesion involved its permanent successor. The presumed radicular cyst was marsupialised, histopathologic evaluation uncurtained the dialemma and diagnosis of an infected dentigerous cyst was established. In the follow- up appointments, impacted 35 was seen positioning itself spontaneously towards eruption.
