Radicular cyst involving the deciduous dentition is rare. Most of the cases reported it with primary molar teeth with apical infection. But very rare literature is available regarding radicular cysts associated with primary incisors.
Case report: A case of 9-year-old boy, who had bilaterally impacted supernumerary teeth, had developed a radicular cyst associated with a previously traumatized and intruded right upper primary lateral incisor is reported. Supernumerary teeth and intruded primary lateral incisor were removed along with enucleation of a radicular cyst.
Conclusion: The importance of correct diagnosis and management of radicular cyst in pediatric patients is important as most of the radicular cysts of primary teeth go undiagnosed, which can affect the developing succedaneous tooth bud.
