Deceptive Radiolucency: Unmasking a Radicular Cyst in mixed dentition of an 8 year old girl.

AbstractRadicular cysts are the most common inflammatory odontogenic cysts, predominantly associated with permanent dentition. However, their occurrence in primary teeth is rare, representing only 0.5-3.3% of all radicular cysts. They often arise as a sequela of pulpal necrosis due to dental caries or trauma. Clinically and radiographically, these cysts mayic other lesions, especially dentigerous cysts, leading to diagnostic challenges in mixed dentition. The article discusses a case of an infected radicular cyst linked to a deciduous cond molar, which on radiographic examination appeared similar to a dentigerous cyst associated with the developing second premolar.
