Which type of cyst is most commonly associated with Rushton bodies?

Rushton bodies are specific structures found within the histological examination of radicular cysts, which are the most commonly associated type of cyst with these bodies. Radicular cysts, also known as periapical cysts, typically arise at the apex of a non-vital tooth due to pulp necrosis and are lined by stratified squamous epithelium. Within these cysts, Rushton bodies—characterized by their clear, eosinophilic contents resembling amorphous keratin—can often be identified.

The presence of Rushton bodies can help in the identification and diagnosis of radicular cysts, providing insights into their pathologic nature. This association is significant from a histopathologic standpoint, as it reinforces the connection between the underlying etiology of the cyst and the cellular features observed within it.
