Dentists are responsible for the diagnosis of abnormalities involving both hard and soft tissues in and around the oral cavity. In addition to a clinical examination, the radiographic evaluation will often highlight abnormalities within the radiographic field. A relatively uncommon radiographic abnormality is calcification of lymph nodes, which may be associated with a number of pathologic processes, both local and systemic. We present and discuss lymph node calcifications and the diagnostic considerations associated with them in order to assist practitioners in managing their patients appropriately.
