Objectives To investigate signs of infection and infection-related complications of apical periodontitis (AP) in patients who underwent chemotherapy for lymphoma. Materials and methods Data were collected retrospectively from the dental and medical records of patients receiving chemotherapy for lymphoma. Based on the findings from a dental evaluation made in conjunction with chemotherapy, the patients were divided into two groups, patients with or without teeth with AP. Results Eighty-six of the 213 patients had one or more teeth with AP and received no planned dental treatment for this condition, while 127 patients had no AP-affected teeth. During chemotherapy, seven patients (8%) developed local symptoms related to teeth with AP, while no patients in the control group developed symptoms of AP. No significant differences were found with respect to the administration of antibiotics related to dental infection or hospital admission events due to fever or infection, between the group with AP and the group without AP. Conclusions AP is a common finding and exacerbation seems more common in patients diagnosed with chronic AP than in patients without chronic AP. The presence of chronic AP in patients treated with chemotherapy for lymphoma is not linked to additional medical complications that require hospital admission owing to fever/infection.
