Oral condition in children treated with bone marrow transplantation.
Oral health was studied in 49 children below 12 years of age treated with bone marrow transplantation (BMT). Dental treatment prior to BMT was required in 41% of the children. Ulceration of the mucous membranes in the mouth was observed in 37% of the patients during treatment. Those given methotrexate as prophylaxis against graft-versus-host disease (GVHD) exhibited oral ulcerations more frequently (p less than 0.05) than those given cyclosporin. One year after BMT all patients with a clinical chronic GVHD exhibited changes in the oral mucosa. During the first year after BMT 31% of the children developed carious lesions. Children treated with 10 Gy total body irradiation (TBI) had a significantly (p less than 0.05) reduced salivary secretion rate. Dental development was severely affected in children treated with TBI. These disturbances consisted of arrested root development, enamel hypoplasias and microdontia.
