Dental problems caused by radiation, chemotherapy should be treated before a child undergoes immunosuppression as part of bone marrow transplantation therapy

Many children who undergo bone marrow transplantation (BMT) as part of cancer treatment already have dental abnormalities that leave them vulnerable to potentially life-threatening bacterial infections, according to investigators at St. Jude Children's Research Hospital. A report on this study appears in the prepublication online edition of Bone Marrow Transplantation.
