Dental manifestations in severe combined immunodeficiency following bone marrow transplantation

Severe combined immunodeficiency (SCID) is a rare primary immunodeficiency disorder with an estimated overall frequency of 1 in 75 000 live births. Bone marrow transplantation is the only curative treatment available. Using T cell-depleted HLA non-identical bone marrow requires preconditioning with a short course of cytotoxic chemotherapy. We report severe dental developmental anomalies in three such patients under long-term follow up.
