Abstract

Background: Human Severe Combined Immunodeficiency (SCID) is a prenatal disorder of T lymphocyte development that depends on the expression of numerous genes. Juvenile myelomonocytic leukemia (JMML), previously known as juvenile chronic myeloid leukemia (JCML), is a rare, myelodysplastic/ myeloproliferative disease typically presenting in early childhood. Case Reports: Two cases are described of immunodeficiency disorders, both treated with chemotherapeutic drugs (Busulfan plus cyclophosphamide) before bone marrow transplantation. After treatment, these two different cases showed several similar oral lesions: microdontia, root alterations, numerous tooth ageneses, incomplete calcification, enamel hypoplasia, premature apexification and hypodontia. Both subjects underwent dental and orthodontic treatment. The first phase comprised orthopaedic treatment using a removable appliance (Interim-G®) followed by rapid palatal expansion; in the second phase patients underwent tooth extraction and were treated using fixed appliances for 19 and 26 months, respectively (mean 2 years) to obtain final alignment and maximum intercuspation. In the third and final phase, reconstruction of malformed teeth was completed, and implant-supported protheses were applied. Conclusion: The difficulties of managing and treating these diseases are discussed, with particular focus on tooth anomalies and malocclusion disorders. Collaboration between dentist and paediatrician in dealing with patients with a variety of oral lesions and tooth anomalies is important in order to prevent any other possible tooth lesions and ensure correct jaw development.
