Selection of allogenic tooth graft using HLA-A, -B, -C and DR typing and the MLC test

An allotransplantation of a partly developed premolar from a 12-year-old daughter to her mother is reported. The tooth graft was selected by the use of HLA-A, -B, -C and DR typing and the MLC tests. Follow-up over a 3-year period included periodic identically taken radiographs, electric and galvanic pulp tests and tests for cytotoxic antibodies. Almost complete closure of the apex of the tooth has occurred with no sign of root resorption. The transplant has remained vital, and no production of antibodies against the graft has occurred.
