providing a personal information carrier having information carried by a radiopaque configuration which is radiographically readable by conventional dental X-ray technique;

securing the personal information carrier to an external and noninvasive portion of a tooth; and

concealing visually the personal information carrier.

28. The radiographically marking method of claim 27 in which the step of securing includes the step of etching the external and noninvasive portion of a tooth.

29. The radiographically marking method of claim 27 in which the step of securing includes the step of applying a resin layer to overlie the external and noninvasive portion of a tooth.

30. The radiographically marking method of claim 27 in which the step of securing includes the step of applying a layer of dental composite to overlie the external and noninvasive portion of a tooth.
