Analysis of DNA from tooth and application to forensic dental medicine.

The DNA extracted from teeth was examined to find out the usefulness in forensic dental medicine. Samples of tooth-derived DNA were digested with a restriction enzyme, electrophosed through agarose gel and subjected to Southern blot hybridization, using a 32P-labeled minisatellite DNA probe "Myo" and a Y chromosome-specific DNA probe. The results indicate that DNA extracted from dental pulp is useful for identification of individuals, paternity testing, and sex determination.
