The author had tried to identify the sex from single tooth by detecting F-body of Y-chromosome in the nucleus of the dental pulp cells of 70 persons aged from 4 to 61 years under a fluorescent miscroscope.
The results were as follows.
1. In the cell nuclei of finale and female dental pulp at refrigeratory, the rate of F-body ap
pearance ranged 42-86% (average 61.06%) in male, while it was 0-6% (average 1.86%) infemale, indicating that male could be distinctly differentiated from female by F -body.
2. With male and female dental pulp putrefied by leaving it at room temperature, the rate of F-body appearance ranged 35-58% (average 48.20%) in male, 1-3% (average 1.70%) in female,indicating that it was possible to distinguish male and female by F-body.
3. Even in heat-treated male teeth at 100°C, 10 mina, the rate of F-body appearance proved to be 32-56% (average 42.50%), also indicating the possibility of identifying male.
4. When detecting of F-body in process of time, the rate of F-body appearance did not show major changes.
5. It was reaffirmed that F-body detection method was a positive determination method of male.
