272 members of the women's junior college students (18-20 years old) were employed in experiments. The occlusion forces of the 1st molars were measured by the method of transduser gnathodynamometer (Nihon Kohden MPM-3000). The following results were obtained. The maximum of occlusion force was 94 kg, the minimum of it was 1kg, and the meam value was 22.6 kg. Standard deviation was 11.64. On general, the occlusion force of the young women is estimated over 30 kg, and so the level of result obtained in experiments is seem to be very low.
