| 内容記述 | Using 103 students of the Matsumoto Dental College, variations in the protostylids and buccal pits, as they appeared in the lower permanent molars, were observed. Results as follows. 1. The protostylid occurred in 1 case (0.76%) on each side of the lower first molars. This frequency is a little lower than is found in the American White, and much lower than is found in the Pima Indian. 2. The buccal pit accounted for 65% of the lower first molars, and 20% of the lower second molars. The frequence of the buccal pit in the lower first molars of Japanese people is lower than that of the American White, and greater than that of the Pima Indian, and Indian (Hindu). The frequence of the buccal pit in the lower second molars of Japanese people is lowest. 3. The buccal pit is decreasing from the lower first molar, through the sequence of the second and third molars. This pit is a rare occurrence in the latter teeth, when such a pit is absent on the lower permanent first molars. 4. The pit was observed in 1 case beneath the distobuccal groove of the lower first molars. 5. The pit occurred in 1 case, on the distal half of the buccal surface of the lower second molars, and the groove occurred in 1 case, on the mesial half of the buccal surface in the lower first molars. | |||||||
