A total of 164 teeth in Indians, comprising 86 upper molars and 78 lower molars have been examined, and the occlusal surface indices have been calculated in order to compare the results of the previous studies. Our findings are as follows. The occlusal surface indices of the molars in Indians show a tendency of decreasing their values toward the posterior, that is, with the largest values on M1 and the smallest on M3. A statistically very significant difference has been observed between M1 and M2 and between M1 and M3 on both the upper and the lower jaws. The tendency mentioned above is seen with Australian Aborigines and Japanese. It is noted that the occlusal surface indices of Indians for each of the teeth examined are smaller than those of Australian Aborigines and Japanese.
