In August to September of 1995 the authors conducted an anthropometry of the head and face and measurement of the dental arch on Chinese Liao-Ning (66 males and 83 females), and the results were discussed. Furthermore, the correlations between the measurements of head and face, and those of dental arches and palate height were studied. The main results obtained are as follows : 1) Head length : the mean value for the male is 181.0mm and for the female 170.4mm. Both belong to Middle type. 2) Head breadth : the mean value for the male is 155.3mm and for the female 151.6mm. Male belong to Middle type and females belong to Wide type. 3) Bizygomatic breadth : the mean value for the male is 140.3mm and for the female 133.5mm. Both belong to Middle type. 4) Morphological face height : the mean value for the male is 124.0mm and for the female 114.6mm. Both belong to High type. 5) The head-type of the Chinese Liao-Ning belongs to Hyperbrachycephalic type and the face-type to Leptoprosopic type. 6) Correlation : The significant positive correlation is noted between the morphological face height and lower dental arch length only in the male, while that between morphological face height and palate heght is noted in both male and female.

The author produced a measuring apparatus to determine the rate of tongue extension, which could show numerically the degree abnormality. Since the apparatus measures objectively, each observer could make comparative observations. By using this apparatus, investigations were made on the rate of occurrence of Tongue-tie among various groups of male and female junior high school pupils in Kumamoto Pref. The results obtained were summarized as follows. 1. A measuring apparatus for the tongue extension degree was produced, which could measure the value of both maximum spontaneous open mouth and maximum spontaneous tongue extension. (a) The value of maximum spontaneous tongue extension given by the measuring apparatus for tongue extension divided by the value of maximum spontaneous open mouth is the degree of Tongue-tie. (b) The degree of Tongue-tie is as follows. Male … less than 0.40. Female … less than 0.43. (c) Tongue-tie is classified into three degrees, 1°, 2°, 3° according to the relative severity. 2. The rate of occurrence of Tongue-tie is 9.7%. Out of 8767 pupils tested, 852 were founded to have the deformity. (a) There is no difference in the rate of occurrence between the sexes in each district. (b) There is no difference in the rate of occurrence among districts. (c) The rate of occurrence according to the degrees are as follows. 1°…8.77% 2°…0.86% 3°…0.09%
