JOURNAL FREE ACCESSI investigated the mouth of the 70 feeblemindedness-girls and boys who were 5-19 years old and I.Q. 16-74.
They were not up to census age in physical strength and mental activity, I found the many odontoloxia, abnomal bites and malformed teeth in the mouth, but it is 70.58 % in their teeth caries morbidity, this percent is more reduced than the other reports', and I found just only 2.02% handicap between the caries morbidity of the general cildren and their.
I think, it has its source in the their food and an effect of the oral cleaning guidance over a 6-years period.
About the relation between intelligence quotient and tooth caries, I think, the reason why the inferion have many caries is due to their dull sense of the oral hygiene rather than inheritance or constitution, and if we gave a good lead to them, they would have a keen sense of oral, even if they were the inferior, and their caries morbidity will go down as a general health children.View full abstractDownload PDF (1087K) -

JOURNAL FREE ACCESSWe have made dental examination of the infants in Gifu with the following result.
(The object for our examination is 3, 221 infants containing 1, 699 males and 1, 522 females.)
1. Milkteeth erupt earlier in proportion to infants'body-weight at the time of birth.
2. The eruption of milkteeth is affected by the way of feeding; mixed feeding erupts first in earliness, suckling feeding second and artificial feeding last.
3. Milkteeth erupt in 7.31±0.61 months, on an average (in 7.24±0.06 months in the case of males and in 7.34±0.07 months in the case of females), and the milkteeth of males erupt earlier than those of females.
Normal eruption is 79.3 percent, earlier eruption is 19.2 percent and later eruption is 1.5 percent. Earlier eruption is more freqent in our examination than in the other reports.
4. The average number of erupted teeth has no relation to the body-weight at the time of birth, but is larger in proportion to the increase of body-weight.
The examination of those who belong to one and same group in the increasing rate of body-weight shows us that milkteeth tend to erupt at the same rate of earliness, irrespective of the various body-weight at the time of birth.
5. Milkteeth erupt earlier in proportion to the statue, body-weight and girth of the chest of infants.View full abstractDownload PDF (1447K) -

JOURNAL FREE ACCESSFor the purpose to reveal the relation between the oral symptoms in periodontal disease and the systemic facto rsrepresented by clinico-chemical tests, an attempt was made to find out a more precise index for periodontal symptoms based on the Russell scoring system.
The periodontal index suggested by Russell appeared to have a great significance for epidemiological study of periodontal disease in population as compared with other scoring method. In Russell index, however, the total prevalence of periodontal disease is materially underestimated as pointed out by Ramfjord who attributed its reasons to inadequate examination procedures, or the igorance of the intensity or extension of periodontal disease. Therefore, the trial was made to improve the incompleteness involved in Russell index and consequently new two indices were introduced: one is“Intensity index”, the other is“Extension index” as beeing defined by the author as follows.
Total scores on the individual person was computed similarily as the Russell's index method. The total sum divided by the numbers of the suffering teeth gives“the intensity index”, while the numbers of suffering teeth divided by the numbers of teeth examined makes“the extension index” .
Using new indices and the original Russell index together, it becomes more clearly and easily to classify various types of clinically complicated periodontal symptoms.View full abstractDownload PDF (1085K) -
Pert II. Correlation of the clinico-Chemicaltests and Russell Scores of Oral Symptoms in Periodontal DiseaseToshibumi ISHII, Shigeru YOSHIDA, Daihatsu KOTANI, Tatsuo SASAKI, Tosh ...1963 Volume 13 Issue 3-4 Pages 121-130

JOURNAL FREE ACCESSIt is generally acknowledged that the systemic factors may play a significant role in periodontal disease, although the actual factors influencing on the periodontium have not yet clearly demonstrated, so that it is hoped for the present to accumulate as much objective data as possible available for establishing the correlation between periodontal and systemic signs. For this purpose, the periodontal symptoms involved should be defined clearly in order to be comparable with other similar independent studies.
In the first paper, therefore, it was reported that the grade of the severity in periodontal diseases was better illustrated with“Russell index”, “Intensity index”, and “Extension index” based on the Russell's scoring system.
This paper reports the correlation between the clinico-chemical tests representiong systemic factors and the oral involvement as classified according to three indices mentioned-above. The clinico-chemical tests involved eighteen kinds of tests in blood and urine.
Almost all of the chemical results remained within the normal range of variations, but there was a trend that the more abnormal was the chemical results, the more severe the oral symptoms appeared.
It was interesting to find that the concentration of γ-globulin fraction in blood was elevated higher in the extensively suffering cases than in other cases when observed at the level 1.0 to 2.9 of “Intensity index”.View full abstractDownload PDF (1185K) -

JOURNAL FREE ACCESSFluorine contents and total hardnesses of municipal water supply in 102 principal cities in Japan were determined by SPADNS-zirconium method and EDTA method.
1) Fluorine contents of water ranged generally from 0.05 to 0.2 ppm. Cities with common water supply containing over 0.2 ppm of fluorine were; Kumamoto (0.23), Toyonaka (0.27), Tsushima (0.29), Takarazuka (0.32), Kyoto (0.62-experimentally fluoridated-Yamashina area) and Kasaoka (1.2-1.3 ppm).
2) Total hardnesses of water (expressed as CaCO3) ranged generally from 40 to 100 ppm; most of them appeared to belong to soft water. In some cities, total hardnesses were above 250 ppm, e. g. Mobara (256.7) and Kasaoka (280.3ppm). Itoigawa was supplying moderately hard water (184.1 ppm) and there were eleven other cities distributing slight hard water (100-150 ppm).View full abstractDownload PDF (1038K)
