The fluoride concentrations on the buccal surface increased transiently after eruption and then decreased. The decrease of fluoride concentration appeared to be most remarkable near the biting edge of the buccal surface in earlier stage.3) The differences in the fluoride concentrations between the approximal surfaces and the buccal surface in the group of unerupted teeth were not significant, but in the older group the approximal surface showed significantly higher fluoride concentrations than the buccal surface.4) The gourp of unerupted teeth showed significantly lower fluoride concentrations than the: group of erupted teeth, and the most scattered value of all.5) Enamel solubility tended to decrease first and then to drop to a plateau shortly after eruption.6) There were no differences in the enamel solubility between the approximal surfaces and the buccal susface, but in the older group the approximal surface. showed lower enamel solubility than the buccal surface.7) The group of unerupted teeth showed the least scattered values of all in the enamel solubility. The enamel solubility of the approximal surfaces tended to be more dispersed than that of the buccal surface.8) There was a reverse relationship between fluoride concentration and enamel solubility.","PeriodicalId":76075,"journal":{"name":"Koku Eisei Gakkai zasshi","volume":"55 1","pages":"64-81"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74588277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were made in vitro by applications of phosphoric acid-acidified NaF solution (500 ppm of F-; pH 5.0) to the intact enamel.The distribution of fluorine, calcium and phosphorus in enamel following the topical fluoride treatment (30 minutes every day for 8 weeks) were demonstrated by electron probe microanalysis.X-ray diffractometry was performed by the use of X-ray microfocus diffraction. Reaction roducts and crystallinity of the enamel were observed in the X-ray diffraction pattern obtained with a microphotometer. The variation of crystallinity was estimated from the half-maximum breadth values (310), (002) reflections of enamel apatite.Electron probe microanalysis shows that the fluorine concentration of surface enamel was increased not only on flat surfaces but also in fissure areas by the repeated use of fluoride mouthrinsing solution. Espeiaclly high concentration of fluorine was observed at the subsurface decalcified area of the enamel surface.In the X-ray diffraction experiments, no reaction product was detected. The crystallinity of enamel apatite of the surface layer was increased in both a- and c-axis directions by application of fluoride mouth-rinsing solution. In the inner layer it seemed that the crystallinity of enamel apatite in the a-axis was also increased by the use of fluoride mouth rinse.","PeriodicalId":76075,"journal":{"name":"Koku Eisei Gakkai zasshi","volume":"18 1","pages":"98-103"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75459966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[On the relationship between deciduous tooth eruption and the stature and weight of infants].","authors":"Y. Endo","doi":"10.5834/JDH.30.85","DOIUrl":"https://doi.org/10.5834/JDH.30.85","url":null,"abstract":"There is a fairly large body of literature concerning the influence of bodily growth and environmental factors on the eruption of teeth in man. However, studies dealing with tne correlation detween the number of erupted deciduous teeth and the value of bodily growth are comparatively scanty. In the present work. I studied the correlative coefficients of the stature, weight, weight ratio, and increasing rates of both stature and weight in an effort to elucidate the relationship between these body factors and deciduous tooth eruption. By way of study materials, a selective use was made of 5, 119 boy and girl infants of 5 to 18 postnatal months, who were reared in more or less the same family circumstances. At the same time, observations were made of differences, if any, between the firstborns and second-borns. As a result of the study. I arrived at the following conclusions:1. Stature, weight, and their increasing rates. In these categories, boys showed a tendency to be larger than girls in corresponeding postnatal months. The difference became statistically significant after 8 postnatal months. In terms of stature, there was a tendency for the firstborns to be somewhat larger in both boys and girls. 2. Weight ratio. Boys showed a tendency to be laerger than girls in corresponding postnatal months. The first-born group also tended to be laerger. 3. In the number of erupted deciduous teeth, boys showed a larger count than girls after 10 postnatal months. The first-born group showed a larger number of erupted deciuous teeth than the second-born group. 4. In the correlation fetween the number of erupted deciduous teeth and stature and weight, the correlative coefficients became larger in proportion to the postnatal months, but statistical difference was absent in every group. An absence of statistical difference was also seen between the first-born and second-born groups. 5. In the Number of erupted deciduous teeth and increasing rates of stature and weight, boys and girls gave a significant correlation after 6 postnatal months. There was no significant difference between the first-born and second-born groups in either sex. 6. In the correlation between the number of erupted decidous teeth and the increasing rates of stature and weight, the increasing rate of stature was most closely related, followed by the present stature, increasing rate of weight, and present weight in descending order. Therefore, I conclude that there exists a close relationship between the deciduous teeth eruption and the amount of physical growth of infants.","PeriodicalId":76075,"journal":{"name":"Koku Eisei Gakkai zasshi","volume":"58 1","pages":"23-40"},"PeriodicalIF":0.0,"publicationDate":"1980-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80010091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
