摘要:

abstract–It is widely recognized that oral health has its major obstacles in the form of dental caries and periodontal diseases and that in many populations each of these disease areas attacks nearly 100% of the population during the normal life span. Furthermore, there are clear signs of sharp increases in the dental caries problem in populations which previously benefited by a near absence or low prevalence of the disease. For highly developed countries dental caries and periodontal disease are responsible for an ever increasing economic burden which could easily become intolerable for even the richest of economies. In developing countries where dental caries prevalence is increasing the extreme lack of manpower resources is the first barrier, any response to which will encounter the second and associated economic constraint. It is essential for both situations that greater emphasis be given to prevention of oral diseases both by methods already proven, such as fluoridation of water supplies and other uses of fluorides, by oral hygiene programs, and by coordinated research to develop complementary or other methods. The WHO program in oral health has now developed a priority activity to promote and guide such endeavor

摘要:

abstract–The saliva and plasma fluoride (F) concentrations following intake of different doses of fluoride tablets were studied in six subjects. There was a close relationship between saliva F and plasma F and the ratio was 0.64±0.01 (s.e.). The plasma half life of F was 4—16 h. This results indicate that saliva F may be a useful substitute for blood sampling in studies concerning the pharmacokinetics of fluo

abstract–The ion probe technique has been employed for the determination of the concentrations of P, F, Cl, C, Na, K, Mg, Sr, Al, and Si at different depths in human tooth. The applicability of the method depends selectively on the element's position in the periodic table, but may be regarded as good for a wide range of microelements of dental interes

摘要:

abstract–A study of enamel fluorosis in 1,094 children was carried out in areas with a water fluoride content of from<0.2 mg/1 with and without supplementary fluoride, to 2.75 mg/l. The fluorosis was correlated with different infant diets and also with the calculated supply per kilo body weight. As in cattle, 0.1 mg F/kg body weight daily appears to cause fluorosis. This dose may for example be reached with water‐diluted gruel powder in low‐weight infants with high consumption in low F areas, in normal weight infants in 0.8 areas, and also in high‐weight infants in 1.2–1.5 areas. The resultant fluorosis is very mild or mild and not disfiguring. Enamel fluorosis can be avoided or minimized in areas with up to at least 1.2 mgF/1 water if F‐supply, e.g. water‐diluted gruel and/or supplementary fluoride, is not commenced until 6 months of age when body weight is higher. With a water fluoride content of 2.75 mg F/l a very mild fluorosis is difficult to avoid also with normal water consumption during the 1st

摘要:

abstract–This paper is based upon the mean annual amounts of fillings (filled surfaces) and the DMFS among 6/7‐ to 15/16‐year‐old children. Each age group comprised about 450 children. Cross‐sectional recordings were available prior to the start of a caries‐preventive program based on 2‐weekly fluoride rinses. Cross‐sectional and longitudinal DMFS recordings were different during the 10 years of observation. This indicates benefits exceeding the present 70% reduction in need for fillings and 50% improved caries prevalence. The ratio fillings needed for giving the DMFS score among 13‐ to 14‐year‐old children was found to improve from 1.60 to 1.16. Based on the cumulative amounts of fillings and the ratio of fillings DMFS, a DMFS of 15 may be expected in 4 years among children 15–16 years old. This caries prevalence is not markedly different from DMFS recordings among Scandinavian children l

摘要:

abstract–The possibility of achieving a caries‐reducing effect by a combination of Fortnightly mouthrinsings with 0.2% NaF‐solutions and topical painting with solutions containing Al‐, Fe‐, and Mn‐ions was examined in a 4‐year clinical study. In addition to the fluoride rinses one of two randomized groups was given three paintings per year with a 0.2 % NaF‐solution. The other group was painted three times per year with a potassium fluoride solution containing Al‐, Fe‐, and Mn‐ions. This group developed significantly less caries during the study than the NaF‐group. The results indicate that certain metal ions enhance the caries‐prophylactic ac

摘要:

abstract–In a 3‐year clinical trial the effect of daily supervised toothbrushing with a dentifrice containing sodium fluoride/ silicon dioxide and a dentifrice containing sodium monofluorophosphateo/calcium phosphate and calcium carbonate was investigated. Initially about 400 children aged 9–11 years from one school in Malmö took part in the study. They were randomly divided into two groups. Each group brushed their teeth daily in school under the supervision of a dental hygienist. The children and their families were given the corresponding dentifrices for home use. The children were examined for caries at the start of the study and again alter an interval of 1 year by the same dentist and according to the stated criteria. A comparison of the caries increments in the two dentifrice groups revealed a statistically. Significantly lower caries increment during the 2nd and 3rd experimental years in the sodium fluoride dentifrice group compared with the sodium monofluorophosphate dentifrice

摘要:

abstract–As part of a clinical trial among schoolchildren in a suburban community just outside Oslo, dental preventive behavior was studied by means of mailed questionnaires, In all, 340 mothers, i.e. 95% of the sample, filled out and returned the forms. The results indicate a distinct and improving preventive attitude in the target population. The age of the family was the most influential background variabl

摘要:

abstract–The aim of this study was to develop a planimetric, automatic method for evaluation of the extension and volume of plaque. Series of color macrophotographs of stained plaque were analyzed with a digitizer entering Cartesian coordinate data from the graphic records in a calculator. Estimations were carried out on the reproducibility, discri minatory power, and time required for the planimetric analysis. In addition, the ratios between values obtained before and after reproducible cleansing were interpreted as measurement of the adhesion of plaquein viv
