摘要:

AbstractThe purpose of this double blind clinical trial was to determine the anticaries activity of a dentifrice containing 0.78% sodium monofluorophosphate in a silica gel abrasive base compared with a placebo under conditions of supervised brushing. 1154 schoolchildren, ages 9–12, were recruited in a non‐fluoridated semi‐rural area of northeastern Connecticut. Subjects were stratified according to school, grade and sex, and then randomly divided into two groups. Each school day, children brushed their teeth for 1 min under supervision by project personnel. Weekend and vacation usage was ad libitum. Caries examinations and radiographic readings were performed by the same examiner (J.R.). After 12 months, the 996 subjects examined showed that the group using the test dentifrice had significantly (<0.05) lower DMFT (25.0%) and DMFS (19.1%) increments than the group using the placebo. After 24 months the 876 subjects examined showed that the test group continued to have significantly lower DMFT (24.5%) and DMFS (24.7%) increments than the placebo group. Surface protection after 24 months ranged from 22.1% for occlusal to 37.1% for interproximal sur

摘要:

AbstractSixty percent of the population of the Republic of Ireland live in communities served with fluoridated water supplies. A study was carried out to compare dental caries levels, treatment needs, and the cost of meeting these needs, in one town with fluoridated water supplies and two smaller towns without. In the fluoridated town 5‐yr‐old children had 36% less caries and would cost 29% less to treat than the corresponding age group in the non‐fluoridated towns. Restorative treatment levels in both areas were minimal for this age group. In the 11‐yr‐old children there was a 42% difference in DM FT and a cost saving in treatment required because of caries of 50% in favour of the fluoridated community. Anterior permanent teeth benefited most, with a reduction of 81% in mean DMFT. In both areas most of the decay was seen in the permanent first molar teeth. Restorative treatment levels, while higher for the 11‐yr‐old age group, were still u

摘要:

AbstractA 5‐yr double‐blind fluoridated milk study has been completed and, following baseline stratification, 94 children aged 4 1/2 / 5 1/2 yr were allocated to the lest group and 93 to the control. Each subject received 200 ml school milk daily, identification between the test and control plastic packs being by colour‐coding alone with (he former containing 1.5 mgF‐giving a potential topical benefit of approximately 7 ppm F‐per school day. After 5 yr, 50 of the test children remained and 56 of the controls. While the mean DMFT incremental data relating to permanent teeth was always in favour of the test group, it was not until the fourth year that a significant difference was obtained (P<0.01) between the fluoridated group (mean, 1.65) and the non‐fluoridated group (mean, 2.56). For permanent teeth which were unerupted at baseline, the mean DMFS differences increased to 39.6% at the same time and to 48.0% by the fifth year. No benefit was noted for previously erupted primary teeth. Cavitation was less in the test group throughout the study. When the third, fourth and fifth year DMFT reductions obtained were compared with previously published artificial water fluoridated data where children were of comparable age at the onset of water adjustment, similar caries inhibition data

摘要:

AbstractThe effect of an annual application of an F‐lacquer on dental caries was investigated in a 3‐yr study. Two groups of children 10 and 12 yr of age at baseline were examined. Al the end of the study no significant difference in DMFS could be detected between test and control group. The following factors might have affected this negative result: firstly, the use of other forms of F‐supplementation, secondly, the relatively low caries experience in both groups and thirdly, the frequency and mode of application of the F‐

摘要:

AbstractA rural dental program located on La Gonâve, an island near the coast of Haiti is described along with demographic characteristics of the local population. The oral health of 61 adolescents and young adults seen during screening examinations was assessed. Caries free individuals made up 14.8% of the population. The mean DMFT for the group was 4.20. The OHIS score for the sample was 1.35; the PI score was 0.39. No significant association was found between DMFT, OHIS, PI and sex. One subject had a PI score 5.8 standard deviations from the mean score for the group and exhibited signs suggesting juvenile periodontitis

摘要:

AbstractPolicymakers face the problem that virtually no standards are available to judge whether the amount of dental care provided is satisfactory or to weigh the interests of dental care against other health and economic interests. It is suggested that international comparison of a number of standardized indicators and analyses of their development over time constitutes a practical approach to the partial solution of these problems. A specific set of basic data and seven indicators are suggested. Of the indicators, two serve as measures for the total volume of dental care available to the individual, two could help to assess the productivity of dental care workers, and three are intended to put the expenditures for dental care in the perspective of health care expenditures in general and the national economy at large. The practicality of the approach is subsequently demonstrated by the comparison of the basic data and the indicators for the Netherlands and the USA over the period 1972 through 1979.

摘要:

AbstractDental health practices among Finnish university students were studied in 1980. In order to obtain more information about the factors associated with different health status this problem was studied using linear discriminate analyses. 360 students were separately classified into fifths according to increasing individual VPI, GBI and DMFS index scores. According to the classification, the students of the two first fifths with lowest mean index scores were combined in the positively health oriented group. The students with low VPI and GBI index scores reported that they brushed their teeth most frequently. Also the good results of the dip‐slide method for counting salivary lactobacilli correlated well with the low VPI and DMFS index scores. In the discriminate analysis toothbrushing frequency was the most important single variable related to a good VPI score. By a computer method, 64% of the students were found to be correctly placed in the group of the positively health oriented. The corresponding percentage for the negatively oriented was 69%. The most important single variable related to good GBI and DMFS scores was subjective estimation of condition of dentition. According to GBI score the method correctly placed 57% of the students in the group of the positively and 69% in the group of the negatively health oriented. The respective percentages for DMFS‐index were 65% and 68%. The predictor variables failed to make an important contribution toward explaining the great variations in the oral health status indicat

摘要:

AbstractIn order to study the relationship between regularity of dental attendance and the value attached to the retaining of the teeth, a survey has been carried out among 25‐yr‐olds in Amsterdam. The value attached to retention was operationalized threefold and was analyzed with, among others, principal component analysis for discrete variables (HOMALS). It has been found that regular dental attenders, compared to irregulars, give a higher priority to retention of the teeth than to other items, are willing to spend a larger amount of money to prevent loss of the teeth, and have a greater aversion to full dentures at both the present age and when 50 yr old. These findings are discussed. Bused upon measures of association between the three operationalizations of the value attached to retention of the teeth, it is suggested dial these operationalizations deal with different aspects of the altitude towards full dentu

摘要:

AbstractThe purpose of the present study was to determine the distribution and the prevalence of periodontal disease in adolescents and adults using the WHO method TRS 621 and to propose a method of presenting the results by a simple index system. On the basis of a medium term longitudinal 5‐yr project 1048 subjects were examined in age group 1 (15–19 yr) and 425 subjects in age group 2 (35–44 yr). Each subject had a full mouth examination for the presence of supra‐or subgingival calculus, pocketing, bleeding and recession and the PI (Russell). These epidemiologic data were characterized by the ratioGingivitis: Periodontitis: Missingteeth by using solely the recordings for bleeding, pockets and missing teeth. The mean GPM index in Group 1 was 15.4:0.6:0.8. The mean GPM index in Group 2 was 12.0:4.6:7.7. The Periodontal Index is more subjective than the TRS 621 method. Full mouth recording is required for the suggested GPM/T index analogous to the DMFT index. This new scoring ratio makes it possible to present data of the progression rate of periodontal disease by the increment of tooth related P/T and M/T. Both indices with the common M‐value (Missing) might be used for longitudinal programs of control and prevention of periodontal disease and dent

摘要:

AbstractTiming and sequence of eruption of primary teeth were studied longitudinally in 164 healthy Australian children. Eruption of primary teeth typically began between 7 and 8 months and was completed by 28 months. Tooth eruption was not significantly related to growth rate or to psychomotor maturity. Comparison of the eruption ages in this study with those from longitudinal studies in other countries suggests that no real changes in these have occurred over 40 yr despite increased affluence in industrialised countries over that period.
