“…DMFT scores in 12-year-old children have also been reported for Finland (2.2) (Luoma and Ronnberg, 1987) and for Italy (3.03) (Giannico, 1987). In Hamburg, in the same age group, a DMFT score of 6.33 was found by Franz and G6tze (1983).…”

National Survey of Caries Prevalence in 6-15-year-old Children in France

et al. 1989

The prevalence of dental caries in France is not known on a nationwide basis, despite the fact that a number of epidemiological studies have been conducted in various parts of the country. The aim of the present study was to provide a national baseline examination of the dental health of children in 1987 since, beginning in November, 1986, the sale of fluoridated salt began in France. A multi-stage probability sample of 19,366 children was selected as representative of the 6-to-15-year-old population. The sample covered all the 95 departments of France. Teams of well-calibrated examiners were constituted in each of the sixteen Faculties of Dental Surgery of France. The prevalence of caries for each age group was determined by means of DMFT, DMFS, dft, and dfs indices. Periodontal conditions were assessed by means of the Plaque Index (Silness and Löe, 1964), the Calculus Index (Marthaler, 1966), and the Gingival Index (Löe and Silness, 1963). Calculation of the mean DMFT index showed, respectively, 0.5 and 1.0 new carious teeth per year under and over the age of 11. The mean values of the DMFT index at ages 6, 12, and 15 were, respectively, 0.5, 4.2, and 6.9. Under the age of 11, the mean DMFS index increased by one between each successive age group and by nearly two over the age of 11. The mean values of the DMFS index at ages 6, 12, and 15 were, respectively, 0.8, 7.6, and 13.0. The percentage of caries-free children decreased from 32.2% at age 6 to 7.9% at age 15.

“…According to Schwarz (1987), 54% and 16%, respectively, of Danish children were caries-free at the ages of 5 and 12. Reporting the results of a 12-year prevention follow-up of Finnish children, Luoma and Ronnberg (1987) observed that, initially, only 10% of the 6-year-old children were caries-free; this percentage was 57% 12 years later.…”

“…Official statistics and research reports have shown an appreciable decline in the occurrence of past and present caries in recent years in Finland [Rytomaa et al, 1980;Milen et al, 1986;Nordblad, 1986], A report from the health centre of the city of Espoo in southern Finland stated that teenagers in 1984 had about 6 DMF teeth and 1 decayed tooth (DT) less than similar teenagers 10 years earlier [Luoma and Ronnberg, 1987], Similar trends in caries prevalence in children and adolescents have been reported for many industrial ized countries [Graves and Stamm, 1985;Bille et al, '986;Birkeland and Bragelien, 1987;Hargreaves et al, 1987;Hailing and Birkhed, 1988;Carr, 1988]. Most reports have dealt only with the mean value of DMFT and its components.…”

This study investigated the occurrence of caries among 15-year-olds using the municipal oral health service in Helsinki in 1976 and in 1986. Data were collected from each subject’s personal dental health file as recorded during routine check-ups by dentists in the health centre of the city of Helsinki in the year in question. All indicators showed a significant improvement (p < 0.001) in dental health during the 10-year period. The percentage of intact teeth and surfaces increased markedly. The mean number of DMF teeth per person fell from 12.1 to 5.1 and that of proximal DF surfaces from 5.6 to 1.5. In the 1976 group, 63% of all occlusal surfaces had been filled or were decayed. Ten years later the figure was 26%. Proximal DFS percentages were 10 and 3%, respectively. The ratios of the total number of proximal to occlusal DFS were 0.6 in 1976 and 0.4 in 1986.

“…The 14-year reductions are consistent with a prop- agation of the 7-year cumulative effects observed, with the observed 55% reduction slightly larger than the 45 or 49% expected values one would obtain from the CGM or DSR model. A report of 12-year follow-up for Finnish subjects by Luoma and Ronnberg [14] was published in 1987. Their findings are summarized in table 7.…”

Methods of Projecting Long-Term Relative Efficacy of Products Exhibiting Small Short-Term Efficacy

There is ample evidence that caries can develop well into the middle-aged years, and for many subjects, for most of their adult lives. The kinds of benefits to expect for adults in the longer term for improved fluoride products, especially dentifrices, based upon small observed relative improvements in short-term efficacy is a topic currently of considerable interest. For example, what longer-term benefits can be expected by the continued use of an improved fluoride dentifrice, corresponding to an observed 5 % or 10% short-term improved efficacy relative to a positive control product? In this study, three models are presented and discussed for projecting longer-term relative benefits of fluoride products for which valid short-term efficacy estimates are available: the compound growth model (CGM), which is a derivative of the compound interest model; the demineralization square root model (DSR), used in demineralization-remineralization studies, and the stabilization model (STA), which is based on the assumption of constant caries attack rates. Published results from long-term studies of fluoride dentifrices and other topical fluoride products (rinses and tablets) suggest that anticaries benefits for topical fluorides do propagate over time, providing increased relative benefits to patients in the longer-term, as compared with the benefit estimates from short-term clinical experiences. In general, these results suggest that some combination of the CGM and the DSR models most adequately describes the expected propagation benefits of topical fluorides, provided the anticaries effects of the product are not ‘saturated’. Expected 10- and 20-year estimated cumulative relative efficacy figures are derived for improved dentifrice products having small short-term efficacy values separately for the CGM, DSR and STA models. A dentifrice having an observed improved efficacy of 5% relative to a positive control product would be expected to produce a cumulative 10-year relative benefit between 9% (DSR) and 15% (CGM); over a 20-year period a cumulative benefit between 13% (DSR) and 28% (CGM). The actual values may depend upon the dose of the fluoride administered and other factors.
