ABSTRACT Recent data have suggested that the trend of decreasing caries experience in Australian children is slowing with increasing dmft and DMFT scores seen in children. However, there are limited data on dental caries experience in young Australian adults.
A cross-sectional study of 973 Australian Army recruits was conducted between November 2002 and March 2003. A clinical examination with bitewing radiographs was conducted and a questionnaire was used to elicit socio-demographic information.
Mean DMFT scores were 2.43, 3.44, 5.48, 7.02 and 10.77 for subjects aged 17-20, 21-25, 26-30, 31-35 and 36-51 years respectively. Subjects with a lifetime exposure to fluoridated drinking water had a mean DMFT of 2.80 while subjects with no exposure to fluoridated drinking water had a mean DMFT of 3.91. Multivariate Poisson regression found that age, level of educationand lifetime exposure to fluoridated drinking water had a statistically significant effect on caries experience.
It appears that there has been a continual decline in caries experience and prevalence in young Australian adults between 1996 and 2002-2003. Lifetime exposure to fluoridated drinking water conferred an appreciable benefit for subjects in this study compared with subjects with no exposure to fluoridated drinking water.

    ABSTRACT: The purpose of this investigation was to test the safety and clinical effect of a new material for the treatment of proximal caries. In 50 patients with two proximal initial lesions, one of the lesions was randomly chosen and sealed with a thin polyurethane-dimethacrylate foil using bonding. The other lesion received oral home care and was left as the control. In clinical follow-ups after 6 and 12 months and X-ray evaluation after 2 and 3 years, the sealants showed good retention, marginal adaptation, and color. No relevant significant differences in plaque accumulation or gingival status were found between sealed and control teeth. On the radiographs, almost all sealed and control lesions appeared stable, indicating an arrest of the lesion. In conclusion, sealing initial proximal lesions showed no clinical problems and mostly arrest of caries on bitewing radiographs.

    ABSTRACT: Dental caries has multifactor origins and socioeconomic conditions are part of this context. The aim of this study was to determine the prevalence of caries and investigate its association with socioeconomic variables among young male conscripts aged 17 to 19 years in Manaus, Amazonas. This was a cross-sectional study using a convenience sample of conscripts of the Brazilian armed forces. Diagnostic criteria and the socioeconomic questionnaire were based on the SB Brazil national survey and WHO criteria. A single examiner (kappa = 0.96) performed oral examinations on 578 conscripts. The Shapiro-Wilk test was used to verify normal distribution, and for non-normally distributed data (p = 0.0001), the nonparametric Kruskal-Wallis test was used to compare means. Any significant differences in the DMFT index and its components, relative to the variables evaluated, were investigated. The prevalence of caries was 88.8% and the mean DMFT index was 5.16 ± 0.17. Statistically significant differences were found in the means for decayed, missing and filled components of the DMFT index. Worse indicators were found in groups with lower schooling, lower income, and from public schools, thus demonstrating the need to improve prevention and care for these groups.

    ABSTRACT: To review the effectiveness of adjusted fluoridation of public water supplies in the prevention of dental caries, with emphasis on results of studies published worldwide since 1990 and to discuss aspects of the design and reporting of these studies compared with those published before 1990. Studies published worldwide, in any language, reporting the effect of water fluoridation in terms of the dmf/DMF caries index between 1990 and 2010 were examined. The literature search was by professional Internet search, back-tracking from references given in publications, hand-searching all issues of four journals and by contacting colleagues in relevant countries. For the dmf index, age 5 year was preferred, and for the DMF index, age 12 year or older was preferred. The results were compared with results obtained from worldwide literature search prior to 1990 by the same author. Fifty-nine studies of adjusted water fluoridation were identified, yielding 83 evaluations (30 recording dmft/s and 53 recording DMFT/S) from 10 countries. These numbers are lower than pre-1990 results of 113 studies (66 for primary and 86 for permanent teeth) from 23 countries. For the USA, for example, four studies were indentified since 1990 compared with 61 studies before 1990. The most number of recent reports came from Brazil and Australia. There were fewer reports of per cent caries reductions (% CR) above 50% in the recent studies. 86% of the post-1990 investigations were concurrent control cross-sectional studies and, of these, 52% used multivariate statistical analysis to adjust for confounding factors. In the eight studies that provided dmf/DMF data before and after adjustment for confounders, the % CR were little affected by these adjustments. Fewer studies have been published recently. More of these have investigated effect at the multi-community, state or even national level. The dmf/DMF index remains the most widely used measure of effect. % CR were lower in recent studies, and the 'halo' effect was discussed frequently. Nevertheless, reductions were still substantial. Statistical control for confounding factors is now routine, although the effect on per cent reductions tended to be small. Further thought is needed about the purpose of evaluation and whether measures of effect and study design are appropriate for that purpose.
