Effects of Community Water Fluoridation on Dental Caries Disparities in Adolescents

Despite improvements in the prevalence of dental caries, disparities are still observed globally and in the U.S. This study examined whether community water fluoridation (CWF) reduced dental caries disparities in permanent teeth of 10- to 19-year-old schoolchildren in North Carolina. We used cross-sectional data representing K-12 schoolchildren in North Carolina (NC) public schools. A poisson regression model was used to determine whether the association between children’s parental educational attainment and the prevalence of dental caries of children differed by children’s lifetime CWF exposure. We analyzed data on 2075 students. Among the children without any CWF exposure in their life, statistically significant caries disparities by parental educational attainment were observed. Compared to the children of parents with more than high school education, the relative risk for those with a parent with a high school education was 1.16 (95% CI = 1.01, 1.33) and those with less than a high school education was 1.27 (95% CI = 1.02, 1.60). In contrast, these disparities were not observed among children exposed to CWF throughout their lives. Socioeconomic disparities in dental caries were not observed among 10–19-year-old schoolchildren with lifetime CWF exposure. CWF seemed to reduce dental caries disparities.

Design of an innovative paediatric capitation payment approach for public sector dentistry: an Australian experience

AIM

The aim of this study was to trial the methodology and administration processes of a public paediatric capitation programme provided in the period 1 July 2011 to 31 December 2011 through a Bachelor of Oral Health programme in rural New South Wales (NSW), Australia, where access to public dental services is limited.

BASIC RESEARCH DESIGN

The principal structure of the programme was the development of three diagnostic pathways: active caries and pain (Pathway A); active caries and no pain (Pathway B); and no active caries and no pain (Pathway C). In 2011, de-identified treatment data for NSW public dental services' patients under 18 years of age were analysed to identify the top 10 dental treatment items. These items were clustered according to the mean decayed and/or filled surface of patients under 18 years of age who had decayed, filled or missing teeth. Each treatment item was allocated 60% of the 2011 Australian Government Department of Veteran Affairs Schedule of Fees.

CLINICAL SETTING

The programme was trialled in Charles Sturt University dental facility in Wagga Wagga, NSW.

PARTICIPANTS

The programme targeted patients in the following age groups: 0-5 years; 6-11 years; and 12-17 years.

RESULT

The 6-month trial provided 361 patients with a capitation pathway, at a total cost of $47,567.90, averaging $131.76 per capitation pathway. The total number of items provided (n=2,070) equated to an average of 5.7 items per capitation diagnostic pathway.

CONCLUSION

This model offered an early entry point for paediatric patients to access dental care that addressed their needs, whilst being flexible enough to be fiscally attractive.
