Fluoride intake from beverage consumption.

Previous studies have shown that fluoride is present in beverages prepared with fluoridated water. The purpose of this study was to determine the availability of fluoride from beverages consumed in adjacent fluoridated and non-fluoridated communities taking into account fluoride supplementation regimens. Children in grade six were invited to participate in recording of beverage intake in two cities in Alberta, Canada: Wetaskiwin, with water supplies fluoridated at 1.08 ppm F, and Camrose, non-fluoridated with water supplies at 0.23 ppm F. Three-day beverage intake records--"Drink Diaries"--were collected from 179 children in Wetaskiwin and 230 children in Camrose. Fluoride values, based on the analyses of Hargreaves, were assigned to the reported consumption of the children with the three highest and three lowest total beverage intakes in each community. A wide range of available fluoride was found. A substantial source of fluoride was shown to be available in the non-fluoridated community from beverages other than water, primarily from carbonated beverages commercially prepared with fluoridated water. Available beverages and actual consumption should be considered in the prescription of fluoride supplementation for children with minimal fluoride in their drinking water.

Caries prevalence and length of residency in fluoridated and non-fluoridated communities.

The caries experience of grade 6 Canadian schoolchildren was examined related to length of residence in non-fluoridated Camrose (0.23 ppm) and adjacent fluoridated Wetaskiwin (1.08 ppm). The mean age was 11.94 +/- 0.65 years, 115 being examined in Camrose and 89 in Wetaskiwin. The mean DMFT and DMFS values were similar in both the non-fluoridated and fluoridated communities with DMFT of 2.39 and 2.65 and DMFS of 3.40 and 3.54, respectively. When a minimum 5-year residency requirement was imposed, the data changed, showing for those children with 5-year residency DMFT values of 2.43 and 2.26 and DMFS values of 3.35 and 2.79, respectively, for non-fluoridated Camrose and fluoridated Wetaskiwin. Although the fluoridated community had 17% less surfaces with caries, differences between the fluoridated and non-fluoridated communities were not statistically significant. Within the fluoridated community, differences in DMFT and DMFS between children resident less than 5 and greater than 5 years were statistically significant (DMFT p less than 0.05; DMFS p less than 0.01). When comparing regions where adjacent communities exist, with and without water fluoridation, and in making decisions on fluoride supplementation levels for children who have changed residency to such communities, it is important that this type of information is taken into account.

The impact of demographic, economic and social trends on oral health care.

Concurrent with the new technologies in oral disease prevention, diagnosis, and treatment are the changing global perspectives on health which impact significantly on who will actually receive the new technologies and services. Issues of access to care, the rapidly changing social, political, and economic environments and the growing recognition of the disparities and barriers to oral health are stimulating new strategies for positive change and enhancement. Governments, in partnership with professional associations, private sector concerns and consumer interests in Canada and the United States, have recently reviewed current oral health status and identified needs and inequities. A few bold new multisectoral initiatives have evolved but not enough to address all the trends. The challenges not adequately addressed by current policies and practices have been identified. Goals for oral health have been established both nationally and internationally to address the trends and the challenges. Critical areas for taking action have been also been identified and include research in epidemiology, behavioural and social sciences, health services, and evaluation. This type of research considers the social and environmental context of where and how oral services are provided. Ultimately this is the kind of research that can radically change the role of the dental hygienist in the delivery of oral health care.
