The objective of this paper was to report on the level of support for water fluoridation among parents of primary school children in Lithgow and on the socio-demographic and oral health factors that may have influenced this support. As part of a survey in Lithgow of the oral health status of school children, their parents were asked to complete an oral health-related questionnaire. Questions on support for fluoridation and socio-demographics were included. Descriptive statistics and logistic regression analysis were used to examine associations between variables. Seventy per cent of the responding parents supported water fluoridation. However, this support was significantly higher among those from a higher socio-economic background. Nearly half the parents thought that health authorities or the government should take on the responsibility for matters related to water fluoridation. No statistically significant differences in caries experience were observed amongst children whether or not their parents supported fluoridation, except for 5-6 year olds (p < 0.01). Lithgow parents strongly supported the introduction of water fluoridation but suggested that governments and health authorities should adopt a more proactive role in relation to fluoridation implementation.

Background: It is important to evaluate concurrently the benefit for dental caries and the risk for dental fluorosis from early exposure to fluoride among children., Aim: To evaluate associations of different levels of exposure to fluoride in early childhood with dental caries and dental fluorosis experience in school children., Methods: A Child Dental Health Survey (CDHS) was conducted among school children in the Australian state of New South Wales (NSW) in 2007. Trained and calibrated examination teams conducted oral epidemiologic examinations to assess caries experience as decayed, missing or filled tooth surfaces of the primary and permanent dentitions (dmfs/DMFS) and fluorosis using the Thylstrup & Fejerskov (TF) index on the maxillary central incisors only. A parental questionnaire collected information on residential histories and tap water usage to enable calculation of percentage of 3-year lifetime exposure to fluoride in water. Use of dietary fluoride supplements was also collected. Dental caries and fluorosis experience were compared among groups by levels of exposure to fluoride from water and fluoride supplements in bivariate and multivariable analysis, controlling for socioeconomic factors., Results: Exposure to different fluoride sources varied in the group of 2611 children aged 8-12 years. Lower household income was significantly associated in both bivariate and multivariable analyses with the greater prevalence and severity of primary tooth caries among 8-10-year-old children and permanent tooth caries among 8-12 year old. Exposure to fluoride in water during the first 3 years of life was associated with both caries and fluorosis experience observed at age 8-12 years. Having higher percentage of 3-year lifetime exposure to fluoride in water was associated with higher prevalence of mostly mild fluorosis, but significantly lower prevalence and severity of caries in the primary and permanent dentitions., Conclusion: There were significant associations of dental caries and fluorosis experience with sources of early childhood fluoride exposure among children aged 8-12 years in New South Wales. Exposure to fluoridated water during the first 3 years of life was associated with better oral health of school-age children., (© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

The State of New South Wales (NSW) in Australia has over half a century of experience with water fluoridation. Yass was the first town to be fluoridated in 1956 and Sydney in 1968, and by the late 1970s, approximately 90% of NSW was fluoridated. However, since then, there have been no new fluoridation schemes. In NSW under the Fluoridation of Public Water Supplies Act 1957, the decision to fluoridate rests with local government authorities (councils). Since 2004, the NSW Health Department has been proactive in promoting and extending water fluoridation to unfluoridated rural communities in an attempt to reduce oral health inequalities. This has resulted in 20 councils implementing fluoridation, increasing population coverage of water fluoridation from 90% in 2004 to 96% in 2012. When the remaining 16 councils that have been gazetted to fluoridate implement fluoridation, approximately 98% of NSW residents will have access to fluoridated water. This article provides an overview of the framework used to extend water fluoridation to many rural communities in New South Wales in the 21st century., (© 2012 John Wiley & Sons A/S.)

Background: Data regarding the long-term effects of smoking, smoking cessation and environmental tobacco smoke (ETS) on tooth loss are limited., Methods: The authors collected information about tooth loss and other health-related characteristics from a questionnaire administered to 103,042 participants in the 45 and Up Study conducted in New South Wales, Australia. The authors used logistic regression analyses to determine associations of cigarette smoking history and ETS with edentulism, and they adjusted for age, sex, income and education., Results: Current and former smokers had significantly higher odds of experiencing edentulism compared with never smokers (prevalence odds ratio [OR], 2.51; 95 percent confidence interval [CI], 2.31-2.73 and OR, 1.50; 95 percent CI, 1.43-1.58, respectively). Among former smokers, the risk declined significantly with increasing time since smoking cessation; however, the risk remained elevated even in those who ceased smoking 30 or more years previously compared with that in never smokers (OR, 1.10; 95 percent CI, 1.02-1.19). Furthermore, among never smokers, the OR for edentulism was 1.37 (95 percent CI, 1.17-1.60) in those who reported having exposure to ETS for six or more hours per week versus those who were not exposed to any ETS., Conclusions: and, Clinical Implications: Although the risk of experiencing tooth loss declines with time since smoking cessation, the effects of smoking may persist for at least 30 years. The effect of ETS requires further investigation.

Objectives: This article describes the strategies adopted to influence the outcome of a plebiscite held in March 2004 in favor of water fluoridation in Deniliquin, a rural town in New South Wales, Australia., Methods: The health promotion strategies undertaken included the following: a) the skillful use of media to educate the community on the benefits of water fluoridation; b) disseminating contemporary local data to demonstrate oral health disparities with neighboring fluoridated townships; and c) a well-established lobbying machine to mobilize the community., Results: Out of a total population of 5,280 on the electoral roll, 4,539 residents voted, giving a response rate of 86 percent. The wording of the plebiscite was "Do you support the addition of fluoride to Deniliquin town water supply?" There were 2,533 "yes" votes (55.8 percent), 1,879 "no" votes (41.4 percent), and 127 spoiled votes (2.8 percent)., Conclusions: The council resolved to implement water fluoridation and the residents received fluoridated water in January 2005.

Objectives: The 2004-06 National Survey of Adult Oral Health was Australia's second oral examination survey of a nationally representative sample of adults. The aim of this paper is to provide a brief overview of oral health in the NSW adult population from the findings of the survey., Methods: A three-stage, stratified, clustered sampling design was used to select NSW residents aged 15 years and over. Self-reported information about oral health was obtained through telephone interviews. People with natural teeth were offered clinical examinations., Results: 3630 people were interviewed and 1099 underwent a clinical examination. Only 5.5% of the study population were edentulous (all natural teeth missing) compared with the national estimate of 6.4%. The Decayed, Missing, Filled Teeth (DMFT) caries severity index was 12.8, equal to that of the Australian population; prevalence of untreated decay was 27.1%, which was not significantly different to the national estimate of 25.5%. Some 60.3% of the NSW survey sample had visited a dentist within the last 12 months (nationally 59.4%) and 56.8% visited for a check-up (56.2% nationally). Oral health, use of dental services and perceptions of need varied significantly by geographic location, private insurance patronage and eligibility for public dental care., Conclusions: The oral health of the NSW adult population and patterns of dental care are similar to that estimated nationally. The prevalence and severity of dental diseases and oral health behaviours are influenced by social and geographic factors.

Objective: To determine cost of dental services provided to a cohort of insured population 18 years and over, who used private general dental practice in New South Wales, Australia., Basic Research Design: This cohort study used the person-years method and Weibull regression for analysis. Setting Data were derived from claims records submitted for rebates by members of a health insurance fund for services they received in private general dental practice during 1 January 1992-31 December 1995., Participants: 75,501 members from New South Wales., Main Outcome Measures: To determine, by age groups, the cost per item of dental service, cost of services received at a visit and cost of services received per year., Results: The median cost per item of dental service received for all ages was A$36.7; with cost increasing with age until 55-64 year age group where an apparent plateau occurred. The median cost of services received at a visit for all ages was Australian dollars 93.5. Cost of services received at a visit increased with age, reaching a plateau in the middle aged groups. The median cost of providing services for all age groups per year was Australian dollar 183.6. The cost of services per year when compared with the youngest age group (18-24 years) increased by about 20% for each successive age group up to the 45-54 year age group. From 55 years onwards the cost levelled off at approximately 70% more than the youngest age group., Conclusion: The cost of providing dental services increased with age to reach a plateau in the middle age groups.

This paper presents some information, derived by questionnaire, on the social characteristics and background of 1148 first-year dental students at the University of Sydney for the years 1976-1985. Student entry age was 19.4 years; 27 per cent were female; 36 per cent of fathers and 24 per cent of mothers were professionals and 37 per cent of fathers and 11 per cent of mothers had attended university; parents of female students had higher educational levels than parents of male students; 55 per cent had medicine as the course of first preference. Eighty-five per cent of students entered dentistry from high school with 78 per cent from Sydney. Characteristics of students showed little change over the period 1976-1985. Some changes noted were an increase in the number of female students with fewer living in their parents' home; increase in number of students from government schools; decrease in foreign students but an increase in students (Australian citizens, or residents) born overseas, and of different ethnic backgrounds.
