This study aimed to investigate root caries prevalence in areas with and without water fluoridation at the Southeast region of São Paulo State, in the adult population, employees of public and private schools, and elderly population. Epidemiological surveys were conducted according to the World Health Organization guidelines (1997), including 1,475 dentate individuals aged 35 to 44 years and 65...

It may be difficult for small and medium cities to obtain information about the fluoride content of public water, because of the lack of equipments and technicians. This study aimed to analyze the fluoride levels of the water supplied by the public treatment stations of 40 cities situated in the northwest region of São Paulo State, during a period of 6 months, to verify if fluoridation occurs i...

OBJECTIVES Claims have been made that the effectiveness of water fluoridation has reduced due to the widespread availability of other sources of fluoride. This study examines the differences in the oral health of children living in fluoridated and non-fluoridated areas of Canterbury and Wellington, New Zealand. DESIGN The data used in this cross-sectional study had been routinely collected in...

Residual stress and lattice defects in commercial zinc anodes are essential factors for dendrite formation during deposition as they lead to a heterogeneous limit the epitaxial growth of zinc. In their Research Article (e202218612), Haiyan Wang et al. propose an annealing strategy defect repair residual relief. As result, reconstructed anode achieved highly growth. Heritage Science Fluoridation...

In this article, we summarise research that identifies best practice for communicating about hazards where the risk is low but public concern is high. We apply Peter Sandman's 'risk = hazard + outrage' formulation to these risks, and review factors associated with the amplification of risk signals. We discuss the structures that determine the success of risk communication strategies, such as th...

The proposed plan consists of three parts: (1) a programme for the promotion of community water fluoridation and other approved methods for the prevention of dental caries; (2) a plan for coordinated study and research into the etiology and prevention of dental caries and related problems; and (3) a plan for an information gathering and dissemination system which is expected to link the prevent...

Disczusion and conclusions In the official report on the studies (Ministry of Health, Scottish Office, Ministry of Housing and Local Government, 1962) comparison is made between the findings in Great Britain and those in the Grand Rapids study in the United States (Arnold, Dean, Jay & Knutson 1956). After adjustment for changes in the control areas, the reduction among children aged 4 years was...
