Dental caries is the most common oral disease seen in children and adolescents. This study was conducted to assess prevalence of dental caries at different water fluoride levels in Nalgonda district of Andhra Pradesh. A total of 1800 school children aged 12-15 years were selected by stratified cluster sampling from three areas with different levels of natural fluoride concentrations in drinking...

BACKGROUND & OBJECTIVES Endemic fluorosis resulting from high fluoride concentration in groundwater is a major public health problem in India. This study was carried out to measure and compare the prevalence of dental fluorosis and dental caries in the population residing in high and normal level of fluoride in their drinking water in Vadodara district, Gujarat, India. METHODS A cross-section...

in order to determine the genetics of barley lines for freezing resistance based on crown survival percentage an experiment was carried out as a split plot design on the basis of randomized complete blocks with two replications. forty barley lines were assigned in subplots and five freezing temperatures (-8, -11, -13, -15 and -17 ˚с) were allocated in main plots. the results showed significant ...

The impact of dental fluorosis in children exposed to fluoride in drinking water and dentifrice was evaluated. Dental fluorosis was found in 72% of the children, but the children's well-being was not affected. It was concluded that although dental fluorosis due to the intake of optimally fluoridated drinking water and dentifrice did not affect the dental aesthetics of this studied population sa...

BACKGROUND In this study morphological and molecular characterization of Acanthamoeba strains, isolated from dental unit waterlines (DUWLs) were surveyed and the levels of disinfection achievable in vitro by the application of ozone disinfectant to DUWLs were evaluate. METHODS Water samples were collected from air-water syringes, cup fillers and tap water before and at the end of the working ...

Effective infection control is one of the cornerstones of good practice and clinical governance. Due to a combination of negative publicity and an increased scientific knowledge of dental unit waterlines’ (DUWL) biofilms and their associated risks, contamination of dental unit waterl ines has become a prominent infection-control issue. The perceived threat to public health from DUWL contaminati...

An autoclavable air turbine handpiece, Air Flushing Clean System (AFCS) (Osada Electric Co., Ltd., Tokyo, Japan) was developed for use in dentistry with the objective of reducing cross-contamination. Its potential for bacterial contamination was investigated in vitro using two bacterial strains (Streptococcus mutants ATCC 25175 and Staphylococcus aureus FDA 209 P). In theory, this device should...

The aim of this research was to explore and synthesise learning from stakeholders (NHS dentists, commissioners and patients) approximately five years on from the introduction of a new NHS dental contract in England. The case study involved a purposive sample of stakeholders associated with a former NHS Primary Care Trust (PCT) in the north of England. Semi-structured interviews were conducted w...
