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...

BACKGROUND One of the most undesirable side effects of comprehensive orthodontic treatment is white spot lesions (WSLs). Despite many attempts at prevention of WSLs, its prevalence remains very high on debonding. There are many agents like fluoride toothpastes, fluoride varnishes, and fluoride mouth rinses, and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) is frequently used for t...

Abstract Background and purpose Fluoride is one of the fundamental and required components in human body. The current study intends to survey the status of fluoride in drinking water supplies ( underground water source and drinking water) in Qaemshahr city from 2006 (march/21) to 2012(march/19) and comparison with universal standards, national and climatic conditions. Materials and methods This...

In countries with fluoridation of public water, it is imperative to determine other dietary sources of fluoride intake to reduce the public health risk of chronic exposure. New Zealand has one of the highest per capita consumption rates of black tea internationally and is one of the few countries to artificially fluoridate public water; yet no information is available to consumers on the fluori...

We have compared the renal excretion of fluoride in a variety of patients with chronic renal failure maintained with and without protein restriction before and during regular dialysis treatment and after transplantation. The patients tended to continue to excrete normal dietary loads of fluoride quite well until renal function was seriously reduced. From a regression of function on excretion th...

It was the aim of this study to investigate differences in fluoride bioavailability in different oral areas after the application of amine fluoride (AmF) and sodium fluoride (NaF). The null hypothesis suggested no differences in the fluoride bioavailability. The tongue coating was removed and biofilm samples from the palate, oral floor and cheeks were collected. All subjects brushed their teeth...

The adenylate cyclase system in a plasma membrane-rich fraction termed “ghosts” from rat adipocytes is activated by epinephrine, adrenocorticotropic hormone, glucagon, and secretin, and is also stimulated in the presence of fluoride ion. Studies of the temperature dependency of activation by these agents showed that whereas hormonal activation occurs down to lo”, activation by fluoride ion is m...

OBJECTIVE To investigate and compare the amount of fluoride release of conventional, resin modified and nanofilled resin modified glass ionomer cements. MATERIALS AND METHODS Tablets of glass-ionomer cements were immersed in deionized water and incubated at 37°C. After 1, 2, 7, 15 and 30 days, fluoride ion was measured under normal atmospheric conditions by fluoride ion selective electrode. B...

We would like to comment on the paper ‘Total and free fluoride concentrations of African dentifrices marketed in West Africa’ by Jordan et al, published in Oral Health and Preventive Dentistry 2011;9:53–58. At the time of publication of the paper, we observed the shortcomings with regard to the method of fluoride analysis used, but since the problem was obvious to those who are working in this ...
