Previous reports found that some fluoride-containing dentifrices do not release effective concentrations of fluoride during brushing. Failure to release fluoride can be due to dentifrice matrix components that interfere with the solubilization of the fluoride salts during brushing. A new generation of dentifrices has the capability to precipitate beneficial fluoride salts during tooth brushing....

introduction: over twenty developed and developing countries have regions with endemic floursis, on the other hand tooth decay as an infectious disease in human societies is reported to occur due to the shortage of fluoride in water. since decayed, missing, and filled teeth dmft is considered a 52 -character indicator in health equity, the present research aims at studying the relationship betw...

BACKGROUND Because of the potential for contamination of municipal water supplies, people appear to be turning to alternative sources for their pure drinking water. OBJECTIVES The present study analyzed the fluoride concentration in community water and bottled drinking water sold in Faridabad city. METHODS A comparative evaluation of fluoride content in community water supply and bottled dr...

BACKGROUND In India, for the high concentration of fluoride in groundwater, people are at risk of dental fluorosis. The problem is common in various states of India. The condition in Rajasthan is worse where all districts have such a problem. OBJECTIVE To study the fluoride concentration in groundwater and prevalence of dental fluorosis in Didwana block of Nagaur district, Central Rajasthan, ...

The turnover of skeletal fluoride, a process which involves the acquisition and elimination of fluoride by bone, has not been completely studied. This topic is of current interest in relation to the programs of fluoridating communal water supplies as a means of partial control of dental caries in the human (1). Skeletal tissues have a marked affinity for fluoride and the bones are known to accu...

BACKGROUND AND AIMS The aim of the present study was to systematically review fluoride concentration of drinking waters and prevalence of fluorosis in Iran through systematically evaluating results of studies conducted in this regard. MATERIALS AND METHODS In this systematic review study, the required data was collected using keywords including drinking water fluoride, fluoride concentration,...

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...

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 ...

The purpose of this review is to describe various geological and chemical factors that are controlling the fluoride concentration in soil, rocks, water, air, plants, animals and food stuffs. Further to discuss well established method that is used as the standard methods of analysis. Rock, Soil, Water, air, plants, animals, foodstuffs all contain fluoride in widely varied concentration.
