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 ...

OBJECTIVES The aim of this study was to determine the fluoride levels in breast milk and plasma of lactating mothers who regularly consumed drinking water with low levels of fluoride. METHODS One hundred twenty five healthy mothers aged between 20-30 years old who had given birth within 5-7 days were included in the study. Besides being otherwise healthy, the primary selection criteria stipul...
