The in vitro fluoride uptake by dental enamel from two conventional acidulated phosphate fluoride gels was compared to a thixotropic acidulated phosphate fluoride gel. The fluoride concentration and enamel biopsy depths were determined using an acid-etch biopsy method based on calcium determinations. A significant fluoride uptake by dental enamel from a thixotropic topical fluoride agent follow...

AIM The aim of this conference paper was to systematically review the quality of evidence and summarize the findings of clinical trials published after 2002 using fluoride mouth rinses, fluoride gels or foams for the prevention of dental caries. METHODS Relevant papers were selected after an electronic search for literature published in English between 2003 and 2014. The included papers were ...

There have only been few investigations comparing total fluoride intake and the fluoride proportion excreted in urine in pre-school children. In addition, the results of available studies are conflicting. Total fluoride intake was assessed in 11 healthy children aged 3-6 years on 2 consecutive days and urinary fluoride excretion was determined. The duplicate-diet approach was used for the asses...

The take-on population is defined as all patients over 18 who started RRTat UK renal centres and did not have a recovery lasting more than 90 days within 90 days of starting RRT. The treatment timeline is used to define take-on patients as follows. If a patient has timeline entries from more than one centre then these are all combined and sorted by date. Then, the first treatment entry gives th...

Recent trends in the prevalence of dental caries in children, as well as a possible increase in the prevalence of dental fluorosis, have prompted some researchers to suggest the reassessment of water fluoride concentration standards. Instead of reducing water fluoride concentrations, an alternative approach would be to limit the use of, or reduce the fluoride concentration of, dentifrices, mout...

BACKGROUND In this paper, the characteristics of the early stage of dental caries are discussed and the methods we used to treat the early stage of dental caries to increase the number of caries-free patients are presented. Studies from in vitro to in situ experiments and a clinical study were carried out to support clinical remineralization therapy. METHODS AND RESULTS To clarify the effect ...

Fluorosis prevalence has increased in North America since the 1930's-1940's. It may also have increased since 1970, though the evidence for that is less clear. Continued monitoring will help determine whether increased fluorosis prevalence in children in the United States is a cohort effect from the 1970's. This review considers the evidence for an increase in fluoride ingestion from all source...

fluoride in drinking water has a profound effect on teeth. since drinking water is an important source of fluoride, the evaluation of the fluoride content of water resources is necessary. temporal variations and spatial distribution of fluoride in drinking water of some selected parts of kurdistan province, iran, have been studied using geographic information system (gis) techniques. thus, 40 v...
