This work was based on the hypothesis that fingernail clippings can be used as a biomarker for the subchronic exposure to fluoride. The results provide data on factors that may affect the concentration of fluoride in fingernail clippings as determined with the electrode following HMDS-facilitated diffusion. The following variables had only minor or no(More)
The aim of this study was to investigate the relationship between nutritional status and dental fluorosis in areas with fluoride in the drinking water in Paraíba, Brazil. Rural villages of comparable low socio-economic status and stable water fluoride levels were selected. Lifelong residents (6-11 years old, n = 650) were examined for nutritional status(More)
The effect of orthodontic treatment on the prevalence of Streptococcus mutans was investigated in 14 subjects. Insertion of appliances tended to give a transient decrease in S.mutans levels, in both plaque and saliva, possibly due to elimination of S.mutans reservoirs by the banding procedure. After 3 months of extensive banding, the S.mutans proportions(More)
The relationship between root caries, oral sugar clearance, salivary flow rate, and salivary counts of mutans streptococci, lactobacilli and candida has been studied in a group of 22 rheumatic patients (age range 40-72 years). The study group comprised all subjects volunteering for a clinical trial on relief of dry mouth symptoms. The median salivary flow(More)
The aim of the present investigation was to study intra-oral variations in total plaque fluoride, and to examine whether such variations were related to plaque pH. Five orthodontic patients abstained from oral hygiene and daily fluoride rinsing for 2 days. Resting and fermenting plaque pH was measured with a touch micro-electrode at 14-21 localized sites on(More)
Salivary mucins can aggregate oral bacteria and also constituents of pellicle and plaque. A,B, and H blood group antigens are present on the mucins of secretors only. These mucins have also been shown to contain more carbohydrate than non-secretor mucins. The aim of the present study was to relate these genetically determined differences in mucin(More)
