1. Association Between Saliva Quantity and Content Parameters with Caries Intensity Levels: A Cross-Sectional Study Among Subcarpathian Children
Abstract Objective: To evaluate saliva quantity and content parameters among children of 7 and 12 years old, who permanently living on the territory of Subcarpathia with the registered territory-associated fluoride deficiency in the water, and their association with the caries status of pediatric patients. Material and Methods: The study sample was formed

2. Application of Taguchi Method to Study Morphological Evolution of TiO2 Nanotubes Obtained Via Anodization Process
The growth of titanium dioxide nanotubes (TiO2) via anodization process depends on the controlling parameters such as applied potential, anodization time, and electrolyte composition. In the present work, the Taguchi method was applied to evaluate statistically the influence of the anodization parameters on the morphology of anodized TiO2 films. Mixture of e

3. Effect of fluoride on salivary immunoglobulins and sialic acid
Summary Objective: The aim of our study was to evaluate the effect of fluoride on salivary immunoglobulin and sialic acid levels in children with dental fluorosis and healthy teeth who live in places with high fluoride concentration in drinking water. Method: Fifty-one (51) healthy children between 6 and 12 years old with no caries were randomly selected f

4. Liver proteome of mice with different genetic susceptibilities to the effects of fluoride
ABSTRACT A/J and 129P3/J mice strains have been widely studied over the last few years because they respond quite differently to fluoride (F) exposure. 129P3/J mice are remarkably resistant to the development of dental fluorosis, despite excreting less F in urine and having higher circulating F levels. These two strains also present different characteristics

5. ADSORPTION OF MANGANESE FROM ACID MINE DRAINAGE EFFLUENTS USING BONE CHAR: CONTINUOUS FIXED BED COLUMN AND BATCH DESORPTION STUDIES
AbstractIn the present study, continuous fixed bed column runs were carried out in an attempt to evaluate the feasibility of using bone char for the removal of manganese from acid mine drainage (AMD). Tests using a laboratory solution of pure manganese at typical concentration levels were also performed for comparison purposes. The following operating variab

6. Dental fluorosis and its influence on children’s life
This study verified the prevalence of dental fluorosis in 12-year-old children and its association with different fluoride levels in the public water supply, and evaluated the level of perception of dental fluorosis by the studied children. To assess fluorosis prevalence, clinical examinations were performed and a structured instrument was used to evaluate t

7. Water fluoridation in 40 Brazilian cities: 7 year analysis
Objectives Fluoride levels in the public water supplies of 40 Brazilian cities were analyzed and classified on the basis of risk/benefit balance. Material and Methods Samples were collected monthly over a seven-year period from three sites for each water supply source. The samples were analyzed in duplicate in the laboratory of the Center for Research in P

8. Seven years of external control of fluoride levels in the public water supply in Bauru, São Paulo, Brazil
Fluoridation of the public water supplies is recognized as among the top ten public health achievements of the twentieth century. However, the positive aspects of this measure depend on the maintenance of fluoride concentrations within adequate levels. Objective To report the results of seven years of external control of the fluoride (F) concentrations in t

9. Efeito do fluoreto no osso de camundongos com diferentes susceptibilidades genéticas à fluorose: uma análise proteômica / Effect of fluoride on bone of mice with different genetic susceptibilities to fluorosis: a proteomic analysis
Genetic factors have been shown to influence bone and enamel responses to fluoride (F), but the molecular mechanisms involved remain unclear. In this study, a label-free proteomics approach was employed to identify and evaluate changes in bone protein expression of two mouse strains with different susceptibilities to fluorosis (A/J a susceptible strain, 129P

10. External control of the public water supply in 29 Brazilian cities
The fluoridation of public water supplies is considered the most efficient public health measure for dental caries prevention. However, fluoride levels in the public water supply must be kept constant and adequate for the population to gain preventive benefit. The aim of this study was to analyze fluoride levels in the public water supply of 29 Brazilian mun

11. Efeito do fluor sobre a matriz organica do esmalte dentario de camundongos / Fluoride effect in the secretory-stage enamel organic extracellular matrix of mice
Dental fluorosis is characterized by alterations in the aspect of mature enamel due to hypomineralization, it is caused by chronic ingestion of fluoride during tooth development. Fluoride seems to influence on formation of enamel organic matrix. Previous studies have shown that the organic extracellular matrix of the enamel secretory phase is birefringent, e

12. Prevalence of enamel white spots and risk factors in children up to 36 months old
The aim of this study was to determine the prevalence of enamel white spots and the quality of oral hygiene in children up to 36 months old, in municipalities with different fluoride levels in the water supply, analyzing the contribution of several variables. After approval of the Ethics Committee, the parents signed an informed consent form and were intervi
