13. Enamel crystals of mice susceptible or resistant to dental fluorosis: an AFM study
Objective: This study aimed to assess the overall apatite crystals profile in the enamel matrix of mice susceptible (A/J strain) or resistant (129P3/J strain) to dental fluorosis through analyses by atomic force microscopy (AFM). Material and Methods: Samples from the enamel matrix in the early stages of secretion and maturation were obtained from the inc

14. Factors associated with dental fluorosis in school children in southern Brazil: a cross-sectional study
This cross-sectional study assessed risk factors for dental fluorosis (DF) among 8- to 12-year-old children in southern Brazil. Children attending 20 schools were randomly selected (n = 1,196). They were interviewed and their parents answered a questionnaire that was sent home. Prevalence of DF was 8.53% (modified Dean’s criteria), and the prevalence of se

15. Evidence-based recommendation on toothpaste use
Toothpaste can be used as a vehicle for substances to improve the oral health of individuals and populations. Therefore, it should be recommended based on the best scientific evidence available, and not on the opinion of authorities or specialists. Fluoride is the most important therapeutic substance used in toothpastes, adding to the effect of mechanical to

16. Agreement between parents and adolescents on dental fluorosis: a population-based study
This study evaluated the prevalence and severity of dental fluorosis and compared the reports from adolescents aged 12 to 18 years with those of their parents regarding the perceptions and concerns arising from this disease. The study was conducted in the cities of Viçosa and Sobral and the District of Rafael Arruda (Sobral), Ceará. A cross-sectional study

17. 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

18. 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

19. Efeito do dentifrício fluoretado na incidência de cárie na dentição decídua e fluorose na dentição permanente: revisões sistemáticas e metanálises / Effect on the incidence of caries in the primary dentition and fluorosis in the permanent dentition of fluoride toothpaste:systematic reviews and meta-analyses
Apesar do potencial anticárie do dentifrício fluoretado na dentição permanente estar bem estabelecido, existe uma lacuna no conhecimento em relação ao seu efeito na dentição decídua; não existe consenso quanto à concentração ideal de fluoreto no dentifrício capaz de maximizar o benefício anticárie na dentição decídua e simultaneamente mini

20. Efeito do ph e da concentração de flúor presente em dentifrícios líquidos no controle de cárie em área não fluoretada: estudo clpinico randomizado.
The aim of this randomized clinical trial was to evaluate the effect of pH and fluoride concentration in liquid dentifrices in the control of dental caries in early childhood, in non-fluoridated area. In addition, this study evaluated the influence of pH and fluoride concentration in toenails and in the fluoride uptake in plaque. The sample comprised 212 chi

21. 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

23. Clinical status of permanent first molars in children aged seven to ten years in a Brazilian rural community
AIM: To evaluate the clinical status of permanent first molars and associations with dental caries, gingival bleeding, dental fluorosis and malocclusion. METHODS: An observational study was carried out in a rural community denominated Morro do Saboó in the city of São Roque, state of São Paulo, Brazil. A total of 194 children aged seven to ten years were

24. Sodium fluoride does not alter sperm production or sperm morphology in rats
The aim of the present study was to evaluate the effects of sodium fluoride (NaF) on the male reproductive system. Adult male rats were exposed to NaF in drinking water for 30 days at three concentrations: 1.54 (control, tap water), 50 and 100 ppm. Body and organ weights, daily sperm production, sperm number and morphology were investigated. No difference wa
