Background & aims: To identify manufactured soy-based products more recommended by pediatricians and nutritionists; to determine fluoride concentrations in these products; to evaluate children concerning fluorosis in primary teeth and its association with the consumption of soy-based products. Methods: Pediatricians and Nutritionists answered a questionnaire about soy-based products they most recommended to children. Fluoride concentrations of the 10 products more cited were analyzed with the ion-specific electrode. Dental fluorosis exams were performed in 315 4e6-year-old children. Dean’s Index was used to assess fluorosis. Among the children examined, 26 had lactose intolerance. Their parents answered a questionnaire about children’s and family’s profile, besides permitting the identification of soy-based products use. Chi-squared and Multivariable Logistic Regression tests were used (p < 0.05). Results: Fluoride content in the analyzed products ranged from 0.03 to 0.50 mg F /mL. Dental fluorosis was detected in 11% of the children, with very mild and mild degrees. Dental fluorosis in primary teeth was associated with lactose intolerance (p < 0.05), but there was no significant association with the use of manufactured soy-based products. Conclusions: Isolated consumption of soy-based products recommended by health professionals to children do not offer risk of dental fluorosis in primary teeth...

A fluorose dentária é uma patologia que ocorre durante a formação dos dentes na presença de doses excessivas de fluoreto (F-). Os mecanismos pelos quais o F provoca a fluorose ainda são poucos conhecidos. A influência de fatores genéticos tem sido considerada na suscetibilidade/resistência do indivíduo em desenvolver a fluorose. Duas linhagens de camundongos (A/J e 129P3/J) com diferença na resistência ou suscetibilidade à fluorose dentária foram utilizadas para determinar se a suscetibilidade à fluorose pode ser explicada pela diferença no metabolismo e se há diferença no perfil protéico dos rins e urina destes animais. Para isso, um estudo metabólico foi conduzido com 18 camundongos A/J (suscetível) e 18 129P3 / J (resistente) após o desmame. Cada amostra foi dividida em 3 grupos, com diferentes concentrações de F- na água de beber (0, 10 e 50 ppm F). Uma vez que um estudo piloto revelou que os camundongos A/J ingeriam um maior volume de água quando comparado com o 129P3/J, a concentração de F- na água dada aos camundongos A/J foi ajustada semanalmente a fim de fornecer doses semelhantes de F- para ambas linhagens. Os animais foram mantidos em gaiolas metabólicas (n = 2/gaiola) por 7 semanas, com livre acesso à água e dieta de baixa ingestão de F- (0...

Apesar da grande utilização de alimentos industrializados à base de soja, não há relatos científicos conclusivos que demonstrem a possível influência do flúor contido nesses alimentos sobre a ocorrência de fluorose em dentes decíduos. São inúmeras as indicações desses alimentos, em especial nos casos de intolerância à lactose. Os objetivos deste estudo foram: 1) Identificar os alimentos industrializados à base de soja mais recomendados, por nutricionistas e médicos pediatras, para crianças; 2) Determinar as concentrações de flúor nesses alimentos; 3) Avaliar crianças com idade entre 4 a 6 anos quanto à prevalência de fluorose, na dentição decídua. Etapa 1. A amostra foi constituída por 20 médicos pediatras e 20 nutricionistas de Bauru-SP, que responderam um questionário dirigido, composto de questões objetivo-descritivas, sobre os alimentos à base de soja que eles mais indicam para crianças. Etapa 2. Foram relacionados os 10 alimentos mais citados, sendo analisadas as concentrações de flúor das amostras com eletrodo íon-específico (Orion 9409), após difusão facilitada por HMDS. Etapa 3. Foi realizado o levantamento epidemiológico de fluorose dentária em 6 escolas de Bauru-SP. Participaram 315 crianças com idade entre 4 e 6 anos...

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutritional factors and bone growth. The risk period for esthetic changes in permanent teeth is between 20 and 30 months of age. The recommended level for daily fluoride intake is 0.05 - 0.07 mg F/Kg/day, which is considered of great help in preventing dental caries, acting in remineralization. A daily intake above this safe level leads to an increased risk of dental fluorosis. Currently recommended procedures for diagnosis of fluorosis should discriminate between symmetrical and asymmetrical and/or discrete patterns of opaque defects. Fluorosis can be prevented by having an adequate knowledge of the fluoride sources, knowing how to manage this issue and therefore, avoid overexposure.

Este estudo objetivou estimar a prevalência e severidade da cárie e fluorose dentária aos 12 anos de idade na cidade de Piracicaba/SP e relacionar os dados encontrados com fatores sociais e comportamentais. Foi realizada amostragem probabilística aleatória simples para a seleção das escolas púbicas e dos voluntários. A amostra constituiu de 1104 escolares, provenientes de 21 escolas, que foram examinados de acordo com a metodologia proposta pela OMS (1997), por dois examinadores previamente treinados e calibrados. No presente estudo, foram analisadas as variáveis dependentes (CPO-D e Fluorose) e as variáveis independentes (Socioeconômicas e Comportamentais). A média do Índice CPO-D encontrada foi de 0,7 e a prevalência de cárie foi de 31,5%. O número total de dentes examinados foi de 27949 dos quais 97,22% (n=27173) estavam hígidos, 0,68% (n=190) estavam cariados, 0,06% (n=16) foram perdidos e 2,04% (n=570) estavam obturados revelando que apenas 2,7% do total de dentes examinados apresentou experiência de cárie (CPO-D>0). Somente 7,5% das crianças apresentou Fluorose dentária (T-F?1), valores considerados muito baixos segundo classificação da OMS. Considerando-se a série histórica desde 1973 quando se iniciou a fluoretação da água de abastecimento público em Piracicaba/SP até o ano de 2013...

The current article proposes a reflection on several aspect pertaining to dental fluorosis in Brazil, based on a systematic review of epidemiological surveys. The authors assess the prevalence and degrees of severity found in different studies and show that in methodological terms, there is a need for progress in procedures for population-based studies on fluorosis. Despite the different data collection approaches, there is some consensus among the different studies as to the limited severity of fluorosis in Brazil, as well as its association with the independent variables age and socioeconomic status. The authors also highlight the importance of adding subjective aspects to the normative diagnosis as a contribution to public health policy decisions, since the use of exclusively clinical criteria gives dental fluorosis more space than society ascribes to it. There is a lack of empirical evidence to reassess the fluoride content in public water supplies, a method that is known to be necessary to improve dental caries epidemiological indicators.

It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) after toothbrushing. The study included 511 individuals aged 7 - 22 years, categorized according to age: 7 - 9 years (n = 227), 10 to 12 years (n = 153), 13 to 15 years (n = 92), 16 to 22 years (n = 39). For the diagnosis of dental caries used the criteria of the World Health Organization to measure indices DMFT. For fluorosis used the index Thylstrup and Fejerskov (TF), dichotomized according to prevalence (TF = 0 and TF > 0) and severity (TF < 4 and TF > 5). In the two younger groups, the DMFT and its decay component were higher in the group with more severe fluorosis (p < 0.001). This association was not found among adolescents and adults (p > 0.05). The association was found between the conditions more severe fluorosis and caries in individuals under 12 years.

OBJECTIVES: The purpose of this study was to determine the prevalence and severity of dental fluorosis among patients attending basic health units in Londrina. METHODS: Five basic health units of the urban area were randomly selected and 434 children attending these units, born between 1986 and 1989 (9 to 12 years of age), were examined. Diagnosis of dental fluorosis was performed by means of the Thylstrup and Fejerskov (TF) Index. Oral examinations were carried out by 5 previously trained dentists with the patients lying in the dental chair, under artificial light, preceded by prophylaxis, isolation with cotton rolls and air-drying of the teeth. Ten percent of the sample was reexamined and an almost perfect agreement on diagnostic criteria was obtained either on the intra-examiner or inter-examiner evaluation (K=1.00, p<0.0001). RESULTS: The observed prevalence of dental fluorosis was 91.0%, and 87.8% of the individuals were classified as TF grade 2 or less. CONCLUSIONS: Despite of the low severity, the high prevalence observed shows the need for regular screening of dental fluorosis in Londrina; establishment of procedures to prevent the overutilization of fluoride both by the professionals and the population; sanitary surveillance of fluoride levels in water supply and also in all sources of fluoride available; besides the need for further studies to understand the factors associated to dental fluorosis among children living in Londrina.

Information on social inequities in health is valuable when allocating resources for public services and formulating health strategies. Research is needed to deepen the understanding of the determinants that lead to inequities in oral health. This cross-sectional study aimed to analyze the association between individual and contextual factors and the prevalence of adverse periodontal condition, malocclusion and dental fluorosis among Brazilian 12- year-old schoolchildren. This study included data from an oral health survey carried out in 2010 in the city of Goiania, Brazil (n = 2,075) and secondary data obtained from the files of the local health authority. Data were collected through oral clinical examinations. For assessment of periodontal status two components of the Community Periodontal Index (CPI) were used: calculus and bleeding after probing. The Dental Aesthetic Index (DAI) was used to assess occlusion and the Dean Index to assess fluorosis. Dependent variables were presence of any periodontal condition, presence of malocclusion (DAI>25) and presence of fluorosis, analyzed separately. Independent individual variables were the children’s sex and color/race, and their mother’s level of schooling. Contextual variables were related to the schools (type and existence of toothbrushing program) and its geographic location in the health districts. Rao-Scott tests were performed for each of the three outcomes and multilevel analysis was performed for periodontal condition (Poisson regression) and malocclusion (Logistic regression). The results are presented in three original articles. The prevalence of calculus and/or bleeding was 7% and higher (P<0.05) in brown pupils...

OBJECTIVE: The objective of this study was to evaluate associations between patterns of infant formula feeding and dental fluorosis and caries in a representative sample of Australian children. METHODS: A population-based study gathered information on fluoride exposure in early childhood. Information on infant formula feeding and fluoridation status was used to group children: three groups in nonfluoridated areas (formula nonuser, user for 6 months, and user for 6+ months) and four groups in fluoridated areas (nonuser, user with nonfluoridated water, user with fluoridated water for _6 months, and user with fluoridated water for 6+ months). Children aged 8-13 years were examined for fluorosis using the Thylstrup and Fejerskov (TF) Index. Primary tooth caries experience recorded at age 8-9 years was extracted fromclinical records. Fluorosis cases were defined as having TF 1+ on maxillary incisors. Fluorosis prevalence and primary caries experience were compared across formula user groups in multivariable regressionmodels adjusting for other factors. RESULTS: Total sample was 588 children. Children in fluoridated areas had higher prevalence of very mild to mild fluorosis, but lower caries experience than those in nonfluoridated areas.Among children in nonfluoridated areas...

The aim of this study was to validate the use of fingernail fluoride concentrations at ages 2-7 years as predictors of the risk for developing dental fluorosis in the permanent dentition. Fifty-six children of both genders (10-15 years of age) had their incisors and premolars examined for dental fluorosis using the Thylstrup-Fejerskov index. Fingernail fluoride concentrations were obtained from previous studies when children were 2-7 years of age. Data were analyzed by unpaired t test, ANOVA, and Fisher's exact test when the fingernail fluoride concentrations were dichotomized (<= 2 or > 2 mu g/g). Children with dental fluorosis had significantly higher fingernail fluoride concentrations than those without the condition, and the concentrations tended to increase with the severity of fluorosis (r(2) = 0.47, p < 0.0001). Using a fingernail fluoride concentration of 2 mu g/g at ages 2-7 years as a threshold, this biomarker had high sensitivity (0.84) and moderate specificity (0.53) as a predictor for dental fluorosis. The high positive predictive value indicates that fingernail fluoride concentrations should be useful in public health research, since it has the potential to identify around 80% of children at risk of developing dental fluorosis.

The aim of this study was to determine the prevalence and severity of dental fluorosis among 12-15-year-old students from João Pessoa, PB, Brazil before starting a program of artificial fluoridation of drinking water. The use of fluoridated dentifrice was also surveyed. A sample of 1,402 students was randomly selected. However, 31 students refused to participate and 257 were not permanent residents in João Pessoa, thus leaving a final sample of 1,114 students. Clinical exams were carried out by two calibrated dentists (Kappa = 0.78) under natural indirect light. Upper and lower front teeth were cleaned with gauze and dried, and then examined using the TF index for fluorosis. A questionnaire on dentifrice ingestion and oral hygiene habits was applied to the students. The results revealed that fluorosis prevalence in this age group was higher than expected (29.2%). Most fluorosis cases were TF = 1 (66.8%), and the most severe cases were TF = 4 (2.2%). The majority of the students reported that they had been using fluoridated dentifrices since childhood; 95% of the participants preferred brands with a 1,500 ppm F concentration, and 40% remembered that they usually ingested or still ingest dentifrice during brushing. It was concluded that dental fluorosis prevalence among students in João Pessoa is higher than expected for an area with non-fluoridated water. However...

INTRODUCTION: Dental fluorosis is a disturbance of high prevalence caused by the ingestion of fluoride ions present mainly in toothpaste. Preventive measures to avoid it are still controversial. Thus, knowing the impact that fluorosis can cause on the population's quality of life it is important for planning public health policies. OBJECTIVE: To evaluate the impact of dental fluorosis on the quality of life of children and adolescents. MATERIAL AND METHOD: We studied 300 subjects aged 8 to 12 years divided into 4 groups: children (8-10 years) and adolescents (10 to 12 years) with and without fluorosis. The diagnosis of fluorosis was performed according to the index Thylstrup and Fejerskov and quality of life was evaluated using Child Perceptions Questionnaire 8-10 and 11-14. The socio-demographic characteristics of the patients were also evaluated. For inclusion in the sample, selected patients should present eight permanent incisors with crowns fully erupted. Patients who had extensive restorations, fractured teeth, other dental enamel defects and who wore braces were excluded. RESULT: Fluorosis was present in 64.7% of the patients analyzed and in most cases (80.3%) was mild or very mild. In children, the average overall score of the questionnaire was 15.9 for the group without fluorosis and 18.3 for the group with fluorosis (p = 0.255). The teenagers' score in the group without fluorosis was 26.1...

INTRODUCTION: Over the last two decades, the prevalence of dental caries in children has decreased and the prevalence of dental fluorosis has increased. Knowledge on the epidemiologic conditions of a population is fundamental for the planning of health programs. OBJECTIVES: To determine the prevalence of dental caries and dental fluorosis among schoolchildren, in Catalão, Goiás, Brazil. METHODS: A random sample of 432 schoolchildren aged 7-12-years old was obtained. WHO (1997) criteria for dental caries and fluorosis diagnosis were used. RESULTS: The DMFT indexes were 0.97; 1.20; 1.80; 1.62; 2.40 and 2.51 for 7, 8, 9, 10, 11 and 12 years old, respectively. Analysis of dental fluorosis for the same ages presented higher prevalence at 12 years old and for the female gender. The percentage of questionable dental fluorosis (Dean's classification) was 34.0%. Only 3% of the sample presented dental fluorosis with scores very mild, mild and moderate. CONCLUSIONS: The prevalence of caries in schoolchildren of Catalão, Goiás, Brazil, was low. In average, private schools showed better results than public schools; however, all schools presented a low DMFT index. In this study, dental fluorosis is not a public health problem and has not damaged dental esthetics.

The aim of this study was to assess agreement in the diagnosis of dental fluorosis performed by a standardized digital photographic method and a clinical examination (gold standard). 49 children (aged 7-9 years) were clinically evaluated by a trained examiner for the assessment of dental fluorosis. Central incisors were evaluated for the presence or absence of dental fluorosis and were photographed with a digital camera. Photographs were presented to three pediatric dentists, who examined the images. Data were analyzed using Cohen's kappa and validity values. Agreement in the diagnosis performed by the photographic method and clinical examination was good (0.67) and accuracy was 83.7%. The prevalence of dental fluorosis was reported to be higher in the clinical examination (49%) compared with the photographic method (36.7%). The photographic method presented higher specificity (96%) than sensitivity (70.8%), a positive predictive value (PPV) of 94.4% and a negative predictive value (NPV) of 77.4%. The diagnosis of dental fluorosis performed using the photographic method presented high specificity and PPV, which indicates that the method is reproducible and reliable for recording dental fluorosis.

Several communities in Paraíba have moderate or high levels of fluoride naturally present in the drinking water. A moderate prevalence of dental fluorosis (30-40%) has been observed in some areas where the levels of fluoride are regarded as "optimal" for the region (0.6 ppm). The aim of the present study was to determine the prevalence of dental fluorosis in Princesa Isabel, a city with "sub-optimal" fluoride levels (0.4 ppm). The sample comprised 142 schoolchildren (10- to 15-year-old subjects) randomly selected and examined by means of the TF (Thylstrup & Fejerskov) index. The clinical exams were carried out under indirect natural light by three calibrated examiners. Prior to the examination the teeth were cleaned and dried. Approximately 20% of the subjects examined presented with some degree of fluorosis. Seventy per cent were classified as TF 1 while 30% were classified as TF 2 to 5. The prevalence of fluorosis was higher in male subjects and in premolars. Although the observed prevalence of dental fluorosis was within the expected levels, other sources of systemic fluoride must be controlled. The observed prevalence of dental fluorosis is not a public health problem in this community.; Diversas localidades da Paraíba possuem níveis moderados ou elevados de fluoreto in natura nas águas de abastecimento. Nas áreas onde os níveis de fluoretos são considerados "ótimos" para a região (0...

It is observational, analytical and cross-sectional aimed to evaluate the association between severity and prevalence of fluorosis and dental caries in rural communities with endemic dental fluorosis in the north state of Minas Gerais, Brazil, with fluoride concentrations in water up to 4.8 mg/L. Data were collected by one examiner (intra-examiner kappa, 0.96 to 0,95 for caries and fluorosis) after toothbrushing. The study included 511 individuals aged 7 - 22 years, categorized according to age: 7 - 9 years (n = 227), 10 to 12 years (n = 153), 13 to 15 years (n = 92), 16 to 22 years (n = 39). For the diagnosis of dental caries used the criteria of the World Health Organization to measure indices DMFT. For fluorosis used the index Thylstrup and Fejerskov (TF), dichotomized according to prevalence (TF = 0 and TF > 0) and severity (TF < 4 and TF > 5). In the two younger groups, the DMFT and its decay component were higher in the group with more severe fluorosis (p < 0.001). This association was not found among adolescents and adults (p > 0.05). The association was found between the conditions more severe fluorosis and caries in individuals under 12 years.

The aim of this study was to assess agreement in the diagnosis of dental fluorosis performed by a standardized digital photographic method and a clinical examination (gold standard). 49 children (aged 7-9 years) were clinically evaluated by a trained examiner for the assessment of dental fluorosis. Central incisors were evaluated for the presence or absence of dental fluorosis and were photographed with a digital camera. Photographs were presented to three pediatric dentists, who examined the images. Data were analyzed using Cohen's kappa and validity values. Agreement in the diagnosis performed by the photographic method and clinical examination was good (0.67) and accuracy was 83.7%. The prevalence of dental fluorosis was reported to be higher in the clinical examination (49%) compared with the photographic method (36.7%). The photographic method presented higher specificity (96%) than sensitivity (70.8%), a positive predictive value (PPV) of 94.4% and a negative predictive value (NPV) of 77.4%. The diagnosis of dental fluorosis performed using the photographic method presented high specificity and PPV, which indicates that the method is reproducible and reliable for recording dental fluorosis.
