ABSTRACT
Abstract: Purpose: to evaluate the effect of dentifrice pH and fluoride concentration ([F]) on fluoride uptake on the biofilm and nails of children from a non-fluoridated area. Methods: two hundred and twenty-eight two- to four-year-old children were randomly allocated into 3 groups according to the type of dentifrice: G1: 1100 μg F/g, pH 4.5 (n = 76); G2: 750 μg F/g, pH 4.5 (n = 74); and G3: 1100 μg F/g, pH 7.0 (n = 78). Nails were collected at 4, 8, and 12 months after starting dentifrice use and biofilm was collected 5 and 60 minutes after toothbrushing. The concentrations of F in nails and biofilm were analyzed by HMDS facilitated diffusion. Data were analyzed by Kruskal-Wallis/Mann-Whitney's test and the comparison between biofilm collection times was done using Wilcoxon test (p £ 0.05). Results: a significant reduction of [F] in biofilm was observed 60 minutes after toothbrushing, regardless of the dentifrice used. However, 5 minutes after toothbrushing, G1 had a significantly higher [F] compared to G2 and G3, and 60 minutes after toothbrushing, [F] was significantly higher for G1 and G2 compared to G3. G1 and G3 had significantly higher [F] in the nails compared to G2. Conclusion: a lower dentifrice concentration is a relevant factor for the reduction of excessive fluoride intake. The use of a low-F acidified dentifrice combines the reduction of fluoride uptake with caries prevention by leading to greater incorporation of F into the biofilm over time.
ABSTRACT
O Cirurgião-Dentista tem a obrigação ética e legal na identificação/notificação dos casos de maus-tratos. Objetivo: Objetivou-se com esse estudo analisar o conhecimento dos Odontopediatras da cidade de João Pessoa-PB sobre maus-tratos infantis. Tratou-se de um estudo quantitativo, exploratório, bibliográfico e descritivo. O universo dessa pesquisa compreendeu 44 Cirurgiões-Dentistas regularmente inscritos no Conselho Regional de Odontologia da Paraíba, com especialidade em Odontopediatria, em qualquer faixa etária de ambos os sexos. Para realização do cálculo amostral foi considerado grau de confiança de 95%, ficando uma amostra de 40 Odontopediatras. Métodos: Aplicou-se um questionário com 11 questões que atendiam aos objetivos da pesquisa. Os dados coletados foram tabulados em uma plataforma do Microsoft Excel e analisados mediante estatística descritiva (valores de frequência absoluta e percentual) no software IBM SPSS (21.0). Resultados: A maioria dos profissionais é do sexo feminino (93,5%) e 48,39% têm mais que a 4a década de vida. 51,61% definiram maus-tratos infantis de forma incompleta, 51,6% classificaram de forma completa, conforme a Associação Brasileira Multiprofissional de Proteção à Infância e à Adolescência; os sinais/sintomas bucais mais citados foram fraturas dentárias (41,07%), queimaduras (21,43%), lacerações (14,29%) e hemato¬mas (12,5%); já os sinais/sintomas corporais mais citados foram hematomas (35,6%), queimaduras (20,34%), fraturas (15,25%) e lacerações (10,17%). A maioria dos pesquisados relatou saber agir diante de casos de maus-tratos (93,5%), entre eles 76,92% denunciariam ao conselho tutelar e 54,8% demonstram interesse em capacitação. Conclusão: De forma geral, houve conhecimento parcialmente satisfatório dos Odontopediatras inscritos no CRO-PB sobre maus-tratos infantis.
The Dentist has ethical and legal obligation to identify/report cases of abuse. Objective: The objective of this study is to analyze the knowledge of dentists in the city of João Pessoa-PB-Brazil, on child abuse. The research carried out a quantitative, exploratory, bibliographic and descriptive study. The research universe comprises 44 pediatric dentists regularly registered in the Regional Council of Dentistry, specialized in pediatric dentistry in any age group of both genders. For performing the sample calculation was considered a confidence level of 95%, getting a sample of 40 dentists. Methods: They received a questionnaire with 11 questions that met the research objectives. The collected data were typed into a Microsoft Excel platform and analyzed using descriptive statistics (absolute and percentage frequency values) in IBM SPSS software (21.0). Results: Most professionals are female (93,5%), (48,39%) of these corresponded to more than four decades of life. 51.61% of the interviewed people defined child abuse incompletely, 51.6% rated child abuse completely, signs/symptoms most cited were oral dental fractures (41.07%), burns (21.43%), lacerations (14.29%) and he¬matomas (12.5%), the physical signs/symptoms most cited were hematomas (35.6%), burns (20.34%), fractures (15.25%) and lacerations (10.17%). 93.5% of respondents would know how to act on cases of child abuse, among them 76.92% would denounce the tutelary assistance and 54.8% have an interest in training. Conclusion: Overall, there was partially adequate knowledge of the registered dentists in the CRO-PB on child abuse.
