Resumo
A utilização do flúor como medida preventiva e terapêutica tem mudado o perfil da doença cárie dentária, no entanto o aumento da exposição a múltiplas fontes de flúor tem proporcionado uma preocupação constante sobre o aumento da prevalência e severidade da fluorose dentária. O objetivo da presente pesquisa foi analisar a ingestão total de flúor e avaliar o risco de desenvolvimento de fluorose dentária. A amostra foi composta por 55 crianças, de 18 a 36 meses de idade, que freqüentavam as creches (n=25) municipais e outras que residiam em um bairro (n=30) do município de Penedo-Al, tendo o mesmo a água de abastecimento público fluoretada. Foi aplicado, aos pais e/ou responsáveis, um questionário sobre os hábitos de higiene bucal das crianças. Para a análise da ingestão de flúor na dieta, a metodologia aplicada foi a técnica de duplicata da dieta sólida e líquida, durante dois dias consecutivos, enquanto que a ingestão de flúor pelo uso de dentifrício fluoretado foi estimada através da subtração do conteúdo de flúor contido na escova pelo conteúdo de flúor expectorado pela criança. Também foi analisada a regularidade da concentração de flúor adicionada à água da rede pública do referido município. Não existiu diferença significativa em função da ingestão total de flúor entre as crianças da creche e do bairro, respectivamente (lDP) 0,11l0,0463 e 0,09l0,0424 mgF/Kg peso/dia (Teste-t; p>0,05). A quantidade de flúor ingerida na dieta não ultrapassou a dose de risco para o desenvolvimento de fluorose preconizada de 0,05 a 0,07 mgF/Kg peso/dia. A ingestão de flúor através do dentifrício correspondeu a 64,5% do total ingerido nas creches. Fatores como: freqüência de escovação, quantidade de dentifrício colocado na escova, níveis de expectoração e a concentração de flúor solúvel do dentifrício utilizado tiveram correlação...
The use of fluoride as a preventive and as a therapeutic measure has changed the dental caries profile. However, exposure to multiple sources of fluoride and an increase in its consumption has brought about a greater and ongoing concern regarding the increase in the prevalence and incidence of dental fluorosis. The objective of this study were to assess the total fluoride ingestion by small children and the subsequent risk of developing dental fluorosis. Fifty five (55) children aged 18 to 36 months of age took past in this study. From those, 25 were enrolled in a nursery school and 30 were lifelong residents of suburbs of the city of Penedo - AL, Brazil. All children drank tap water from the public water system of Penedo, which is artificially fluoridated. All parents answered a questionnaire about the oral hygiene habits of their children. During two consecutive days all food and water ingested by each child was collected using the duplicated-plate technique. Fluoride ingestion from dentifrice was estimated by subtracting of the fluoride content in the toothbrush plus the child expectorated toothpaste-saliva slurry from the total fluoride contained in amount of toothpaste placed in the toothbrush. Fluoride in the public water system was also analyzed. There was no significant difference in total fluoride ingestion between nursery-enrolled and non-nursery-enrolled children. The meanlSD total fluoride ingestion in both groups were 0.11l0.0463 and 0.09l0.0424 mgF/Kg body weight/day, respectively (t-Test; p>0,05). Fluoride ingestion from diet did not reach the theoretical dose of 0.05-0.07 mgF/Kg body weight/day which is used to determine the risk for dental fluorosis. Fluoride ingestion from dentifrice amounted to 64.5% of total fluoride ingestion by nursery children. Factors such: toothbrushing frequency, amount of toothpaste placed in the toothbrush, quantity expectorated and ...(Complete abstract click electronic access below)
