The objective of this study was to estimate the intake of toothpaste fluoride used by children aged 2 to 6 years (n=87) treated at a hospital of a medium-sized city (Campina Grande, PB) in the Northeastern region of Brazil. Data regarding sociodemographic characteristics of families and children's toothbrushing were collected from questionnaire-based interviews with parents/guardians, and the amount of fluoride used during toothbrushing was estimated using a precision scale for assessment of the risk of dental fluorosis, considering a cutoff value of 0.07 mgF/kg body weight/day. Fluoride content in the toothpastes was analyzed using a specific fluoride electrode. Data were analyzed using descriptive and inferential statistics using the chi-square and Fisher's exact tests (α=0.05). Considering the use of the derice, the risk of fluorosis in the children was 19.5%. There was significant association (p<0.05) between the risk of fluorosis, brushing frequency, type of derice and who performed the child's oral hygiene. It was concluded that a high percentage of children in the studied sample used toothpaste inappropriately and were at risk of developing dental fluorosis.
本研究的目的是估算巴西东北部一个中等城市（帕拉伊巴州坎皮纳格兰德）一家医院收治的2至6岁儿童（n = 87）牙膏氟摄入量。通过对家长/监护人进行问卷调查访谈，收集有关家庭社会人口学特征和儿童刷牙情况的数据，并使用精确秤评估氟斑牙风险来估算刷牙时使用的氟量，考虑的临界值为0.07毫克氟/千克体重/天。使用特定的氟电极分析牙膏中的氟含量。使用卡方检验和费舍尔精确检验（α = 0.05）进行描述性和推断性统计分析数据。考虑到该装置的使用情况，儿童患氟斑牙的风险为19.5%。氟斑牙风险、刷牙频率、装置类型以及谁为儿童进行口腔卫生护理之间存在显著关联（p<0.05）。得出的结论是，研究样本中的高比例儿童不当使用牙膏，有患氟斑牙的风险。
