- Optimal fluoride level in the tap water was not associated with lower caries indices in the studied sample.
- Dental caries experience in examined children depended primarily on oral hygiene and diet.
- Self-declared use of at-home dental care products was associated with higher values of urinary fluoride.
Background: Successful oral health interventions must be based on the specific needs of the population that they serve. Evaluation of habits related to dental caries development and estimation of fluoride exposure in a target group of young patients helps to plan effective and safe caries prevention strategies.
Objectives: The study aimed to evaluate factors affecting dental caries experience and sources of fluoride exposure in preschool children living in two areas: with optimal and low natural content of fluoride in drinking water.
Materials and methods: The study included a group of 73 children of both sexes aged 4–7 years attending two kindergartens in Sroda Wielkopolska and Turek (Wielkopolska Voivodeship, Poland), where the content of fluoride in drinking water according to data obtained in the sanitary station ranged from 0.68 to 0.74 mg/L (optimal concentration of fluoride) and from 0.19 to 0.30 mg/L (low concentration of fluoride), respectively. Parents of patients completed a survey about diet, hygiene, and dental care, taking into account the child’s fluoride exposure. The calibrated dentist assessed the oral health condition using a mirror, a CPI probe, and a headlamp. Oral hygiene was recorded using the Silness and Loe plaque index, caries experience by calculating the numbers of decayed, missing, and filled primary, and permanent teeth (dmf and DMF, respectively) while caries frequency by calculating the percentage of children with caries experience above 0. In order to assess the fluoride concentrations in urine and drinking water, parents were asked to provide a urine sample collected on fasting and a tap water sample. Fluoride concentrations were assessed using a 09–37 (MARAT) fluoride ion-selective electrode and a RAE 111 silver-chloride reference electrode. Statistical analysis was conducted using the data analysis software system Statistica (version 12, StatSoft, Inc. 2014), assuming a statistical significance level p < 0.05.
Results: No statistically significant differences were found between caries indices of the examined children in each kindergarten (p > 0.05). Urinary fluoride levels were higher in children who tended to swallow toothpaste or used fluoride rinses and positively correlated with fluoride concentrations in the drinking water. Dental caries experience in the examined children depended on the effectiveness and frequency of oral hygiene procedures and dietary habits.
Conclusions: The strategy aimed at improving the oral health of the examined group of children should include accomplishing oral hygiene, promoting a non-cariogenic diet, and, finally, controlling fluoride exposure from at-home fluoride products. Caries prevention program ought to be adjusted to individual characteristics of each child, taking into consideration oral hygiene practices, dietary habits and total fluoride intake.

OP V – 2 Prenatal fluoride exposure and neurobehavior among children 1–3 years of age in Mexico
Background/aim Recent studies report an inverse association between fluoride (F) exposure and IQ in children, but few included individual measures of exposure or assessed associations with prenatal exposure using a prospective study design. Methods This study utilised the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) birth cohort and archived pregnancy samples
[Relationship between fluoride exposure, orthopedic injuries and bone formation markers in patients with coal-burning fluorosis].
Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan
Ossification of posterior longitudinal ligament and fluorosis.
Objective: Ossification of posterior longitudinal ligament (OPLL) is a progressive disease that causes spinal canal compromise and serious neurological sequelae in advanced cases. The incidence of OPLL in the Asiatic population is 2%-3%, but the incidence is more in the background of fluorosis. Our aim was to study the association
Urinary Fluoride Excretion after a Single Application of Fluoride Varnish in Preschool Children.
PURPOSE: To assess urinary fluoride excretion after topical application of a commercial fluoride varnish in preschool children. MATERIALS AND METHODS: Twelve healthy children, 2.5-6.0 years of age, were enrolled in a placebo-controlled cross-over trial. After a 5-day run-in period, the morning urine was collected as baseline. One hour after breakfast, 0.1
Prenatal fluoride exposure and attention deficit hyperactivity disorder (ADHD) symptoms in children at 6–12 years of age in Mexico City.
Highlights We measured urinary fluoride in 213 pregnant women living in Mexico City who were part of the ELEMENT pregnancy cohort study. Higher concentration of maternal urinary fluoride was associated with more ADHD-like symptoms in school-age children. Prenatal exposure to fluoride was most strongly associated with behavioral ratings of
