An educational program improved mothers' knowledge and practices regarding fluorosis prevention. This led to reduced urinary fluoride levels in preschool children, decreasing their risk of dental fluorosis.
Area of Science:
- Public Health
- Pediatric Dentistry
- Preventive Medicine
Background:
- Dental fluorosis is a significant concern in preschool children.
- Maternal knowledge and practices play a crucial role in preventive oral healthcare.
- Evaluating targeted educational interventions is essential for public health strategies.
Purpose of the Study:
- To assess the effectiveness of a fluorosis educational preventive program.
- To evaluate the program's impact on maternal knowledge and practices.
- To measure changes in preschool children's urinary fluoride concentration.
Main Methods:
- A 2-group randomized field trial involving 139 mother-child pairs.
- Intervention group mothers received a fluorosis educational program; control group received no intervention.
- Maternal knowledge/practices assessed, and children's urinary fluoride measured at baseline and after six months.
Main Results:
- Mothers in the intervention group showed significant improvement in knowledge and practices related to fluorosis risk factors (p=0.006).
- A substantial decrease in urinary fluoride concentration was observed in 82.1% of children in the intervention group (p<0.001).
- No significant changes in urinary fluoride were noted in the control group.
Conclusions:
- Maternal participation in an educational program enhances knowledge and practices concerning fluorosis.
- The educational intervention effectively reduced children's urinary fluoride levels.
- Targeted educational programs can mitigate the risk of dental fluorosis in preschool children.
