An interventional study of multicomponent intervention and Conventional intervention in Fluorosis, Dental and Fluorosis, sponsored by Universidad Antonio Nariño. Enrolling by invitation at 1 site in Colombia. Open to participants aged 2 Years to 5 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-01-22.

Introduction Systemic exposure to fluoride is a significant challenge for global public health; this is because although fluoride prevents dental caries, prolonged exposure to high concentrations can cause adverse effects on various organs and systems, especially the teeth. Despite the existence of preventive strategies to reduce this exposure, evidence on the effectiveness of multicomponent interventions is limited. This protocol describes the design of a randomized controlled trial to evaluate the effects of a multicomponent intervention on parents and children to reduce the risk of exposure to high concentrations of fluoride in children. Methods This is a randomized controlled trial, and kindergartens in the municipalities of the Department of Huila, Colombia, will be recruited. The intervention group will receive a comprehensive five-component program: installation of water filters to reduce fluoride consumption; educational sessions for parents and children to raise awareness and promote healthy practices; outreach activities to strengthen collective knowledge; and a maintenance phase to ensure the program's sustainability. In contrast, the control group will participate in a conventional educational strategy focused on the parent-child dyad. Measurements will be taken at four points in time: pre-intervention for baseline and post-intervention at 3, 6, and 12 months. The evaluation of results includes the concentration of fluoride in children's urine, fluoride levels in water (to validate the effectiveness of filtration), and changes in parents' knowledge, attitudes, and practices. Discussion The trial will evaluate the effectiveness of a multicomponent intervention aimed at parents and children to reduce the risk of fluoride exposure. Through integrative methodological approaches and objective measurements, it will demonstrate significant improvements in reducing fluoride exposure in children and in parents' knowledge, attitudes, and practices. It will contribute to child health programs, strengthen preventive oral health strategies with an impact on public policy, community health, and new lines of research on fluoride.
Exclusion Criteria:
multicomponent intervention
Behavioral: multicomponent intervention
Conventional intervention
Behavioral: Conventional intervention
1\. Installation of physical barriers: a reverse osmosis water filter. 2. Educational sessions for parents: three thematic modules. 3. Educational sessions for children: one thematic modules. 4. Outreach activities: To ensure the sustainability of the intervention. 5. Maintenance phase: The population will have free access to educational resources through the "Camaleón Sonriente cuida tus dientes" (Smiling Chameleon Takes Care of Your Teeth)
The intervention will include training on the cariogenic diet, flossing, and hand washing.
Urinary fluoride concentrations
Decrease in urinary fluoride concentrations in children
Time frame: Time Frame: Baseline, 3 , 6, and 12 months.
Knowledge, attitudes, and practices (KAP)
To assess changes in parents' knowledge and attitudes, the Knowledge, Attitudes, and Practices (KAP) survey will be administered, after validation. The instrument was designed for this purpose, taking into account the components of the intervention. The knowledge section consists of 12 items and explores parents' understanding of natural and non-natural sources of fluoride and its effects on oral and systemic health. The attitudes section consists of 10 items and identifies perceptions, beliefs, motivations, and willingness to act in response to fluoride risk, water quality, willingness to change habits, and dental follow-ups. The practices section, with 9 items, addresses information on current behaviors related to consulting fluoride content, modifying water sources, dental care, and supervision in the use of dental products. Each section of the instrument includes ordinal scale variables and provides an overall score that allows each section to be classified as good, fair, or poor.
Time frame: Time Frame: Baseline, 3 , 6 and 12 months.
Fluoride concentrations in water
Reduction in fluoride concentrations in water.
Time frame: Time Frame: baseline, 3, 6, and 12 months
