BACKGROUND: Israel's community water fluoridation policy, mandatory from 2002 until its halt in 2014, provides a natural experiment to assess fluoridation's impact on pediatric oral health. This retrospective study analyzed digital dental records of 12-year-old children (2014-2022) to assess changes in caries experience following community water fluoridation cessation.
METHODS: We examined the Decayed, Missing, and Filled Teeth index, focusing on its Missing-and-Filled (MF) component, across socioeconomic status groups, gender, and fluoridation status (fluoridated vs. non-fluoridated). Differences were assessed using one-way Welch ANOVA and post-hoc Games-Howell tests.
RESULTS: The MF index increased significantly after fluoridation ended, especially in low-SES populations. Twelve-year-olds in low-SES communities without fluoridated water had more than double the caries experience of those in high-SES communities (mean MF 0.82 vs. 0.40; p < 0.05). Fluoridated communities showed a considerably narrower SES gap. SES had a large effect on caries outcomes (partial η²≈0.34), and the absence of fluoridation was associated with a modest but significant increase in MF (partial η²≈0.01). Females exhibited higher MF rates than males, with gender disparities more pronounced in non-fluoridated groups. Cessation of CWF was associated with a rise in caries and widened SES and gender disparities, underscoring fluoridation's value in promoting oral health equity.
CONCLUSION: CWF remains a foundational public health measure, one that is unequaled in its ability to deliver effective, safe, equitable, and cost-saving caries prevention to entire populations.
PRACTICAL IMPLICATIONS: Reinstating mandatory community water fluoridation is essential to reverse the widening oral health disparities that disproportionately affect low-SES children and females. Policymakers must prioritize this measure to restore health equity and protect vulnerable populations who rely on this passive preventive intervention.
