1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

objectivesCommunity water fluoridation (CWF) is a widely used population-level intervention for preventing dental caries. However, CWF discontinuation is increasingly debated globally, often without a comprehensive synthesis of the subsequent clinical, service-related, economic, and equity implications. We aimed to systematically map and synthesize empirical evidence regarding dental health and service-based outcomes following CWF cessation.

methodsFor this scoping review, we searched 17 bibliographic databases and grey literature from inception through Oct 31, 2025. Eligible studies reported empirical dental outcomes, including caries indices, service utilization, and treatment costs, before and after CWF cessation or compared outcomes in ceased communities with those in appropriate control communities. Data were extracted independently by multiple reviewers, and overlapping cohorts were linked into evidence clusters to avoid double-counting findings.

resultsNineteen studies (1970-2025) conducted in Europe, North America, Australia, and Israel were included. Findings were heterogeneous across settings and study designs. Jurisdictions without active fluoride replacement programs more frequently reported increases in caries measures, including up to a 75% increase in mean DMFT, and increased treatment utilization, particularly restorative procedures. By contrast, settings with alternative fluoride strategies or broader preventive infrastructure often reported stable outcomes or continued improvements over time. Several studies also reported greater treatment burden and costs, including a 32% increase in caries-related expenditures, among younger children and selected vulnerable populations, including socioeconomically disadvantaged groups and publicly insured children.

conclusionsOral health outcomes following CWF cessation varied across settings and populations. Little change or continued improvement was more commonly observed in settings with broader preventive supports or alternative fluoride strategies, whereas greater treatment burden and less favorable outcomes were more frequently reported among younger or vulnerable populations and in settings with limited preventive supports. More rigorous comparative research is needed to clarify these relationships and inform policy decisions.
