Development and validation of a questionnaire about fluoride knowledge.
Article in Brazilian dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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.
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
objectiveTo develop and validate a questionnaire about fluoride knowledge (FKQ).
methodsQuestions to evaluate knowledge about fluoride sources and daily fluoridated water and dentifrices consumption were developed and validated. Sociodemographic data were also collected from the participants, and data were collected for testing their psychometric properties and instrument validation. The model adjustment was tested in 456 dentists, students, and health personnel via confirmatory factor analysis (CFA) with unidimensional categorical indicators. Cronbach's alpha coefficient was used to estimate the instrument's reliability. External validation measurements were represented by questions related to sociodemographic data, fluoride source knowledge and daily practices, and the consumption of fluoride water and dentifrices.
resultsThe model showed adequate fit via confirmatory factor analysis (CFA); the fit indices were comparative fit index (CFI) = 0.941, Tucker‒Lewis index (TLI) = 0.927, and root mean square error of approximation (RMSEA) = 0.075, with factorial loadings varying between 0.25 and 0.91. The Cronbach's alpha coefficient for the 13 items was 0.68, demonstrating substantial and adequate reliability in the total instrument.
conclusionThe FKQ can estimate the knowledge of dentists, dental students, and health personnel about fluoride use.
