Social listening for the identification of information voids on early childhood caries based on Google search data.
Article in European archives of paediatric dentistry : official journal of the European Academy of Paediatric Dentistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
purposeThis study aims to identify possible early childhood caries (ECC)-related information voids in different countries using both quantitative and qualitative approaches.
methodsData were collected from the Google Trends platform using topics related to a taxonomy previously developed. Searches were analyzed for two time periods: the last 7 days and the last 30 days before the data collection dates. Two independent investigators classified search data from 21 countries as either related to ECC or not. For ECC-related terms, relative search volume, relative velocity, and relative acceleration were calculated. In addition, question-like search queries were identified for each topic and country.
resultsPotential information voids were identified across nine themes: teeth cleaning, dental floss, toothbrush, oral hygiene, poor oral hygiene, antibiotics, baby bottle, dental caries, and child oral health. The topics dental caries, dental floss, toothbrush, teeth cleaning, and oral hygiene showed the highest search volumes, relative velocities and accelerations. Mexico, Brazil, and France were the countries with the highest number of ECC-related search topics. The most frequent question-like queries included "what is dental caries," "how to use dental floss," "how to brush teeth," "how long to brush teeth," and "what is oral health."
conclusionsThis study identified potential ECC-related information voids across multiple countries, revealing persistent public uncertainties concerning specific aspects of dental caries. The findings can inform more effective health communication strategies to strengthen digital health literacy and prevent the widespread dissemination of misinformation.
