Assessment of internet data on orthodontic treatment and oral hygiene in the Marmara region using Google Trends:a methodological study.
Article in European oral research, 2025. 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
Purpose: This study aims to examine the relationship between Google Trends (GT) data on orthodontics and oral hygiene terms from 2019, 2020, and 2021 and the gross domestic product (GDP) and population of cities in the Marmara Region. Materials and methods: GDP, population, and GDP per capita data for Turkiye and the Marmara Region were collected. Using GT, searches for orthodontics, brackets, clear aligners, orthodontic toothbrush, toothpaste, and tooth decay were analyzed for 2019-2021. GT values for Turkiye and Marmara cities were recorded. The Kruskal-Wallis test was used for group comparisons, followed by Dunn's test for identifying significant differences. Spearman's rho correlation analysis assessed relationships between parameters. Results: In 2021, the GT score for toothpaste was significantly higher than in 2019-2020 (p < 0.05). In 2019, clear aligner and tooth decay GT scores showed a positive, significant correlation with GDP (p < 0.05). In 2020 and 2021, braces, clear aligner, and tooth decay GT scores also correlated positively with GDP (p < 0.05). A consistent positive correlation between clear aligner and dental caries was observed across all three years (p < 0.05). Conclusion: GT data demonstrate its potential as a valuable tool for epidemiological research, digital data management, and evidence-based analysis. Findings suggest that individuals in higher GDP provinces are more likely to search for advanced orthodontic treatment, particularly clear aligners.
