Relationship Between Smartphone Use and Traumatic Tooth Fractures in Korean Adolescents.
Article in International journal of paediatric dentistry, 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
backgroundWith the increasing rate of smartphone use among adolescents, smartphone addiction has become a social issue, causing reduced attention. This may make adolescents more susceptible to traumatic dental injuries (TDIs).
aimTo assess the association between smartphone use and TDIs among Korean adolescents.
designThis study used open-source data from the 2023 Korea Youth Risk Behavior Survey. This study included responses from 52 875 Korean adolescents. Information on demographics, weekly smartphone use, weekly exercise days, and tooth fracture experiences in the past year was collected and analyzed.
resultsThe mean smartphone use per week was 2146.91 ± 1276.60 min in all participants, and the frequency of tooth fractures was 9.3% in extremely low users, 10.1% in low users, 11.1% in excessive users, and 13.6% in extremely excessive users. Logistic regression analysis revealed that higher smartphone usage time correlated with a greater risk of tooth fracture by increasing odd ratios for low, excessive, and extremely excessive users compared to excessively low users.
conclusionsWithin the limitations of this study, increased smartphone use was associated with higher rates of tooth fracture in Korean adolescents. This finding suggests the potential role of smartphone use in contributing to TDIs.
