Symptoms and Knowledge of Dental Erosion Among Hong Kong Adults.
Article in International dental journal, 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
objectiveThis study investigates self-reported symptoms and knowledge of dental erosion among adults in Hong Kong.
methodsA 2-week online self-administered closed-ended questionnaire was conducted in 2025, with pre-verified panel members aged 25 to 45 years invited via the Hong Kong Public Opinion Research Institute's online platform. The questionnaire collected demographic data, medical and dental history, self-reported symptoms, dietary habits, dental visits, management strategies for dental hypersensitivity, and knowledge about dental erosion. Multivariable binary logistic regression was performed to identify independent risk factors for high symptom burden (≥3 symptoms).
resultsOf the 2311 participants, 96% reported self-reported symptoms potentially related to dental erosion, with 1452 valid questionnaires analyzed. Among these, 50% were middle-aged (35-45 years) and 55% were female. The 2 most common symptoms were yellowing teeth (76%) and temperature or acid sensitivity (65%), with 36% reporting at least 3 of the 5 symptoms. Many (44%) had experienced symptoms for at least 3 years, but only 38% sought dental consultation. Almost half (41%) of participants had never heard of dental erosion, and among those aware, only 22% correctly answered all 3 knowledge questions. The median daily eating/drinking frequency was 6, with 20% reporting ≥9 episodes daily. Multivariable analysis identified middle age (aOR = 1.608, p < .001), acid reflux (aOR = 1.655, p = .001), frequent sour snack consumption (aOR = 4.658, p < .001), and frequent juice/fruit vinegar intake (aOR = 1.429, p = .041) as independent risk factors for high symptom burden. CLINICAL SIGNIFICANCE: This study highlights the need for increased public awareness and early intervention strategies to prevent dental erosion and its associated complications among Hong Kong adults.
