Mapping Indonesian Public Discourse on Oral Health: A Content Analysis of Social Media Using Latent Dirichlet Allocation Topic Modelling.
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
backgroundThe potential of social media that offers public health insights in middle-income countries remains underexplored. This study examines patterns of oral health discourse on Indonesian social media and highlighting such insights into promotive and preventive oral health strategies.
methodsA discourse and content analysis was conducted on user-generated posts from Quora and Threads over an 18-month period (July 1, 2023-January 31, 2025). Posts were retrieved through automated data extraction and computational text retrieval based on keyword searches and coded into 19 predefined categories. Latent Dirichlet allocation (LDA) was applied to identify underlying thematic structures. Associations between platforms and discussion topics were tested using chi-square and Monte Carlo simulations. Comparative analyses examined platform-specific trends, thematic frequencies and inquiry types, with findings cross-referenced against national survey data.
resultsA total of 858 posts (541 from Quora, 317 from Threads) were analysed. The most frequently discussed issues were mouth ulcers and toothache. LDA revealed 10 dominant themes, including oral hygiene practices, children's dental visits, gum swelling and postsurgical recovery. Quora discussions were dominated by symptom-focused inquiries, whereas Threads contained more personal and emotionally expressive narratives. Statistical testing confirmed a significant association between platform type and topics discussed (P < .001).
conclusionThis study demonstrated the utility of automated data extraction and LDA-based thematic modelling in uncovering community-level oral health patterns. Social media provides an immediate context-relevant perspective for monitoring oral health needs, supporting targeted communication strategies and responsive public health interventions. CLINICAL RELEVANCE: This study introduces a complementary approach to conventional epidemiological monitoring. The findings can guide policymakers and practitioners in developing targeted preventive initiatives and public engagement strategies for improved oral health outcomes.
