A Longitudinal Study of Antimicrobial Resistance in Oral Bacterial Isolates From Periodontitis Patients in Taiwan.
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
INTRODUCTION AND
aimsThe oral cavity harbours a complex microbial ecosystem that plays a critical role in periodontal health and disease. Despite growing concerns over antimicrobial resistance (AMR), long-term surveillance of antibiotic susceptibility in oral bacteria remains limited. This study aimed to assess the temporal trends in AMR among oral bacteria isolated from periodontitis patients in Taiwan over a 14-year period, with emphasis on genus-specific, Gram-specific, and sex-related patterns.
methodsA total of 980 bacterial isolates were obtained from 466 periodontitis patients between 2008 and 2021. E-strip testing was performed for six antibiotics: amoxicillin, ciprofloxacin, clindamycin, metronidazole, minocycline, and amoxicillin-clavulanic acid. Susceptibility data were analysed by year and bacterial genus.
resultsPolymicrobial infections were predominant (98.1%), and resistance rates increased significantly over time, particularly for metronidazole (from 37.8% to 90.9%) and ciprofloxacin (from 33.1% to 51.5%). Streptococcus, Peptostreptococcus, and Capnocytophaga were more prevalent in females, while Neisseria, Fusobacterium, and Pseudomonas were more common in males. High resistance rates were observed in Neisseria, Escherichia, and Staphylococcus, with over 80% of some isolates resistant to multiple agents.
conclusionOur findings reveal a progressive rise in AMR among oral bacteria and highlight the need for localized antibiotic stewardship in dentistry. This is the first long-term oral AMR surveillance study in Taiwan and offers a foundation for updating empirical treatment guidelines and informing public health policy. CLINICAL RELEVANCE: This study provides long-term, real-world AMR data for oral bacteria in Taiwan. The findings support more informed antibiotic selection in periodontal therapy and highlight the need to re-evaluate empirical use of metronidazole and fluoroquinolones in routine dental practice.
