Next-generation sequencing improves pathogen identification in odontogenic abscesses, could this affect clinical outcomes?
Review in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectivesThis study aimed to evaluate the diagnostic performance of gene-based bioinformatic analysis via next-generation sequencing (NGS) compared to conventional culture and microscopy in identifying microorganisms and antibiotic resistances in odontogenic abscesses. Additionally, the influence of selected clinical indicators including prior antibiotic therapy, in-hospital antibiotic treatment, and detection of antibiotic resistance on length of stay (LOS) was analysed. MATERIALS AND
methodsIn patients undergoing extraoral incision and drainage of odontogenic abscesses at the Department of Oral and Maxillofacial Plastic Surgery, University Hospital Bonn, two microbiological swabs (NGS and conventional) were taken intraoperatively from each patient. Microbial profiles and resistance patterns were assessed and correlated with clinical data.
resultsBacteria were identified in 100% of NGS swabs compared to 68.1% in conventional swabs (p < 0.001). NGS detected a median of 8 bacterial genera per sample versus 1 via conventional methods, primarily due to superior detection of anaerobes (median 7 vs. 0). Both methods equally identified aerobic genera (median 1 each). Fungal organisms and antibiotic resistances were also more frequently detected using NGS (p < 0.001). Prior antibiotic therapy was associated with a significantly reduced LOS (p = 0.030). Neither the type of in-hospital antibiotic regimen nor the presence of resistance influenced LOS.
conclusionsNGS substantially enhances the detection of polymicrobial communities, including anaerobes and fungi, and identifies antibiotic resistances more effectively than conventional diagnostics in odontogenic abscesses. CLINICAL RELEVANCE: NGS offers rapid, comprehensive pathogen profiling and resistance testing, supporting quick establishment of tailored antimicrobial therapy.
