Human calculus adhesive-induced periodontitis model recapitulating human periodontitis microbiota in rats.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundPeriodontitis is a chronic inflammatory condition characterized by oral dysbiosis. Current animal models of periodontitis using ligation and pathogen inoculation are time-consuming and do not reflect the chronic characteristics of human periodontitis. One of the significant differences is the difference between the current experimental animal periodontitis microbiome and human periodontitis microbiome. This study aims to establish a humanized rat model that mimics clinical conditions and approximates the microbial causes of human periodontitis.
methodsThe human calculus adhesive-induced periodontitis (hCAP) was established by transplanting subgingival dental calculus from periodontitis patients to the subgingival surface of rats using universal adhesive. The study performed stereomicroscopy, micro-CT analysis, hematoxylin and eosin staining, tartrate-resistant acid phosphatase staining, qRT-PCR, ELISA, and 16s rDNA sequencing.
resultsThe hCAP group showed significant alveolar bone loss and osteoclast formation. The inflammatory factors in gingiva and serum were dramatically increased compared to the placebo rats, revealed by qRT-PCR and ELISA. The oral microbiota of the hCAP group was found to be more similar to that of patients compared with ligation with Porphyromonas gingivalis model, with enhanced colonization of Fusobacterium nucleatum subsp. polymorphum and Prevotella intermedia. The hCAP model also detected pathogenic bacteria of systemic diseases as shown in 16s rDNA sequencing.
conclusionsThe hCAP model mimics clinical conditions, approximates the microbial causes of human periodontitis and preserve bacteria responsible for systemic diseases in the gingival area of rats. The hCAP model may help in understanding the association between periodontitis and systemic diseases.
