Therapeutic potential of PPARα agonist in ligature-induced experimental periodontitis.
Article in Journal of applied oral science : revista FOB, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveInflammation-related immune responses and bone metabolism lead to extensive tooth loss in periodontitis.. This study aims to investigate the effect of peroxisome proliferator-activated receptor (PPAR) alpha agonist anti-inflammatory treatment in vitro and in ligature-induced experimental periodontitis in vivo . METHODOLOGY: Splenocytes were isolated from C57BL/6J mice and cultured for 48 hours under the following conditions: control, P. gingivalis lipopolysaccharide (LPS) (1 µg/ml); experimental, LPS (1 µg/ml) + PPARα agonist (fenofibrate) at 1, 10, 50, 100 µM. MRNA and secreted protein levels of TNF-α expression were detected by RT-qPCR and ELISA, respectively. Silk ligatures (7-0) were tied around maxillary second molars of C57BL/6J mice for two weeks. Optimized doses of fenofibrate (50 µM) and vehicle control were injected into the contralateral side of the palatal gingiva on days three, six, and nine. At day 14, bone resorption, osteoclastogenesis, and gingival mRNA expression levels of TNF-α, IL-1β, IL-6, and RANKL/OPG were measured by micro-computed tomography, Tartrate-resistant acid phosphatase (TRAP) staining, and Real-time quantitative PCR, respectively.
resultsTNF-α expression in cultured spleen cells were significantly increased in the presence of LPS, when compared with the control group, and significantly reduced by fenofibrate treatment in a dose-dependent manner from 1-100 µM (p<0.05). Gingival mRNA levels of TNF-α, IL-1β, IL-6, and the ratio of RANKL/OPG, were significantly decreased after injection of fenofibrate, when compared to the control side (p<0.05). Periodontal bone loss and TRAP positive cell formation were significantly decreased on the side with an injection of fenofibrate, as compared to the control side (p<0.05).
conclusionsAn anti-inflammatory treatment, PPARα agonist, inhibited inflammation and periodontal bone loss in ligature-induced experimental periodontitis.
