Can angiotensin II affect the inflammatory response of human dental pulp cells in vitro?
Article in Journal of applied oral science : revista FOB, 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
objectiveThis study aimed to evaluate the capacity of fibroblasts from permanent and deciduous dental pulp to express inflammatory mediators when exposed to bacterial and inflammatory antigens. It also sought to assess the presence of components of the renin-angiotensin system (RAS) and the potential modulatory role of ANG-II in this response. METHODOLOGY: Fibroblasts were cultured from the pulp of permanent and deciduous teeth obtained from three adult and four pediatric donors with informed consent. Cells were stimulated with Porphyromonas gingivalis and Escherichia coli lipopolysaccharides (LPS) either alone or in combination with ANG-II and, in some cases, with IL-1β. Gene expression of RAS components and various inflammatory mediators was analyzed by qRT-PCR. ANG-II receptor expression was quantified by flow cytometry.
resultsThe results showed that both bacterial antigens and IL-1β significantly upregulated the expression of genes encoding key inflammatory mediators. However, ANG-II, either alone or in combination with other antigens, failed to alter the expression levels of these mediators.
conclusionThese findings clearly show that ANG-II has no influence on the expression of inflammatory mediators by human dental pulp fibroblasts under the tested conditions.
