Abstract

Hypertension and periodontitis are highly prevalent among African Americans. This cross-sectional study investigated the relationships among inflammatory biomarkers in the gingival fluid, periodontitis, and blood pressure in these individuals. Twenty-one subjects who reported a diagnosis of hypertension and a comparison group of 26 nonhypertensive participants were enrolled. All were African Americans, non–cigarette smoking, and free from other systemic illness. Blood pressure and body mass index were assessed. A comprehensive periodontal examination was performed. Gingival fluid was collected from 3 healthy sites and 3 diseased sites when available. Samples were assessed for 8-isoprostane, interleukin 1β, monocyte chemoattractant protein 1, tumor necrosis factor-alpha (TNFα), C-reactive protein (CRP), and matrix metalloproteinase 8. Regardless of hypertension status, diseased sites were associated with increased levels of these biomarkers. CRP and TNFα levels were also significantly higher in hypertensive than nonhypertensive individuals without diseased sites. After adjusting for demographics and body mass index, periodontal attachment loss was higher among hypertensive than nonhypertensive subjects. TNFα and CRP levels and hypertension were in the same association pathway with attachment loss. Elevated blood pressure may increase the risk of periodontitis through a localized inflammatory mechanism. Knowledge Transfer Statement: The results of this study can be used by clinicians to better understand the etiology and pathogenesis of periodontitis in hypertensive individuals in general and African Americans in particular. The information could lead to better management of periodontal disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Patients with hypertension presented with almost twice as much periodontal clinical attachment loss as controls (mean ± SEM: 0.87 ± 0.13 vs 0.49 ± 0.11).

    “In addition, patients with hypertension presented with almost twice as much periodontal clinical attachment loss (CAL) as controls (Mean þ SEM in HTN = 0.87 ± 0.13 vs. non-HTN = 0.49 ± 0.11).”
  • In patients with periodontal pockets, increased levels of 8-isoprostane, IL-1B, MCP-1, TNFa, CRP, and MMP-8 were observed independent of hypertension status.

    “They reported that independent of hypertension present or absent, an increased level of these biomarkers was observed when patients had periodontal pockets.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
