Effect of ridge preservation at molar extraction sites with severe periodontitis on the Schneiderian membrane thickness changes: a pilot study.

BMC Oral Health 2021 Apr 12;21(1):184. Epub 2021 Apr 12.

Department of Restorative Dentistry, University of Washington, Seattle, WA, USA.

Background: Information regarding the reaction of bone augmentation in terms to sinus mucosa thickness of periodontally compromised molar extraction sites is limited. This retrospective study aimed to analyze the effect of ridge preservation procedures following the extraction of molars with severe periodontitis on the healing pattern of adjacent maxillary sinus mucosal membranes.

Methods: Thirty-one periodontally compromised maxillary molar teeth either receiving ridge preservation (test group, n = 20) or undergoing spontaneous healing (control group, n = 11) were investigated. Read More

Matrix metalloproteinase-7 in periodontitis with type 2 diabetes mellitus.

J Periodontal Res 2018 Oct 4;53(5):916-923. Epub 2018 Jul 4.

Department of Periodontology, Institute of Dentistry, University of Turku, Turku, Finland.

Background And Objective: Elevated levels of matrix metalloproteinase-7 (MMP7) have been observed in serum samples of subjects with type 2 diabetes mellitus (T2DM) and in gingival tissues of subjects with periodontitis. The aim of the present study was to collect in vivo and in silico evidence on the role of MMP7 in the interplay between T2DM and generalized periodontitis (GP).

Material And Methods: The extent of MMP7 expression and localization were immunohistochemically analyzed in gingival tissues of patients with GP with T2DM (T2DM/GP, n = 11), systemically healthy patients with GP (n = 7), and systemically and periodontally healthy controls (n = 11). Read More

Salivary Myeloperoxidase, Assessed by 3,3'-Diaminobenzidine Colorimetry, Can Differentiate Periodontal Patients from Nonperiodontal Subjects.

Enzyme Res 2016 5;2016:7517928. Epub 2016 May 5.

Department of Biochemistry, Faculty of Medicine, Khon Kaen University, Khon Kaen 40002, Thailand.

Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Read More

Gingival crevicular fluid levels of interferon-γ, but not interleukin-4 or -33 or thymic stromal lymphopoietin, are increased in inflamed sites in patients with periodontal disease.

J Periodontal Res 2014 Feb 1;49(1):55-61. Epub 2013 Apr 1.

Department of Periodontology, Tufts University School of Dental Medicine, Boston, MA, USA.

Objective: To investigate the hypothesis that levels of interferon (IFN)-γ and interleukin (IL)-4, as well as the newer cytokines IL-33 and thymic stromal lymphopoietin (TSLP), in gingival crevicular fluid (GCF) samples differ from sites of patients at various clinical stages of periodontal disease and controls.

Background: Periodontal diseases result from the complex interplay between pathogenic bacteria and the host's immune responses. Several inflammatory mediators, such as IFN-γ and IL-4, have been detected in GCF samples in patients with periodontitis, but the results are mostly contradicting due to the lack of uniformity and collection of sites and methods of analysis.

Activation of the neutrophil respiratory burst by plasma from periodontitis patients is mediated by pro-inflammatory cytokines.

J Clin Periodontol 2011 Jan 21;38(1):1-7. Epub 2010 Oct 21.

School of Life and Health Sciences, Aston University, Birmingham, UK.

Aim: To determine the effect of periodontitis patients' plasma on the neutrophil oxidative burst and the role of albumin, immunoglobulins (Igs) and cytokines.

Materials And Methods: Plasma was collected from chronic periodontitis patients (n=11) and periodontally healthy controls (n=11) and used with/without depletion of albumin and Ig or antibody neutralization of IL-8, GM-CSF or IFN-α to prime/stimulate peripheral blood neutrophils, isolated from healthy volunteers. The respiratory burst was measured by lucigenin-dependent chemiluminescence. Read More

Salivary-soluble CD44 levels in smokers and non-smokers with chronic periodontitis: a pilot study.

J Periodontol 2010 May;81(5):710-7

Department of Oral Medicine, Periodontology and Diagnosis, Faculty of Oral and Dental Medicine, Cairo University, Cairo, Egypt.

Background: Smoking is the most important environmental risk factor for periodontal disease. Elevated levels of serum-soluble CD44 (sCD44) have been detected in smokers and also have been recognized as a diagnostic marker in some smoking-induced diseases. The present study investigates the salivary sCD44 profiles of smokers and non-smokers with and without chronic periodontitis in response to scaling and root planing (SRP). Read More

Grapefruit consumption improves vitamin C status in periodontitis patients.

Br Dent J 2005 Aug;199(4):213-7, discussion 210

Department of Conservative Dentistry, Friedrich Schiller University, An der alten Post 4, 07750 Jena, Germany.

Objective: Previous studies demonstrate a relationship between a lack of vitamin C and increased risk of periodontal disease. In the present study we examine the vitamin C plasma levels and inflammatory measures in periodontitis patients before and after the consumption of grapefruit.

Subjects And Methods: Fifty-eight patients with chronic periodontitis were assigned to the test group (non-smokers n=21, smokers n=17) and a diseased control group (non-smokers n=11, smokers n=9). Read More

The effect of aspirin on the periodontal parameter bleeding on probing.

J Periodontol 2002 Aug;73(8):871-6

Departments of Pediatric Dentistry and Orthodontics, UCLA School of Dentistry, Los Angeles, CA, USA.

Background: The absence or presence of bleeding on probing (BOP) is a sign of periodontal health or disease, but the presence of BOP is not an accurate predictor of disease progression. Aspirin is increasingly used in the prevention of cerebrovascular and cardiovascular diseases and is a non-disease factor that may modify bleeding indices given its antithrombolytic activity. The purpose of this double-blind placebo-controlled randomized clinical trial was to study the effect of short-term daily aspirin ingestion on the clinical parameter BOP. Read More
