Identifying patients with a strong pro-inflammatory phenotype may allow clinicians to underpin high-risk individuals based on early inflammatory marker profiles and to personalize approaches to preventative treatments. The objective of this systematic review is to synthesize the results of previous studies on osseointegration to show which pro-inflammatory cytokines and chemokines have been detected and quantified during the initial phase of osseointegration. PubMed, Embase, Scopus, ISI Web of Science, and Cochrane Library were searched for articles published until August 2024.

Article Synopsis
  • The study investigated how varying surface roughness of titanium alloy Ti6Al4V and zirconia affects neutrophil activity.
  • Rougher surfaces (Ra > 3 µm) led to significantly higher expression of elastase (NE) and matrix metalloproteinase (MMP)-8 compared to very smooth surfaces (Ra < 0.1 µm).
  • Additionally, rough surfaces promoted greater formation of extracellular traps (NETs) by neutrophils over time.

Periodontitis (P), a chronic inflammatory condition that affects the supportive tissues around the teeth, is three to four times more prevalent in individuals with diabetes mellitus (DM), with a direct correlation between its severity and the levels of glycosylated hemoglobin (HbA1c). This study aimed to evaluate the periodontal clinical parameters following non-surgical periodontal treatment (NSPT) in P patients with or without type 2 DM. : Forty patients with P were divided into two groups: Group DM/P and Group P.

We sought to evaluate the effects of non-surgical periodontal treatment (NSPT) on periodontal clinical parameters, systemic blood pressure (BP), and plasma levels of systemic inflammation markers in patients with combined refractory arterial hypertension (RAH) and stage III grade B periodontitis. Twenty-seven participants with RAH and periodontitis received NSPT. The analyzed clinical parameters were probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI).

The purpose of this in vitro study is to evaluate the effectiveness of incorporating a new irrigation system into a surgical guide and monitor its effect on heat generation during implant bed preparation. A total of 48 surgically guided osteotomies were performed on 12 bovine ribs divided into 4 groups, using different irrigation techniques: Group A (test) had entry and exit channels incorporated into the guide; Group B had a similar design with an entry channel only; Group C had conventional external irrigation; and Group D (control) had no irrigation. Heat generation during the osteotomies was measured using thermocouples placed at a depth of 2 mm and 6 mm.

Objectives: This systematic review aimed to assess in vitro studies that evaluated neutrophil interactions with different roughness levels in titanium and zirconia implant surfaces.

Material And Methods: An electronic search for literature was conducted on PubMed, Embase, Scopus, and Web of Science and a total of 14 studies were included. Neutrophil responses were assessed based on adhesion, cell number, surface coverage, cell structure, cytokine secretion, reactive oxygen species (ROS) production, neutrophil activation, receptor expression, and neutrophil extracellular traps (NETs) release.

Purpose: We aimed to investigate the impact of nonsurgical periodontal treatment combined with one-year dietary supplementation with omega (ω)-3 on the serum levels of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), docosapentaenoic acid (DPA), and arachidonic acid (AA).

Methods: Fifteen patients with chronic generalized periodontitis were treated with scaling and root planing. The test group consisted of seven patients (43.

Aim: To evaluate the effects of non-surgical periodontal treatment on left ventricular mass (LVM), arterial stiffness, systolic and diastolic blood pressure and plasma levels of inflammatory markers (C-reactive protein (CRP), fibrinogen and interleukin-6) in refractory hypertension patients.

Material And Methods: This interventional prospective cohort pilot study included 26 patients (53.6 ± 8.

Objective: To analyze the subgingival microflora composition of inflammatory bowel disease (IBD) patients with untreated chronic periodontitis and compare them with systemically healthy controls also having untreated chronic periodontitis.

Method: Thirty IBD patients [15 with Crohn's disease (CD) and 15 with ulcerative colitis (UC)] and 15 control individuals participated in the study. All patients had been diagnosed with untreated chronic periodontitis.

Objective: The aim of this study was to investigate the effect of periodontal therapy on the circulating concentration of high-sensitivity capsule-reactive protein (hs-CRP), fibrinogen (FIB), interleukin (IL)-4, IL-6, IL-8, IL-10 and tumour necrosis factor-alpha (TNF-alpha) and on the metabolic control in type 2 diabetes mellitus (T2DM) patients.

Material And Methods: Twenty-three T2DM patients with chronic periodontitis were enrolled in this study. Periodontal clinical parameters, namely visible plaque index, gingival bleeding index, bleeding on probing, probing depth and clinical attachment levels, were evaluated.

Background: Recent epidemiologic studies suggest that inflammation is the link between periodontal diseases and cardiovascular complications. This study aimed to evaluate the effects of non-surgical periodontal treatment on plasma levels of inflammatory markers (interleukin [IL]-6, C-reactive protein [CRP], and fibrinogen) in patients with severe periodontitis and refractory arterial hypertension.

Methods: Twenty-two patients were examined and randomly divided into two groups.

Background: This study aimed to compare the effectiveness of non-surgical periodontal treatment in improving periodontal status and reducing gingival crevicular fluid (GCF) levels of interleukin (IL)-1beta and IL-18, elastase activity, and matrix metalloproteinase (MMP)--8 and --9 in periodontitis patients with and without type 2 diabetes mellitus (T2DM).

Methods: Twenty-three patients with T2DM (diabetes group) and 26 systemically healthy subjects (control group) with chronic periodontitis participated in this study. The clinical examination included visible plaque index, gingival bleeding index, probing depth, clinical attachment level, and bleeding on probing.

Purpose: Our aim was to evaluate the expression of interleukin-18 (IL-18), interleukin-l-beta (IL-1beta) and the amount of elastase activity in gingival crevicular fluid (GCF) from inflamed gingival sites in patients with juvenile systemic lupus erythematosus (JSLE), and compare these to the expression in GCF from inflamed sites in generally healthy controls. In addition, the local inflammation in periodontal tissues was related to systemic inflammation by the assessment of IL-18 levels in plasma.

Materials And Methods: GCF from 16 patients with JSLE and 14 controls were collected using a washing device.

Background: Patients with juvenile idiopathic arthritis (JIA) have been shown to have incipient attachment loss (AL) more frequently than systemically healthy individuals. This study investigated neutrophil activity and proinflammatory cytokines in these patients and aged-matched controls.

Methods: Elastase activity, measured with a low molecular weight substrate (S-2484), and interleukin-1beta (IL-1beta), measured with the enzyme-linked immunosorbent assay (ELISA), were analyzed in the gingival fluid of 38 patients with JIA and 29 controls.
