Relationship between serum tumor necrosis factor receptor-2 concentration and periodontal destruction in patients with type 2 diabetes: Cross-sectional study.

Introduction: The role of tumor necrosis factor-α (TNFα) is well documented in pathogenesis of chronic periodontitis (CP) and type 2 diabetes (T2D). Considering short half-life of TNFα, tumor necrosis factor receptor-2 (TNFR2) is used as prosperous surrogate marker of TNFα activity.

Objective: The aim was to detect TNFR2 serum concentration and correlate it with periodontal destruction in patients with diagnosed T2D and nondiabetics.

MMP-9 -1562 C>T (rs3918242) promoter polymorphism as a susceptibility factor for multiple gingival recessions.

The objective of this pilot study was to investigate the potential role of -1562 C>T single nucleotide polymorphism (SNP) in the promoter region of the matrix metalloproteinase-9 (MMP-9) gene as a risk modulator in the development of multiple gingival recessions (MGRs) in young adults in the Serbian population. The study sample comprised 161 systemically healthy people: 60 with MGRs and 101 controls with healthy periodontal tissues. Genotyping was done using polymerase chain reaction/restriction fragment length polymorphism approach on DNA obtained from buccal swabs.

Clinical application of autologous fibroblast cell culture in gingival recession treatment.

Background And Objective: Gingival recession is defined as soft and hard tissue displacement resulting in root surface exposure. The optimal outcome of gingival recession treatment is complete, predictable and long-lasting root coverage with a significant level of tissue regeneration. Tissue engineering, which applies active regeneration principles, presents the contemporary treatment approach in the restitution and regeneration of lost tissues.

Receptor activator of nuclear factor kappa B (RANK) as a determinant of peri-implantitis.

Background/aim: Peri-implantitis presents inflammatory process that affects soft and hard supporting tissues of osseointegrated implant based on inflammatory osteoclastogenesis. The aim of this study was to investigate whether receptor activator of nuclear factor kappa B (RANK) concentrations in peri-implant crevicular fluid could be associated with clinical parameters that reflect inflammatory nature of peri-implantitis.

Methods: The study included 67 patients, 22 with diagnosed peri-implantitis, 22 persons with healthy peri-implant tissues and 23 patients with periodontitis.

Impact of interleukin 1 gene polymorphism and smoking on long-term stability following gingival recession treatment.

Risk factors such as smoking, genetic factors, and tissue biotype play an important role in the etiology, predictability, and long-term stability of gingival recession treatment. This study was designed to evaluate the influence of interleukin 1 (IL-1) polymorphism and smoking on the stability of gingival recession treatment after 1 and 3 years. All patients (n = 55) were treated for type I and II recession defects using a connective tissue graft.
