CONTEXT Periodontitis is the most common lytic disease of bone and is recognized as a common complication of diabetes. Lipid peroxidation (LPO) is increased in diabetes and may be related to modulation of the inflammatory response. LPO levels in patients with diabetes and periodontal disease have not been evaluated. OBJECTIVE The aim of this study was to evaluate the levels of LPO and its cor...

background: the possibility of impaired antioxidant status and so increased oxidative damage in periodontal disease is being conjectured. the present randomized controlled study was carried out with the objective of analyzing the activity of superoxide dismutase enzyme and thiol antioxidants in gingival crevicular fluid (gcf) and saliva as indicators of response to periodontal therapy. material...

PURPOSE To evaluate and compare peri-implant health, marginal bone loss and success of immediate and delayed implant placement for rehabilitation with full-arch fixed prostheses. MATERIAL AND METHODS The present study was a prospective, randomized, single-blind, clinical preliminary trial. Patients were randomized into two treatment groups. In Group A implants were placed immediately post-ext...

OBJECTIVE To determine the oral status, salivary flow rate, Candida carriage in saliva, and prevalence of Candida albicans colonization in several areas of the mouth in patients with primary and secondary Sjögren's syndrome as opposed to those of healthy subjects. STUDY DESIGN Thirty-seven patients with Sjögren's syndrome (SS), [14 patients with primary SS (SS-1) and 23 patients with secondar...

BACKGROUND Matrix metalloproteinases (MMPs) and cytokines play a role of extracellular matrix degradation and remodelling, and are significantly involved in the course of periodontal disease. OBJECTIVES The purpose of this study was to evaluate the adjunctive effect of administering an oxicam non-steroidal anti-inflammatory drug (NSAID), tenoxicam, during non-surgical (phase 1) periodontal tr...

INTRODUCTION Crown materials used in fixed prosthodontics come into close and prolonged contact with the gingiva. OBJECTIVE The purpose of this study was to evaluate the effect of different crown materials on the interleukin-one beta (IL-1β) content of the gingival crevicular fluid and to study which crown material causes the highest inflammation on the marginal gingiva on a biochemical basis...

Background and Aim: Increased levels of receptor activator of nuclear factor kappa-B ligand (RANKL) and RANKL/OPG (osteoprotegerin) ratio in untreated periodontitis have been presented. However, current knowledge of periodontal treatment on osteoimmunological results is scarce. This study, aims to determine the RANKL, OPG, interleukin-1 beta (β), interleukin-10 levels in gingival crevicular flu...

AIM Inflammatory periodontal disease is widespread in dogs. This study evaluated site-specific changes in the canine gingival crevicular fluid (GCF) proteome during longitudinal progression from very mild gingivitis to mild periodontitis. Periodontitis diagnosis in dogs requires general anaesthesia with associated risks and costs; our ultimate aim was to develop a periodontitis diagnostic for a...

Chlamydia pneumoniae has been associated to atherosclerotic cardiovascular diseases. The aim of our study was to characterize, for the first time, a C. pneumoniae strain isolated from the gingival crevicular fluid of a patient with chronic periodontitis, described as a risk factor for cardiovascular diseases. C. pneumoniae isolate was characterized and compared to the respiratory AR-39 strain b...

AIM The aim of this study was to assess the levels and diagnostic accuracy of a set of potential biomarkers of periodontal tissue metabolism in gingival crevicular fluid (GCF) from patients with chronic periodontitis (CP) and asymptomatic apical periodontitis ( AAP). MATERIALS AND METHODS Thirty one GCF samples from 11 CP patients, 44 GCF samples from 38 AAP patients and 31 GCF samples from 1...
