An assay for immune complexes [ICs] in gingival crevicular fluid [GCF] could be potentially useful to ascertain the risk of periodontal disease activity at specific oral sites. This paper describes and ELISA-based method sufficiently sensitive to measure ICs in GCF samples at levels below 1 microgram/ml. Static GCF samples taken from 5 adults showed IC levels ranging from 5 to 166 micrograms/ml...

BACKGROUND Researchers have recently drawn attention to the analysis of gingival crevicular fluid (GCF) and peri-implant sulcus fluid (PISF) for the implementation of the diagnosis of periodontal and peri-implant disease. Nevertheless, the measurements of volume and biomarkers concentration can be critically biased when data collected from studies with parallel group design are compared, given ...

The aim of this study was to evaluate the potential impact of periodontal disease on quality of life in diabetics. A total of 159 dentate diabetic individuals registered at the Municipal Hospital in Itaúna, Minas Gerais, Brazil, were examined and interviewed. The clinical periodontal parameters recorded were: gingival bleeding, probing depth, and clinical attachment level. The OHIP-14 form was ...

Several biologically active substances representing the bone deposition and resorption processes are released following damage to periodontal tissue during orthodontic movement. Biomarkers by definition objective, quantifiable characteristics of biological processes. The analysis saliva/salivary fluid Gingival crevicular (GCF) may be an accepted way examine ongoing biochemical associated with t...

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...

Diabetes in rats inhibits the migration of neutrophils into the healing gingival crevice, an effect associated with impaired in vitro neutrophil chemotactic activity. We recently described the in vivo response of human and rat crevicular neutrophils to a chemotactic challenge and used this assay in the present study on streptozotocin-induced diabetic rats. Optimal concentrations of two chemotac...

Introduction: Nanobacteria have been implicated in the formation of pathogenic calcifications e.g. kidney stones, arterial plaque, calcified cardiac valves, dental pulp stone, etc. It has been hypothesized that nanobacteria may be present in dental calculus which has a similar mineralization formation process and that nanobacteria may play an efficient role in the calcification of dental calcul...

Amlodipine is a calcium channel blocker used in the management of angina and hypertension. We report 3 cases of gingival overgrowth in adult dentate patients associated with chronic usage of this drug. Gingival changes occurred within 3 months of dosage and appeared to be compounded by the patient's existing periodontal condition. In all 3 patients, there was sequestration of amlodipine in thei...
