Myeloperoxidase as a Measure of Polymorphonuclear Leukocyte Response in Inflammatory Status Around Immediately and Delayed Loaded Dental Implants: A Randomized Controlled Clinical Trial

ABSTRACT Background: As well as gingival crevicular fluid (GCF), peri‐implant sulcus fluid (PISF) may have a potential diagnostic value for the early identification of metabolic and destructive processes. Purpose: The aim of this study was to analyze the potential impact of inflammation and loading...

Description
Summary:ABSTRACT Background: As well as gingival crevicular fluid (GCF), peri‐implant sulcus fluid (PISF) may have a potential diagnostic value for the early identification of metabolic and destructive processes. Purpose: The aim of this study was to analyze the potential impact of inflammation and loading on PISF myeloperoxidase (MPO) levels, in comparison with GCF. Materials and Methods: A total of 220 sites, dental implant (immediately [IL] or delayed loaded [DL]), and natural tooth, either healthy/noninflamed or gingivitis/inflamed, were classified. Clinical parameters were recorded, and GCF/PISF samples were obtained. GCF/PISF MPO levels were spectrophotometrically determined. Results: Clinical parameters demonstrated increases with the presence of gingival/peri‐implant inflammation. Total MPO levels were higher at inflamed tooth and implant sites compared to noninflamed/healthy sites (p
