Assessment of IL-8 Levels in Saliva of Healthy and Chronic Periodontitis Individuals

Abstract

ABSTRACT Inflammation of the gums and other tissues supporting the teeth, as well as gradual loss of attachment and bone, are the results of chronic periodontitis, an infectious illness. During inflammation, a group of low molecular weight proteins called cytokines facilitate a complex interaction between inflammatory cells (such neutrophils) and other cellular components in connective tissue. The cytokine interleukin-8 (IL-8) is a potent neutrophil chemoattractant. Therefore, it is possible that IL-8 is crucial to the development of periodontitis’s pathology. Objectives: 1) To estimate concentration of IL-8 levels in healthy individuals and chronic periodontitis individuals. 2) To compare IL-8 levels in healthy and chronic periodontitis individuals Materials and Methods: Participants in this research will be recruited from among those who visit the outpatient department (OPD) at the NGH Institute of Dental Sciences and Research Centre, Belagavi, run by the Maratha Mandal. Control Group: Subjects with no clinical attachment loss (CAL) and a probing depth of 3.0 mm are considered to be periodontally healthy. Those in Group 2 (chronic periodontitis) have a chronic form of the disease, as shown by a probing pocket depth (PPD) of less than 5 mm and CAL of less than 2 mm. Unstimulated saliva sample will be collected in a 5 mL wide-mouthed sterile container by spitting method. Samples collected will be centrifuged. The supernatant is collected and stored at –80°C and then assayed for IL-8 concentration by using the standardized IL-8 ELISA kit.
