Evaluation of the Effects of Immune Cells on Periodontal Healing — EMTA  

Periodontitis Clinical Trial

Official title:
Evaluation of the Effects of Initial Macrophage and Th17 Cell Activities on the Healing Following Periodontal Phase I Therapy

Clinical Trial Summary

Periodontitis is an inflammatory disease with an infectious character, where, as the result of the host response to a dysbiotic microflora, attachment and bone loss occur. The host response and the healing period following the treatment differs among individuals, but the reason behind is not fully understood. The macrophages and T cells play an important role in the immune response and in the pathogenesis of periodontal diseases, but their role in the healing following periodontal therapy is not known. In this study, we aim to reveal the effects of initial macrophage and T cell activities in the gingival tissue on the differences of the response to phase I periodontal treatment. 42 individuals will be included in the study. Granulation tissue samples will be collected from two separate deep pockets of each individual, initially. At the same session, full-mouth scaling and root debridement will be conducted. Saliva, subgingival biofilm and gingival crevicular fluid (GCF) samples will also be collected, initially, and at the 2nd, 6th, 12th and 24th weeks. At the same appointments, periodontal parameters will be recorded. When the clinical procedures are concluded, the samples will be sent to Turku University with dry ice. Tissue and GCF concentrations of related cytokines will be analyzed with Luminex. The density of macrophage types will be defined by immunoblot analysis of related markers. Macrophage subpopulations in tissues will be specified by proteomics. Likewise, quantities of periodontal pathogens will be evaluated with DNA isolation and next generation sequencing.
