About

The aim of this clinical trial is to investigate the concentrations of Lipocalin-2 and Semaphorin 3A levels in gingival crevicular fluid in subjects with different periodontal diseases. At the same time for the periodontitis group; the purpose of this study is to analyze the correlation of these proteins with clinical parameters at the first and third months after the nonsurgical periodontal treatment.

Full description

In our study, gingival crevicular fluid samples will be taken along with the measurement of all oral clinical parameters from sixty systemically healthy volunteers (20 periodontally healthy, 20 gingivitis, and 20 periodontitis). Gingival crevicular fluid samples will be taken again after the nonsurgical periodontal treatment for the periodontitis group in the first and third months. Lipocalin-2 and Semaphorin 3A levels will be determined by an enzyme-linked immunosorbent assay test (ELISA). Subsequent statistical analyses will be used to interpret protein levels among different groups and peridontitis group after the nonsurgical periodontal treatment.

Possible significant differences may illuminate the future work with Lipocalin-2 and Semaphorin 3A. Also, these glycoproteins may help to develop different diagnostic methods or treatment strategies for future periodontal treatments.
