ATR-FTIR and Raman Spectroscopy of Peri-Implant Crevicular Fluid in Peri-Implantitis

Sponsor: Necmettin Erbakan University

Summary

Peri-implantitis is an inflammatory condition affecting the tissues surrounding dental implants and may lead to supporting bone loss. Current diagnosis is mainly based on clinical and radiographic findings. However, these methods may not fully reflect the biological changes occurring around implants. The purpose of this observational study is to evaluate whether peri-implant crevicular fluid (PICF), a biological fluid collected from around dental implants, shows different molecular characteristics in peri-implant health and peri-implantitis. Adults who have at least one healthy dental implant and one implant with peri-implantitis will be included. For each participant, PICF samples will be collected from one healthy implant and one peri-implantitis implant. The samples will be analyzed using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy and Raman spectroscopy. These techniques provide molecular information about biological samples without requiring additional invasive procedures. The study will compare the spectral profiles obtained from healthy and peri-implantitis sites and evaluate whether these profiles can distinguish peri-implant health from peri-implantitis. Relationships between spectral findings and clinical factors, including probing depth, bleeding on probing, suppuration, radiographic bone loss, smoking status, and diabetes status, will also be explored.
