Since ingredients of peri-implant sulcus fluid (PISF) may be related to the bony structure surrounding dental implants, analyze of specific markers related to bone resorption in PISF seems to be suitable for long term monitoring of peri-implant health. It is suggested that analysis of PISF may serve for detection of inflammation. The aim of this study is to analyze PISF interleukin-1 beta (IL-1β), IL-10, osteoprotegerin (OPG), receptor activator of nuclear factor-kappa B ligand (RANKL) levels to determine whether the diagnostic value of PISF can be used to evaluate early changes around implants.

A total of 47 dental implants either healthy/non-inflamed (n=20) (Group I), or gingivitis/inflamed (n=27) (Group II), were classified. Peri-implant status has been evaluated by clinical evaluation (plaque index, gingival index, probing depth and gingival bleeding time index) were recorded …
