- Fig. 1. Comparison of calprotectin levels in PICF. PICF samples were collected from peri-implant disease sites (n = 40, diseased) and non-diseased sites (n = 34, healthy). Calprotectin amounts (a) were measured by ELISA, and its concentration (b) was normalized by the volume of PICF. Horizontal bars show the mean values of each group. *P < 0.01 : Calprotectin and cross-linked N-telopeptides of type I collagen levels in crevicular fluid from implant

NTx amounts (a) in PICF samples from peri-implant disease sites (n = 40, diseased) and non-diseased sites (n = 34, healthy) were measured by ELISA, and its concentration (b) was normalized by the volume of PICF.
