Expression of IL-22, IL-22R and IL-23 in the peri-implant soft tissues of patients with peri-implantitis

This study indicates that there is an increased expression level of IL-22 and IL-23 in patients with peri-implantitis, which may induce expression of related pro-inflammatory cytokines and may further have a crucial role in tissue repair and reconstruction in pathogenesis of peri-implantitis.
