“…For example, a newly emerged biomarker, a soluble form of triggering receptor expressed on myeloid cells-1 (TREM-1), is associated with increased systemic inflammatory burden in patients with periodontal disease (Bostanci, Ozturk, Emingil, & Belibasakis, 2013;Nylund et al, 2017) and deregulated local immune responses in the ageing population (Ozturk, Belibasakis, Emingil, & Bostanci, 2016). Another candidate biomarker that may confer high specificity and sensitivity for the connection between oral disease and systemic conditions is matrix metalloproteinase (MMP)-8 (Rathnayake et al, 2013;Rathnayake, Buhlin, et al, 2017;Rathnayake, Gieselmann, Heikkinen, Tervahartiala, & Sorsa, 2017). There is a clear need for more accurate molecular measures that identify the systemic burden of oral infections and their impact on general health.…”
