Biological Markers For Pulpal Inflammation: A Systematic Review., Dan-Krister Rechenberg, Johnah C. Galicia, Ove A. Peters

All Dugoni School of Dentistry Faculty Articles

BACKGROUND AND OBJECTIVE: Pulpitis is mainly caused by an opportunistic infection of the pulp space with commensal oral microorganisms. Depending on the state of inflammation, different treatment regimes are currently advocated. Predictable vital pulp therapy depends on accurate determination of the pulpal status that will allow repair to occur. The role of several players of the host response in pulpitis is well documented: cytokines, proteases, inflammatory mediators, growth factors, antimicrobial peptides and others contribute to pulpal defense mechanisms; these factors may serve as biomarkers that indicate the status of the pulp. Therefore, the aim of this systematic review was to …
