  BACKGROUND: Matrix metalloproteinase-1(MMP-1)plays an important role during the destruction of periodontal tissue.Although multiple studies had focused on the association between MMP-1 g.-1607dupG and periodontitis susceptibility,the results remained inconclusive.The purpose of this meta-analysis was to explore its role in the development of periodontitis.
