Effect of Porphyromonas gingivalis lipopolysaccharide on bone marrow mesenchymal stem cell osteogenesis on a titanium nanosurface.

abstract：BACKGROUND:Alanine aminopeptidase (ALAP) and dipeptidyl peptidase IV (DPPIV) are ectopeptidases that play a role in collagen degradation and are thought to be involved in the destruction of periodontal tissue. This study compared the activities of salivary ALAP and DPPIV in patients with periodontitis and periodontally...
