Effect of compressive force combined with vibration on CCL2 and CCL5 in human periodontal ligament cells.

Purpose: To investigate the effect of compressive force combined with vibration on expression of CC-chemokine ligand 2 (CCL2) and 5 (CCL5) in human periodontal ligament (hPDL) cells.

Methods: Human PDL cells were cultured and assigned into four groups: control (Con), compressive force 2.0 g/cm for 24 h and 48 h (C), vibration 0.
