Relative closure (mean + SEM) of scratch in oral epithelial cells challenged with (a) different concentrations of heat inactivated P. gingivalis, conditioned medium from P. gingivalis, and viable P. gingivalis. Relative closure significantly different ( ) from control is marked with * (b) different concentrations of heat inactivated P. nigrescens and conditioned medium from P. nigrescens. Relative closure significantly different ( ) from control is marked with *.
