Alizarin red staining denoting mineralization at 14 days post seeding. (a) Alizarin red staining images and (b) quantified data of alizarin red staining from colour thresholding software for PDL cells treated with HA_ncl or HA_cl (** denotes significantly higher than all other treatment modalities, p < 0.05). It was found that both HA_ncl and HA_cl treatment significantly decreased alizarin red staining
