Fig. 2From: Mineralising and antibacterial effects of modified calcium phosphate treatment on human root cementumFT- IR absorption spectra of cementum: (A) CaP-F/Zn; (B) CaP-F; (C) CaP-Zn; (D) DDW. Note the spectra between 1300Â cm-1 and 500Â cm-1 showing greater resolution of PO4 absorption bands (at 1102Â cm-1, 1065Â cm-1, 1027Â cm-1) in the spectra of materials scraped from cementum surface treated with CaP-F/Zn and CaP-FBack to article page
