FTIR and XRD characterization of heat effect on nanostructured synthetic hydroxyapatite and dental enamel. In: INTERNATIONAL CONFERENCE OF NANOPHOTONICS, 10th, July 02-05, 2017, Recife, PE. <b>Abstract...</b> p. 55-55. DisponÃvel em: http://repositorio.ipen.br/handle/123456789/27937.http://repositorio.ipen.br/handle/123456789/27937Nanometer sized HAP and dental enamel powders were evaluated regarding changes in their degree of crystallinity and composition after oven or Er,Cr:YSGG laser heating. Decrease of the Ca/P ratio to levels close to the theoretical ones for both synthetic nano-HAp and for the enamel was measured. Laser irradiation caused considerable decrease in the amount of carbonate in the materials heated to high temperatures, but without changes in crystallographic phase.55-55openAccessFTIR and XRD characterization of heat effect on nanostructured synthetic hydroxyapatite and dental enamelResumo de eventos cientÃficoshttps://orcid.org/0000-0001-7404-9606
