TY - DATA T1 - Supplementary data: Assessing the Validity of a Calcifying Oral Biofilm Model as a Suitable Proxy For Dental Calculus PY - 2023/06/01 AU - Bjørn Peare Bartholdy AU - Shira Gur-Arieh UR - DO - 10.4121/466b2588-9689-4d84-a8a0-5216aa39e40b.v1 KW - oral biofilm KW - dental calculus KW - Fourier-transform infrared spectroscopy (FTIR) N2 -

FTIR analysis data on a calcifying oral biofilm model. Includes metadata, raw data and images of spectra. README.md file included in ftir_raw-data.zip.


FTIR analysis: A few ug of each sample were repeatedly ground together with KBr and pressed in a 7 mm die under two tons of pressure using a Specac mini-pellet press. Samples were analysed at the Laboratory for Sedimentary Archaeology, Haifa University. The analysis was conducted with a Thermo Nicolet is5 spectrometer in

transmission, at 4 cm<sup>-1</sup> resolution, with an average of 32 scans between wavenumbers 4000 and 400 cm<sup>-1</sup>.
