Extended-field synchrotron microtomography for non-destructive analysis of incremental lines in human teeth cementum: example data
<h3>Abstract</h3> <p>Tooth cementum annulation (TCA) is used for determining age-at-death and stress periods based on yearly<br>deposited layers in the root cementum of human teeth. Traditionally, TCA analysis employs optical microscopy,<br>which requires cutting sections of the root and provides only sparse sampling in the third dimension. Ancient<br>teeth are often unique specimens that should not be damaged. In this imaging study, we show that extended-field<br>synchrotron radiation-based microtomography can be used to provide true micrometer resolution and full<br>coverage of the tooth for non-destructively surveying ancient teeth for incremental layers. To rapidly review the<br>root cementum layer of four teeth from an early 19th century cemetery with historical records of life events, we<br>developed a method for automatically enhancing incremental lines on virtual slices and for detecting regions with<br>strong incremental line appearances. Surveying large regions of the root cementum avoids missing high-contrast<br>incremental lines and hence improves TCA analysis as an alternative to irreversible slicing of the unique teeth.</p> <h3>Data</h3> <p>The repository contains the microtomography data from four teeth to enable reproducing Figures 6a,c,e,f in the associated publication, Tanner et al., "Extended-field synchrotron microtomography for non-destructive analysis of incremental lines in archeological human teeth cementum".

Place the .tif files called reco_????.tif in directory "dataDir1" or "dataDir2" (see last column in table) using subdirectories based on the tooth name and heightstep, e.g. "tooth4_hs04/reco/" for dataset "tooth4_hs04_reco_selZ715.tar.gz". Then set the "sampleIdx" and "hs" parameter in "dataParameterDefinitionTeeth.m" as stated in the table above. Finally run "extractCementumPatchesEnhanceIL.m" to process the data.</p> <h3>Note</h3> <p>We are grateful for beamtime access at the Synchrotron SOLEIL, ANATOMIX beamline (experiment no. 20200712).
