“…Nevertheless, it cannot be ruled out that an approach with a greater number of sections will achieve results that are even more accurate. An automated image analysis could also improve the accuracy of the age at death estimate [39], although it needs to be evaluated if this is also holds true for teeth from very old individuals.…”

“…Additionally, automated algorithmic software programs using Fourier analysis to count gray scale peaks in scanned images may help to reduce counting error as well, essentially eliminating the effect of intra-observer bias associated with light microscopy (Czermak et al, 2006). Fluorescent light illumination (Kvaal et al, 1996) and staining with crestyl fast violet (Naylor et al, 1985) have also been proposed as ways to enhance the contrast between incremental bands and to improve visibility.…”

“…An automated age-at-death evaluation by tooth-cementum annulations, applied to microscope images, has already been introduced in 2006 (Czermak et al, 2006). The results of the automation in comparison to manual inspection have been promising, but the representation of annual rings in OCT images is different.…”

2015. Imaging of the inner structure of cave bear teeth by novel nondestructive techniques. Palaeontologia Electronica 18.1.1T: 1-15. palaeo-electronica.org/content/2015/1058-optical-tomography-comparisons ABSTRACTThe potential of non-destructive imaging techniques, such as optical coherence tomography (OCT), X-ray micro-3D computed tomography (μ-CT) and terahertz (THz) imaging has been considered for structural and age diagnostic tasks in the field of paleontology. In particular OCT, a high-resolution, non-destructive and contactless technology for two and three dimensional (2D, 3D) imaging, was evaluated for the investigation of dental cementum microstructures, exemplified by cave bear teeth. OCT with a depth resolution in the micron range showed its ability to count the annual appositional lines consisting of cementum and thus to determine the age of the individual. As additional method also THz technology is presented which exhibits much larger penetration depths up to centimeters, but with a lower resolution, in contrast to OCT. Thus, THz imaging gives insight into the internal structure of the cave bear teeth on a larger scale. Furthermore, to complete the variety of considered non-destructive imaging techniques, μ-CT has been applied for analysis of the teeth structures, in comparison to OCT and THz imaging results. The combination of these complementary methods is well suited for the non-destructive characterization of teeth.
