Comparable to annual rings present in a tree trunk, human tooth cementum contains yearly deposited incremental layers often termed incremental lines, which are generally visualized from tooth slides with optical microscopy in two dimensions. These micrometer-thin incremental lines are used to decode age-at-death and stress periods over the lifetime of an individuum. One can also visualize these layers without physical slicing by means of hard X rays because of density modulations. Within this… 


Extended-field synchrotron microtomography for non-destructive analysis of incremental lines in archeological human teeth cementum
Tooth cementum annulation (TCA) is used for determining age-at-death and stress periods based on yearly deposited lines in the root cementum of human teeth. Traditionally, TCA analysis employs
Imaging of the human tooth cementum ultrastructure of archeological teeth, using hard x-ray microtomography to determine age-at-death and stress periods
Tooth cementum annulation (TCA) is used by anthropologists to decipher age-at-death and stress periods based on yearly deposited incremental lines (ILs). The destructive aspect of the TCA method,
Microstructure of chemically modified wood using X-ray computed tomography in relation to wetting properties
Abstract X-ray computed tomography (XCT) was utilized to visualize and quantify the 2D and 3D microstructure of acetylated southern yellow pine (pine) and maple, as well as furfurylated pine samples.
Applications of computed tomography (CT) scanning technology in forest research: a timely update and review
Organic materials of woody plants are complex and show internal, structural, and morphological variations due to genetic and environmental influences. Variability can be observed in stems, branches,
Three-dimensional registration of tomography data for quantification in biomaterials science
Abstract The paper shows the benefit of registration tools in the quantitative analysis of tomography data. For this purpose three-dimensional datasets, i.e. target design in rapid prototyping, hard
Comparative hard x-ray tomography for virtual histology of zebrafish larva, human tooth cementum, and porcine nerve
Abstract. Purpose: Synchrotron radiation-based tomography yields microanatomical features in human and animal tissues without physical slicing. Recent advances in instrumentation have made

Tooth enamel and dentin are the most studied hard tissues used to explore hominin evolution, life history, diet, health, and culture. Surprisingly, cementum (the interface between the alveolar bone
Evolution and Function of Dinosaur Teeth at Ultramicrostructural Level Revealed Using Synchrotron Transmission X-ray Microscopy
It is found that the internal microstructures of saurischian teeth are very different from advanced ornithischia teeth, reflecting differences in dental developmental strategies.
