“…It is therefore important to emphasize that we do not assume the species-wide rate of cementum formation to be fixed (which is at the base of age estimation) but rather that a single individual's rate of cementum formation is constant. In addition, we did not find cementum thickness to be an indicator of the individual's age, especially as differences in cementum thickness are noted along the longitudinal course of the root 43 across both individuals and between teeth of the same individual (see Supplementary Table 6 and Supplementary Figures 1-9).…”

“…Its periodic deposition has been extensively noted and used for the purposes of age 31,[35][36][37][38] and season [39][40][41] at death estimation in a variety of mammals, including humans. The biological bases of the layered appearance of cementum, which has been argued to present a pair of one light and one dark band per year, is still debated 29,31,42,43 . A number of validation studies [44][45][46][47] using known-age human samples have achieved mixed results in accurately estimating age through counts of tooth cementum annulations (TCA).…”

Parturitions, menopause and other physiological stressors are recorded in dental cementum microstructure

The life history pattern of recent humans is uniquely derived in many of its aspects including an extended post-reproductive lifespan combined with short interbirth intervals. A number of theories have been proposed to explain the evolution of this unusual pattern. However most have been difficult to test due to the fragmentary nature of the hominin fossil record and the lack of methods capable of inferring such later life history events. In search of a method we tested the hypothesis that the physiologically impactful events of parturition and menopause are recorded in dental cementum microstructure. We performed histomorphological analyses of 47 teeth from 15 individuals with known life history events and were able to detect reproductive events and menopause in all females. Furthermore, we found that other stressful events such as systemic illnesses and incarceration are also detectable. Finally, through the development of a novel analytical method we were able to time all such events with high accuracy (R-squared = 0.92).

“…Teeth do not remodel, and the timing of tooth formation is well known (e.g., AlQahtani, Hector, & Liversidge, ; Dean, Beynon, Reid, & Whittaker, ). The composition of dentine from incremental structures preserves a record of diet and health conditions during the period of formation that can be related to histologically determined ages (Dean, ; Tang, Le Cabec, & Antoine, ). Serial sampling that follows the growth pattern potentially provides a time‐resolved isotopic record of dietary intake that can give detailed information about potential changes in nutrition, such as occurs during breastfeeding and weaning.…”

Tooth dentine serial sampling followed by isotope analyses allows detection of shifts in an individual's diet during the periods of tooth formation, providing information on breastfeeding, weaning, and childhood nutrition. Current sampling methods, however, do not fully capture the potential resolution of dentine increments because of the difficulties caused by the conical growth pattern, and changes in growth rate during tooth development resulting in uncertain timing. Here, we present an imaging‐assisted microsampling approach that takes the biological growth pattern of dentine into account in an effort to improve temporal resolution. We used high‐resolution light microscopy images of first molar longitudinal thin sections to generate an accurate optical reference of growth pattern and formulated a new scheme to assign collected microsamples to age. This allowed us to track dietary changes over more precisely confined and shorter time periods, providing greater detail and resolution for the breastfeeding and weaning process. We applied our method to track early life dietary history in four individuals from a small cemetery in Alsace, France, dated to the early 5th century AD (the Late Antique/Migration period). Even within this short timescale, 13C/12C and 15N/14N ratio sequences suggest variability in diets and weaning periods, and hint at early maternal mobility.

“…Given the aceramic nature of the study sites, cooking methods were probably rudimentary and probably did not help to soften food. Such heavy use of teeth is also attested by several cases of severe hypercementosis (Tang, Le Cabec, & Antoine, 2015) remarked in all the Neolithic samples, as well as some cases of cementicles (at GAS-1 and SWY-1) (Munoz, 2014). As both formations are due to chronic periodontal inflammations that can be caused by repeated mechanical stress (occlusion forces), they could result of an intense use of teeth both for alimentary and occupational purposes.…”

Transition to agriculture in South‐Eastern Arabia: Insights from oral conditions

Oral conditions from the Neolithic coastal populations denote a diet mainly composed of unprocessed and abrasive food, with high protein and low carbohydrate intakes, and frequent stress episodes. Although Hafit populations display some changes in oral pathologies, which indicate modifications in their lifestyle and a diversification of the diet, no markers of high carbohydrate intakes were observed in our samples. The impact of agriculture on oral health appears clearly only from the Umm an-Nar period, and is more intense inland than on the coast, where marine resources are still a main component of the diet.
