“…The occlusal relationship between upper and lower tooth rows and crown morphology (whether worn or unworn) are the primary agents responsible for delimiting where wear facets can be produced (Every, 1972;Schneck, 1981, 1982;Kaidonis et al, 1993;Hillson, 2003;Kaidonis, 2008). Biomechanical constraints such as masticatory muscles, jaw geometry, tooth shape, and crown size may also affect the position of wear facets.…”

The position of dental wear facets depends on crown morphology, antagonistic relation, and occlusal movements. The correspondence between specific directions of movements and the position of wear facets cannot be easily evaluated in vivo and has never been tested experimentally. An experimental analysis was carried out to provide evidence that explicit occlusal movements are responsible for the spatial position of wears facets. Unworn dental stone replicas of modern human prosthetic molar were mounted in a physical dental articulator, and the upper dental arch was ground against the lowers to create a wear facet pattern. The relief guided movements were constrained sequentially by means of three different condyle box setups: (1) experienced-based mean values for sagittal condyle inclination, lateroretrusion, Benett angle, and transversal condyle inclination were used; (2) pure retrusion and immediate side shift movements were added; (3) retrusion and immediate side shift were increased. Finally, the upper and lower first molars were surface scanned and macrowear facets were quantified in four wear stages. The results show that a wear facet pattern was created similar to what is seen on human molars in vivo occlusion. Some facets only developed if specific directions of movement were carried out. Therefore, we posit that an analysis of wear facet patterns is useful in recreating the individual occlusal movements. This information can be used not only to guide reproducible functional reconstructions of crown relief and dental arches but also to deduce jaw movements when, for example, isolated primate teeth are discovered in paleontological contexts.

“…Schwartz and Dean (2005) hypothesized that the size difference could be the result of a greater amount of dentin tissue present in male teeth. But other studies found very little sexual dimorphism in tooth size (Garn et al, 1964;Hillson, 1996;Mizoguchi, 1988). Harris (2003) reported that sexual variance accounted only for 1.2% of the total variation among studied groups.…”

“…These features have been used extensively to infer dietary habits, subsistence strategies, food preparation techniques, and cultural practices among ancient human populations (Deter, 2009;Hillson, 1996;Rose and Ungar, 1998;Smith, 1984). The abrasive properties of food have a direct impact on enamel loss and on the rates of tooth wear during an individual's life span (Kieser et al, 2001); that is, tough, fibrous, and abrasive diets require high biting forces during chewing and cause severe dental wear (Kiliaridis et al, 1995).…”

AbstractApart from reflecting modern human dental variation, differences in dental size among populations provide a means for studying continuous evolutionary processes and their mechanisms. Dental wear, on the other hand, has been widely used to infer dietary adaptations and variability among or within diverse ancient human populations. Few such studies have focused on modern foragers and farmers, however, and diverse methods have been used. This research aimed to apply a single, standardized, and systematic quantitative procedure to measure dental size and dentin exposure in order to analyze differences among several hunter-gatherer and agricultural populations from various environments and geographic origins. In particular, we focused on sexual dimorphism and intergroup differences in the upper and lower first molars. Results indicated no sexual dimorphism in molar size and wear within the studied populations. Despite the great ethnographic variation in subsistence strategies among these populations, our findings suggest that differences in sexual division of labor do not affect dietary wear patterns.

“…In addition, dentine incorporates higher levels of lead, and is likely to represent a longer period of exposure than enamel. 30,31 We decided to focus on dentine lead levels as a marker of long-term lead exposure in this study, although comparisons with pre and post-natal enamel lead levels are made where appropriate.…”

Lead is an environmental contaminant causing irreversible health effects in children. We used dentine lead levels as a measure of early life lead exposure and explored determinants of lead exposure in children living in Newcastle upon Tyne, a historically industrialised UK city, in a cohort born since legislation was introduced to remove lead from petrol, paint and water pipes. The 'Tooth Fairy study' cohort comprised 69 children aged 5-8 years. We collected upper deciduous incisors from children and questionnaire data from their parents in 2005. We measured lead levels in pre and post-natal enamel and dentine using Laser Ablation Inductively Coupled Plasma Mass Spectrometry, and assessed associations between dentine lead levels and residential, dietary, lifestyle and socio-economic characteristics. Dentine lead levels were low (mean 0.26µg/g, range 0.06-0.77), however we observed considerable variability in dentine lead levels within and between children suggestive of differing exposure levels and/or exposure sources across this population. Variables earlier documented to be associated with childhood lead levels were not found to be significant determinants of dentine lead levels in this study. Exposure pathways should continue to be investigated to enable targeted interventions and prevention of lead-induced health impacts in vulnerable populations.
