SEM analysis of tooth enamel.
SEM analysis contains researches of tooth enamel surfaces of two populations. First group of samples is tooth enamel of prehistorically ancestor from Vucedol and the second group of samples is enamel of modern Croatian citizen. Even on small number of human teeth samples from cooperage site of Vucedol (3,000 BC) and today's Croatian people, we can conclude about chewing biometry of prehistorica...
متن کاملSusceptibility of enamel to initial erosion in relation to tooth type, tooth surface and enamel depth.
This study aimed at assessing the susceptibility of different tooth types (molar/premolar), surfaces (buccal/lingual) and enamel depths (100, 200, 400 and 600 μm) to initial erosion measured by surface microhardness loss (ΔSMH) and calcium (Ca) release. Twenty molars and 20 premolars were divided into experimental and control groups, cut into lingual/ buccal halves, and ground/polished, removin...
متن کاملSex determination of human remains from peptides in tooth enamel
The assignment of biological sex to archaeological human skeletons is a fundamental requirement for the reconstruction of the human past. It is conventionally and routinely performed on adults using metric analysis and morphological traits arising from postpubertal sexual dimorphism. A maximum accuracy of ∼95% is possible if both the cranium and os coxae are present and intact, but this is seld...
متن کاملUnlocking evidence of early diet from tooth enamel.
Recent developments in microspatial analysis of enamel chemistry provide the resolution needed to reconstruct detailed chronological records of an individual's early life history. Evidence of nutritional history, residential mobility, and exposure to heavy metals can potentially be retrieved from archaeological and even fossil teeth. Understanding the pattern and timing of incorporation of each...
متن کاملSpots on tooth enamel: what’s new?
Enamel is the most visible tissue of the tooth. It gives the tooth its whiteness, its brilliance and is the main focus of our attention from an esthetic point of view. Unfortunately, it is not uncommon to see alterations in this enamel, whether they are simple localized discolored spots, or more extensive loss of tooth substance. The etiologies, then, are multiple: toxicity during the mineraliz...
