Hominid enamel thickness: I. The Krapina Neandertals
Dental x‐rays were taken of isolated and in situ adult molar teeth of the Krapina Neandertal (n = 63) and of recent and contemporary molars (n = 423). The radiographs were digitized at high resolution (1,024 × 1,520 × 8 bits) with a 35 mm solid state scanner. Ratios of enamel cap area to the underlying dentinal‐pulpal area were determined and comparisons were made between average ratios for the Neandertal and contemporary molars. Neandertal molar…
Dental arch shape and tooth wear variability
The rapid rate of tooth wear frequently reported among certain contemporary aboriginal populations has often been attributed to dietary form and abrasives. Several investigators have reported a close correlation between food bulk and the wear planes formed over the dental arches, i.e., steep oblique wear vs. flat horizontal planes. In this investigation we demonstrate that arch shape is an additional and a significant factor influencing the distr…
Interproximal grooving and task activity in Australia
Interproximal grooving was recorded in 85 ninetheenth century aboriginal skulls from Swanport in South Australia. One or more grooved teeth were noted in 41% of individuals, but the frequency of grooving in males was twice that in females. Distal surface grooving was noted in 93 teeht in contrast to only five instances of mesial grooving. The lesions were similar in appearance to those reported in many other population—confined primarily to the p…
Tooth wear in Australian Aboriginal populations from the river Murray valley
The study of tooth wear among prehistoric and recent populations has frequently been concerned with the rate and pattern of wear over the dental arches. In this report we considered the question of tooth wear variation among collections of Australian Aboriginal crania recovered from several sites along the Murray River in Southeastern Australia. These crania represent the remains of relatively recent populations from about 2,000 years ago until t…
The effect of geochemical factors on prevalences of dental diseases for prehistoric inhabitants of the state of Missouri
In previous epidemiological studies, it has been suggested that geochemical factors besides fluoride may affect the prevalences of dental diseases. Our objective in this study was to determine whether the prevalences of periodontal diseases, coronal caries, and root caries for prehistoric inhabitants vary between geochemical regions of the state of Missouri. Burial sites were located on unique maps that depict geochemical variation among regions …
Measurements of tooth wear among Australian aborigines: II. Intrapopulational variation in patterns of dental attrition
The possible implications of variations in dental attrition patterns have necessitated a detailed assessment of the types, ranges, and causes of tooth wear. Here we employ measurements of postcanine occlusal wear facets from a sample population of extant Australian aborigines. A principal components analysis was applied as a tool in determining common types of attritional patterns. It was concluded that the range of intrapopulational variation in…
Observations of dental diseases among prehistoric populations of Hungary
The incidence of dental disease among people in developing countries today raises questions about the variation in the oral health of prehistoric populations. Considering these questions, we offer observations describing several types of dental disease which occurred among certain prehistoric populations of Hungary. The dental remains of 162 individuals recovered from seven sites of the Neolithic, Copper, and Bronze Age periods were examined for …
The Incidence of Enamel Hypoplasia among the Krapina Neandertals
Developmental defects of teeth often appear as a record of metabolic disturbances during growth. One defect in particular, enamel hypoplasia, has been described among recent prehistoric human populations, but few analyses have been made of fossil hominids. This study describes the enamel quality of the dental remains of the Krapina Neandertals. Of the 18 individuals represented by dental arch fragments, 13 showed evidence of one or more teeth wit…
Measurements of tooth wear among Australian Aborigines: I. Serial loss of the enamel crown
The dental casts made from Aboriginal children during the course of a longitudinal growth study in Central Australia provided material for analyzing tooth wear under known environmental conditions. The wear facets produced on the occlusal surfaces were clearly preserved on the dental stone casts and recorded the progress of enamel attrition from ages 6 to 18. These casts were photographed and traced by electronic planimetric methods that automati…

Experimental stress analysis of topographic diversity in early hominid gnathic morphology
Reconstructing the biomechanics of early hominid mastication is a key element in most models of hominid differentiation. Traditionally, ostelogical features marking muscle attachment surfaces have served as a reference system from which the vector geometry of the masticatory force system and resultant force distributions could be predicted. To augment traditional morphological and computational approaches, we developed a simulation system capable…
Functional implications of primate enamel thickness
Recent evolutionary interpretations of Hominoidea have postulated functional relationships between tooth form, diet and masticatory biomechanics. A major consideration is the durability of the tooth under certain dietary conditions. Teeth with low cusps and thicker enamel are able to withstand heavy mastication of abrasive food bolus for a longer period. When comparisons are made between species of higher primates the variables of tooth size, cus…

Mineral metabolism and microstructural defects in primate teeth
There are numerous structural defects that occur in primate teeth due to variable calcification during certain growth stages. These interruptions are usually areas of hypomineralization in enamel and dentin which are referred to as Striae of Retzius and Hunter Shreger bands in the enamel or Incremental Lines of von Ebner and Contour Lines of Owen in the case of the dentin. The frequency of occurrence of these variations in mineralization can be r…

Tooth Wear and Culture: A Survey of Tooth Functions Among Some Prehistoric Populations [and Comments and Reply]
Studies of hominid fossils have frequently reported that one of their outstanding characteristics is their heavily worn teeth. Many skeletal remains of modern man also show this condition of dental attrition, which is probably related to certain cultural activities. The varieties of foods consumed by primitive man and the specialized tool functions of the teeth have left significant marks in the form of worn occlusal surfaces over the dental arch…
Human tooth wear, tooth function and cultural variability
Among primitive peoples dental attrition appears to be a natural phenomenon. Often the degrees and kinds of tooth wear vary from population to population. This variability is possibly related to certain material aspects of culture such as diet, food preparation techniques and tool usage. In order to learn more about these relationships, extensive cross cultural comparisons must be made. This paper reports on a study of dental attrition among skel…
Sex, Age, and Tooth Position as Factors in the Production of Tooth Wear
In recent studies of heavily worn teeth of California Indian skeletal remains, considerable difference was seen in types and degree of wear. This variation in dental attrition was related to factors of sex, age, tooth position, and, in some cases, dental caries. The relative importance of each of these variables was considered.The sex of the individual was found to be a major factor in tooth wear and a higher degree of attrition was found among f…

Experimental studies in human tooth wear: Ii
Studies of human tooth wear have been carried on for the past two years using a machine designed to approximate human chewing motions. During this time wear patterns that resemble those frequently found on the teeth of various American Indian skulls have been produced on casts of the definition. Noticeably among these patterns produced are examples of wear on the front end of the dental arches that result in an edge to edge bite. This type of wea…
