Abstract:

In 2011, Brooklyn-based artist Heather Hart introduced her interactive installation The Oracle of Epicure: Tooth for Tooth. For this, she transcribed a selection of recipes onto note cards and adorned each with an original drawing. Filed in a recipe box and set on top of a desk, viewers were invited to take one card in exchange for a recipe of their own that was to be written from memory on the spot. This article gives the particulars of Heather's installation with special attention given to the source of her recipes: Harry H. Hart's Favorite Recipes of Williams College, with Training Table Records, Notes and Menus (1951). Harry Hart, a chef at Williams College from 1917 to 1954, was Heather's great grandfather. Harry Hart, Jr., Heather's grandfather, was also a chef at Williams College from 1938 until circa 1959. By way of Tooth for Tooth, the Hart family's rich culinary history is conveyed for the first time here.

Abstract:

Abstract The standard tooth width ratio tables currently do not provide an overall indication of the final interdigitation of teeth. To provide a comprehensive analysis of inter-arch tooth width discrepancy, this study has developed a combination of cumulative percentage tooth width ratios and a method to visually determine the harmony betweeu maxillary and mandibular tooth widths. Mesiodistal tooth widths from the first permanent molar to the corresponding first permanent molar were measured from 60 sets of pretreatment study models which were selected consecutively. Cumulative percentage ratios relating mandibular teeth to maxillary teeth were calculated utilising the mesiodistal tooth width measurements. The 13 mean cumulative percentage ratios developed in this study were plotted on graph paper showing plus and minus two standard deviations from the mean. These ratios provide a standard from which cumulative percentage ratios obtained from any new case may be compared graphically. Deviations from the mean cnmulative percentage ratios are immccliately recognised. No simple graphical method of assessment on the final intercligitation of anterior and posterior teeth has previonsly been dcvisecl. The graphical analysis of toolh width discrepancy is invalnahle as an aicl in localising any toolh width discrepancy and ensnring that incompatihle maxillary-to-manclibnlar tooth wid ths are recognised prior to orthodontic treatment.

Abstract:

Tooth enamel/cementum junction represents an important area in the tooth regarding the incorporation of mineral tissues that bear high pressure forces. The level of the junction is important in measuring the depth of the periodontal sac and the level of attachment. On the tooth enamel/cementum junction, the tooth enamel, cementum and dentin connect in an unregulated curve. We will present, in this article, the morphology of the toot enamel/ cementum junction, the identification methods and it´s importance in clinical practice.

Abstract:

Background Saber-toothed mammals, now all extinct, were cats or “cat-like” forms with enlarged, blade-like upper canines, proposed as specialists in taking large prey. During the last 66 Ma, the saber-tooth ecomorph has evolved convergently at least in five different mammalian lineages across both marsupials and placentals. Indeed, Thylacosmilus atrox, the so-called “marsupial saber-tooth,” is often considered as a classic example of convergence with placental saber-tooth cats such as Smilodon fatalis. However, despite its superficial similarity to saber-toothed placentals, T. atrox lacks many of the critical anatomical features related to their inferred predatory behavior—that of employing their enlarged canines in a killing head strike. Methods Here we follow a multi-proxy approach using canonical correspondence analysis of discrete traits, biomechanical models of skull function using Finite Element Analysis, and 3D dental microwear texture analysis of upper and lower postcanine teeth, to investigate the degree of evolutionary convergence between T. atrox and placental saber-tooths, including S. fatalis. Results Correspondence analysis shows that the craniodental features of T. atrox are divergent from those of placental saber-tooths. Biomechanical analyses indicate a superior ability of T. atrox to placental saber-tooths in pulling back with the canines, with the unique lateral ridge of the canines adding strength to this function. The dental microwear of T. atrox indicates a soft diet, resembling that of the meat-specializing cheetah, but its blunted gross dental wear is not indicative of shearing meat. Conclusions Our results indicate that despite its impressive canines, the “marsupial saber-tooth” was not the ecological analogue of placental saber-tooths, and likely did not use its canines to dispatch its prey. This oft-cited example of convergence requires reconsideration, and T. atrox may have had a unique type of ecology among mammals.

Abstract:

The acquisition of elongated, sabre-like canines in multiple vertebrate clades during the last 265 Myr represents a remarkable example for convergent evolution. Due to striking superficial similarities in the cranial skeleton, the same or similar skull and jaw functions have been inferred for sabre-toothed species and interpreted as an adaptation to subdue large-bodied prey. However, although some sabre-tooth lineages have been classified into different ecomorphs (dirk-tooths and scimitar-tooths) the functional diversity within and between groups and the evolutionary paths leading to these specializations are unknown. Here, we use a suite of biomechanical simulations to analyse key functional parameters (mandibular gape angle, bending strength, bite force) to compare the functional performance of different groups and to quantify evolutionary rates across sabre-tooth vertebrates. Our results demonstrate a remarkably high functional diversity between sabre-tooth lineages and that different cranial function and prey killing strategies evolved within clades. Moreover, different biomechanical adaptations in coexisting sabre-tooth species further suggest that this functional diversity was at least partially driven by niche partitioning.

Abstract:

Fear of the dentist can be a very serious issue for many children and adolescents. According to academic researches into Dental Fear and Anxiety, some young people hate dentist visits so much that they often refuse to co-operate, or worse - they don’t even go to the dentist. Scientists at Princeton and Tufts have been working a thin tooth sensor that may limit the amount of times we will need to get our teeth checked. The sensor will alert you when it detects any bacteria that could cause cavities, plaque buildup, or any other infections. The scientists say that the new sensor can recognize human oral activities, such as chewing, drinking, speaking and coughing. It also can help to better understand people’s habits and identify potential health problems, such as if a person is smoking or drinking too much. The sensor is so small that it can either fit inside an artificial tooth or straddle a real one.

Abstract:

The tooth is closely related to the periodontium in which it sits, with a soft tissue interface forming between the alveolar bone and hard tissues of the tooth. This is known as the tooth-bone interface (TBI). In functional teeth, the TBI houses the periodontal ligament, while during development the TBI creates a space into which the tooth can grow. This project aims to provide an understanding of how the formation of the tooth and bone are coordinated during development and characterise the underlying factors and mechanisms that prevent bone formation and invasion at the interface between the tooth and bone. Using murine mandibular first molar (M1) TRAP stained histological sections, osteoclasts were found to be closely associated with the border of the developing bone, lining the TBI, but not within the TBI itself. Slice culture was used to follow tooth development in explant culture as it provided an excellent opportunity for manipulation and lineage tracing. DiI labelling experiments showed the contribution of two sources of cells in the formation of alveolar bone namely, dental follicle cells from around the tooth and, bone cells from the margins of the dentary. Isolation experiments were used to investigate the impact of the tooth on the bone and bone on the tooth. Isolation of E14.5 mandibular first molar (M1) tooth germ from the surrounding mesenchyme and alveolar bone resulted in tooth germ expansion while removing the tooth epithelium did not change the normal layout of osteoclasts at E14.5. The effect of manipulating the BMP signalling pathway on the differentiation of cells in the TBI during tooth development was studied. A local reduction in the TBI was observed next to the BMP-4 beads whereas a local widening in the TBI was observed when Noggin beads were implanted. The effect of manipulating the RANK-RANKL signalling pathway was investigated next. In situ hybridisation revealed the presence of OPG, RANK, and RANKL in the alveolar bone but OPG and RANKL only in the dental epithelium. Addition of exogenous RANKL to tooth explants in culture resulted in a statistically significant increase in osteoclast numbers and a widening of the TBI. On the other hand, the results obtained after exogenous OPG addition were regarded as inconsistent due to high variability. However, correlation of the difference in bone growth within a cultured tooth germ with the presence of osteoclasts showed absence of osteoclasts in areas of bone encroachment and the opposite, presence of osteoclasts, in areas devoid of bone. The TBI then was analysed in c-Fos mutants, a knockout mouse known to have a defect in osteoclastogenesis, resulting in lack of osteoclast production. Genotyping showed that the c-Fos mutant embryos were displaying the expected Mendelian ratio, but almost all the homozygotes died after birth, and the heterozygotes viability was found to be compromised. Micro-CT analysis of a 3 week old c-Fos homozygote showed a strong osteopetrotic phenotype. Defects in the midline diastema, tooth impaction, and lack of roots were also observed. The TBI showed signs of bone invasion, encroaching on the M1. TRAP assay revealed few positive-stained mononucleated cells, which were probably macrophages. In conclusion this thesis demonstrates that the formation and maintenance of the TBI appears to be a finely regulated two-pronged process with control of osteoclast differentiation used to remove the bone (osteoclastogenesis), combined with inhibition of bone induction (osteogenesis). Together these two processes create a bone-free zone around the tooth. By changing either of these processes the TBI is disrupted and tooth development is altered.

Full text

Abstract:

In the mid 1970s American paediatric dentists started publishing claims that breast feeding an infant on demand and/or during the night was as dangerous to the infant's dental health, in terms of the production of caries, as the previously established dangers of Baby Bottle Tooth Decay. It was argued by some dentists that this danger increased if the infant was breast fed for an extended period of time. Such claims have gained support from many dentists, and their professional bodies, into the twenty-first century. This thesis examines the historical, social, commercial and cultural influences that supported the development of such assertions. It analyses the ways in which expert reinforcement was gained, and scrutinises the scientific controversy as publicly fought in professional journals and other outlets. The thesis also examines the growing status of the dental profession, especially in connection with its claim to specialised scientific and medical knowledge in the production of dental caries. Further, consideration is given to the medicalisation of breast feeding and the associated commercial infant feeding dispute. The thesis attempts to redress the current lack of theoretical analysis of the construction of dental knowledge. To date there has been minimal academic contribution to the history of dentistry; however, the absence of extensive analysis has been advantageous in enabling an original approach to the material.

Abstract:

This thesis describes work investigating the mechanisms that result in the eruption of teeth out of the jaws into the mouth, as well as the post-eruptive continuous emergence of teeth once they have entered the mouth. First Chapter summarizes relevant literature on the formation and movement of teeth, and identifies difficulties with the current widely accepted concept of an 'eruptive force' driving teeth into the mouth. Chapter 2 outlines relevant biomechanical principles for Finite Element Analysis (FEA) and by FEA explores the possible role of functional stress in driving continuous post-eruptive emergence of teeth. Data in Chapter 3 support a new hypothesis for tooth eruption, in which the follicular soft tissues detect bite-force-induced bone-strain, and direct bone remodeling at the inner surface of the surrounding bony crypt, with the effect of enabling tooth eruption into the mouth. Consequent to work described in Chapter 3, was a need to further characterize mechanosensor activity in dental follicle cells, to that end, Chapter 4 outlines the relevant literature and describes experimental work examining the possible mechanosensor response of cultured dental follicle cells isolated from tissue obtained from extracted wisdom teeth.

Full text

Abstract:

Sauropod tooth morphologies and tooth replacement patterns bear important information on feeding habits and sauropod evolution. Euhelopus zdanskyi is an Early Cretaceous neosauropod, and belongs to the group Euhelopodidae, which is the sister group of Titanosauria. Euhelopus is a key taxon in the evolution of sauropod teeth, because it displays a very conservative tooth morphology compared to that seen in Titanosauria, despite being a close relative. The teeth of Euhelopus resemble those of Camarasaurus, as well as many basal sauropods that are not closely related to Euhelopus. The teeth of Euhelopus are spoon-shaped, and they have approximately two replacement teeth for each functional tooth. Their robust morphology and low number of replacement teeth suggest that they were worn down a lot more slowly than the pencil-shaped teeth of Titanosauria and Diplodocoidea. Diplodocoids, whose teeth have been studied widely, especially show very rapid tooth replacement rates, and the tooth morphology of titanosaurs suggests that they might have had similar replacement rates. On the contrary, Euhelopus was likely to have replacement rates similar to the relatively low rates of Camarasaurus, whose tooth battery is much like that of Euhelopus. Furthermore, some euhelopodids are known to have had pencil-shaped teeth, which indicates that there was a strong evolutionary pressure towards the development of narrow teeth during the Late Cretaceous. This pressure may have been caused by a change in vegetation or may merely represent somphospondylans occupying the niches vacated by the diplodocoids, which appear to have gone extinct before the end of the Cretaceous. This study uses 3D modelling for inspecting tooth replacement of Euhelopus and evolution of sauropod teeth.

Full text

Abstract:

The effects of two seal design parameters, namely blade (tooth) thickness and blade profile, on labyrinth seal leakage, as well as the effect of operating a seal in an off-center position, were examined through a series of non-rotating tests. Two reconfigurable seal designs were used, which enabled testing of two- four-, and six-bladed see-through labyrinth seals with different geometries using the same sets of seal blades. Leakage and cavity pressure measurements were made on each of twenty-three seal configurations with a four inch (101.6 mm) diameter journal. Tests were carried out with air as the working fluid at supply pressures of up to 100 psi-a (6.89 bar-a). Experimental results showed that doubling the thickness of the labyrinth blades significantly influenced leakage, reducing the flow-rate through the seals by up to 20%. Tests to determine the effect of blade-tip profile produced more equivocal results, with the results of experiments using each of the two test seal designs contradicting each other. Tests on one set of hardware indicated that beveling blades on the downstream side was most effective in limiting leakage whereas tests on newer hardware with tighter clearances indicated that seals with flat-tipped blades were superior. The test results illustrated that both blade profile and blade thickness could be manipulated so as to reduce seal leakage. However, an examination of the effects of both factors together indicated that the influence of one of these parameters can, to some extent, negate the influence of the other (especially in cases with tighter clearances). Lastly, for all configurations tested, results showed that leakage through a seal increases with increased eccentricity and that this phenomenon was considerably more pronounced at lower supply pressures.

Abstract:

It is very difficult, if not impossible, to estimate the impact resistance of gear teeth from standard impact test data. This is because of the in-homogenous nature of most gear teeth, with a high-Carbon case and a low-Carbon core, and its complex geometry. While gears are subject to impact loading in “real life” and current research efforts are significantly focused on developing alternate materials for gears, in a variety of applications, a need to characterize the impact resistance of a gear tooth under varying strain rates has consequently arisen. In order to meet this need an existing drop tower has been modified and instrumented to test gear teeth under varying strain rates to induce various modes of fracture. This paper describes the analytical model developed to represent the drop tower and the gear holding fixture, which was utilized to evaluate various design alternatives to design a system where strain rates could be varied. Based on the results of the model, a system was implemented and a preliminary set of impact tests conducted. While some dynamic problems were encountered, these tests show that the system is performing largely as required. The source of the dynamic problems encountered was also examined and changes to the system to overcome these problems are planned. Data obtained in the impact tests conducted will also be presented to demonstrate the capability of the system.
