Homologies of the Anterior Teeth in Lndriidae and a Functional Basis for Dental Reduction in Primates
Homologies of the Anterior Teeth in lndriidae and a Functional Basis for Dental Reduction in Primates PHILIP D. GINGERICH Museum of Paleontology, The University of Michigan, Ann Arbor, Michigan 48109 KEY WORDS Dental reduction a Lemuriform primates . Indriidae . Dental homologies - Dental scraper . Deciduous dentition - Avahi ABSTRACT In a recent paper Schwartz ('74) proposes revised homologies of the deciduous and permanent teeth in living lemuriform primates of the family Indriidae. However, new evidence provided by the deciduous dentition of Avahi suggests that the traditional interpretations are correct, specifically: (1) the lat- eral teeth in the dental scraper of Indriidae are homologous with the incisors of Lemuridae and Lorisidae, not the canines; (2) the dental formula for the lower deciduous teeth of indriids is 2.1.3; (3) the dental formula for the lower perma- nent teeth of indriids is 2.0.2.3;and (4)decrease in number of incisors during pri- mate evolution was usually in the sequence 13, then 12, then 11. It appears that dental reduction during primate evolution occurred at the ends of integrated in- cisor and cheek tooth units to minimize disruption of their functional integrity.

Oral Structure, Dental Anatomy, Eruption, Periodontium and Oral
Oral Structures and Types of teeth By: Ms. Zain Malkawi, MSDH Introduction • Oral structures are essential in reflecting local and systemic health • Oral anatomy: a fundamental of dental sciences on which the oral health care provider is based. • Oral anatomy used to assess the relationship of teeth, both within and between the arches The color and morphology of the structures may vary with genetic patterns and age. One Quadrant at the Dental Arches Parts of a Tooth • Crown • Root Parts of a Tooth • Crown: part of the tooth covered by enamel, portion of the tooth visible in the oral cavity. • Root: part of the tooth which covered by cementum. • Posterior teeth • Anterior teeth Root • Apex: rounded end of the root • Periapex (periapical): area around the apex of a tooth • Foramen: opening at the apex through which blood vessels and nerves enters • Furcation: area of a two or three rooted tooth where the root divides Tooth Layers • Enamel: the hardest calcified tissue covering the dentine in the crown of the tooth (96%) mineralized. • Dentine: hard calcified tissue surrounding the pulp and underlying the enamel and cementum. Makes up the bulk of the tooth, (70%) mineralized. Tooth Layers • Pulp: the innermost noncalsified tissues containing blood vessels, lymphatics and nerves • Cementum: bone like calcified tissue covering the dentin in the root of the tooth, 50% mineralized. Tooth Layers Tooth Surfaces • Facial: Labial , Buccal • Lingual: called palatal for upper arch. • Proximal: mesial , distal • Contact area: area where that touches the adjacent tooth in the same arch. Tooth Surfaces • Incisal: surface of an incisor which toward the opposite arch, the biting surface, the newly erupted “permanent incisors have mamelons”: projections of enamel on this surface.

Veterinary Dentistry Basics
Veterinary Dentistry Basics Introduction This program will guide you, step by step, through the most important features of veterinary dentistry in current best practice. This chapter covers the basics of veterinary dentistry and should enable you to: ü Describe the anatomical components of a tooth and relate it to location and function ü Know the main landmarks important in assessment of dental disease ü Understand tooth numbering and formulae in different species. ã 2002 eMedia Unit RVC 1 of 10 Dental Anatomy Crown The crown is normally covered by enamel and meets the root at an important landmark called the cemento-enamel junction (CEJ). The CEJ is anatomically the neck of the tooth and is not normally visible. Root Teeth may have one or more roots. In those teeth with two or more roots the point where they diverge is called the furcation angle. This can be a bifurcation or a trifurcation. At the end of the root is the apex, which can have a single foramen (humans), a multiple canal delta arrangement (cats and dogs) or remain open as in herbivores. In some herbivores the apex closes eventually (horse) whereas whereas in others it remains open throughout life. The apical area is where nerves, blood vessels and lymphatics travel into the pulp. Alveolar Bone The roots are encased in the alveolar processes of the jaws. The process comprises alveolar bone, trabecular bone and compact bone. The densest bone lines the alveolus and is called the cribriform plate. It may be seen radiographically as a white line called the lamina dura.

Morphological Integration in the Hominin Dentition: Evolutionary, Developmental, and Functional Factors
ORIGINAL ARTICLE doi:10.1111/j.1558-5646.2011.01508.x MORPHOLOGICAL INTEGRATION IN THE HOMININ DENTITION: EVOLUTIONARY, DEVELOPMENTAL, AND FUNCTIONAL FACTORS Aida Gomez-Robles´ 1,2 and P. David Polly3 1Konrad Lorenz Institute for Evolution and Cognition Research, Adolf Lorenz Gasse 2, A-3422 Altenberg, Austria 2E-mails: [email protected]; [email protected] 3Department of Geological Sciences, Indiana University, 1001 East 10th Street, Bloomington, Indiana 47405 Received June 29, 2011 Accepted October 19, 2011 As the most common and best preserved remains in the fossil record, teeth are central to our understanding of evolution. However, many evolutionary analyses based on dental traits overlook the constraints that limit dental evolution. These constraints are di- verse, ranging from developmental interactions between the individual elements of a homologous series (the whole dentition) to functional constraints related to occlusion. This study evaluates morphological integration in the hominin dentition and its effect on dental evolution in an extensive sample of Plio- and Pleistocene hominin teeth using geometric morphometrics and phyloge- netic comparative methods. Results reveal that premolars and molars display significant levels of covariation; that integration is stronger in the mandibular dentition than in the maxillary dentition; and that antagonist teeth, especially first molars, are strongly integrated. Results also show an association of morphological integration and evolution. Stasis is observed in elements with strong functional and/or developmental interactions, namely in first molars. Alternatively, directional evolution (and weaker integration) occurs in the elements with marginal roles in occlusion and mastication, probably in response to other direct or indirect selective pressures.

Allometric Scaling in the Dentition of Primates and Prediction of Body Weight from Tooth Size in Fossils
AMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY 58%-100 (1982) Allometric Scaling in the Dentition of Primates and Prediction of Body Weight From Tooth Size in Fossils PHILIP D. GINGERICH, B. HOLLY SMITH, AND KAREN ROSENBERG Museum of Paleontology (P.D.G.)and Department of Anthropology (B.H.S. and K.R.), The University of Michigan, Ann Arbor, Michigan 48109 KEY WORDS Primate dentition, Allometry, Body size, Adapidae, Hominoidea ABSTRACT Tooth size varies exponentially with body weight in primates. Logarithmic transformation of tooth crown area and body weight yields a linear model of slope 0.67 as an isometric (geometric) baseline for study of dental allometry. This model is compared with that predicted by metabolic scaling (slope = 0.75). Tarsius and other insectivores have larger teeth for their body size than generalized primates do, and they are not included in this analysis. Among generalized primates, tooth size is highly correlated with body size. Correlations of upper and lower cheek teeth with body size range from 0.90-0.97, depending on tooth position. Central cheek teeth (P: and M:) have allometric coefficients ranging from 0.57-0.65, falling well below geometric scaling. Anterior and posterior cheek teeth scale at or above metabolic scaling. Considered individually or as a group, upper cheek teeth scale allometrically with lower coefficients than corresponding lower cheek teeth; the reverse is true for incisors. The sum of crown areas for all upper cheek teeth scales significantly below geometric scaling, while the sum of crown areas for all lower cheek teeth approximates geometric scaling. Tooth size can be used to predict the body weight of generalized fossil primates.

Dental Integration and Modularity in Pinnipeds Mieczyslaw Wolsan 1, Satoshi Suzuki2, Masakazu Asahara3 & Masaharu Motokawa4
www.nature.com/scientificreports OPEN Dental integration and modularity in pinnipeds Mieczyslaw Wolsan 1, Satoshi Suzuki2, Masakazu Asahara3 & Masaharu Motokawa4 Morphological integration and modularity are important for understanding phenotypic evolution Received: 11 June 2018 because they constrain variation subjected to selection and enable independent evolution of functional Accepted: 26 February 2019 and developmental units. We report dental integration and modularity in representative otariid Published: xx xx xxxx (Eumetopias jubatus, Callorhinus ursinus) and phocid (Phoca largha, Histriophoca fasciata) species of Pinnipedia. This is the frst study of integration and modularity in a secondarily simplifed dentition with simple occlusion. Integration was stronger in both otariid species than in either phocid species and related positively to dental occlusion and negatively to both modularity and tooth-size variability across all the species. The canines and third upper incisor were most strongly integrated, comprising a module that likely serves as occlusal guides for the postcanines. There was no or weak modularity among tooth classes. The reported integration is stronger than or similar to that in mammals with complex dentition and refned occlusion. We hypothesise that this strong integration is driven by dental occlusion, and that it is enabled by reduction of modularity that constrains overall integration in complex dentitions. We propose that modularity was reduced in pinnipeds during the transition to aquatic life in association with the origin of pierce-feeding and loss of mastication caused by underwater feeding. Organisms are organised into multiple identifable parts on multiple levels. Tese parts are distinct from each other because of structure, function or developmental origins. Te fact that parts of an organism are distinguish- able refects their individuality and a degree of independence from each other.

Developmental Disorders of the Dentition: an Update OPHIR D
American Journal of Medical Genetics Part C (Seminars in Medical Genetics) 163C:318–332 (2013) ARTICLE Developmental Disorders of the Dentition: An Update OPHIR D. KLEIN, SNEHLATA OBEROI, ANN HUYSSEUNE, MARIA HOVORAKOVA, MIROSLAV PETERKA, AND RENATA PETERKOVA Dental anomalies are common congenital malformations that can occur either as isolated ﬁndings or as part of a syndrome. This review focuses on genetic causes of abnormal tooth development and the implications of these abnormalities for clinical care. As an introduction, we describe general insights into the genetics of tooth development obtained from mouse and zebraﬁsh models. This is followed by a discussion of isolated as well as syndromic tooth agenesis, including Van der Woude syndrome (VWS), ectodermal dysplasias (EDs), oral‐facial‐ digital (OFD) syndrome type I, Rieger syndrome, holoprosencephaly, and tooth anomalies associated with cleft lip and palate. Next, we review delayed formation and eruption of teeth, as well as abnormalities in tooth size, shape, and form. Finally, isolated and syndromic causes of supernumerary teeth are considered, including cleidocranial dysplasia and Gardner syndrome. © 2013 Wiley Periodicals, Inc.
