Book Description
Dental anomalies of number, shape, and position are frequently analysed in the orthodontic and clinical literature but are rarely discussed in an anthropological or archaeological context. Dental anomalies and occlusal disorders are often hypothesised to be the result of a modern, urbanised lifestyle as a response to reduced masticatory stress and subsequent crowding of the dentition. This study of skulls from Classical to medieaval Macedonia and England examines the relationship between craniofacial variation and the expression of dental anomalies. Standard craniometric measurements were taken to estimate relative sizes of cranial functional complexes and determine whether or not, or to what extent, changes in the shape or size of these variables were associated with the expression of dental anomalies. Statistical analyses determined that the null hypothesis, that there is no relationship between craniometrics and dental anomalies, can be rejected. A number of dental anomalies were found to have a relationship with reduced sizes in cranial and masticatory elements, although dental crowding was not as significant a factor in masticatory complex reduction. A cause and effect relationship cannot be determined but the data presented here suggests that both heredity and environmental causes may be influential in the expression of dental anomalies.

Book Description
Dental defects may be the physical expression of genetic defects, and so they can often be seen in a variety of syndromes associated with malformations of organs. However, dental defects are often not recognized, identified, nor characterised despite representing a possible diagnostic sign for an undiagnosed condition. This book addresses this gap by providing an understanding of dental genetics and its developmental biology counterpart. With approximately seventy well-illustrated examples, the authors present the clinical oro-facial manifestations accompanying various syndromes, providing the necessary knowledge for diagnostic purposes, as well as giving insight into recent development for each specific condition. The clarity and format of this book make it an ideal support guide both in the clinic and while conducting research. Comprehensive examination of dento/oro/craniofacial anomalies Well-illustrated examples Presented in a compact, easy to use format

Book Description
This book provides the practitioner with a framework for establishing a diagnosis and developing a suitable treatment plan in patients presenting with a range of developmental defects of the teeth. The conditions covered include failure of tooth eruption, hypodontia, premature tooth exfoliation, defects of enamel development, and defects of dentin development, with full consideration of both syndromic and non-syndromic defects. In each case the phenotype and genotype are first described, followed by diagnostic information, including the availability of genetic testing, and treatment options. Summarizing tables are used to highlight the key diagnostic features, and helpful illustrated case presentations are included. Cleft palate is also addressed, with details on etiology, phenotypes, treatment timing and approaches, and dental management. The closing chapter provides stimulating reflections on potential future directions in the diagnosis and treatment of these disorders.

Book Description
There's a silent epidemic in western civilization, and it is right under our noses. Our jaws are getting smaller and our teeth crooked and crowded, creating not only aesthetic challenges but also difficulties with breathing. Modern orthodontics has persuaded us that braces and oral devices can correct these problems. While teeth can certainly be straightened, what about the underlying causes of this rapid shift in oral evolution and the health risks posed by obstructed airways? Sandra Kahn and Paul R. Ehrlich, a pioneering orthodontist and a world-renowned evolutionist, respectively, present the biological, dietary, and cultural changes that have driven us toward this major health challenge. They propose simple adjustments that can alleviate this developing crisis, as well as a major alternative to orthodontics that promises more significant long-term relief. Jaws will change your life. Every parent should read this book.

Book Description
An appreciation of the genetic and environmental determinants of tooth size is fundamental to an understanding of the metric variation of teeth in humans. Thus, besides imparting a sound knowledge of the theories of dental inheritance, development and evolution, this book has an important role in demonstrating the diverse practical applications of odontometrics. A particular feature of the book is the inclusion of numerous tables which bring together a vast body of information on tooth size in different population groups. Students of oral biology, orthodontics, physical anthropology, human biology, forensic science and archaeology will find this work of great value as a text and reference source. As Professor Phillip Tobias writes in the foreword, 'The breadth of Dr Kieser's reading, and his mastery of a staggering array of anthropological, evolutionary, embryological, orthodontic and statistical concepts shine through every page of this work'.

Book Description
Etiology-Based Dental and Craniofacial Diagnostics explores the role of embryology and fetal pathology in the assessment, diagnosis, and subsequent treatment planning of a wide range of disorders in the dentition and craniofacial region. Initial chapters cover various aspects of normal dental and craniofacial development, providing the necessary biological background for understanding abnormal patient cases. Chapters then focus on the etiology behind a wide range of cases observed in everyday practice—including deviations in tooth morphology and number, tooth eruption, root and crown resorption, and craniofacial malformations, disruptions and dysplasia. Unique new work from a leading authority in orthodontics, craniofacial embryology and fetal pathology Demonstrates how human prenatal development offers unique insights into postnatal diagnosis and treatment Clinical significance and implications are highlighted in summaries at the end of each chapter Ideal for postgraduate students in orthodontics, paediatric dentistry and oral medicine
