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
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
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

Book Description
A leading orthodontics reference, Orthodontics: Current Principles and Techniques, 5th Edition provides the latest information from the best experts in the field. It reflects today's emerging techniques, including new information on esthetics, genetics, cone-beam and other three-dimensional technologies, and evidence-based treatment. Coverage of diagnosis and treatment ranges from basic to highly complex situations, all in a concise, extensively illustrated format. Also included with this edition is a companion website that includes an electronic version of all chapters, supplemental content in select chapters, and a complete image collection to help with research and presentations. Written by Lee W. Graber, Robert L. Vanarsdall Jr., and Katherine W. L. Vig, along with a team of expert contributors, this is your go-to book for the practical orthodontic information you can use every day. Comprehensive coverage includes foundational theory and the latest on materials and techniques used in today's practice. Full-color photographs make it easy to see and distinguish the subtle differences that are necessary to mastering treatment planning. More than 2,500 images include a mixture of radiographs, clinical photos, and anatomic or schematic line drawings, showing examples of treatments, techniques, and outcomes. Detailed case studies guide you through the decision-making process, showing the consequences of various treatment techniques over time. Extensive references cite the latest in orthodontic research, so it's easy to follow up on evidence-based information. Authoritative research is provided by a team of three experienced, renowned authors/editors along with a team of worldwide experts. Cutting-edge content includes the latest concepts and techniques in orthodontics, including new coverage of temporary anchorage devices, self-ligating bracket biomechanics, clear aligner treatments, technological advances in imaging, and lasers. Improved organization separates topics into six parts and 29 chapters, enhancing both learning and research. Chapter outlines serve as a handy reference tool for practitioners and researchers. New lead author Dr. Lee Graber adds a fresh perspective to the experience of authors Drs. Robert Vanarsdall Jr., and Katherine W. L. Vig. Access to a companion website includes an electronic version of all chapters, plus case studies, a complete image collection, and supplemental content.
