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
