Author Description

The interface between orthodontics and periodontolgy is as broad as any between two disciplines in clinical dentistry. Controlled tooth movements utilize the dynamic nature of the periodontium which remodels actively when external forces are applied. Periodontal tissues are also continuously at risk from plaque-induced diseases that compromise the support of the dentition. The accumulation of plaque is enhanced when patients wear orthodontic appliances and the dental hygienist has a vital role to play before, during, and after orthodontic treatment. Changes in tooth relationships are often a consequence of periodontal disease. When the condition has been controlled orthodontic treatment may be indicated to, for example, align drifted incisors, or to upright molars that have tipped into extraction spaces.The objective of this book is to explore fully the interrelationships between the periodontium in both health and disease, and orthodontics. It is not a text that is aimed purposely towards the specialist management of orthodontic or periodontal cases. We have instead examined exhaustively the common ground upon which the orthodontist and periodontist are often called upon to meet and collaborate on cases that demand multi-disciplinary care.The text is presented in two parts. Part I comprises three chapters covering the basic sciences. Chapter 1 deals with the anatomy and physiology of the peridontium and investigates the role of dental anatomy in the initiation and progression of periodontal disease. Chapter 2 summarizes the microbiology and pathogeneisis of periodonatla disease and it is evident that many of the biological mediators which are involved in the perpetuation of disease are also implicated in the day-to-day remodelling of the supporting tissues. Chapters 3 studies the histological aspects of orthodontic tooth movements and looks at the biological mechanisms involved. Part II comprises the remaining six chapters. Chapter 4 discusses the exmaination and t
