La technique de l'ultrasonographie et son application, notamment en chirurgie orale et maxillo-faciale, se répandent de plus en plus. En raison de sa rentabilité et de sa nature non ionisante, cette technique devient de plus en plus populaire parmi les dentistes. Toutes sortes d'utilisations de l'ultrasonographie sont abordées dans ce livre, ce qui illustre la flexibilité et la variabilité de l'ultrasonographie. Le faible coût de cette technique et de la machine utilisée est l'un des principaux facteurs de son utilisation croissante à des fins diverses. En ce qui concerne la région buccale et maxillo-faciale, cette technique, jusqu'à présent, a fourni des résultats précis et donc des options de traitement plus précises pour les pathologies buccales et maxillo-faciales. Ce livre aidera les cliniciens, les chirurgiens et les radiologues à comprendre les applications de l'échographie en chirurgie buccale pour diagnostiquer et traiter correctement les pathologies buccales et maxillo-faciales.

Die Ultraschalltechnik und ihre Anwendung, insbesondere in der Mund-, Kiefer- und Gesichtschirurgie, verbreiten sich mit jedem Tag. Aufgrund der Kosteneffizienz und der nicht-ionisierenden Natur dieser Technik wird sie bei den Zahnärzten immer beliebter. In diesem Buch werden alle Arten von Ultraschallanwendungen besprochen, die die Flexibilität und Vielseitigkeit des Ultraschalls zeigen. Die geringen Kosten dieser Technik und der dafür verwendeten Geräte sind einer der Hauptfaktoren für ihre zunehmende Verwendung für verschiedene Zwecke. Was den Mund- und Kieferbereich betrifft, so hat diese Technik bisher genaue Ergebnisse und damit präzisere Behandlungsmöglichkeiten für Mund- und Kieferkrankheiten geliefert. Dieses Buch wird den Klinikern, Chirurgen und Radiologen helfen, die Anwendungen der Ultraschalltechnik in der Oralchirurgie zu verstehen, um orale und maxillofaziale Pathologien richtig zu diagnostizieren und zu behandeln.

Pigmentation is a discoloration of the oral mucosa or gingiva due to the wide variety of lesions and conditions. The pigmentation in oral cavity may be caused by the accumulation of one or more pigments which further leads to change in color of the tissues. There are several degrees of chromatic variegation observed in both physiological and pathological conditions. This coloration is caused by number of factors, one of which is pigmentation. Normal regional variations in oral pigment from greatest to least occur in gingiva, buccal mucosa, hard palate, tongue, soft palate, and floor of the mouth. The identification of pigmented tissue within the oral cavity may present a diagnostic dilemma for the clinician. Evaluation of patient presenting with a pigmented lesion should include a full medical and dental history, extra oral and intra oral examinations and in some cases biopsy and laboratory investigations.

Traditional orthognathic surgery & craniofacial reconstruction procedures have gained a generalized acceptance & experienced wide spread success, but many limitations are associated with acute advancement of the osteotomized bone segment. One of the major limitation is the inability of the soft tissue to be actually stretched. Generally the craniofacial deformities require such a large skeletal movement that surrounding soft tissue cannot adapt to their new position resulting in degenerative changes, relapse & compromised function & aesthetics. Distraction osteogenesis gives new direction to the treatment of these anomalies. "Distraction osteogenesis is a biological process of new bone formation between the surfaces of bone segments that are gradually separated by incremental traction" The traction force applied on bone also create tension in the surrounding tissue, initiating a sequence of adaptive changes termed as "distraction histogenesis". This book deals with the protocols, biology of bone formation, techniques, distractors, recent advancements and complications in the surgery of distraction osteogensis.

Sucrose (table sugar) is considered as sugar by most of the people. Though sweet, sugars are the causes for many bitter experiences faced by the modern day civilized man. Sugar, directly or indirectly is considered as culprit for many diseases like diabetes, obesity, atherosclerosis, etc., which prompted the search for a suitable substitute.' At this given point of time, there is no such substitute which can replace sugar (which is versatile) in all aspects. The dental profession shares an interest in the search for safe, palatable sugar substitutes, as there is established evidence suggesting the causal relationship between sugar and dental caries. Use of sugar substitutes in preventive dentistry is gaining importance. Replacing sugar with a suitable sugar substitute to combat dental caries is an option wide open.This is a small effort to give an elaborate discussion on sugar substitutes and their role in dental health and also remove the myths about them and give a clear cut idea on them.
