Various kinds of mineralization have been found in many biological systems. Investigations made at a microscopical level using various sophisticated analytical methods and using principles developed in different fields have clarified their mechanisms very much. Sometimes, very similar phenomena have been found in the mineralized tissues of completely different biological systems. Compilation and comparative investigations of such findings obtained from the many specimens systematically collected contribute a great deal to an understanding of the crucial mechanisms and significance of biominerali zation which originated in very primitive organisms and remain in advanced ones. Previously, the functional significance of mineralized tissues was considered mainly from an anatomical point of view based upon their morphological and structural features. However, the recent advance of investigations has made it possible to interpret the func tional significance of biomineralization not only from local and mechanical points of view, but also from a systemic and phylogenetic point of view. It is also well-known that biomineralization has contributed in various ways to geological and oceanographical conditions of the environment in which the organisms were living. During this process, the mechanisms of biomineralization may have evolved to maintain harmony between organisms and their environments."

A different kind of book! The clivus of skull base is an area difficult to reach in neurosurgery, otorhinolaryngolo- gy, maxillo-facial surgery, plastic surgery, reconstructive surgery, and orthopedic surgery. It is for this reason that the various specialities gave found different approaches for different operations.

The use of the compressed air-driven turbine for the activation of surgical burs and saws as developed by Dr. Robert M. Hall has been a boon for the plastic, max illofacial, and oral surgeon. The development of air instrument surgery coincided with the opening of new vistas in surgery in the area of craniofacial surgery. Cranio facial osteotomies for orbital (ocular) hypertelorism, for the deformities of cranio stenosis (Cronzon's disease, Apert's syndrome) and subcranial osteotomies at various levels of the facial skeleton have brought about dramatic improvements in the form of the facial substructure in patients with gross deformities. In many of these maxillofacial deformities the facial skeleton and dento-alveolar processes must be advanced, recessed or expanded in the lateral dimension. In such cases maloc clusion of the tceth is usual; this is corrected by intermaxillary fixation of the mo bilized bony structures which also reestablishes adequate relationships between the dento-alveolar processes of the upper and lower jaws. This brings us to the subject of surgical orthodontics, a field that is just beginning to expand; its development should bring about closer collaboration between surgeon and orthodontist, resulting in rapid and efficient improvement of malocclusion. The absence of vibration characteristic of the air-driven turbine, in contrast to the mechanically driven drill, allows the surgeon to carry out delicate and precise surgical procedures with less fatigue to himself."

In Videofluorscopic Studies of Speech in Patients with Cleft Palate, Drs. M.L. Skolnick and E.R. Cohn present multiview videofluoroscopy as a technique for the radiological evaluation of speech defects in patients with cleft palate. Dr. Skolnick's invaluable contributions as both the originator and leading authority on the subject are discussed in a concise, clinical fashion. Topics examined include the anatomy and imaging of the velopharyngeal portal; the equipment and techniques of multiview videofluoroscopy; the interpretation of results and various patterns of velopharyngeal closure; Passavant's Ridge and patterns of velopharyngeal closure; normal and abnormal speech production; and the evaluation of test results. This book is the only source which concisely and completely describes the technique and its interpretations for those who need a description of the clinical procedure.

Since 1958 the Association for the Study of Internal Fixation (ASIF) has worked to establish the experimental and biomechanical prin ciples of the operative treatment of fractures. It has been proven that immediate, pain-free mobilization, made possible by stable internal fixation, is the key to restoring function in a fractured extremity. The same principles were applied in 1972173 by Roland Schmoker, who developed a universal plate and sophisticated instrument set designed initially for the treatment of comminuted fractures of the mandible. To extend the applications of his plate to reconstructions after ex tensive tumor resections, he supplemented the device with tem poromandibular joint prostheses and anchoring elements for the at tachment of dentures. He first tested the functional stability of these implants experimentally in sheep. Later he found that the minipig had a more human-like jaw shape and masticatory action, and so he tested the implants in 37 mini pigs that underwent extensive mandibular re sections without bone grafting, using sequential dye injections and postoperative weight gain to chart the progress of osseous regener ation. Seven other animals were not operated and served as controls."

Dental caries is a process which may take place on any tooth surface in the oral cavity where dental plaque is allowed to develop over a period of time. The new edition of this popular, clinically relevant book provides the biological background required by dentistry students in order to take the science of cariology to the chairside in the management of patients. It describes the cause of caries and its progression in enamel and dentine. Methods of prevention including plaque control, use of fluoride and dietary control are described. The indications for operative management are covered, as well as how to teach patients their essential role in caries control.
Illustrated in full colour and written in an accessible style, this book will appeal to dental students as well as dental nurses, dental health educators, hygienists, and therapists. It will also be of use to scientists working in the field of clinical cariology and to qualified dentists who wish to update their knowledge.

This book presents a circumspective overview and update of the present existing knowledge of the biology, chemistry and pathophysiology of the dental pulp. It details numerous observations of a group of highly specialized investigators who have united in the common purpose of presenting their observations for the benefit of clinicians, teachers, researchers and students. Fortunately, the dental literature presents abundant research findings about pulp biology and the pulp's responses to various stimuli. This abundance has resulted in an increased interest and expansion of research on this subject. For example, publications abound on the response of pulp tissue to various medications and to a variety of types of dental materials which may be placed near to or at some distance from the pulp through the medium of dentine. One of the reasons the pulp is of such interest is that it not only provides the vitality to the teeth but also produces the dentine - both the primary and secondary, as well as reparative. The latter-type dentine is a result of the pulp's functions in response to disease as the former dentine is in response to health. As an example, some investigators have reported the effects of cutting of dentine and the placement of restorations in dentine which in turn reflect changes on the pulp tissue. These reports have raised a number of questions, which in turn have created a need for answers.

The Psychology of the Dentist-Patient Relationship acquaints dentists with the underlying interpersonal dynamics of their professional work. The author has reviewed the dental and psychological literature about the behavior of dentists and their patients, and used this evidence to evaluate critically the various theoretical models of the dentist-patient relationship. A major aim of this book is to show how the application of soundly based psychological theory and practice can improve patient management, reduce the stress of practicing dentistry, and contribute to the design of effective community dental health campaigns.

Distraction osteogenesis is a technique of bone lengthening developed by the late Dr. Ilizarov of Russia. It has been applied to the lower extremities with amazing success for the correction of non-unions following fractures as well as underdeveloped limbs. Dr. McCarthy and his colleagues at NYU have developed techniques of distracting various components of the craniofacial skeleton. These techniques hold considerable promise for reconstructive surgery, allowing the surgeon to make precise changes in the lenthening and shape of the new craniofacial bone. This volume is the first book of its kind, bringing together the pioneers of these revolutionary new techniques. An international group of experts present their clinical and laboratory experience with destraction of the cranial vault, orbit, midface and zygoma, and mandible, as well as the prinicples of distraction, biomechanics, and the physiology of bone healing and remodeling. Two hundred illustrations elucidate the techniques. This book is a must for all reconstructive plastic surgeons, maxillofacial surgeons, and oral surgeons.

Cancer may be regarded as a group of diseases characterized by an (i) abnormal growth of cells (ii) ability to invade adjacent tissue and even distant organs and(iii) the eventual death of the affected patient if the tumor has progressed beyond that stage when it can be successfully removed . Cancer can occur at any site or tissue of the body and may involve any type of cells. In 1995 the south East Asia Region of WHO found that there is great majority of cancers of the oral cavity in India . These and other international variations in the pattern of oral cancer are attributed to multiple factors such as environmental factors, food habits, life style, genetic factor or even inadequacy in detection and reporting of cases. Oral cancers are also predominantly environment related and have socio -cultural relationship31. Majority of malignancies arising in oral mucosa are epithelial in origin approximately 90% of being squamous cell carcinomas .Management of oral carcinoma includes early diagnosis, accurate assessment of prognosis and proper therapeutic intervention. Tumor markers play an important role in all the aspect of management of oral cancer. Tumor markers are a group of proteins(oncoprotein, immunoglobulin, albumin, globulin), hormones(adrenal corticotropic hormone (ACTH), calcitonin, catecholamines), enzymes(acid phosphatase, alkaline phosphatase, amylase, creatine kinase), receptors(estrogen receptor, progesterone receptor, interleukin-2 receptor, and epidermal growth factor receptor), and other cellular products that are over expressed (produced in higher than normal amounts) by malignant cells48. Tumor markers are usually normal cellular constituents that are present at normal or very low levels in the blood of healthy persons and the Carcinogenesis (meaning literally, the creation of cancer) is the process by which normal cells are transformed in to cancer cells. Carcinogenesis is a multistep process resulting from the sequential perturbation of both positive and regulatory networks that normally allow the somatic cell to live a cooperative existence within the society of normal cells that comprise an organism. Normal cells even programmed to give their own life for the good of the organism. Any genetic or epigenetic changes that allow a cell to escape these societal constraints represent a step toward cancer. Survival of the fittest cells allows for the clonal expansion of progeny cells with ever increasing numbers of genetic or epigenetic changes that favor even greater antisocial and selfish behavior of the cancer cell within the organism. Carcinogenesis is caused by mutation of the genetic material of normal cells, which upsets the normal balance between proliferation and cell death. This results in uncontrolled cell division and tumor formation. The uncontrolled and often rapid proliferation of cells can lead to benign tumors. Some types of these may turn in to malignant tumors.
