 Dentistry, dentistry is a branch of medicine that consists of the study, diagnosis, prevention and treatment of diseases, disorders and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial jaw and facial area. Though primarily associated with teeth among the general public, the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the cranial facial complex including the temporomantibular joint and other supporting, muscular, lymphatic, nervous, vascular and anatomical structures. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology, the study of the mouth and its disorders and diseases for which reason the two terms are used interchangeably in certain regions. Dental treatments are carried out by a dental team, which often consists of a dentist and dental auxiliaries, dental assistants, dental hygienists, dental technicians, as well as dental therapists. Most dentists either work in private practices, primary care dental hospitals or secondary care institutions presence, armed forces bases, etc. The history of dentistry is almost as ancient as the history of humanity and civilization. With the earliest evidence dating from 7,000 BC, remains from the early Harappan periods of the Indus Valley Civilization See.Question mark 3,300 BC show evidence of teeth having been drilled dating back 9,000 years. It is thought that dental surgery was the first specialization from medicine.
