Тема №17. Oral Surgery

1. Read the text and answer the questions.

Oral surgery is the branch of dentistry concerned with the study of dental diseases, traumatic injuries and diseases of the teeth, jaws, oral tissues where surgical method are used. Oral surgery is closely connected with therapeutic surgery (oral therapy), oral orthopedics, pediatric dentistry, and a number of medical disciplines – therapy, surgery, radiology and others.

Surgical operations on teeth and the oral cavity have been known since ancient times. Tooth extraction is the most commonly used dental operation. It is usually performed in the cases where conservative treatment is unsuccessful. It helps to stop the spread of the inflammatory process on the surrounding tissues and to avoid complications.

Sometimes the tooth is extracted when it is the source of infection as in acute osteomyelitis. In this case drainage should be performed as soon as possible. The patient should be well taken care of. In some cases when the tooth is far gone and cannot be restored it is necessary to extract it as well. It is better to replace it by denture in order to have good esthetic results and function.

Teeth may be traumatized; the trauma may be so severe that teeth become luxated, fractured, or even comminuted. In this case the prognosis is unfavourable. A totally displaced tooth may be replanted but generally should be removed. Extraction of a tooth is the last alternative in its treatment.
