文档介绍：Extraction of Teeth
Extraction is a surgery
The extraction of teeth, however accomplished, is a surgical operation involving bony and soft tissues of the oral cavity, access to which is restricted by the lips and cheeks, and further complicated by the movement of the tongue and mandible.
It is essential that this phase of oral surgery be given the same careful study and application of sound surgical principles as is given to surgery in any other part of the human body.
