Abstract
Abstract A method and apparatus are disclosed for saving an exarticulated tooth. The tooth is grasped by its crown, so as not to harm the periodontal membrane. The tooth is then placed in a net which is attached to a basket. The net and basket are immersed in a modified saline solution which preserves the cells of the periodontal membrane. The solution is held in a container which accommodates the net and basket. The lid of the container has a sponge attached to its interior surface. The container is closed, and the tooth and patient are taken to a dentist. The dentist removes the container lid, and lays the lid on a table or other surface, so that the sponge faces upward. The dentist then lifts the basket, with the tooth, out of the solution, and inverts the net so that the tooth falls out onto the sponge. The dentist grasps the tooth with a forceps and reimplants it in the patient's mouth.
