| Tooth, Howard | <person> English physician, 1856-1925. See: Charcot-Marie-Tooth disease. Synonym: dens. (05 Mar 2000) |
| tooth, impacted | A tooth that is prevented from erupting by a physical barrier, usually other teeth. Impaction may also result from orientation of the tooth in an other than vertical position in the periodontal structures. (12 Dec 1998) |
| tooth injuries | Traumatic or other damage to teeth including fractures (tooth fractures) or displacements (tooth luxation). (12 Dec 1998) |
| tooth ligation | The binding together of teeth with wire for stabilization and immobilization following traumatic injury or orthognathic surgery, or during periodontal therapy. (05 Mar 2000) |
| tooth loss | The failure to retain teeth as a result of disease or injury. (12 Dec 1998) |
| tooth mobility | Horizontal and, to a lesser degree, axial movement of a tooth in response to normal forces, as in occlusion. It refers also to the movability of a tooth resulting from loss of all or a portion of its attachment and supportive apparatus, as seen in periodontitis, occlusal trauma, and periodontosis.

| tooth preparation | Procedures carried out with regard to the teeth or tooth structures preparatory to specified dental therapeutic and surgical measures. (12 Dec 1998) |
| tooth preparation, prosthodontic | The selected form given to a natural tooth when it is reduced by instrumentation to receive a prosthesis (e.g., artificial crown or a retainer for a fixed or removable prosthesis). The selection of the form is guided by clinical circumstances and physical properties of the materials that make up the prosthesis. (boucher's clinical dental terminology, 4th ed, p239) (12 Dec 1998) |
