| alveolar | <anatomy> Of, pertaining to, or resembling, alveoli or little cells, sacs, or sockets. Alveolar processes, the processes of the maxillary bones, containing the sockets of the teeth. Origin: L. Alveolus a small hollow or cavity: cf. F. Alveolaire. Source: Websters Dictionary (01 Mar 1998) |

| alveolar abscess | A pocket of pus adjacent to or within (apical abscess) the tooth's root caused by plaque and calculus invasion. Symptoms include tooth pain and tenderness that may be accompanied by facial swelling and a fever. Treatment includes antibiotics and a thorough cleansing of the infected site by a dentist. See: apical abscess. (27 Sep 1997) |
| alveolar adenocarcinoma | <tumour> Adenocarcinoma of the lung in which tumour cells form structures resembling alveoli. (05 Mar 2000) |
| alveolar air | The gas in the pulmonary alveoli, where O2-CO2 exchange with pulmonary capillary blood occurs. Synonym: alveolar air. (05 Mar 2000) |
| alveolar angle | The angle between the horizontal plane and a line connecting the base of the nasal spine and the middle point of the projection of the alveolus of the maxilla. (05 Mar 2000) |
| alveolar arch of mandible | The free margin of the alveolar process of the mandible. Synonym: arcus alveolaris mandibulae, limbus alveolaris. (05 Mar 2000) |
| alveolar arch of maxilla | The free border of the alveolar process of the maxilla. Synonym: arcus alveolaris maxillae, limbus alveolaris. (05 Mar 2000) |
| alveolar-arterial oxygen difference | The difference or gradient between the partial pressure of oxygen in the alveolar spaces and the arterial blood: P(A-a)02. Normally in young adults this value is less than 20 mm Hg. See: alveolar gas equation. (05 Mar 2000) |
| alveolar atrophy | Diminution in size of the supportive tissues of the teeth due to lack of function, reduced blood supply, or unknown causes. (05 Mar 2000) |
| alveolar body | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar bone | That portion of bone in either the maxilla or the mandible which surrounds and supports the teeth. (12 Dec 1998) |
| alveolar bone loss | The resorption of bone in the supporting structures of the maxilla or mandible as a result of periodontal disease. (12 Dec 1998) |
| alveolar border | The most occlusal edge of the alveolar bone. Synonym: alveolar process. (05 Mar 2000) |
