颌骨特发性骨硬化的X线调查

Radiographic investigation of idiopathic osteosclerosis of jaws

作者调查１３２１例全口牙片，检出颌骨特发性骨硬化（ＩＯ）７５例（８０个病灶），发生率为５．７％。其中，孤立特发性骨硬化（Ｓ１Ｏ）占４６．３％，牙根尖周特发性骨硬化（ＰＩＯ）占３７．５％，牙根间特发性骨硬化（ＩＩＯ）占１６．２％。ＩＯ主要发生于下颌骨。本组下颌第一前磨牙至下颌第一磨牙区病灶数占６０％。各年龄组间无显著性差异（Ｐ＞０．０５）

Full-mouth radiographs of 1321 patients were examined for the presence of radiopacitics that could not be attributed to any known sources of bone formation. A total of 75 patients exhibited these foci of idiopathic osteosclerosis. The incidence of disease is 5. 7%, including SIO 46. 3%, PIO 37. 5%,IIO 16. 2%. The majority of the opacities were found in the mandible, especially from the mandibular first premolar to first molar region (65%). The lesion was most prevalent in the first three decades of life.
