Abstract：
The gingiva is often the site of localized growths that are considered to be reactive rather than neoplastic in nature. Many of these lesions are difficult to be identified clinically and can be identified as specific entity only on the basis of typical and consistent histomorphology. Peripheral ossifying fibroma is one such reactive lesion. It has been described with various synonyms and is believed to arise from the periodontal ligament comprising about 9% of all gingival growths. The size of the lesion is usually small, located mainly in the anterior maxilla with a higher predilection for females, and it is more common in the second decade of life. A clinical report of a 12-year-old girl with a large peripheral ossifying fibroma in the posterior maxilla showing significant growth and interference with occlusion is presented.
摘要：
牙龈通常是局部生长的部位，本质上被认为是反应性的而不是肿瘤性的。这些病变中的许多在临床上难以识别，并且只能根据典型且一致的组织形态学来识别为特定实体。外周骨化性纤维瘤是一种这样的反应性病变。它已经用各种同义词进行了描述，并且被认为是由牙周膜引起的，占所有牙龈生长的约9％。病变的大小通常很小，主要位于前上颌骨，对女性的偏爱较高，在生命的第二个十年中更为常见。提出了一个12岁女孩的临床报告，该女孩在上颌骨后部有一个大的周围骨化性纤维瘤，显示出显着的生长和对咬合的干扰。
