Radiopaque lesions and lesions of mixed density are less frequent than radiolucent lesions of the jawbones. They comprise a spectrum of odontogenic and non-odontogenic lesions. The latter group includes inherited and developmental disorders, osteomyelitis, and benign and malignant primary bone tumors and metastases. Most odontogenic radiopaque or mixed lesions are either related to the apex or more rarely to the crown of the tooth, although there are exceptions to this rule. Some lesions, such as a torus mandibularis and torus palatinus, have a characteristic location, whereas others show no relationship to the dentition. This article describes the most characteristic and prevalent radiopaque and mixed lesions of the jaws and their imaging characteristics. Paget's disease, fibrous dysplasia, and rare sclerotic bone diseases of the maxillofacial bones are discussed elsewhere in this issue. Careful correlation of clinical presentation, panoramic radiographs, cone beam computed tomography, and histopathology are the cornerstones for appropriate lesion characterization.
颌骨的不透射线病变和混合密度病变比透射线病变少见。它们包括一系列牙源性和非牙源性病变。后者包括遗传性和发育性疾病、骨髓炎以及良性和恶性原发性骨肿瘤和转移瘤。大多数牙源性不透射线或混合病变与牙尖或更罕见的牙冠有关，尽管对此规则有例外。一些病变，如下颌骨隆突和腭骨隆突，具有特征性位置，而其他病变与牙列无关。本文描述了颌骨中最具特征性和常见的不透射线和混合病变及其影像学特征。本期刊物的其他地方讨论了佩吉特病、纤维结构不良以及颌面部罕见的硬化性骨疾病。仔细结合临床表现、全景片、锥形束 CT 和组织病理学是对病变进行适当特征描述的基石。
