Radiolucent rim as a possible diagnostic aid for differentiating jaw lesions.

Mortazavi H, Baharvand M, Rahmani S, Jafari S, Parvaei P - Imaging Sci Dent (2015)

Bottom Line: We used general search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks to find relevant studies by using keywords such as "jaw disease," "jaw lesions," "radiolucent rim," "radiolucent border," and "radiolucent halo." More than 200 articles were found, of which 70 were broadly relevant to the topic.We ultimately included 50 articles that were closely related to the topic of interest.We propose a novel subcategory, jaw lesions with a radiolucent rim, which includes eight entities.

ABSTRACT
In this study, we formulate a new proposal that complements previous classifications in order to assist dental practitioners in performing a differential diagnosis based on patients' radiographs. We used general search engines and specialized databases such as Google Scholar, PubMed, PubMed Central, MedLine Plus, Science Direct, Scopus, and well-recognized textbooks to find relevant studies by using keywords such as "jaw disease," "jaw lesions," "radiolucent rim," "radiolucent border," and "radiolucent halo." More than 200 articles were found, of which 70 were broadly relevant to the topic. We ultimately included 50 articles that were closely related to the topic of interest. When the relevant data were compiled, the following eight lesions were identified as having a radiolucent rim: periapical cemento-osseous dysplasia, focal cemento-osseous dysplasia, florid cemento-osseous dysplasia, cemento-ossifying fibroma, osteoid osteoma, osteoblastoma, odontoma, and cementoblastoma. We propose a novel subcategory, jaw lesions with a radiolucent rim, which includes eight entities. The implementation of this new category can help improve the diagnoses that dental practitioners make based on patients' radiographs.

Mentions: Florid cemento-osseous dysplasia has also been described using the terms multiple cemento-ossifying fibroma, sclerosing osteomyelitis, multiple osteoma, sclerosing osteitis, periapical cementoblastoma, multiple enostosis, gigantiform cementoma, and florid osseous dysplasia.1019 The exact etiology of florid cemento-osseous dysplasia is still unknown. Most authorities have suggested that the pathogenesis of florid cemento-osseous dysplasia is related to the periodontal ligament, because most florid cementoosseous dysplasias are seen close to the periodontal ligament with identical histopathologic features. However, a few authors have suggested that remnants of cementum in the bone after extraction might play a role in the etiology of this type of lesion.19 Florid cemento-osseous dysplasia may be familial, with an autosomal dominant inheritance pattern, but few examples of a familial pattern have been reported in the literature.20 It predominantly occurs in middle-aged to older black women, and the male-to-female ratio has been reported as 1 : 2.6.19 Florid cemento-osseous dysplasia most commonly appear as bilateral, symmetrical, and extensive lesions in all four posterior quadrants of the jaws, in the molar and premolar regions.10 Florid cementoosseous dysplasia has three types of radiographic appearance depending on its stage: the first or osteolytic stage (a well-defined radiolucent area with loss of lamina dura and periodontal ligament), the second or cementoblastic stage (small radiopacities appear in the radiolucent area due to the deposition of cementum-like droplets in fibrous tissue), and the last stage (lobular radiopacity throughout the lesion, surrounded by a radiolucent area).19 Beylouni et al.10 noticed cyst-like radiolucent areas around some radiopaque lesions in florid cemento-osseous dysplasia. Köse et al.19 and Kutluay Köklü et al.20 reported ovoid radiopaque masses in wide radiolucent spaces in the periapical areas of all molars in both quadrants of the mandible in the panoramic view (Fig. 3).
