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.

Figure 1: A panoramic radiograph shows a radiolucent rim at the periphery of lesions (arrows) diagnosed as periapical cemento-osseous dysplasia.

Mentions: Periapical cemento-osseous dysplasia arises in the anterior mandible, generally in patients over 30 years of age. A female predilection has been found, and almost 70% of cases occur in blacks. Periapical cemento-osseous dysplasia has no symptoms and the teeth in the affected area remain vital. Hence, the lesion is detected in routine radiographs. A majority of periapical cemento-osseous dysplasias are delineated with a well-defined radiolucent border.12 The incidence of periapical cemento-osseous dysplasia is 2-3/1000 in the general population.13 The radiographic appearance of periapical cemento-osseous dysplasia may vary widely. In the early stage, lesions show a periapical radiolucent defect that subsequently develops very small radiopacities. In the later stage, tiny radiopaque foci enlarge, coalesce, and undergo further substantial opacification. They consist of dense cementum-like and/or ground-glass areas rimmed by a radiolucent halo.7 Eskandarloo and Yousefi12 reported a case in which a radiolucent rim was found around the radiopaque lesion in the teeth apices (Fig. 1). The same finding was reported by Komabayashi and Zhu.14
