Retrospective radiological analysis of cemento-osseous dysplasia.

ABSTRACT

BACKGROUND: Osseous dysplasia (OD) is a form of fibro-osseous lesion located in the jaws that may interfere with the adjacent anatomical structures. OBJECTIVES: The aim of the present study was to evaluate the distribution of radiographic imaging features, the morphological characteristics and the lesion volume of OD with the use of cone-beam computed tomography (CBCT). MATERIAL AND METHODS: The study included radiologically diagnosed lesions followed up for at least 1 year. The prevalence and distribution of the OD types were defined in terms of age, sex, lesion location, teeth, relationship with the anatomical structures, and lesion volume. RESULTS: The mean age gradually increased from the periapical group to the florid group (p = 0.018). It was observed that the mandible was the most frequently affected bone (85.5%) (p < 0.05). The margins of the lesions were well defined, and had an irregular or circular shape. The buccal cortical bone was the most affected structure (84.5%), and the damage in the cortical bone increased with an increase in the lesion volume. With regard to teeth, the most frequent disorder was a discontinuous lamina dura (83.0%). CONCLUSIONS: Osseous dysplasia lesions affect a wide range of different anatomical areas, and show different volume and morphometric characteristics.
