About

COD lesions effect a wide range of different anatomical areas, show different volume and morphometric characteristics.

Full description

Fibro-osseous lesions of the jaws are one of the important lesion groups for which identification and diagnosis create clinical difficulties. In previous studies, the features of the lesions and the effects of COD on anatomical structures were analysed via CBCT images by measuring the lesion's dimensions linearly for the first time in the Brazilian population. However, 3D measurements of the volume need to be taken to assess the actual spread over adjacent anatomical structures. The purpose of this retrospective study is to measure the volume of the lesions that have been diagnosed as COD in the Turkish population by using 3D images. This will contribute to an advanced study conducted on the global population to observe a change in these morphologies with respect to different geographical and ethnic origins.

Enrollment: 46 patients

Inclusion criteria

• They were diagnosed with fibro-osseous lesions with the help of cone beam computed tomography between 2017 and 2020 were included in the study.
• The lesions diagnosed radiologically and followed up for at least one year were included in this study.

Exclusion criteria

-Radiographs with insufficient diagnostic images were not included.

Trial design

46 participants in 3 patient groups

Group 1. Periapical Cemento-Osseous Dysplasia

Description:

In Periapical Cemento-Osseous Dysplasia , the lower anterior teeth are usually affected. In these lesions, normal bone is replaced by fibrous tissue that contains amorphous vascularised calcifications. In the early stage, it can mimic a periapical lesion, but it is usually associated with vital teeth, without any clinical complaint, and it requires no intervention. Histopathologically, the lesion is similar to fibrous dysplasia and ossifying fibroma.

Treatment:

Other: The data of patients who had applied to the clinic for various reasons and were diagnosed with fibro-osseous lesions

Group 2. Focal Cemento-Osseous Dysplasia

Description:

It occurs in a single area of the posterior teeth. Its radiographic and histolopathological features are similar to Periapical Cemento-Osseous Dysplasia

Treatment:

Other: The data of patients who had applied to the clinic for various reasons and were diagnosed with fibro-osseous lesions

Grup 3. Florid Cemento-Osseous Dysplasia

Description:

When the lesions involve two or more quadrants of the jaw, it is defined as Florid Cemento-Osseous Dysplasia. Its radiographic and histolopathological features are similar to Periapical Cemento-Osseous Dysplasia

Treatment:

Other: The data of patients who had applied to the clinic for various reasons and were diagnosed with fibro-osseous lesions
