Periapical cemento-osseous dysplasia (COD) is a very rare benign lesion arising from a group of disorders which are known to originate from undifferentiated. Lesions classified as Cemento-osseous dysplasia (COD) largely encompass three different sub-groups: Florid, focal and periapical lesions. Presentation is said. Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments. It is most common in.

Sclerotic cemental masses of the jaws so-called chronic sclerosing osteomyelitis, sclerosing osteitis, multiple enostosis, and gigantiform cementoma. In their early stages, lesions may be misidentified as a form of periapical rarefying osteitis, for example as a periapical abscess, granuloma, or cyst, and in these cases unnecessary endodontic treatment may be performed Clinical and radiographic features are diagnostic for FCOD, it is almost always asymptomatic and nonexpanding, usually discovered incidentally on routine dental radiographs.

Periapical cemento-osseous dysplasia: clinicopathological features.

Diagnosis is important so that the treating doctor does not confuse it for another periapical disease such as rarefying osteitis or condensing osteitis. Consent Written informed consent was obtained from the patient for publication of this case report and accompanying images. The symmetrical radiolucency was remarkably reduced as more mineralization occurs at whole mandibular associated lesions. The affected lesion of the mandible exhibits a diffuse opacity with poorly-defined borders Due to the persistence of swelling and slight pain post-extraction, a cone-beam computed tomographic scan was taken; this showed a mixed radiotransparent and radio-opaque lesion in the area of the extracted teeth.

Competing interests None declared. In the current study, occlusal radiographs were not available for all cases, and bony expansion could not be comprehensively analyzed. The remaining teeth in the adjacent region had meanwhile fractured. This evolution may take months or years, and during its development, the diameter of the lesion increases from 0. Of these patients, most 97 [ Histological examination revealed multiple small fragments of cementum-like substances characterized by islands of calcified deposits and areas of loose fibrocollagenous stroma Figure 3 ; the latter showed evidence of proliferation.


Periapical Cemento-osseous Dysplasia: Clinicopathological Features

Views Read Edit View history. The maxillary left first molar was symptomless.

The remaining patients Am J Clin Pathol Suppl: The lesion can be seen opposite the mandibular left first molar in a standard occlusal radiograph of the mandible c and a transverse computed tomography image d. The latest OPG dtsplasia as revealed in Figure 4 demonstrates similar features with an increased density in comparison to earlier stages of the disease. Cemento-osseous dysplasia with associated simple bone cysts. Abstract Introduction Florid cemento-osseous dysplasia is one of the terms that have been designated by the World Vemento Organization as cemento-osseous dysplasias of the jaws.

Periapical cemento-osseous dysplasia: clinicopathological features.

Minor radiolucency could be recognized around the roots while the high dense deposit within the bone is obvious at the mandibular associated lesions. Figure 2 shows the OPT in which revealed the same symmetrical bilateral sclerotic masses in the mandible but with increasing of the radio-opacity in comparison with the OPT in In the first or osteolytic phase, a circular radiolucent lesion is visible at the apex of the root; in the second or cementoblastic stage, cementoblastic activity increases and, consequently, spicules of cement begin to form, so that the radiolucent lesion assumes a mixed appearance.

We present a rare case of mandibular PCOD in a woman of 55 years, who presented with moderate swelling and mobility of teeth Gigantiform cementoma affecting a Caucasian family.


Histological appearance of FCOD showed large sheets or fused globules of cemento-osseous tissue, which may be fused to the roots of one or more teeth or may lay separately. The favoured conservative approach to managing these conditions involves clinical and radiologic follow-up.

Essentially, these dysplasiw disorders all involve the same pathological process. At the month checkup, a computed tomographic scan showed the lesion was unchanged in size. Focal cemento-osseous dysplasia involving a mandibular lateral incisor.

Florid cemento osseous dysplasia: years clinical and radiographic Dentistry

The long-term follow-up 15 years shows the different stages of maturation of the lesions and confirms that the condition is self-limited. For all but 3 of the patients, clinical features had been recorded.

Radiologically, the appearance of the lesion thus depends on the moment of observation. Depending on the patient’s preference, a mandibular overdenture could later be provided.

The majority of patients in the current study E-mail The content of this field is kept private and will not be osssous publicly. Ddysplasia apparent lesions presented with jaw swelling, dull pain or sensitivity, and drainage, which may have been due to secondary infection caused by direct exposure of the calcified masses to the oral cavity. A definitive diagnosis of COD was established by means of histopathological examination combined with the radiographic findings, which showed multiple radiolucent and radiopaque lesions in the mandibular teeth.

Treatment and diagnosis [ edit ] There is no treatment necessary for any type of COD.

The patient entered a six-monthly follow-up program, later reduced to annual checkups.
