The aim of this study is to present a case of periapical cemento-osseous dysplasia. Periapical cemento-osseous dysplasia is a self-limiting problem because the osseous cortex is not expanded and progressive growth is rare. She brought a panoramic radiograph taken after surgery that showed the presence of a dental implant in the region of tooth 25, surrounded by an inconspicuous radiolucency Figure 1.

According displasai the stimuli applied to its ozsea, the form and volume that define bone design may be remodeled.

This overlapping reveals that these radiopaque and radiolucent masses are random in a variety of radiographic images.

The reactional and reparative capacity of bone osse florid cemento-osseous dysplasia is severely limited. Familial florid cemento-osseous dysplasia: Patient returned 12 months later and the lesion still preserved its radiolucent aspect with increase of internal radiopacity. J Dent Assoc S Afr ; How to cite this article. There are few and very small medullary spaces. New panoramic and periapical radiographs confirmed the same osseous alteration as described above.

Mandible’s periapical area is the most common site of appearance; frequently multiple sites are affected root apex of two or more teeth. Densely mineralized and disorganized bone is unable to remodel or develop in an organized way in the periodontal ligaments and the alveolar process.

She was systemically healthy and extra-oral examination was within normal limits.

When such process occurs in the periapical area of mandible’s anterior teeth, is so-called periapical cemento-osseous dysplasia. In a certain point of the region of the mandibular molars and premolars, probably simultaneously in both sides, bone tissue is resorbed and replaced with fusiform and polyhedral cells that form discretely fibrosed connective tissue. Maxilla was not affected; implant is normal and functioning.

Unusual behavior of periapical cementous dysplasia. The diseased bone is partially mineralized with a peripheral strip of osteoid matrix arrowhead. These findings, together with pssea qualities found in the imaging analysis, were considered diagnostic for the florid variant of COD FCOD.

Florid cemento-osseous dysplasia: a contraindication to orthodontic treatment in compromised areas

Florid cemento-osseous dysplasia probably originates in the periodontal ligament as a result of irregular cementum formation and a disorder in the differentiation of periodontal ligament stem cells. Osteomyelitis occur only in: These aspects characterized the cementoblastic ceemnto of the development.

Multiple sclerotic masses with radiolucent border in the mandible were identified radiographically.

Cmento histomorphological findings of periapical, focal and florid dysplasias are essentially undistinguishable and show a spectrum of progressive features depending on, especially, the stage of the lesions’ development. Florid cemento- osseous dysplasia: Osseointegrated dental implants have been routinely used in oral rehabilitation. The cases of periapical cemento-osseous dysplasia are often detected through routine radiographic examinations Dieplasia clinical oseea, it could be noted the presence of caries lesions, gingival retraction, periodontal pocket at tooth 17 and a nodular lesion in lower lip whose diagnosis was fibrous hyperplasia.

On the other hand, looking at the second part of the question, the concept of apparently normal bone that is likely to develop dysplastic lesions leads to a highly unstable tissue environment that makes the dynamics of bone healing an unpredictable phenomenon. Systemic and local factors that affect bone tissue, such as the presence of endocrine disorders diabetes mellitus, hyperparathyroidism, hypothyroidism and osteoporosiscysts, tumors, radiation therapy, and bone dysplasia are relevant in planning oral rehabilitation with implants 1.

They concluded that the clinical entity called focal cemento-osseous dysplasia was an initial phase of florid cemento-osseous dysplasia that gradually compromises the other areas to result in the complete or generalized symptoms of the disease.

In that first study, six lesions were defined, four of which were classified in a group called issea Another disease that may resemble the florid cemento-osseous dysplasia is chronic diffuse sclerosing osteomyelitis. Thus, we suggest that COD should be seen as a limiting factor in the recommendation of oossea implants and it is imperative to inform the patient about the risks associated with this disease. Mandibular lesions are mixed, some radiopaque, some radiolucent, and are confused with djsplasia of molar teeth, as they are randomly distributed in posterior region.

Periapical cemento-osseous dysplasias are probably the most common fibro-osseous lesions found in clinical practice. The case here described, due to its radiographic aspect, probably was at cementoblastic stage, which is characterized by a variable amount of mineralized tissue comprising immature bone trabeculae and round drops of a tissue similar to cementum.

Differences between florid osseous dysplasia and chronic diffuse sclerosing osteomyelitis. In this regard, we analyzed pertinent aspects of the indications for dental implants in patients with COD considering the pathogenesis, dysplastic nature, and behavior of the disease. The patient was asked if she was aware of the existence of some type of alteration in that area, which she denied, indicating that she was absolutely unaware of the disease.

Failure of dental implants in cemento-osseous dysplasia: a critical analysis of a case

Periapical cemental dysplasia in twin sisters: In these initial displasiaa, there are no clinical signs, not even any signs on CT scans or radiographs Figs 1 to 4. At the initial stages, the lesions are represented by a fibrous non-encapsulated conjunctive tissue exhibiting numerous blood vessels of small caliber and lack of inflammatory cells 4.

Defining a uniform nomenclature and classification of these lesions is difficult because it is impossible to distinguish whether the mineralized material in these lesions is cement or bone, even when analyzed under transmission or scanning electron microscopy or immunocytochemistry.

It is a consensus that the execution of invasive procedures, such as tooth extraction and biopsy for histopathological analysis in periapical cemento-osseous dysplasia patients is extremely contraindicated. However, the need to use the term gigantiform cementoma oasea familial gigantiform cementoma was demonstrated by Young et al 9 inwho described five generations of a family with familial gigantiform cementoma of dominant autosomal character.

A 50 years-old female patient sought for dental displasiw due to pain in the lower right premolar region. Florid cemento-osseous dysplasia and chronic diffuse osteomyelitis: Dentin formation in so-called fibro-osteo-cemental lesions of the jaw: In this report, the implants were installed in an area of supposedly “normal bone,” because no consideration about the local bone conditions had been made.

It appears as a single, poorly delineated opaque segment of the mandible, whereas florid cemento-osseous dysplasia is seen as multiple round or lobulated opaque masses. World Health Organization; J Oral Maxillofac Pathol.
