Cemento osseous dysplasia pdf
The presenting features of the patient and the effect of orthodontic treatment on this case are discussed. Osseous dysplasias are a group of idiopathic processes located in the tooth-bearing areas characterized by replacement of normal bone by fibrous tissue and metaplastic bone When osseous dysplasias occur bilaterally in the mandible or even involving all jaw quadrants, the condition was termed as florid osseous dysplasia (FOD) and was first described by Melrose et al . Florid cemento-osseous dysplasia may have similarities with jaw bone changes in familial adenomatosis coli (Gardner’s syndrome)(15), but florid cemento-osseous dysplasia has no other skeletal changes or skin tumours or even the dental anomalies that are seen in this syndrome.
Cemento-osseous dysplasia (COD) is a cementum or bone producing fibro-osseous lesion confined to the tooth-bearing regions of the jaws. Florid cemento-osseous dysplasia (FLCOD) is the most dramatic and rare variant of the cemento-osseous lesions. The age group may vary from 19 to 76 years and typically presents in the 4th and 5th decades.
The word ‘florid’ was introduced to describe the wide spread, extensive manifestations of the disease in the jaws. It has a variable radiographic appearance depending on the phase at which it is diagnosed. COD has a sexual and racial predilection, with women of African or southeastern Asian descent being most frequently affected, and the mean age at diagnosis is between 30 and 50 years. Osseous (Cemento-osseous) Dysplasia of the Jaws: Clinical and Radiographic Analysis | jcda.
It arises due to the superseding of bone to fibrous connective tissue.
As in any other surgical procedure, including biopsy, implant placement might open up the doors to bacteria access to the bone environment. Here we present such a rare case occurring in a 37 year old female who came with a swelling and dull pain in the lower right back teeth region since 1 and 1/2 years. The histopathology, in conjunction with the surgical findings and radiography were consistent with a diagnosis of a simple bone cyst with concomitant cemento-osseous dysplasia. This lesion is a rare benign fibro-osseous condition of bone, the cause of this disorder is unknown [1–3]. The diagnostic dilemma faced is that of benign fibro-osseous lesions, A partial list of entities encompassed by this term includes fibrous dysplasia, cherubism, ossifying and cementifying fibroma, Paget's disease, and cemento-osseous dyaplasia. It is a rare condition presenting in the jaw refers to a group of fibro-osseous (cemental) exuberant lesions with multi-quadrant involvement.
Bone dysplasias comprise of a condition where the normal bone is replaced with fibrous tissue. Radiographically, the lesions appear as multiple sclerotic masses in the tooth-bearing regions which usually affect the mandible on both sides in a symmetrical manner, but all four quadrants may be involved, it presents as multiple radiopaque lesions that fuse into lobulated sclerotic masses. In most cases patients do not have hereditary basis of disease, and only a few familial cases have been documented. Abstract Introduction Florid cemento-osseous dysplasia is one of the terms that have been designated by the World Health Organization as cemento-osseous dysplasias of the jaws. Florid cemento-osseous dysplasia is the term used when large exuberant radiopaque masses are identified, quite often in all quadrants of the jaws (Figure 4b).
Florid cemento-osseous dysplasia: review of an uncommon fibro-osseous lesion of the jaw with important clinical implications. Unfortunately, these lesions are usually diagnosed through routine radiographic examination.
Florid cemento osseous dysplasia: 15-years clinical and radiographic follow-up RH Dababneh1* Abstract Introduction Florid cemento-osseous dysplasia is one of the terms that have been designated by the World Health Organization as cemento-osseous dysplasias of the jaws. Cemento-osseous dysplasia (COD) is a group of disorders involving benign fibro-osseous lesions of bone. This classification based on clinical characteristic, location and radiographic features [2,4]. Florid cemento-osseous dysplasia is one of the terms that have been designated by the World Health Organization as cemento-osseous. PDF | Familial gigantiform cementoma is an exceedingly rare but distinct subtype of cemento-osseous-fibrous lesion. The present case was unusual due to the involvement of maxillary posterior region in a young female which presented as bony enlargement.
COD has a sexual and racial predilection, with women of Afri-can or southeastern Asian descent being most frequently affected, and the mean age at diagnosis is between 30 and 50 years. It usually exhibits as multiple radiopaque cemetum-like masses distributed throughout the jaws.
The term florid cement-osseous osseous dysplasia (FCOD) was first suggested by Melrose et al in 1976 to describe a condition of exuberant multi quadrant masses of cementura and/or bone in both jaws and in some cases, simple bone cavity like lesions in affected quadrant .The word 'florid' was introduced to describe the wide spread, extensive manifestations of the disease in the jaws. However, the World Health Organization's most recent tumor classification says that periapical cemento-osseous dysplasia is a condition related to osseous lesions 2 . The Management of florid cemento-osseous dysplasia for asymptomatic patients consist of regular recalls and observations to ensure that the process is confined within normal limits of the disease and to detect any possible changes, as the disease may persist for indefinite periods of time without causing any symptoms. We report two cases of cemento-ossifying fibroma (COF) and review the literature in order to study the imaging findings of COF. Clinically, most of the Osseous dysplasias (ODs) are asymptomatic and are accidently discovered during routine radiographic examinations.
Cemento-osseous dysplasia is the most common fibroosseous lesion affecting the jaw bones. caution was taken during the surgical procedure as florid cemento-osseous dysplasia is associated with hypo-vascularity of the affected bone. Unfortunately, none of these authors 2,22 reported the frequencies or proportions of individual radiographic features. Radiographic examination plays an important role in the diagnosis of FCOD, especially in asymptomatic cases as biopsy increases the risk of infection and fracture. These tissues lack normal cellular components and contain fibrous connective tissues. However, some authors 2 found that it may be an initial form of florid cemento-osseous dysplasia.
Cemento-osseous Dysplasia (Florid) Florid cemento-osseous dysplasia is characterized as a benign fibro-osseous lesion that replaces the normal bony tissues with poorly formed cementum-like tissues through a reactive process. cemento-osseous dysplasia: report of a case documented with computed tomography and 3D imaging. The purpose of this paper is to report three cases diagnosed as FCOD with their clinical, radiographic and histological findings. One such fibro-osseous lesion is cemento-osseous dysplasia (COD), a group of non-neoplastic processes usually confined to the tooth-bearing areas of the jaws or edentulous alveolar processes. Due to the potential risk of introducing an infection, biopsy of an asymptomatic lesion is contra-indicated and it is therefore mandatory to establish an accurate diagnosis only on clinical and radiological information. the most important thing for you is to find a website where you can download pdf files for free. Osseous (Cemento-osseous) Dysplasia of the Jaws: Clinical and Radiographic Analysis.
Cemento-osseous Dysplasia : Report of 3 Cases and Review of the Literature I v o h . Patients usually present with diffuse swellings, discharging sinuses/fistulae or osseous sequestra.
In this paper, we present and discuss a case of a patient with COD in which a dental implant had been installed but lost six months after surgery. Cemento-osseous dysplasia (COD) is a benign condition of the jaws that may arise from the fibroblasts of the periodontal ligaments.
Diagnosis was established on the basis of persistence of swelling, as well as radiographic and microscopic appearance. Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women.
Florid cemento osseous dysplasia: Chronic diffuse sclerosing osteomyelitis is not confined to tooth-bearing areas; it is a primary xemento-osseous condition of the mandible, with cyclic episodes of unilateral pain and swelling. Like PCOD, most cases of focal COD occur in middle-aged women, but more frequently in whites. Lesions classified as Cemento-osseous dysplasia (COD) largely encompass three different sub-groups: Florid, focal and periapical lesions. Odontogenic myxomas are characterized by lytic osseous changes of varying size, which may be demarcated and expansile or exhibit ill-de-fined borders.
This condition affects mostly mandibular anterior region and rarely occurs in the maxilla. A simple bone cyst (SBC) is an intrabone cavity without epithelial lining, which occasionally occur with fibrous-osseous lesions. A benign, asymptomatic condition affecting the development of the periapical tissues. Background: Cemento-Ossifying Fibroma (COF) is considered by most as relatively rare, benign, non-odontogenic neoplasm of the jaw bones and other. A healthy 26‐year‐old white female was referred to the Wilford Hall USAF Medical Center Endodontic Department for evaluation of an asymptomatic radiolucency at the apex of the right mandibular lateral incisor. cemento-osseous dysplasia.11, 12 However, the authors describe demographic, clinical, radiographic and histological features similar, if not identical, to periapical cemento-osseous dysplasia and concluded that periapical COD and focal COD are the same process. Although the two lesions are indistinguishable under imaging and microscopic examination, familial gigantiform cementomas displasai a familial or hereditary history, whereas florid cemento-osseous dysplasia does not.
The treatment of these lesions, once diagnosed by radiology, is not required because generally they are asymptomatic. Normal bone architecture is replaced by fibroblasts and collagen fibres with varying amounts of mineralised material.
We report a case of FCOD of mandible in a year-old female.
Advanced imaging was performed in cases where conventional radiographs did not suggest the definitive diagnosis, in cases where a simple bone cyst was identified and those in which gocal was suspected. Familial florid cemento-osseous dysplasia: Under normal conditions, these cells differentiate into cementoblasts, fibroblasts and osteoblasts of the alveolar bone every day. Clinical, demographic, and radiographic analysis of 82 patients affected by florid osseous dysplasia: This report will present “according to our knowledge” the first documented case of FCOD in Jordan with 15 years clinical and radiographical data follow up. Background: Cemento-osseous dysplasia is a benign fibro-osseous lesion of the tooth-bearing region of the jaws with a periodontal ligament origin. All books are in clear copy here, and all files are secure so don't worry about it. The appearances of such extensive dense and radiological masses of sclerotic bone may suggest a diagnosis of Paget's disease but these patients have normal blood chemistry and extra-gnathic lesions are absent.
Periapical cemento-osseous dysplasia is a self-limiting problem because the osseous cortex is not expanded and progressive growth is rare. Cervicofacial actinomycosis is an uncommon and progressive infection caused by bacilli of the Actinomyces genus that typically involves intraoral soft tissues but may also involve bone.
The characteristics described above indicate that orthodontists must make an accurate diagnosis of florid cemento-osseous dysplasia in the analyses conducted for their treatment planning, as this disease, when fully established, is one of the rare conditions that contraindicate orthodontic treatment. Florid cemento-osseous dysplasia: review of an uncommon ﬁbro-osseous lesion of the jaw with important clinical implications. Cemento –osseous dysplasia In 1992 by the World Health Organization classified cemento-osseous dysplasia , based on age, sex and histopathologic, radiographic and clinical characteristics, as well as location of the lesion. Its importance is that it could mimic a periapical lesion in the early, translucent stage. Periapical cemento-osseous dysplasia typically arises in the anterior mandible and involves one or only a few teeth. Osseous dysplasia lacks encapsulation or demarcation,but tends to merge with the adjacent cortical or medullary bone. Report of a case documented with clinical, radiographic, biochemical and histological findings. 1-5 FD lesions occurring in the jawbones may be histologically distinctive, but also may exhibit features shared by other less well‐defined entities such as ossifying or cemento‐ossifying fibromas.
This lesion occurs more frequently in Black and Asians.
The extraoral examination showed a facial asymmetry due to the swelling of the left mandibular area Fig. Once the occlusion adjustment was performed, patient returned without complaints. However, cemebto condition affects the bone of the entire mandible and shows ossda of lamina dura, whereas florid cemento-osseous dysplasia is centered above the inferior alveolar canal and its cervical two thirds are normal The occlusal images revealed slight buccal expansion at the molar region on the right side of the mandible Fig. Abstract: Florid cemento-osseous dysplasia represents one of the few clinical contraindications to osseointegrated implant placement. PDF | Florid cemento-osseous dysplasia is a subtype of fibrous-osseous lesion that commonly appears in the jaws of middle-aged black women. Osseous dysplasia (Cemento-osseous dysplasias) is relatively common form of fibro osseous lesions (FOLs) in the tooth-bearing regions of the jaw bones. Discussion : The lesions are most frequently seen in middle-aged black women and show a marked tendency for bilateral and symmetric involvement.
