Fibro-osseous oral

Megan Sullivan, George Gallagher, Vikki Noonan
BACKGROUND: A preponderance of periapical radiolucencies are of inflammatory etiology (radicular cysts or periapical granulomas) secondary to pulpal disease. In some instances, however, a suspected periapical inflammatory lesion is not a consequence of pulpal disease but instead represents a lesion of noninflammatory origin. The differential diagnosis for such lesions is broad, ranging from odontogenic cysts and tumors to metastatic disease. As the biological behavior of such lesions is varied, the distinction between inflammatory odontogenic periapical lesions and lesions of noninflammatory origin in a periapical location is critical...

Florid cemento-osseous dysplasia (FCOD) belongs to the group of fibro-osseous lesions in which normal bone is replaced by fibrous connective tissue and calcified cementum tissue of the avascular type. Among the various types of fibro-osseous lesions, FCOD is one of the most commonly encountered diseases in clinical practice and may involve 3 or 4 of the quadrants. FCOD is located in the periapical regions of teeth, and the lesions are predominantly radiolucent (osteolytic phase), become mixed over time (cementoblast phase), and ultimately become radiopaque (osteogenic phase) with a thin radiolucent peripheral halo...

Fibrous dysplasia is a non-neoplastic hamartomatous developmental fibro-osseous lesion of bone. Monostotic fibrous dysplasia is more common than the polyostotic form and usually involves jaw bones, ribs and femur. Maxillary lesions may extend to involve the maxillary sinus, zygoma, sphenoid bone and floor of the orbit and require surgical intervention resulting in an acquired defect of the involved site. A multidisciplinary team approach involving an oral pathologist, oral surgeon, oral medicine expert and maxillofacial prosthodontist is required for successful treatment and rehabilitation of such patients...

INTRODUCTION: Fibro-osseous lesions of the skull and facial bones are benign tumors, but they can be mistaken for malignant tumors due to their clinically aggressive behavior. Cemento-ossifying fibroma (COF) is a benign fibro-osseous lesion characterized by slow growth and fibrous and calcified tissue content. COFs are locally destructive lesions causing deformities in the bones. The recurrence risk is high if they are not completely removed. CASE REPORT: In this case report we describe a giant COF mimicking chondrosarcoma in the oral cavity of a 55-year-old woman causing significant facial deformity and feeding problems...

Ossifying fibroma (OF) and fibrous dysplasia (FD) are benign, intraosseous, proliferative fibro-osseous lesions (PFOLs) characterized by replacement of normal bone by a fibrous matrix with various degrees of mineralization and ossification. Osteomas are benign tumors composed of mature, well-differentiated bone. Clinical, imaging, and histologic features of 15 initially diagnosed benign PFOLs and osteomas of the canine oral cavity were evaluated. Final diagnoses after reevaluation were as follows: OF (3 cases), FD (4 cases), low-grade osteosarcoma (LG-OSA) (3 cases), and osteoma (5 cases)...

Cemento-ossifying fibroma (COF) is a benign fibro osseous lesion of the jaws which has been described as a demarcated or rarely encapsulated neoplasm consisting of fibrous tissue and varying amounts of mineralized material resembling bone and/or cementum (Dinkar et al. in IJDA 2(4):45-47, 2010). Majority of lesions occur in the mandible and only few cases of COFs of the maxillary sinus and bilateral COFs of the mandible have been reported in literature (Dinkar et al. in IJDA 2(4):45-47, 2010; Tamiolakis et al...

Central ossifying fibroma (COF) is a rare benign fibro-osseous neoplasm which has a predilection for mandible and is encountered in middle aged women. It arises from mesenchymal blast cells of the periodontal ligament, and with a potential to form fibrous tissue, cementum and bone. It is a well circumscribed lesion mainly comprising of fibrous tissue with varying amounts of bone or cementum or osteo-cementum like tissue. We present an uncommon case of COF of the maxilla in a 35-year-old male who presented with a pus discharging sinus in the maxilla...

Fibrous dysplasia (FD) as an abnormal bone growth is one of the common fibro-osseous leasions (FOL) in oral and maxillofacial region, however, its etiology still remains unclear. Here, we performed gene expression profiling of FD using microarray analysis to explore the key molecule events in FD development, and develop potential diagnostic markers or therapeutic targets for FD. We found that 1,881 genes exhibited differential expression with more than two-fold changes in FD compared to normal bone tissues, including 1,200 upregulated genes and 681 downregulated genes...

Traumatic temporomandibular joint (TMJ) ankylosis can be classified into fibrous, fibro-osseous and bony ankylosis. It is still a huge challenge for oral and maxillofacial surgeons due to the technical difficulty and high incidence of recurrence. The poor outcome of disease may be partially attributed to the limited understanding of its pathogenesis. The purpose of this article was to comprehensively review the literature and summarise results from both human and animal studies related to the genesis of TMJ ankylosis...

An osteolytic lesion with a small central area of mineralization and sclerotic borders was discovered incidentally in the clivus on the cone-beam computed tomography (CBCT) of a 27-year-old male patient. This benign appearance indicated a primary differential diagnosis of non-aggressive lesions such as fibro-osseous lesions and arrested pneumatization. Further, on magnetic resonance imaging (MRI), the lesion showed a homogenously low T1 signal intensity with mild internal enhancement after post-gadolinium and a heterogeneous T2 signal intensity...

Central ossifying fibroma is a rare, benign fibro-osseous lesion that arises from the periodontal ligament. Periapical cemento-osseous dysplasia is another variant of fibro-osseous lesion which occurs in the anterior region of the mandible of females. Odontoma is a benign odontogenic tumor that contains enamel, dentine cement and pulp tissue. A 46-year-old woman was referred to the Department of Oral Medicine, School of Dentistry, Tehran University of Medical Sciences, with two non-painful swellings on both sides of the mandible, which had been slowly growing over a period of one year...

The canonical Wnt/β-catenin pathway is involved in the formation of craniofacial skeleton and oral tissues. Aberrant nuclear localization of β-catenin protein has been described in several human diseases including a subset of odontogenic tumors thereby suggesting an important role in tumor development. Fibro-osseous lesions of the craniofacial skeleton comprise several neoplastic, and reactive mesenchymal proliferations in which β-catenin status is unknown. To study this, we immunostained 171 fibro-osseous lesions for β-catenin protein and, for lesions with nuclear positivity, sequenced exon 3 of the CTNNB1 gene and exon 15 of the APC gene...

Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unless pulpal or periodontal infection supervenes. Radiographic features of lesions vary from well-delineated to irregularly bordered mottled radiolucencies, and these can be confused with dental caries...
