1/28. Florid osseous dysplasia of the mandible: report of a case.In 1986, a 60-year-old African American woman visited the Marquette University School of dentistry with a complaint of a vague, dull pain in her lower left quadrant. tooth No. 19 was extracted 10 years earlier because of extensive decay, and tooth No. 18 had received root canal therapy. A panoramic radiograph revealed the presence of ill-defined, multilocular, mixed (radiopaque-radiolucent) lesions present throughout the lower jaw. She was treated with antibiotics and scheduled for follow-up visits. When the symptoms persisted, tooth No. 18 was re-treated with root canal therapy and a representative biopsy was taken from the left mandibular area. The biopsy showed the presence of chronic osteomyelitis. The patient was treated with antibiotics and was scheduled for periodic check-up visits. In February 1995, she returned with the same symptoms in the left mandible. A panoramic radiograph showed persistence of the mixed radiopaque-radiolucent lesions throughout her mandible; however, the mass on the left side was more radiopaque and had assumed a "cotton wool" appearance. tooth No. 18 was extracted and a biopsy was taken from the area. After correlating the clinical behavior, radiographic appearance, and histopathologic features, a diagnosis of florid osseous dysplasia with osteitis was made. This case represents a classic example of the difficulty in diagnosing fibro-osseous lesions using radiographic interpretation alone and the need to correlate the clinical, radiographic, and histopathologic features to reach a diagnosis. Additionally, the present case clearly shows treatment problems of an otherwise self-limiting condition when secondary involvement with osteomyelitis is also present. A brief description of the conditions that were included in the differential diagnosis and their management is presented.- - - - - - - - - - ranking = 1keywords = lower jaw, mandible, jaw (Clic here for more details about this article) |
2/28. Developing cementoblastoma: case report and update of differential diagnosis.The benign cementoblastoma is a rare odontogenic tumor that tends to occur in the jaws of young people. It is most commonly characterized as a circumscribed radiopaque mass attached to the tooth roots and rimmed by a thin radiolucent zone. Early lesions, however, are radiolucent and can be confused with periapical conditions resulting from nonvital teeth. The tumor is seldom recognized until it produces pain or expansion of the jaw. If the diagnosis is established early, the tooth can be saved by endodontic treatment followed by apical root resection and surgical enucleation of the tumor. This case report documents the origin, development, and unlimited growth potential of a cementoblastoma. Radiographs taken at yearly intervals reveal an initial widening of the periodontal ligament space that grew into a 3-cm mixed radiolucent and radiopaque tumor over a 4-year period. The differential diagnosis and some criteria to help distinguish the cementoblastoma from similar-appearing lesions are reviewed.- - - - - - - - - - ranking = 0.0050256303997254keywords = jaw (Clic here for more details about this article) |
3/28. Gigantiform cementoma: clinicopathologic presentation of 3 cases.Gigantiform cementoma is a rare, benign fibro-cemento-osseous disease of the jaws, seen most frequently in young girls. Radiographically, it typically presents as multiquadrant, expansile, mixed radiolucent-opaque lesions that cross the midlines of the jaws. Although cases with a familial pattern are noted in a few publications, sporadic cases have been reported without a family history. The term gigantiform cementoma has been used interchangeably with designations of other fibro-osseous entities, yet its application should be restricted by the criteria defined herein. In this article, we report 3 cases of gigantiform cementoma. Clinical, radiographic, and microscopic features of these lesions are presented, along with criteria to differentiate gigantiform cementoma from other fibro-osseous diseases of the jaws. A possible pathogenetic mechanism and treatment recommendations are discussed.- - - - - - - - - - ranking = 0.0075384455995881keywords = jaw (Clic here for more details about this article) |
4/28. Gnathodiaphyseal dysplasia: a syndrome of fibro-osseous lesions of jawbones, bone fragility, and long bone bowing.We report an unusual generalized skeletal syndrome characterized by fibro-osseous lesions of the jawbones with a prominent psammomatoid body component, bone fragility, and bowing/sclerosis of tubular bones. The case fits with the emerging profile of a distinct syndrome with similarities to previously reported cases, some with an autosomal dominant inheritance and others sporadic. We suggest that the syndrome be named gnathodiaphyseal dysplasia. The patient had been diagnosed previously with polyostotic fibrous dysplasia (PFD) elsewhere, but further clinical evaluation, histopathological study, and mutation analysis excluded this diagnosis. In addition to providing a novel observation of an as yet poorly characterized syndrome, the case illustrates the need for stringent diagnostic criteria for FD. The jaw lesions showed fibro-osseous features with the histopathological characteristics of cemento-ossifying fibroma, psammomatoid variant. This case emphasizes that the boundaries between genuine GNAS1 mutation-positive FD and other fibro-osseous lesions occurring in the jawbones should be kept sharply defined, contrary to a prevailing tendency in the literature. A detailed pathological study revealed previously unreported features of cemento-ossifying fibroma, including the participation of myofibroblasts and the occurrence of psammomatoid bodies and aberrant mineralization, within the walls of blood vessels. transplantation of stromal cells grown from the lesion into immunocompromised mice resulted in a close mimicry of the native lesion, including the sporadic formation of psammomatoid bodies, suggesting an intrinsic abnormality of bone-forming cells.- - - - - - - - - - ranking = 0.017589706399039keywords = jaw (Clic here for more details about this article) |

6/28. Surgical and prosthodontic rehabilitation for a patient with aggressive florid cemento-osseous dysplasia: a clinical report.Florid cemento-osseous dysplasia is an extensive form of periapical cemental dysplasia, which usually involves 1 to 4 posterior areas of the maxilla and mandible. The affected area undergoes changes from normal vascular bone into an avascular cementum-like lesion. The lesion is usually benign; however, treatment of a secondary infection of this lesion can be difficult and complicated. This clinical report describes a rare but aggressive secondary infection of this type, which was successfully treated by a combination of complex surgical and prosthodontic procedures, including dental implant therapy.- - - - - - - - - - ranking = 0.0033148043910895keywords = mandible (Clic here for more details about this article) |
7/28. Focal cemento-osseous dysplasia involving a mandibular lateral incisor.AIM: To report a case of focal cemento-osseous dysplasia (FCOD) affecting a single tooth misdiagnosed as an inflammatory periapical lesion.SUMMARY: The patient, a black 47-year-old woman complained of pain affecting the right side of the mandible. Routine X-ray examination discovered a periapical radiolucency on the mandibular left lateral incisor (tooth 32), which was otherwise normal and not carious. As the response of this tooth to a vitality test was doubtful, the lesion was diagnosed as a periapical granuloma or cyst secondary to pulpal necrosis. Endodontic treatment and curettage of the periapical lesion were performed, and histological examination of the curettage material revealed a localized osseous dysplasia. KEY learning POINTS: FCOD may rarely affect only one tooth, resembling a periapical granuloma or cyst. Careful diagnosis is of paramount importance in cases of questionable periapical lesions affecting normal-looking teeth, before beginning treatment. FCOD generally requires no treatment. biopsy is warranted in case of doubt.- - - - - - - - - - ranking = 0.0033148043910895keywords = mandible (Clic here for more details about this article) |
8/28. Familial gigantiform cementoma with brittle bone disease, pathologic fractures, and osteosarcoma: a possible explanation of an ancient mystery.We describe four individuals of an African-American family with a predominantly diaphyseal bone disease associated with familial gigantiform cementoma (FGC), a disorder typically seen in Caucasians. The mother and her children presented with deformities of the jaws, abnormalities of the long bones, and pre-pubertal pathologic fractures. The index patient carried the diagnosis of osteosarcoma (OS). In addition, we provide a possible explanation for the jaw abnormalities of King Tutankhamen's father in the 18th dynasty in egypt around 1350 BC.- - - - - - - - - - ranking = 0.0050256303997254keywords = jaw (Clic here for more details about this article) |
9/28. Simultaneous presentation of focal cemento-osseous dysplasia and simple bone cyst of the mandible masquerading as a multilocular radiolucency.The fibro-osseous lesions represent a large group of disorders that have many common characteristics including clinical, radiographic and microscopic features. Although most are of unknown aetiology, some are believed to be neoplastic and others are related to metabolic imbalances. It is not unusual to see these lesions presenting with a range of radiographic appearances, causing considerable diagnostic confusion owing to their similar histology. This case report presents a histologically benign cemento-osseous lesion that is radiographically consistent with a focal cemento-osseous dysplasia, along with a concomitant simple (traumatic) bone cyst within the right mandibular alveolus, with the initial presentation as a multilocular radiolucency. Pertinent literature is reviewed.- - - - - - - - - - ranking = 0.013259217564358keywords = mandible (Clic here for more details about this article) |
10/28. Benign cementoblastoma: a case report.Benign cementoblastoma is an odontogenic tumour of mesenchymal origin. It usually presents as a distinct lesion with characteristic radiographic and histopathologic features. The tumour is attached to the roots of the teeth and commonly occurs in the posterior mandible. The case of a 19-year old female with a benign cementoblastoma is presented. The clinical histopathologic and therapeutic aspects of the tumour are described.- - - - - - - - - - ranking = 0.0033148043910895keywords = mandible (Clic here for more details about this article) |
