1/104. Imaging of a Stafne bone cavity: what MR adds and why a new name is needed.

    Stafne bone cavities are asymptomatic radiolucencies seen at the angle of the mandible. Although plain films are often sufficient for diagnosis, confirmatory imaging is needed in atypical cases. We describe the MR imaging findings of a Stafne bone cavity, describe the contents, explain why a new name is needed, and discuss the relative merits of different radiologic techniques for establishing this diagnosis.

2/104. Spontaneous uprighting of permanent tooth germs after elimination of local eruption obstacles.

    Four clinical cases are presented to demonstrate the self-correcting potential of aberrant tooth germs after the elimination of eruption obstacles (in 2 cases cysts, in 2 other cases severely infraoccluded primary teeth). In the case of the submerging deciduous teeth, the tilted adjacent teeth were orthodontically uprighted after the surgical procedure. Possible causative mechanisms are discussed. ( info)

3/104. So-called simple bone cyst of the jaw: a family of pseudocysts of diverse nature and etiology.

    The nature and etiology of so-called simple bone cyst (SBC) are still a subject of debate. Our comprehensive review of the literature suggests that SBC, which appears histologically to be a single entity, has different natures and etiologies, resulting in divergent clinical features. In addition, an interesting case of mandibular SBC in an 11-year-old girl is presented with details of radiographic changes over a 7-year period. Fully documented patient records revealed that this lesion originated in the apical area of the first molar and took about 4 years to develop into a clinically evident bony expansion. ( info)

4/104. Implantation-type epidermoid cyst of the mandible.

    The documented cases of epidermoid implantation cysts affecting the oral tissues are reviewed. A unique case involving the ramus of the mandible is presented. ( info)

5/104. Traumatic bone cyst--a case report.

    Traumatic bone cyst is an asymptomatic, slow growing, non expansile lesion commonly diagnosed during routine radiographic examination of the jaw bones. It is more frequently seen in young age, with predilection for anterior region of the mandible leading to a dramatic healing of the lesion. A typical case of traumatic bone cyst in a 12 year old girl is reported. A routine radiologic assessment of the patient with panoramic radiograph revealed a fairly large lesion in the anterior region of the mandible. On surgical exploration, clinical diagnosis was confirmed. Post operative successive radiograph shows progressive osseous healing. ( info)

6/104. Postoperative maxillary cyst following sinus bone graft: report of a case.

    Sinus bone grafting with autogenous bone is routinely performed to allow placement of endosseous dental implants. Although numerous maxillary sinuses have been successfully grafted, some complications of this procedure have been reported. These include maxillary sinusitis, resorption, infection and possible failure of grafts, loss of implants after 1-stage surgery, and oroantral fistulae. Only one case of postoperative maxillary cyst developing in the graft has been reported in the literature. Here, the authors report a similar case that necessitated grafting of the cyst with autologous iliac bone. ( info)

7/104. A patient whose cerebral aneurysm ruptured soon after an operation to remove a maxillary cyst.

    A hypertensive woman complained of a headache soon after an operation to remove a maxillary cyst. A computed tomogram showed evidence of subarachnoid haemorrhage and on angiogram an aneurysm of an anterior cerebral artery. The aneurysm was treated by clipping and the patient recovered. ( info)

8/104. The lateral periodontal cyst: aetiology, clinical significance and diagnosis.

    The lateral periodontal cyst (LPC) is a relatively uncommon but widely recognized odontogenic cyst of developmental origin. It is found mostly in adults and has no sex predilection. LPC is usually discovered during routine radiographic examination, is located mainly between the roots of vital mandibular canines and premolars, and seldom causes pain or other clinical symptoms. The defect appears on radiographs as a round or teardrop-shaped, well circumscribed radiolucency. Due to its location it can easily be misdiagnosed as a lesion of endodontic origin. In this paper, two cases of lateral periodontal cysts are presented. In the first case, the patient (woman, 62 years old) complained of an asymptomatic gingival swelling in the region between the right maxillary canine and premolar. The radiographic examination revealed a well circumscribed radiolucency with a radiopaque margin between the roots of the canine and premolar. The adjacent teeth had vital pulp. Surgical enucleation of the lesion was performed and the histological examination revealed that the lesion was a "lateral periodontal cyst of developmental origin". In the second case, the patient (women, 44 years old) complained of a swelling in the area of tooth 32. During radiographic examination a well circumscribed radiolucency between the roots of the lateral incisor and the canine was discovered. Surgical enucleation of the lesion was performed and the histological examination revealed that the lesion was a "lateral periodontal cyst of developmental origin". ( info)

9/104. Multiple Stafne bone cavities: a diagnostic dilemma.

    Salivary gland inclusions in the mandible are relatively uncommon. If defects occur they are generally unilateral, although bilateral cases have been reported. This article describes an unusual case in which the dental panoramic tomogram revealed three radiolucent areas in the mandible. The diagnosis of the two posterior radiolucencies was confirmed as Stafne's bone cavities but a definite diagnosis for the parasymphyseal lesion remained elusive, even after surgery. However, Stafne's bone cavities are known to occur in this region and this diagnosis remains the most probable. ( info)

10/104. Stafne's bone cavity in the anterior mandible: a possible diagnostic challenge.

    Stafne was the first to report the presence of "bone cavities" in the angle of 35 mandibles. Such cavities generally appear in the area between the mandibular first molar and the mandibular angle, and are not considered rare. One of their primary radiological diagnostic features is the characteristic location below the mandibular canal. Stafne's bone cavity is relatively rare in the anterior mandible. The mandibular canal is not present in the anterior mandible. As a result, diagnosis in the anterior mandible may be missed. Needless treatment modalities such as endodontic treatment, bone trephining, and bone exploration may be conducted. The purpose of the present report is to describe a new case of Stafne's bone cavity in the anterior mandible and discuss the differential diagnosis process. The dental computerized tomography scan is suggested as the most suitable noninvasive diagnostic and follow-up modality for this bony configuration in the anterior mandible. ( info)
