SAPHO syndrome of the temporomandibular joint associated with trismus: a case report and review of the literature
AbstractSynovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a disorder characterized by pustular skin lesions and osteoarticular lesions. Mandibular involvement occurs in approximately 10% of the cases, and is often seen as recurrent mandibular osteitis with bone sclerosis, mainly involving the body of the mandible in the head and neck region. Middle cranial base with temporomandibular joint (TMJ) involvement in SAPHO syndrome can be diagnostically challenging because of its rarity. Herein, we present a case of a 37-year-old man who suffered from trismus and dull pain in the left TMJ region. The ini...

Malignant transformation of fibrous dysplasia into angiosarcoma
AbstractFibrous dysplasia (FD) is generally considered to be a benign disease that affects the bones, but it has potential to become malignant over time, generally several decades after its initial diagnosis. Radiation therapy can induce malignant transformation of FD; however, reports have indicated a few cases of malignant transformation of FD in the absence of radiation therapy. Angiosarcoma is a particularly rare type of cancer in the oral region, which accounts for less than 1% of all soft-tissue sarcomas. Herein, we reported a case of a 62-year-old man with monostotic FD of the left maxilla of over 50  years&rsq...

Cone-beam computed tomography imaging of dentoalveolar and mandibular fractures
AbstractThree-dimensional imaging methods have an important role in the diagnosis of dentomaxillofacial fractures that can not be seen on the plain films. Cone-beam computed tomography (CBCT) is one of the three-dimensional imaging methods and has facilitated dental professionals ’ access to cross-sectional imaging. CBCT units allow different technical parameters and the data acquired by CBCT, can be reformatted. Osseous structures are correctly examined with this technique but the technique is not useful for the examination of soft tissues. Therefore, the purpose of its u se should be based on the expected diagnosti...

Reliability of marginal bone level measurements on digital panoramic and digital intraoral radiographs
ConclusionBitewing examination should be the choice of image modality for assessment of marginal bone level at premolar region due to good to excellent reliability and low radiation dose. However if a panoramic radiograph already exists, a rough estimation of marginal bone level at premolar region is clinically acceptable bearing in mind that the bone height of the mandible premolar region might be overestimated as compared to bitewing radiograph.

Taurodontism
AbstractTaurodontism was hitherto considered to be a marker of oro-facial disorders. Since then, it has been reported with a moderately high-to-high prevalence on panoramic radiographs in case series of otherwise normal individuals a number of Middle Eastern and East Asian communities. This now understood higher than-formerly expected prevalence is important to the endodontist, orthodontist and restorative dentist. Therefore, the oral and maxillofacial radiologists should be aware of this phenomenon and its measurements to better advise their clinical colleagues. (Source: Oral Radiology)

Can narrowing of the mandibular canal on pre-operative panoramic radiography predict close anatomical contact of the mandibular canal with the mandibular third molar? A meta-analysis
ConclusionsAccording to the sign of narrowing of the mandibular canal, panoramic radiology used to assess the relationship between the mandibular third molar and the mandibular canal yielded high specificity, but low sensitivity. The absence of narrowing of the mandibular canal indicated that there was no close contact between these two structures. However, the presence of narrowing of the mandibular canal could not be used to accurately evaluate the relationship between these two structures, although it might indicate a high probability of close anatomical contact between these two structures. Further tests should be perf...

Benign osteoblastoma of the palate: a rare clinical presentation
AbstractOsteoblastoma is a rare, benign type of osteoblastic tumor. It constitutes approximately 1% of all primary bone tumors. Osteoblastoma most commonly affects the long bones; it very rarely affects the jaw bones. Because of its clinical and histological similarity with other bony tumors, such as osteoid osteoma and fibro-osseous lesions, osteoblastoma is a diagnostic challenge. Very few cases of osteoblastoma involving the maxillofacial region have been reported to date. We herein describe a 15-year-old female patient with osteoblastoma that presented as a palatal swelling of 6  months’ duration. (Source: Oral Radiology)
