An investigation of tooth loss factors in elderly patients using panoramic radiographs
ConclusionsTeeth showing P2 or greater alveolar bone resorption, bridge, and apical lesions on panoramic radiographs are most likely to be lost in an elderly patient ’s near future. Consequently, this group should be encouraged to visit their dental clinics regularly and receive comprehensive instruction on individual self-care methods. (Source: Oral Radiology)

Low-dose cone-beam computed tomography in simulated condylar erosion detection: a diagnostic accuracy study
ConclusionsThe studied ULD-HD CBCT protocol can be recommended for the detection of mandibular condylar erosions due to the reduced radiation dose; however, ULD-NORM is not advocated for similar clinical use. (Source: Oral Radiology)

Taurodontism and C-shaped anatomy: is there an association?
ConclusionsA high correlation was revealed between taurodontism and complicated C-shape canal configurations. Practitioners should be very careful about the presence of C-shape morphology in taurodontism treatment, and various types of C-shaped morphology ranging from coronal to the apical direction.

Juvenile primary Sj ögren’s syndrome with ranula: is ranula a clinical sign that leads to early detection of Sjögren’s syndrome?
AbstractJuvenile primary Sj ögren’s syndrome (pSS) is rare. Although recurrent parotitis is reported to be the most common symptom of juvenile pSS, the clinical symptoms and features of the syndrome are not well understood and are poorly defined. Here we report a rare case of juvenile pSS in a patient with plunging ranula. The patient had no symptoms other than swelling of the oral floor and had no symptoms of parotitis. Magnetic resonance imaging (MRI) revealed the diagnosis of plunging ranula. In addition, the findings of the bilateral parotid glands on MRI and subsequent ultrasonography (US) strongly suggested SS. On...

A brief introduction to concepts and applications of artificial intelligence in dental imaging
This report aims to summarize the fundamental concepts of Artificial Intelligence (AI), and to provide a non-exhaustive overview of AI applications in dental imaging, comprising diagnostics, forensics, image processing and image reconstruction. AI has arguably become the hottest topic in radiology in recent years owing to the increased computational power available to researchers, the continuing collection of digital data, as well as the development of highly efficient algorithms for machine learning and deep learning. It is now feasible to develop highly robust AI applications that make use of the vast amount of data avai...

An unusual case of melanoma metastasis in the buccal space: learning by mistakes to distinguish it from salivary neoplasms
We report here the case of a woman with a melanoma metastasis in buccal fat pad, to evaluate the imaging features which might lead to the correct, although uncommon, diagnosis.Case presentationA 71-year-old woman presented with a painless visible swelling of the left cheek. MRI revealed the presence of a solid lesion located in the buccal fat pad with features suggestive of malignancy. It showed T1 hyperintensity and T2 hypointensity, and restriction of diffusion. Histological examination showed neoplastic cells compatible with melanoma.DiscussionThe lesion features (T1 hyperintensity and T2 hypointensity) initially lead o...

Multiple adenomatoid odontogenic tumours associated with eight impacted teeth
AbstractAdenomatoid odontogenic tumour (AOT) is a benign tumour that arises from odontogenic epithelial remnants. AOTs usually present as innocuous lesions with limited growth potential. Multiple AOTs are frequently reported in the literature, with reports of tumours associated with up to seven impacted teeth. Multiple AOTs have also been described in association with Schimmelpenning syndrome. This case report highlights the rare occurrence of multiple AOTs involving eight impacted teeth in a 9-year-old male patient. Radiographic examination showed features of enamel hypoplasia and multiple  prominent dilated gubernaculum...

A new classification proposal for sphenoid sinus pneumatization: a retrospective radio-anatomic study
ConclusionIn this study, sphenoid sinus pneumatizations were evaluated three-dimensionally with the help of CBCT, and a new classification suggestion was made to eliminate the classification confusion we encountered in our previous studies. Pneumatizations and variations can affect the field of operation and even change planning. It should be taken into account that the paranasal sinuses may have variations due to their surgical importance and their close association with many vital structures. (Source: Oral Radiology)

The practice of oral and maxillofacial radiology during COVID-19 outbreak
AbstractThe current coronavirus disease 2019 (COVID-19) outbreak has brought substantial challenges to the world health system, including the practice of dental and maxillofacial radiology (DMFR). DMFR will carry on an imperative role in healthcare during this crisis. This rapid communication has collected and evaluated all the best current evidence and published guidelines as well as professional recommendations to help maxillofacial radiologists and dental practitioners for safer radiological and imaging examinations on healthy, suspected, or confirmed COVID-19 patients during outbreak. Some strategies have been depicted...

Cone-beam computed tomography evaluation of impacted and transmigrated mandibular canines: a retrospective study
ConclusionTransmigration is common among impacted mandibular canines. Resorption of adjacent teeth roots was one of the possible complications of impaction and likely contact/proximity of incisive mandibular canal with impacted mandibular canines, which may pose difficulties in surgical treatment, can be better detected by CBCT.

Investigation of the effectiveness of CBCT and gray scale values in the differential diagnosis of apical cysts and granulomas
ConclusionThe presence of a well-defined cortical border or partial cortical border is a distinctive criterion for cysts. Additionally, the shape of the lesion was found to be a significant criterion for the separation of the two lesions. The shape of cystic lesions was circular and apical granulomas had a more curved shape. There was no relationship between the histopathological diagnosis of lesions and CBCT gray scale values.

Actinomycotic osteomyelitis with proliferative periostitis arising in the mandibular ramus: an unusual case with spontaneous bone regeneration after coronoidectomy
We report a rare case of actinomycotic osteomyelitis with proliferative periostitis arising in the mandibular ramus and spontaneous bone regeneration after coronoidectomy. A 14-year-old girl was referred for swelling in the right parotid-masseteric region and severe trismus. Contrast-enhanced CT revealed that heterogenous enhancement of the right masseter muscle, and a reactive bone formation over the lateral cortex of the right mandibular ramus and osteolysis of the condyle were seen in plain CT. MRI showed that the mandibular ramus was a low-signal intensity and the reactive bone on the ramus was signal intensity similar...
