abstract：OBJECTIVES:There is currently no standardized approach for assessing the depth of invasion (DOI) of oral tongue squamous cell carcinoma via diagnostic imaging. We investigated the usefulness of contrast-enhanced computed tomography (CECT) for estimating the pathological DOI of oral tongue squamous cell carcinoma by eva...
abstract：PURPOSE:The aim of this study was to investigate the effectiveness of cone-beam CT (CBCT) findings and gray scale values (GSV) in the differential diagnosis of apical cysts and granulomas. METHODS:Two independent researchers retrospectively analyzed the CBCT images of 21 teeth and histopathologically diagnosed them as...
abstract：: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 owin...
abstract：OBJECTIVES:This study aimed to assess the prevalence of incidental findings, not strictly related to dentistry, viewed with panoramic radiography. METHODS:Panoramic radiographs performed between December 2013 and June 2016 were retrospectively collected. These images were analyzed, searching for incidental findings. A...
abstract：OBJECTIVES:The aim of the present study is to identify the prevalence of radix entomolaris in mandibular first and second molars and to determine morphological classifications and associations with other root and canals. METHODS:Mandibular first and second molar teeth of 850 Turkish patients were evaluated using cone-...
abstract：:The 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 t...
abstract：OBJECTIVES:To compare characteristics of temporomandibular joint (TMJ) and related structures according to Angle class I, II1, II2, and III. METHODS:123 Chinese patients (13-36 years old, 60 males, and 63 females) were classified in four groups according to Angle's classification: skeletal class I (31 patients), skele...
abstract：:The Gubernaculum Dentis (GD) is an anatomical structure connecting the dental follicle of the permanent tooth to the overlying gingiva. It is composed of Gubernacular cord (GCo) and a surrounding bony canal called as Gubernacular canal (GC) or Gubernacular Tract (GT). GD is a physiologic structure that has claimed to ...
abstract：OBJECTIVES:The aim of this study was to compare the effective doses of orthodontic radiographs in children, adolescents, and adults. METHODS:We exposed a child, an adolescent (simulated by an adult female phantom), and adult male phantoms using common scanning protocols for panoramic radiography, cephalography, and co...
abstract：PURPOSE:Inferior alveolar nerve injury is a common complication following mandibular third molar extraction. Accurate pre-operative assessment of the anatomical relationship between the mandibular third molar and the mandibular canal could help to avoid this injury. We performed a eta-analysis to investigate whether pa...
abstract：:Synovitis, 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...
abstract：:Oculofaciocardiodental (OFCD) syndrome is a rare genetic disease, first reported by Hayward in 1980. This syndrome presents with various ocular, facial, cardiac, and dental symptoms, including congenital cataract, dysmorphic facial features, congenital heart disease, and enlarged roots, respectively. The most importan...
abstract：OBJECTIVES:L-3-[18F]-Fluoro-α-methyl tyrosine (FAMT), an amino acid positron emission tomography (PET) tracer, complements [18F]-fluorodeoxyglucose (FDG) in the diagnosis of malignancies. We compared the predictive ability of FAMT PET versus FDG PET regarding metastatic oral squamous cell carcinoma (OSCC) outcomes for ...
abstract：:Schwannoma is a benign nerve sheath tumor composed of Schwann cells. Schwannomas originating from ganglia are rare, and schwannomas of the submandibular ganglion or glandular branches have not been reported to date. We present a case of a Japanese woman in her sixties with a submandibular schwannoma originating from t...
abstract：:Synovial chondromatosis is a benign nodular cartilaginous proliferation that mainly occurs in large joints. The temporomandibular joint is considered to be rarely affected. Several cases of synovial chondromatosis of the temporomandibular joint have been reported with clinical and histological features. People with th...
abstract：:We herein report a case of squamous cell carcinoma of the buccal mucosa with N3 cervical lymph node metastasis in a 63-year-old man. The patient was treated with combination therapy comprising radiotherapy (2 Gy/day, total of 70 Gy), superselective intra-arterial chemotherapy via a superficial temporal artery (docetax...
abstract：OBJECTIVES:Secondary dentine is laid on pulp chamber walls with increasing age, and decreases pulp chamber size. This study aimed to investigate age estimation on cone-beam computed tomography (CBCT) images for forensic science, and the relationship between age and pulp chamber area of maxillary and mandibular molars. ...
abstract：OBJECTIVES:The purpose of this study was to clarify which panoramic radiographic features can predict the development of bisphosphonate-related osteonecrosis of the jaw (BRONJ).
