A girl in middle childhood was referred to the paediatric surgical team with acute colicky abdominal pain and bile-stained vomiting. This was preceded by a viral illness. Investigations revealed raised inflammatory markers, and imaging of the abdomen demonstrated ileal and jejunal thickening. Concerns were raised regarding whether she had inflammatory bowel disease. Endoscopy revealed gastritis and duodenitis, and colonoscopy was unremarkable. Video capsule endoscopy demonstrated ulcers in the jejunum and ileum...

INTRODUCTION AND IMPORTANCE: Odontogenic keratocyst (OKC) is a distinctive form of developmental odontogenic cyst that deserves special consideration because of its specific clinical behaviour and histopathologic features. The clinical and radiographic features of OKC are indefinite; while some may be associated with pain, swelling or drainage, most of them are asymptomatic. This case reports rare radiographic and histopathological features of recurrence OKC. CASE PRESENTATION: A 47-years-old male patient presented with a main complaint of a painful mass in the oral cavity with a history of previous lesions that occurred in the posterior portion of the mandible related to extraction of impacted third molar...

OBJECTIVE: To survey oral and maxillofacial surgeons (OMS) who perform temporomandibular joint replacement (TMJR) to determine whether length of surgery, specific TMJR protocols, or the incidence of complications are related to experience and case volume. STUDY DESIGN: An anonymous electronic survey was emailed to 407 surgeon members of the American Association of Oral and Maxillofacial Surgeons, American Society of Temporomandibular Joint Surgeons, and European Society of Temporomandibular Joint Surgeons known to have TMJR experience via publications or reputation...

STUDY DESIGN: A cross-sectional study was performed with a survey including CIPS, demographic, and training program structure questions distributed to all OMS training programs and residents in the United States. The primary predictor variable was gender, and the main outcome variable was the CIPS score...

OBJECTIVE: To analyze the effect of hookah and cigarettes on the oral mucosa of smokers through the use of exfoliative cytology. STUDY DESIGN: Smear samples were collected by exfoliative cytology from the tongue of 33 hookah smokers, 22 cigarette smokers, and 30 non-smokers. The selected analyses include micronuclei (MN), metanuclear anomalies, epithelial maturation, and cytomorphology (nuclear area [NA], cytoplasmic area [CA], and NA/CA ratio). RESULTS: The largest differences observed for MN and metanuclear anomalies were between cigarette smokers and the control group (notably 1 MN P = ...

OBJECTIVES: Computed tomography (CT) and cone beam computed tomography (CBCT) represent the main imaging modalities used in rhinosinusitis patients and are also important in odontogenic sinusitis (OS) diagnostics. Reports, however, often lack information on dentition. Here, we aimed to determine how maxillary dentition is initially interpreted in rhinosinusitis patients' CT/CBCT reports and which dental findings in particular are potentially missed, thus needing more attention. STUDY DESIGN: CT/CBCT scans and radiological reports from 300 rhinosinusitis patients were analysed focusing specifically on dental findings...

OBJECTIVE: Extranodal extension (ENE) is an important prognostic factor in oral squamous cell carcinoma (OSCC). This study aimed to evaluate the clinical significance of stratifying minor or major ENE in OSCC. STUDY DESIGN: This retrospective cohort study included 75 patients who had undergone neck dissection for OSCC and were classified as pN+. ENE was measured using hematoxylin-eosin-stained specimens and stratified into major (ENEma, >2 mm) and minor (ENEmi, ≤2 mm) by distance...

OBJECTIVE: To evaluate the state-of-the-art evidence for applying low-dose CBCT protocols in 3 stages of implant therapy (planning, insertion, and follow-up examination of peri-implantitis) and assess the overall body of evidence presented in the literature. STUDY DESIGN: The search was conducted in the MEDLINE/Pubmed and Scopus databases. Studies comparing low-dose CBCT protocols to a relevant reference standard in relation to any stage of implant therapy were included...

OBJECTIVES: To determine the prevalence of peri-implant diseases in patients treated in a university setting without a regular peri-implant supportive therapy schedule, and to identify the risk indicators associated with peri-implantitis. MATERIAL AND METHODS: A retrospective cohort study was made of patients with dental implants with at least 12 months of functional loading who did not receive regular peri-implant supportive therapy. Patient- and implant-related variables were retrieved, and clinical and radiological examinations were performed...

OBJECTIVE: This study aimed to assess the impact of oral medicine (OM) practitioners on the literature regarding oral potentially malignant disorders (OPMDs), focusing on oral leukoplakia. STUDY DESIGN: Using a bibliometric approach on the Scopus database until September 1, 2022, the top 100 cited articles were analyzed for article type, subtopic, specialty contributions, author metrics, and keywords. The Bibliometrix package for R and VOSviewer were used to evaluate interactions and generate science maps...

OBJECTIVES: Effective management of neck in oral squamous cell carcinoma (OSCC) is pivotal for oncological outcomes. Although consensus exists for ipsilateral neck dissection (ND), the necessity for contralateral ND remains controversial. This study aimed to assess the prevalence and implications of bilateral/solely contralateral (B/SC) lymph node metastases (LNMs) to determine the need for contralateral elective ND. Additionally, it examined the prevalence and implications of occult B/SC metastases...

Ameloblastoma in dogs most often has a highly conserved acanthomatous cell morphology and is recognized as canine acanthomatous ameloblastoma (CAA) while conventional ameloblastoma (CA) makes up a smaller yet morphologically diverse group of epithelial odontogenic tumors. In humans, a rare desmoplastic histological subtype has distinctive clinical, radiological, and microscopic features. Desmoplastic ameloblastoma (DA) has not previously been described in dogs, although it has been rarely referenced in the veterinary literature...

Rhabdomyosarcoma with TFCP2-related fusions (TFCP2-RMS) is a rare entity that commonly affects young adults with a predilection for skeletal involvement. We herein report a 40-year-old female patient with TFCP2-RMS who was misdiagnosed as fibrous dysplasia or low-grade central osteosarcoma of the mandible by referring institutions. Histologically, the tumor showed dominant spindle cells and focal epithelioid cells with marked immature woven bone formation. Immunophenotypically, in addition to the characteristic expression of myogenic markers, ALK, and cytokeratins, tumor cells also unusually expressed osteogenic markers, such as MDM2 and SATB2...

The search strategy was set as a combination of the following keywords: "Artificial Intelligence," "Machine Learning," "Deep Learning," "Neural Networks," "Head and Neck Imaging," and "Maxillofacial Imaging...

OBJECTIVE: Oral submucous fibrosis (OSF) is a chronic, insidious, progressive mucosal disease that may be affected by mutations in the Wnt/β-catenin signaling pathway. Panax notoginseng saponins (PNS) is a powerful anti-fibrosis agent; however, its effect and mechanism in treating OSF remain unclear. This study investigated the effect and mechanism of PNS treatment for OSF. STUDY DESIGN: Arecoline was used to induce OSF models in vivo and in vitro, which were then treated with PNS...

OBJECTIVE: The aim of this study was to present the development of a database (dataset) of panoramic radiographs. STUDY DESIGN: Three radiologists labeled an image set consisting of 936 panoramic radiographs. Labeling includes tooth numbering (including teeth present and missing) and annotation of dental conditions (e.g., caries, dental restoration, residual root, endodontic treatment, implant, fixed prosthesis, incisal wear). The annotation process was performed in a Picture Archive and Communication System software customized for the study purposes using a small bounding box to delimit the entire tooth and items for radiographic diagnosis and a large bounding box to simultaneously delimit the 2 dental arches (maxilla and mandible)...
