Objectives: To present our experience with a novel, same day access (SDA) scheduling model for outpatient clinical care in Oral and Maxillofacial Surgery (OMS).Study Design: The primary outcome variable was OMS patient scheduling in a hospital-based outpatient clinic. Patients were given a specific appointment time to be seen the same day they contacted the clinic. This SDA clinic was compared to previous patient scheduling models for patient satisfaction, appointment wait times, annual clinic volume, no show rates, and access to care.

Medication-related osteonecrosis of the jaw (MRONJ) is an uncommon but highly morbid adverse event of certain medical therapies. Although classically induced by bisphosphonates, the recent advent of monoclonal antibodies is contributing to a rise in cases. In this case report we present a rare case of Golimumab associated MRONJ and discuss the possible mechanisms of pathogenesis.

ChatGPT has been available to the public since December 2022.1 As of this writing, its 4th iteration (Generative Pre-trained Transformer [GPT-4])2 was made available in March 2023 and this artificial intelligence (AI) has already “evolved”. As just one example, the current version has the ability to devise rational and mostly reasonable differential diagnoses and also suggest likely diagnoses based on a constellation of signs and symptoms with and without inclusion of laboratory findings (Figures 1-3); this is much more sophisticated than what the original version was capable of doing with similar search terms.

During endodontic treatment or retreatment, cone beam computed tomography (CBCT) scanning is often necessary for evaluating inflammatory resorptive defects and making surgical treatment plans [1, 2]. However, CBCT has limitations, including the production of artifacts that reduce the contrast between adjacent objects, significantly affect the quality of CBCT images, and eventually lead to inaccurate or false diagnoses.

Cone beam computed tomography (CBCT) is widely used before implant planning to evaluate alveolar bone density and to assess the presence and status of bone graft material. CBCT provides precise information regarding bone density, shape, and contour.1 However, it does not have the ability to identify graft materials, depict remodeling changes, or determine the integration status of graft material at the implant site. This is because graft materials and bone can often exhibit similar densities despite having different compositions.

To evaluate the effects of spatial resolution and application of enhancement filters in the diagnosis of simulated furcation defects and image quality with intraoral radiographs.

Head and neck lymphomas, either of nodal or extranodular anatomic sites, are quite common. However, a small percentage of lymphomas occur in salivary glands, including those found in the parotid glad [1, 2]. Salivary gland lymphomas may be detected in patients with a history of Sjogren's syndrome and myoepithelial sialadenitis (MESA) [3]. Benign lymphoepithelial lesion (BLL) may also herald lymphoma [4, 5].

Oral medicine is the specialty of dentistry responsible for the oral health care of medically complex patients and the diagnosis and management of medically related diseases, disorders, and conditions affecting the oral and maxillofacial region. 1 As such, specialists undertake broad training to prepare them for the intricacies of clinical practice in the field. Oral medicine practitioners treat oral manifestations of systemic disorders, head and neck effects of oncologic therapy, orofacial pain, oral mucosal diseases, and salivary gland disorders in patients with rheumatologic or autoimmune disease, to mention a few challenging scenarios.

Squamous cell carcinoma (SCC) of the tongue frequently metastasizes to the cervical lymph nodes1, 2. Metastatic cervical lymph nodes (MCLNs) involved in SCC of the tongue have been implicated as important factors in treatment planning and patient prognosis3,4,5,6,7. Magnetic resonance imaging (MRI)2,11, computed tomography (CT)8,9,10, positron emission tomography (PET)-CT12,13, and ultrasonography (US)14,15 have been employed to detect MCLNs, but this task is sometimes challenging when based only on visual image interpretation.

The purpose of the systematic review was to purview the role of endoscope, to determine the range of information, summarizing the evidence for the benefit of surgeons on endoscopic-assisted intraoral approach.

Regeneration methods are needed to repair the large maxillary and mandibular bone defects; however, the regeneration of these defects is a challenge in clinical medicine owing to the variety of the involved tissues and the size of the defects1. To regenerate these defects, tissue engineering seems to be a promising approach. Tissue engineering is a multidisciplinary method that uses the principles of biology and engineering2. Initially, tissue engineering was mainly focused on developing biologically functional alternatives, which could show the properties of natural tissues or organs by restoring, preserving, or improving their function.

Central vascular malformations (CVMs) of the mandible are rare and can have varied clinical and radiological characteristics, thus making differential diagnosis difficult. We retrospectively reviewed 5 patients with proven CVM who underwent computed tomography (CT) and magnetic resonance imaging (MRI), including diffusion-weighted imaging (DWI) (and magnetic resonance angiography (MRA) for one patient), to assess the characteristic imaging findings of this lesion. CT revealed multilocularity in 3 lesions.

Fibrohistiocytic and fibroxanthomatous lesions of bone encompass a broad spectrum of morphologic and radiographic presentations. Understandably, a plethora of descriptors and diagnoses have been used to classify these lesions. The rare gnathic forms are likewise subject to numerous taxonomic groupings and provide an additional challenge for definitive characterization. The World Health Organization (WHO) traditionally classified fibrohistiocytic tumors of bone as one of three entities with different presentations: Fibrous cortical defect (FCD), non-ossifying fibroma (NOF) or benign fibrous histiocytoma (BFH).

Clinic and radiologic examination are important for correct diagnosis and treatment planning in dentistry. Dentists often need to treat large numbers of patients every day. A large number of dental radiographs are taken daily as an important ancillary diagnostic tool.1. The radiological interpretation is primarily done by dentists. This process takes the time of the physicians in the clinic and can cause misdiagnosis or underdiagnosis due to the personal factors of physicians such as fatigue, emotions, and low experience levels.

The purpose of this study was to evaluate mandibular advancement for cases of mandibular deficiency with changes in vocal cord grade and intubation difficulty at subsequent surgery requiring intubation.

Epithelioid inflammatory myofibroblastic sarcoma (EIMS) is a rare variant of inflammatory myofibroblastic tumors located mostly in the intra-abdominal region. Herein, we present a case of a 32-year-old male with a lobulated growth in the right maxilla. Radiology revealed a solitary osteolytic lesion with an irregular margin, causing buccal and palatal cortex erosion. Histopathology revealed a tumor composed of spindle-shaped fascicles that blend into sheets of round to ovoid-shaped epithelioid cells, areas of myxoid changes, and necrosis.
