To assess trabecular bone structure as calculated with fractal analysis by two binarization processes: White and Rudolph's original method (WR.o) and a revised version (WR.r). Fractal dimension (FD) values calculated with WR.r (FD.r) and a grayscale-based method (FD.f) were also compared. FD, histogram parameters, and lacunarity were compared by dentate status, jaw location, and sex.

The emergence of monkeypox (MPX) in humans is a global concern during the current COVID-19 crisis. Human MPX is a viral disease of animal origin (zoonosis) caused by a virus of the orthopox family and is closely associated with smallpox viruses. Although the first case was reported in the mid-1900s in Africa, it is now spreading to different parts of the world, which has led the World Health Organization (WHO) to declare it as a "global emergency." Monkeypox virus (MPXV) infections have been reported not only in African countries, but also in high-income settings such as the USA, Canada, Australia, Singapore, and several European countries, including the UK, Sweden, Spain, Portugal, Netherlands, Italy, Germany, Belgium, and France.

Synovial chondromatosis (SC) of the Temporomandibular Joint (TMJ) is a synovial membrane disease characterized by the formation of cartilaginous nodules (CN), that may erode the skull base. Historically, cases with skull base involvement have been treated with open surgery. We report a case of TMJ SC with skull base perforation treated and repaired via minimally invasive TMJ Arthroscopy and describe the advanced endoscopic operative maneuvers performed.

Repositioning of the maxilla, mandible, and chin to restore facial harmony can be safely and effectively accomplished with concomitant procedures to manage obstructive nasal breathing, such as nasal septoplasty and bilateral inferior turbinate reductions, as well as cosmetic procedures, such as neck rejuvenation, rhinoplasty, otoplasty, blepharoplasty, and submental liposuction.1-5 Orthognathic correction has been shown to significantly improve the quality of life in individuals with congenital or acquired dentofacial deformities.

The aim of this study was to evaluate and compare quality of life (QoL) parameters in patients with oral potential malignant disorders (OPMD), namely oral lichen planus (OLP) and oral epithelial dysplasia (OED).

A 50-year-old Brazilian man presented to the emergency department with two painful ulcers of the right buccal mucosa. He first noticed these lesions 3 months earlier, after the extraction of adjacent maxillary teeth. Later, the patient returned to the outside provider for follow up due to increased pain and lesion size. The patient was referred to an outside oral and maxillofacial surgeon for further evaluation, who then initiated referral to our academic center. In addition to the oral mucosal lesions noted, the patient reported unintentional weight loss of 15 pounds.

: To evaluate the influence of extensive use of a photostimulable phosphor (PSP) receptor on the diagnosis of proximal carious lesions.

The core outcome set (COS) refers to the minimum set of outcomes that should be reported by all clinical trials in a particular health field. The use of COS in clinical studies can reduce the heterogeneity caused by the use of different outcomes across different clinical studies, facilitate the systematic review of different clinical studies on the same topic, reduce selective reporting bias, and increase the utility of clinical studies. The importance of COS in oral health has recently been recognized.

The objective was to evaluate stiffness as a prognostic factor for tongue squamous cell carcinoma (TSCC).

Objective: To compare volume and surface area measurements of the lateral and medial pterygoid and masseter muscles (LPM, MPM, and MM) as calculated on magnetic resonance imaging (MRI) based on the position of the temporomandibular joint disk, mouth position, and patient sex, and to calculate the correlations of the measurements among the muscles.Study Design: Measurements of muscle volume and area were performed on MRIs of 51 patients. Wilcoxon, Kruskal-Wallis, and Mann-Whitney U tests were used to calculate the significance of differences in measurements.

Sporadic central giant cell granulomas of the jaws (GCGJ) are often solitary lesions, characterized by KRAS, FGFR1, and TRPV4 somatic mutations. Multifocal lesions may occur and are associated with hyperparathyroidism or underlying syndromes, such as cherubism, marked by SH3BP2 mutations, and RASopathies, which are caused by mutations in the FGFR-RAS-RAF-MEK-ERK signaling cascade. The diagnosis of multiple GCGJ can be challenging. The present case reports a fourteen-year-old boy with multiple central GCGJ and no obvious syndromic trait.

The aim of this study was to measure the volume and visually assess 3-dimensional (3D) virtual models of pulp cavities obtained through semiautomatic segmentation on images from 6 cone beam computed tomography (CBCT) units compared with the reference standard of micro-CT.

A 58-year-old white female was referred to the oral and maxillofacial surgeon for evaluation of a soft tissue lesion on the left lower lip with a clinical impression of mucocele. At the time of the appointment, the lesion had significantly decreased in size. The clinical diagnosis of a resolving mucocele was established, and the patient decided to monitor the lesion. Extraoral and intraoral examination failed to reveal any significant asymmetry or mass effect besides the referred area on the lower lip.

Infectious status may be life threatening in hematopoietic stem cell transplant (HSCT) recipients. The aim of this study was to evaluate the effect of oral status on infectious conditions during the neutropenic phase after HSCT.

Anterior disk displacement (ADD) is a common type of temporomandibular joint (TMJ) internal derangement. In adolescents, the relationship between ADD and dentofacial deformities are brought into focus. Whether treatment is needed, or what kind of treatment are effective are still without a consensus. From the literature review, the consequences of ADD without treatment and the effect on disk repositioning were summarized. The results showed that after ADD, condylar height was prone to reduce that may lead to or aggravate dentofacial deformities in adolescents.

A 16-year-old female presented for routine dental care. On initial examination, a single, well-defined, sessile, firm exophytic submucosal lesion was detected on the right posterolateral border of the tongue. The lesion presented as a smooth pink dome-shaped nonulcerated mass. It was non-tender to palpation. According to the patient, it had been present for several years (Figures 1 and 2). At the time of presentation, the patient did not have fever, fatigue, airway obstruction, or lymphadenopathy.

Objective: This study aimed to compare the immunoexpression profile of tumor stem cell (TSC) biomarkers CD44, ALDH1, OCT4, and SOX2 in salivary gland tumors (SGTs).Study design: Sixty tissue specimens of salivary gland tumors (SGTs), including 20 pleomorphic adenomas (PAs), 20 adenoid cystic carcinomas (ACCs), and 20 mucoepidermoid carcinomas (MECs), in addition to 4 samples of normal glandular tissue, were subjected to immunohistochemistry. The expression of the biomarkers in the parenchyma and stroma was evaluated.

Oculodentodigital dysplasia (ODDD; MIM #164200), a rare genetic disorder characterized by abnormal craniofacial, dental, ocular, and digital features, is caused by mutations in GJA1 (gap junction alpha-1) gene and inherited in an autosomal dominant pattern. However, an autosomal recessive pattern is also reported. Here we described 2 families with members affected by ODDD. In the first family, the c.752G>C (p.S251T) and c.848C>T (p.P283L) heterozygous missense mutations and the c.825C>T (p.T275T) silent mutation were identified in the proband, which showed mild ODDD phenotypes, and in his mother, which displayed hemolytic anemia and thrombocytopenia.

Condylar resorption (CR) is a temporomandibular joint (TMJ) disease that causes various physical or functional defects. We aimed to find the association between CR and bone metabolism levels.

Orthognathic surgery (OS) alters the patient's facial profile, and it warrants discussion whether these alterations in facial structures can occasionally contribute negatively to the patient's mental health. Little is known about whether this burden can exacerbate previous psychiatric conditions or lead to new psychiatric morbidity. The lengthy treatment process (1), risks entailed by the surgery, peri- and postoperative complications, and adjustment to changes in physical appearance can strain the patient mentally during treatment.

This study compared clinical and magnetic resonance imaging (MRI) findings in patients with anterior disk displacement without reduction (ADDWOR) who improved to anterior disk displacement with reduction (ADDWR) vs. patients who did not improve after mandibular manipulation (MM) and conservative self-administered physical therapy (CSAPT).

Although the COVID-19 pandemic eventually will come to an end, SARS-CoV-2 is likely to remain with us as an endemic cause of disease.1 Those entering the hospital environment, nursing homes, and other facilities that provide human care still are mandated to wear masks to reduce the risk of spread and to promote safety.2 There is another disease that recently erupted around the globe called monkeypox, which poses a new risk for health care professionals. We as practitioners are continually in contact with patients who may be infected with these and other diseases.

Synovial chondromatosis (SC) is a rare disease characterized by the formation of cartilaginous bodies arising from the proliferation of mesenchymal remnants present in the synovial membrane1. It was first reported by Auxhausen, in 1933. It mainly affects the large joints of the human body, such as the hip, knee, ankle, elbow, wrist, and shoulder, but has rarely been reported in the temporomandibular joint 2,12.

This study investigated differences in trabecular structure and mandibular cortical thickness in adults related to vertical facial type (VFT), sex, and their interactions.

Retro-odontoid pseudotumor (ROP) is a benign proliferation of soft tissues posterior to the odontoid process. It can be associated with both inflammatory and noninflammatory arthritis. Altered biomechanics and atlantoaxial instability are the major contributing factors. There are no characteristic clinical findings. In the majority of cases, ROP is detected as an incidental finding in imaging. Early diagnosis of the lesion is important because of its proximity to the spinal canal and spinal cord.

The aim is to retrospectively analyze outcomes from surgical and non-surgical treatments for head and neck lymphatic malformations (LMs) in children.

The recent trend favors the open reduction and internal fixation of condylar fractures to prevent long-term consequences. Nonendoscopic intraoral approach is an option for management without a visible scar. The purpose of this systematic review was to explore the evidence, armamentarium, methods of reduction and fixation, challenges, and complications.

The COVID-19 pandemic continues to evolve and spread with new variants of SARS-CoV-2 across the globe, as well as bring to clinical attention several post-COVID conditions. We report a post-COVID condition observed at our tertiary care center: spontaneous de novo development of steroid induced avascular necrosis in patients who have recently recovered from COVID-19 following high dose steroid usage in a short span of time. Pre-COVID published literature indicates that these lesions were seen very rarely in the jaws and were related to long-term usage of steroids and recent tooth extraction.
