Fungal infections in dentistry: clinical presentations, diagnosis, and treatment alternatives
Oral candidiasis is a common opportunistic infection that requires knowledge of the various clinical presentations and management strategies for successful treatment.Numerous local and systemic factors contribute to the development of candidiasis, and the infections can range from superficial mucocutaneous overgrowths to invasive bloodstream infections with a high mortality rate. In addition to Candida albicans, various fungal strains have been isolated from the oral cavity, including C. tropicalis, C.

Oral lesions in patients with SARS-CoV-2 infection: could the oral cavity be a target organ?
Several viruses transmitted through saliva, such as herpes simplex virus, cytomegalovirus, and Zika virus, are capable of infecting and replicating in the oral mucosa, leading to painful oral ulcers. Few studies have described the oral manifestations of coronavirus disease 2019 (COVID-19). There is growing evidence that angiotensin-converting enzyme 2 (ACE2), the main host cell receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is highly expressed on the epithelial cells of the tongue and of the salivary glands, which may explain the development of dysgeusia in patients with COVID-19.

Intraneural perineurioma of the mandible: case series of a rare entity
Perineuriomas are benign peripheral nerve sheath tumors composed of perineurial cells. Functionally, the perineurium is the outer sheath around peripheral nerve fascicles, and it modulates external stretching forces, regulates endoneurial pressure, and acts as the blood –nerve barrier.1 Unlike Schwann cells and fibroblasts, perineurial cells synthesize basement membrane proteins, such as laminin and type IV collagen, and express epithelial membrane antigen.2 (Source: Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics)

Hyaline fibromatosis syndrome: a case report
Hyaline fibromatosis syndrome (HFS) is a rare monogenic disease inherited in an autosomal recessive pattern and characterized by hyaline deposits on the skin, mucosa, and multiple organs; osteoporosis; and joint contractures. This progressive condition is caused by mutations in the gene encoding the anthrax toxin receptor 2 protein (ANTXR2). HFS is a disabling disease, and patients suffer from progressive pain and disfiguring symptoms. There are few published case reports detailing oral findings in patients with this condition.

An increase in the number of teeth is termed supernumerary teeth.1,2 These teeth can be present both unilaterally or bilaterally, in one jaw, or in both jaws.2 In the maxilla, the anterior region is the most common location, and a solitary tooth in the midline is referred to as mesiodens. However, supernumerary teeth are more often seen in the mandible, especially in the premolar region, and are referred to as peridens.1,2 Supernumerary teeth distal to the molars are referred to as distodens.2 This type of dental anomaly is commonly associated with developmental disorders, such as Gardner syndrome and cleidocranial dysplas...

Journey of the notochord: linking embryology to radiologic interpretation of the craniocervical junction
The notochord is a mesoderm-derived cylindrical midline structure and a defining feature found in all chordates. In vertebrates, the notochordal process represents the initial embryologic axial skeleton and plays important structural and signaling roles in the development of the vertebral column, nervous system, and skull base. Besides persisting postnatally as the nucleus pulposus of the intervertebral disks, the remaining notochord typically regresses during fetal development after completion of its principal tasks.

Quantification of tmj rheumatoid arthritis on positron emission tomography scans using rover software
Inflammation of the temporomandibular joint (TMJ) has a relatively high correlation (> 17%) to the late stages of rheumatoid arthritis (RA). RA is a chronic inflammatory autoimmune disease that causes cartilage and bone destruction. Cell activity of TMJ was measured by using 2 radiotracers, [18 F]-fluoro-2-deoxy-D-glucose (FDG) and [18 F]-sodium fluoride (NaF), for staging and surveillance of RA.

Clinical and radiographic manifestations with 3-dimensional printed model of true bony ankylosis of the temporomandibular joint: a case report
We present a case of a 20-year-old male who presented with facial asymmetry, severe trismus since early childhood, generalized physical weakness, and other skeletal deformities, including pigeon chest and kyphoscoliosis. No clear history of trauma was elicited. However, early childhood trauma was considered a possibility. (Source: Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics)

Stationary intraoral digital tomosynthesis using carbon nanotubes field emission x-ray technology: clinical prototype
Tuned aperture computed tomography (TACT) and intraoral tomosynthesis were studied in the past and demonstrated improved detection of various dental diseases. However, interest in TACT waned because the technology was not viable for clinical use. Recently, interest resurged with the advent of the carbon nanotube field emission x-ray source array technology. Researchers from the University of North Carolina (UNC) Department of Physics and Astronomy and the UNC School of Dentistry designed, patented, and conducted several benchtop studies to demonstrate its utility.

Microcomputed tomography of calcium-hydroxide exposed vital nerve tissue: a pilot protocol
Calcium hydroxide (CH) preparations are used in many endodontic procedures. Extrusion of CH into the mandibular canal may cause inferior alveolar nerve (IAN) injury. With an in vivo rat sciatic nerve sample, this phenomenon was subsequently imaged by using multiple modalities. (Source: Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontics)
