Rhinocerebral mucormycosis is the most common variant and the presenting features in the head and neck region are seldom pathognomonic. The aim of this systematic review was to obtain a thorough insight into the predisposing factors, clinical features, disease course, management protocol, outcome, and prognosis.

: The aim of this study was to compare stock (Biomet-Lorenz) and custom (TMJ Concepts) total TMJ replacement prosthetics.

Inflammatory bowel diseases (IBD) are chronic inflammatory disorders of the digestive tract, and also involve systemic inflammatory diseases, known as extra-intestinal manifestations (EIMs). Timely and correct diagnosis of mucocutaneous EIMs could act as windows to detect and monitor IBD. We present a case of 52-year-old male patient of ulcerative colitis with two rare EMIs together at the same time, Pyostomatitis vegetans in oral cavity and Sweet's syndrome on skin. They presented as multiple small white or yellow pustules on the surface of the hyperemic fragile oral mucosa and abrupt appearance of painful, swollen, and erythematous papules on the skin, respectively.

To assess the mechanical characteristics and the clinical usefulness of beta-tricalcium phosphate (β-TCP) and hydroxyapatite (HA) bioblocks grafted in edentulous jaws of 12 patients.

Background: Emerging evidence has shown that sentinel node biopsy (SNB) is an oncologically safe option in early oral cancer patients when compared to elective neck dissection. However, its use on a routine basis could be associated with many challenges.Methodology: This online survey was conducted among the Indian Surgeons treating oral cancer patients to understand and comprehend the incidence and patterns of usage of SNB in their practice, their approach towards the use of SNB, and the possible challenges they face or perceive in its routine use in early oral cancer patients.

To create and assess a deep learning model using segmentation and transfer learning methods to visualize the proximity of the mandibular canal to an impacted third molar on panoramic radiographs.

: To investigate whether the copy number variation (CNV) of GSTM1 and GSTT1 is related to the occurrence of oral squamous cell carcinoma (OSCC) relapses, along the overall and progression-free survival of patients.

End-stage heart failure patients are functionally compromised by multiple physiological mechanisms, placing them at increased risk of peri- and post-operative complications. The study aims to evaluate if dental treatment performed prior to advanced cardiac interventions, including orthotopic heart transplant and mechanical circulatory support, increases the risk of adverse events.

Objective: Sagittal root position (SRP) and buccal-plate thickness are important considerations in implant treatment planning. The objective of this study is to classify the relationship of the SRP and angulation to the osseous housing for assisting treatment plan making for immediate implant placement (IIP) in the premolar region.Study Design: We classified the SRP and angulations of the maxillary and mandibular premolars and measured the buccal-plate thickness of 150 patients using cone-beam computed tomography (CBCT) to support clinical decision making.

Several cases of intraosseous mandibular tumors have been reported under the name “tubulopapillary hidradenoma-like tumor of the mandible (TPHLTM).” However, the intraosseous occurrence of sweat gland tumors needs to be reappraised. The aim of this review is to propose a new name for these tumors to reflect possible tumor origin. In view of the incidence and the tissue of origin, TPHLTM is more likely to be a salivary gland tumor than a sweat gland tumor. Among salivary gland tumors, a recently described salivary neoplasm called “sialadenoma papilliferum-like intraductal papillary tumor (SP-IPT)” seems to be histologically and genetically identical to tubulopapillary hidradenoma.

: The objectives of this study were to evaluate the value of tumor morphology, long-to-short diameter ratio (L/S), and ultrasound gray scale ratio (UGSR) in the differential diagnosis of parotid neoplasms.

The authors regret that this article contains errors in Figure 1, in which the histopathological photographs in Figure 1K and L were reversed. Moreover, in the legend of Figure 1, the experimental data described as “Hematoxylin and eosin staining (A, D, G, J)” and “immunostaining for ERα (D, H, I, P)” should have been described as “Hematoxylin and eosin staining (A, E, I, M)” and “immunostaining for ERα (D, H, L, P),” respectively.

Aging is associated with structural and functional cardiovascular changes that may affect microvascular free flap perfusion, which is a prerequisite for flap viability and flap success. This study aimed to investigate the impact of age on flap perfusion.

Growing up, I must have walked past posters at my grade school a thousand times. Those aquamarine tiled walls held posters with inspirational sayings. “Shoot for the moon, and if you miss, you will land among the stars”. Or, “You can have it all”. And while those posters were catchy and bright colored, appealing to a younger version of myself whose life was limited to plaid jumpers, textbooks and playing outside, they failed to warn me of the grit and strength that my life and professional choices would require.

A 38-year-old man was referred to our institute for the examination of asymptomatic swelling on the right posterolateral aspect of the hard palate. The patient noticed the swelling 2 months before when it increased to its present size and was perceived during tongue movement. The patient's medical, social, and dental history were nonsignificant. To the best of his knowledge, he was not allergic to any medication and did not undergo any prior surgery. He did not consume tobacco products or have a history of any parafunctional habit or trauma.

We aimed to validate and evaluate the comprehensive complication index (CCI) as a measure of postoperative complications (POCs) in head and neck squamous cell carcinoma (HNSCC) patients who had undergone free-flap reconstruction.

The goal of this study was to look into age, genetics, gender, oral mucosa diseases and systemic diseases as potential risk factors for the geographic tongue (GT) in a Chinese population.

In a recent lecture focused on evidence-based disparities in health equity, the speaker stated that “race is not biological.” This statement resonated with me for a variety of reasons, but mostly because this was the first time I had heard this stated. I subsequently learned through various readings, including in prestigious scientific journals such as Science, about increasing concerns that race has been historically used, perhaps inappropriately, to explain biological differences in a variety of health care settings, including treatment outcomes.

: The asymmetric mandible presents the clinician with unique anatomical challenges in orthognathic surgery correction. This study aims to investigate these characteristics of the asymmetric mandible: mandible bone thickness, soft tissue thickness, and the proximity of the bone cortex to the inferior alveolar nerve (IAN) canal.

To preliminarily evaluate the effect of individualized preformed titanium mesh in the treatment of orbital wall fractures with superior orbital fissure syndrome (SOFS).

The aim of this systematic review was to determine the computed tomographic (CT) imaging characteristics of maxillary and mandibular melanotic neuroectodermal tumor of infancy (MNTI). Two cases from our institution were also presented.

To compare the diagnostic efficacy of physical examination, ultrasound, and computed tomography for the detection of lymph node metastases (LNM).

: Mandibular osteomyelitis remains an incompletely understood entity, and treatment of its various presentations remains diverse. The purpose of this study was to review the necessity of antibiotic therapy after surgical treatment of mandibular osteomyelitis.

This systematic review aimed to summarize morphological changes in the temporomandibular joint (TMJ) in patients who underwent orthodontic treatment and were assessed by three-dimensional imaging techniques such as magnetic resonance imaging, cone beam computed tomography, and multidetector computed tomography.

It is one of the advantages listed in every introductory digital imaging lecture: easy transfer, and thus improved communication, of patient image data. But is it true? Sometimes it seems that it was easier to exchange images when film was used as the recording medium. A 2-film packet provided the ability to retain 1 image on site and mail the other to the appropriate party. Even more convenient and time saving was the compatibility of viewing the film with a light box. With film, there was no need to buy a separate optical scanner to connect to your computer so that you could retrieve image data from a CD because your computer did not come with a CD drive.

The aim of this study was to perform a systematic review of oral manifestations arising from oral piercings.

This study aimed to compare the clinical characteristics of patients with medication-related osteonecrosis of the jaw (MRONJ) and osteoporosis vs malignancy.

This study aims to determine the incidence of physiologic intracranial calcifications on cone beam computed tomography (CBCT) and to contribute to the differentiation between physiologic and pathologic intracranial calcifications by sharing their characteristic appearances, with the largest number of patients in the literature and many different types of physiologic calcifications.

. The International Classification of Disease defines burning mouth syndrome (BMS) as a chronic intraoral burning sensation, with no identifiable local or systemic cause. As current management is often unsatisfactory, the aim of this report is to describe a new treatment modality, i.e. low dose naltrexone (LDN).

INTRODUCTION

To characterize the oral alterations in patients with the congenital syndrome caused by Zika virus infection (CZS).

Oral verruciform hyperkeratotic lesions (OVHLs) affecting the gingiva and palate are frequent in proliferative verrucous leukoplakia (PVL). Intraoral hyperkeratotic lesions can also be observed in epidermolytic keratodermas, albeit such association has received limited attention in Oral and Maxillofacial Pathology. We report on five individuals whose plantar or palmoplantar keratodermas (PPKs) were confirmed after evaluation of gingival leukoplakic biopsies

Pleomorphic adenoma (PA) is the most common neoplasm of the salivary glands. Although several carcinomas have been reported to arise from PA, only one case of salivary gland secretory carcinoma (SC) ex pleomorphic adenoma has been previously reported. SC is a newly described salivary gland tumor harboring an ETV6-NTRK3 translocation, which is classically observed in secretory carcinoma of the breast, although other translocations have recently been observed. We report the first case of the molecular identification of a rare ETV6-RET translocation in an SC arising from a PA in the submandibular salivary gland (SC ex PA).

The aim of this study was to examine the clinical and histopathological effects of neoadjuvant intra-arterial chemoradiotherapy (IACRT) using cisplatin in combination with oral S-1 (tegafur/gimeracil/oteracil) on stage III and IV oral squamous cell carcinoma.

The ongoing pandemic of Coronavirus disease 2019 (COVID-19) required a firm and prompt effort into the development of an effective vaccine. Reports of adverse reactions are increasing. Lichen planus, and its oral variant, is a condition that has been previously reported associated with vaccines. This is one of the first report of oral lichenplanus(OLP) arising after any COVID-19 vaccine. Here we present two cases of OLP occurred after BNT162b2 mRNA COVID-19 vaccination (Comirnaty, Pfizer, New York, NY, USA; BioNTech, Mainz, Germany).

A 69-year-old woman presented to her dental surgeon with a painless swelling of the left face, and no other signs or symptoms. Initial radiologic findings revealed a multiloculated radiolucent area within the left mandible (Figure 1). Further clinical investigations included a computed tomography (CT) scan of the cranium, sinuses, facial bones and cervical spine (Figure 2). A partially corticated oblong radiolucency was noted in the left posterior mandible measuring approximately 40 × 20 × 12 mm.

To investigate morphological and surgical risk factors causing neurosensory disturbances (NSD) after bilateral sagittal split osteotomy (BSSO).

High-risk (HR) human papillomavirus (HPV) infection is recognized as a primary etiologic factor of anogenital cancers and more recently of a subgroup of oropharyngeal squamous cell carcinomas (OPSCC). The incidence of HPV-related OPSCC has increased dramatically in several developed countries in the past 3 decades and is currently the most common cancer caused by HR-HPV in the United States and Germany, surpassing cervical cancer. Consequently, the patient's demographic and clinicopathologic profile has shifted to nonsmoking and nondrinking younger men with higher schooling level and with a history of multiple oral sex partners.
