Glomus tumors are rare benign neoplasms usually occurring in the upper and lower extremities. However, oral cavity involvement is rare, with only a few case reports. We present a 37-year-old male patient with a chief complaint of an exophytic lesion in the left buccal mucosa for one year referred to our center. At the time, he did not have any pain or lymphadenopathy. The patient underwent surgery using a high-power CO2 laser. His histopathological examination revealed a glomus tumor. After 2 years of follow-up, no evidence of recurrence was detected...

Myofibromas are fibrous tumours that could be of familial or non-familial origin, belonging to the fibroblastic and myofibroblastic subset with a wide spectrum of clinical behaviour. Oral myofibromas present with a broad range of differential diagnoses, including benign and malignant lesions. Histopathologically, these lesions may imitate many other soft tissue tumours of the oral cavity, such as spindle cell tumours of nerve, smooth muscle cell origin, and other myofibroblastic lesions, thus leading to misdiagnosis and mistreatment...

Calcifying odontogenic cyst (COC) or Gorlin's cyst categorized as a distinct entity by Gorlin et al . in 1962. It is a rare benign developmental cystic lesion that accounts for less than 1% of all odontogenic cysts. It can occur in association with various types of odontogenic tumors such as odontomas. COC is a hybrid lesion of the jaw presenting a manifold variety of clinical behaviors and histopathological characteristics including cystic, solid (neoplastic), and aggressive forms. COC exhibits diversity in terms of its clinical presentations, histopathologic features, and biological behavior...

Syringomas are benign tumours originating from the eccrine ducts. Lower eyelid is the commonest site of origin. Very few cases have been reported in literature till date. Histopathology demonstrates normal compressed eccrine ducts in the fibrous capsule along with tumour cells arranged in tubules and solid islands. This report describes a case of syringoma on the lower eyelid in a female patient.

UNLABELLED: Sex determination in forensic medicine is considered one of the first and foremost steps in personal identification. The need for identifying the exact sex of the individual arises when deciding whether a person can exercise certain civil rights reserved for one particular sex, for competing in sex-specific athletic and sports events, legitimacy, divorce, paternity disputes and also to some criminal offenses. Nuclear sexing by Barr body examination can be done using buccal smears to establish the sex of the individual when routine methods fail to disclose the exact gender of the individual...

A superficial mucocele is a unique variant of a mucocele of the oral cavity that was described by Eveson for the first time in 1988. It occurs due to subepithelial extravasation of sialomucin at the epithelial-connective tissue interface and is related to damage of the minor salivary gland ducts. Clinically, they appear as small, asymptomatic, clear, tense vesicles with a predilection for the soft palate, retromolar pads, and posterior buccal mucosa. They are reported to occur more frequently in women than in men...

CONTEXT: The study of palatal rugae forms an important basis of human identification, especially due to mass disasters where routinely used techniques may not be helpful. AIMS: This study aimed at evaluating the palatal rugae and incisive papilla on the basis of shape. SETTINGS AND DESIGN: The study was conducted in 280 individuals (males and females) among dental students of Dayananda Sagar College of Dental Sciences. MATERIALS AND METHODS: The study included 280 students from Dayananda Sagar College and out-patients from the orthodontics department...

BACKGROUND: Cell adhesion molecules (CAMs) are found on the surface of all cells, where they allow dynamic processes to take place. These include cadherins, integrins, selectins and Immunoglobulin superfamily. Directly associated with β-integrin tails is a multidomain protein known as paxillin. However, CAMs participate in cell-cell and extracellular matrix-cell interactions during histomorphogenesis in the various phases of odontogenesis. Some tumours or cysts like ameloblastoma (AB) or odontogenic keratocyst (OKC) having odontogenic origin show disturbance in the interaction of these CAMs...

BACKGROUND: The oral health of individuals is undoubtedly affected by the fact that fungal microorganisms are currently resistant to the conventional antifungal drugs used. Still, there are numerous emerging therapeutic alternatives available like phytotherapy. The phytochemistry of various plant species has indicated that phytochemicals could be a better source of medicine with outstanding antifungal, healing, anti-inflammatory spectrum, and antioxidant properties. AIM: To evaluate the antifungal efficacy of silver nanoparticles of vanilla pods against Candida albicans , Candida glabrata , and Candida krusei and to compare with Fluconazole...

INTRODUCTION: Oral cancer is the sixth-most common cancer globally. The survival rate of oral cancer is 5 years, depending on the stage it is diagnosed. To diagnose in the early stage, specialised tumour markers may assist and also help in improving the survival rate of oral cancer. ErbB2 is a transmembrane cell surface receptor required in signal transduction and an essential part of signalling pathways that take part in controlling the basic cellular processes like cell cycle, migration, metabolism and survival, besides cellular proliferation and differentiation...

BACKGROUND AND AIM: USP22 is a positive regulator in tumor growth, its depletion leads to cell cycle arrest at G1 phase. USP22 over expression was positively correlated with proteins involved in proliferation and negatively correlated with tumor suppressor protein tumor supprn. Ki-67 expression is associated with USP22 over expression in oral squamous cell carcinoma (OSCC) and also in cervical and prostate cancers. The aim of this study is to evaluate the expression of USP22 and Ki-67 in OSCC by using an immunohistochemical staining procedure...

BACKGROUND: Early diagnosis is the single most effective means of reducing the mortality rate of oral cancer. AIM: This study was undertaken to assess the expression of minichromosome maintenance protein 5 (MCM5) in oral epithelial dysplasias and oral squamous cell carcinomas (OSCCs) and to evaluate their possible role as a biomarker for early diagnosis and prognosis of OSCC. DESIGN: A retrospective cross-sectional study. MATERIALS AND METHODS: The study was conducted to assess the expression of MCM5 immunohistochemically in the tissue samples of oral epithelial dysplasias ( n = 27) and OSCCs ( n = 30) diagnosed between 2014 and 2019...

BACKGROUND: Cancer of the lip and the oral cavity is collectively the sixth most common malignancy worldwide, out of which 90% are oral squamous cell carcinomas (OSCCs). Oral cancer survival rates depend mainly upon the stage in which it is diagnosed. Successful early detection would eventually increase the survival rate. OSCCs may be preceded by potentially malignant disorders (PMDs) that are characterised by visible clinical changes in the oral mucosa. Correct diagnosis and timely treatment of PMDs may help prevent malignant transformation in oral lesions...

BACKGROUND: Inflammatory cells and cytokines in the chronically injured mucosa promote fibrosis in the oral submucous fibrosis (OSF) fibrotic milieu. Osteopontin (OPN) is a wound-healing mediator that upregulates the inflammatory response and is involved in the malignancy and fibrosis of multiple organ systems. OBJECTIVES: We investigated the expression of OPN in oral potentially malignant disorders (OPMDs) and oral squamous cell carcinomas (OSCCs) to determine its role in the malignant transformation and fibrosis of oral tissues...

INTRODUCTION: Langerhans cells (LCs) are dendritic cells (DCs) of the epithelium which play a role in an array of oral lesions from gingivitis to oral cancer. Oral submucous fibrosis (OSMF), a potentially malignant disorder (PMD), is an insidious chronic disease with juxta-epithelial inflammatory changes leading to fibrosis. LCs may play a part in the ongoing inflammatory dysregulation of OSMF. OBJECTIVE: The study was aimed at elucidating the distribution of LCs in varying grades of OSMF...

BACKGROUND: The focus of caries research has switched to early identification and non-invasive treatment of carious lesions. AIM: This study aimed to evaluate and compare the remineralising potential of Ocimum (O.) basilicum varnish and fluoride varnish on initial enamel caries. METHOD: The authenticated O. basilicum seeds were procured from a repository, and the extract was prepared using the Soxhlet method, which was vortexed with Indian Pharmaceutical (IP)-graded chemicals to obtain varnish...

AIM: Oral cancer is one of the top three types of cancer and is of significant public health importance in India. A common post-translational modification in cells is ubiquitination/deubiquitination, and its dysregulation is closely associated with the development of cancer. Studies on the role of ubiquitination in oral squamous cell carcinoma (OSCC) are lacking. Increased expression of usp36 has been observed in various types of cancer, and this study aimed to check the gene expression of usp36 in OSCC patients...

BACKGROUND: Type II diabetes mellitus (T2DM) is a metabolic disorder. It is thought to be an autoinflammatory disease, as inflammatory mediators are associated with the progression of the disease. Visfatin, an adipokine, is linked to insulin resistance. AIMS: We aimed to study serum and salivary visfatin levels, at the time of diagnosis of T2DM, in middle-aged individuals, in the context of other diagnostic parameters like fasting blood sugar (FBS), postprandial blood sugar (PPBS), and glycated haemoglobin A1c (HbA1c)...

Rickets is a disorder caused by a lack of vitamin D, calcium or phosphate. It leads to softening and weakening of the bones. Dental manifestation of rickets includes enamel hypoplasia and delayed tooth eruption. The most important oral findings are characterised by spontaneous gingival and dental abscesses occurring without a history of trauma or caries. Radiographic examination revealed large pulp chambers, short roots, poorly defined lamina dura and hypoplastic alveolar ridge. These dental abscesses are common, and therefore, extraction and pulpectomy are the treatment of choice...
