Recent advances in DNA sequencing technology have facilitated rapid advances in the analysis of the human microbiome and its role in human disease. Several studies have now shown that OSCC and some oral premalignant conditions are associated with alterations in the oral microbiome. These studies raise questions regarding the role of the oral microbiome in the progression of oral malignancies and whether microbiome change is a significant risk factor in the development of oral cancer.

Background: Metabolomics is the study of metabolome which describes the full repertoire of small molecules and the analysis of salivary metabolomics may help in identifying tumor specific biomarkers for early diagnosis and prediction of tumor progression. The aim of the study was to evaluate the clinical utility of salivary metabolites in oral leukoplakia and oral squamous cell carcinoma.
Methods: Salivary metabolomic profile of patients diagnosed with oral leukoplakia (n=21) and oral squamous cell carcinoma (n=22) were compared with apparently normal controls (n=18) using QTOF- liquid chromatography mass spectrometry. Read More

Oncologic relevant members of S100 proteins are described as promising biomarkers in molecular pathology for risk estimation in oral neoplasia exhibiting different stages of malignancy: gingiva as healthy tissue, irritation fibroma as benign, leukoplakia as precancerous, and oral squamous cell carcinoma as malignant entity. Gene expression levels of S100A4 (metastasin), S100A7 (psoriasin), S100A8 (calgranulin A), and S100A9 (calgranulin B) were analyzed using quantitative RT-PCR. In addition, immunohistochemistry-based microscopy was used to examine cellular localization and distribution of these biomarkers in tissue sections. Read More

Background: Risk factors such as chronic use of tobacco, smoking and alcohol consumption of individual's lifestyle may possibly influence the significant role in the etiopathogenesis of precancerous lesions (PL) and Conditions (PC) and lead to oral cancer. Previous studies have revealed that genetic factors have contributed to a remarkable extent in the development of this chronic disease. Limited studies have confirmed that ABO blood groups remain reportedly possible genetic factor to the specific disease such as oral malignant. Read More

It is imperative for dermatologists to be able to recognize suspicious lesions, determine biopsy need, counsel, and refer patients presenting with premalignant or malignant conditions appropriately. Given the higher rates of mortality and morbidity of oral mucosal malignancies due to late diagnosis, appropriate treatment with multidisciplinary care in a timely manner is essential to these neoplasms.

A series of studies are dedicated to research the clinical outcomes of oral leukoplakia (OLK) treated with carbon dioxide laser (CO laser); however, the results vary from studies especially related to recurrence and malignant transformation. Hence, we performed this meta-analysis to precisely evaluate the malignant transformation of OLK dealt with CO laser and investigate the association between its malignant transformation and kinds of related risk factors, such as gender, clinical classification, long duration of leukoplakia, and degree of epithelial dysplasia and lesion regions. We performed a systematic search of the Cochrane Library, EMBASE, Pubmed, Web of Science, and SCOPUS. Read More

Tumor hypoxia is an important indicator of cancer prognosis. Among the different genes that are upregulated by hypoxia is carbonic anhydrase IX, which combines carbon dioxide and water to form bicarbonate and hydrogen. Although expression of this enzyme is very low in normal tissues, carbonic anhydrase IX is overexpressed in several types of cancer. Read More

Chronic ulcerative stomatitis (CUS) is a poorly understood disease with clinical and histologic overlap with lichen planus (LP). Unlike classic LP, direct immunofluorescence (DIF) studies in cases of CUS exhibit a granular pattern of IgG in nuclei of basal and parabasal cells. This study assesses the demographic, clinical, histologic, and DIF features of CUS. Read More

Objective: Information on patients with real or claimed adverse reactions towards dental materials in large patient cohorts is rare. Therefore, the aim of the present study was to investigate patients reporting on complaints and symptoms to dental materials over a 16-year period.
Methods: Five hundred patients were characterized by one single dental team regarding age and sex distribution, subjective complaints and objective intraoral symptoms, and allergy status relevant to dental materials. Read More

Research objective was assessment of a possibility of primary diagnosis of viruses Epstein-Burr, a cytomegalovirus, a virus of herpes of the 6th type in oral liquid and also influences of herpes infection on development and the clinical course of precancer diseases of the oral mucosa and the red border of lips (RBL). Profound clinic-immunological examination is conducted to 60 patients: the first group are have made 20 patients with an erosive and ulcer form of the lichen planus, the second - 20 people with an erosive form of a leukoplakia, a third - 20 people without diseases of the oral mucosa. As a result of work detection herpes infection is revealed high (90%). Read More

Infection and inflammation account for approximately 25% of cancer-causing factors. Inflammation-related cancers are characterized by mutagenic DNA lesions, such as 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG) and 8-nitroguanine. Our previous studies demonstrated the formation of 8-oxodG and 8-nitroguanine in the tissues of cancer and precancerous lesions due to infection (e. Read More

Objective: Fluorescence visualization devices are screening devices that can be used to examine lesions of the oral mucosa non-invasively. We observed oral squamous cell carcinoma (OSCC) and leukoplakia using the IllumiScan(Shofu, Kyoto, Japan) fluorescence visualization device and examined its usefulness and characteristics.
Methods: We investigated 31 OSCC and nine leukoplakia in patients who were examined using the IllumiScan and treated in our department from January 2017 to February 2018. Read More

Many oral diseases, such as oral leukoplakia and erythroplakia, which have a high potential for malignant transformations, cause abnormal structural changes in the oral mucosa. These changes are clinically assessed by visual inspection and palpation despite their poor accuracy and subjective nature. We hypothesized that non-invasive bioimpedance spectroscopy (BIS) might be a viable option to improve the diagnostics of potentially malignant lesions. Read More

Smokeless tobacco (SLT) use has many oral effects including oral cancer, leukoplakia and erythroplakia, oral submucous fibrosis (if mixed with areca nut), loss of periodontal support (recession) and staining of teeth and composite restorations. This review was aimed to provide information to identify oral lesions that occur due to the use of smokeless tobacco so that effective interventions can be undertaken to reduce morbidity and mortality from the use of SLT.
