Evaluation of immunohistochemical expression of epithelial- mesenchymal transition markers E-cadherin, Twist and Snail in oral submucous fibrosis and their possible association with malignant transformation.

Background: Oral submucous fibrosis (OSMF) is a chronic, potentially malignant condition of the oral mucosa, predominantly seen in people of Asian descent. The reported malignant transformation rate of OSMF is 7%-13%. In the context of the understanding progression of OSMF, the study of prime molecular expressions is essential.

"SKILL TO KILL" - Oral cancer and potentially premalignant oral epithelial lesions (PPOELs): A survey approach. Emerging of a new system and professionals.

Background: Oral cancer is said to be the 6th most common cancer in men and 12th in women. Potentially malignant disorders/potentially premalignant oral epithelial lesion (PMDs/PPOELs) have shown an increased risk of progressing to cancer. In this regard, lack of awareness about identification of oral PMDs among healthcare providers in general and oral pathologists in particular is said to be responsible for the diagnostic delay.

Quantification of in chronic periodontitis patients associated with diabetes mellitus using real-time polymerase chain reaction.

Introduction: Periodontal diseases, if left untreated, can lead to tooth loss and affect at least one tooth in 80% of adults worldwide, with the main cause being a bacterial plaque. Among subgingival plaque bacterial species, has been implicated as a major etiological agent causing tooth loss. Diabetics and smokers are two patient groups at high risk for periodontal disease.

Expression of CK14 and vimentin in adenomatoid odontogenic tumor and dentigerous cyst.

Background: Origin of adenomatoid odontogenic tumor (AOT) has long been a controversy, and the issue of it being a neoplasm or hamartoma was a subject of debate for a long time. Earlier it was grouped under a mixed group of odontogenic tumors considering the varying degrees of inductive changes. Recently, the WHO classification states that the presence of hard tissue within AOT was not due to induction but was rather a metaplastically produced mineralization and hence the tumor was reclassified under a group of tumors arising from odontogenic epithelium.

The synergy of tobacco and alcohol and glutathione S-transferase θ 1 gene deletion and oral squamous cell carcinoma.

Background: Oral squamous cell carcinoma (OSCC) is the leading cancer among males in India. It is related to tobacco habits and alcohol consumption as well as the individual susceptibility for xenobiotic metabolizing enzyme polymorphisms. Glutathione S-transferase θ 1 (GSTT1) is a Phase II metabolic enzyme which is directly involved in catalyzing chemicals to mutagenic intermediates.
