OBJECTIVES Oral submucous fibrosis (OSMF) is a potentially malignant disorder of oral cavity, pharynx and upper digestive tract, characterized by progressive inability to open the mouth. Based on clinical and/or histopathological features, various classifications and grading systems have been put forth till date. The aim of the present study was to study the variance in cheek flexibility in OSM...

BACKGROUND Oral submucous fibrosis (OSF) is an insidious chronic condition characterized by restricted mouth opening. Prosthetic rehabilitation is challenging for OSF patients as obtaining a good impression requires adequate mouth opening. The aim of the present review is to systematically present the data from case reports published in the English-language literature. METHOD A comprehensive ...

BACKGROUND Oral submucous fibrosis (OSF) is a common oral health problem in the Indian subcontinent. It is characterized by a juxtaepithelial inflammatory reaction followed by fibroelastic changes in the lamina propria. Traditionally, it is said to be associated with marked epidermal atrophy and decreased vasculature as the disease advances. OBJECTIVE To assess the changes in epidermal thickn...

AIM To describe a novel neural network based oral precancer (oral submucous fibrosis; OSF) stage detection method. METHOD The wavelet coefficients of transmission electron microscopy images of collagen fibres from normal oral submucosa and OSF tissues were used to choose the feature vector which, in turn, was used to train the artificial neural network. RESULTS The trained network was able ...

Context: Oral squamous cell carcinomas develop from a premalignant lesion or condition, which are due to a variety of aetiological factors. Early detection of these are necessary to prevent them from developing into carcinomas which can increase the mortality and morbidity. There are a variety of possible aids like histopathology, Hstiochemistry and Enzyme assays in diagnosing these lesions. Hi...

Verrucous carcinoma (VC) otherwise known Ackerman’s tumor is a distinct variety of epidermoid carcinoma with characteristic clinical presentation, behavior and histological features. It usually presents as a hyperplastic epithelium, abundant keratin superficially with a church-spire keratosis and also presenting parakeratin plugging which is characteristic of this VC. Oral squamous cell carcino...
