Histochemical analysis of polarizing colors of collagen using Picrosirius Red staining in oral submucous fibrosis.
BACKGROUND Oral Submucous fibrosis (OSMF) is a common potentially malignant disease, which is characterized by generalized fibrosis of the oral soft tissues. It is due to disproportion in the collagen deposition and degradation. The excess deposition of collagen results in juxta epithelial fibro elastic changes and epithelial atrophy. Neoplastic changes in the epithelium usually precede the cha...
متن کاملOral Submucous Fibrosis: A Chronic Deliberating Disease of Oral Cavity
Oral submucous fibrosis is chronic progressive condition of oral cavity. The condition is well recognized for its malignant potential. Usually the disease initiates with redness, blistering, and ulceration inside the mouth. It is characterized by progressive fibrosis of submucosal tissue. The pathogenesis of oral submucous fibrosis is not well understood. Betelquid chewing is the major etiologi...
متن کاملOral Submucous Fibrosis: a case report
We describe an interesting case of oral sub mucous fibrosis accompanied by severe trismus in a 23 years old man. The patient had initially been diagnosed as having internal derangement of the temporomandibular joint and conservative treatment had failed to decrease the symptoms. Despite extremely limited temporomandibular joint movement, cone beam computed tomography revealed no important abnor...
متن کاملComparative Study of Clinical Staging of Oral Submucous Fibrosis with Qualitative Analysis of Collagen Fibres Under Polarized Microscopy
Background & Objectives: Oral submucous fibrosis (OSMF) is a condition where excessive deposition of dense collagen fibers occurred in the connective tissue of oral mucosa. An alteration of collagen necessitates an in depth understanding of collagen in oral tissues as no breakthrough studies have been reported. Therefore the aim was to correlate the clinical, functional and histopathol...
متن کاملCollagen biosynthesis in human oral submucous fibrosis fibroblast cultures.
To investigate the mechanism of collagen accumulation in oral submucous fibrosis (OSF) tissues, we examined the biosynthesis of collagen in fibroblast cultures established from OSF lesions. Fibroblasts obtained from four of ten OSF specimens showed more than a 1.5-fold increase in the production of collagens compared with fibroblasts from age-, sex-, and passage-matched normal controls (p < 0.0...
