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 histopathologica...
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...
Objectives. The present study was done to evaluate birefringence pattern of collagen fibres in different grades of oral squamous cell carcinoma using Picrosirius red stain and polarization microscopy and to determine if there is a change in collagen fibres between different grades of oral squamous cell carcinoma. Materials and Methods. Picrosirius red stained 5 μm thick sections of previously d...
OBJECTIVES The aim of the present study was to perform a stereological and biochemical analysis of the foreskin of smoker subjects. MATERIALS AND METHODS Foreskin samples were obtained from 20 young adults (mean = 27.2 years old) submitted to circumcision. Of the patients analyzed, one group (n = 10) had previous history of chronic smoking (a half pack to 3 packs per day for 3 to 13 years (me...
BACKGROUND WHO has recently renamed odontogenic keratocyst as keratocystic odontogenic tumour (KCOT) depending on its tumour like behaviour. AIM To quantitate and qualitate different types of collagen fibers in KCOT using picrosirius red stain under polarising microscopy and to correlate with different radiographic patterns of KCOT to elucidate its biological behaviour in order to determine w...
