Objective: Reproducibility of qualitative changes in histopathological diagnosis involving narrow variation is often challenging. This study aims to characterize the histological fibrotic events in detail so as to derive an in-depth multiparametric algorithm with individually quantified histological parameters for effective monitoring of the. disease process in oral submucous fibrosis and for potential therapeutic targets for early intervention. Methods: Formalin fixed paraffin embedded (FFPE) blocks of oral submucous fibrosis (OSMF), were taken and sections were stained with Hematoxylin & Eosin stain and Masson Trichrome stain. Photomicrographs were assessed for various morphometric parameters with Image J software version 1.8. Linear Regression was used to model the relationship using Inflammatory Cell Count, Extent of Inflammation collagen stained area, Epithelial thickness integrated density of collagen, MVPA, Area, Perimeter, were taken as variables. Result: Inflammatory cell count and the extent of inflammation also decreased with increasing grades of OSMF. Collagen proportionate area, integrated collagen density and epithelial thickness were compared among different grades of OSMF. Grade IV OSMF had greatest mean collagen proportionate area , highest integrated collagen density and lowest epithelial thickness when compared to other grades of OSMF. Linear regression model revealed smaller variation between Grade I to Grade II. Whereas Grade II to Grade IV exhibited larger variation suggestive of increased growth rate and all the coefficients were found to lie within 95% confidence limits Conclusion: Diagnostic algorithm with multiparametric regression model were derived and combinatorial therapeutic approaches have been suggested for more effective management of oral submucous fibrosis

Background: Reactive oral lesions pose diagnostic difficulties as they mimic each other clinically. A definitive diagnosis is made based on the histopathological presentation of this group of lesion. Stromal microenvironment is the key to the sequence of the stages of these lesions. Stringent quantification of each component of the stroma is important to understand the pathogenesis. The aim is to evaluate inflammation, angiogenesis, and fibrosis in the reactive group of lesions through quantitative analysis. Materials and Methods: Blocks of irritation fibroma, inflammatory fibrous hyperplasia, pyogenic granuloma, and normal mucosa were retrieved from the archives and Hematoxylin and Eosin (H&E) and Masson Trichrome staining were done. The severity of inflammation, epithelial thickness, collagen proportionate area, integrated density of collagen, Mean Vascular Area (MVA), Mean Vascular Perimeter (MVP), and Mean blood vessel percentage area (MBVPA) were analysed quantitatively using Image J software version 1.8. The pattern of rete ridges at the epithelium-connective tissue interface was analysed qualitatively. Results: Inflammatory fibrous hyperplasia presented with severe inflammation (60%). Mean Vascular Percentage Area (MVPA) and Mean Vascular Perimeter (MVP) were increased in pyogenic granuloma. The mean collagen proportionate area and the integrated density of collagen were found to be more in irritation fibroma (64.47%, 2519638.01 ± 810471.58 μm2). The epithelial thickness was highest in inflammatory fibrous hyperplasia (62.71 ± 18.86 μm). Conclusion: Reactive oral lesions are histologically distinct, yet they exhibit considerable overlap depending on the stage of the lesion. A morphometric quantitative exploration of the individual pathogenic components may aid in specific diagnosis.

Objective: To evaluate the anti-carcinogenic effect of Centella Asiatica on to evaluate the Anti-Carcinogenic Effect of Centella Asiatica on Oral Cancer Cell Line oral cancer cell line. Materials and methods: Oral Cancer cell line and normal oral keratinocyte cell line were procured.Centella asiatica extract was prepared. The cells were then subjected to the test herbal specimens -Centella asiatica extract in succeeding concentrations of 25 µg/ml, 50 µg/ml, 100 µg/ml at time intervals of 24,48 and a72 hours. Cisplatin (2 µg/ml, 4 µg/ml, 6 µg/ml, 8 µg/ml) was used as a positive control. This experiment was done in triplets. Results: The study revealed that the p values were less than 0.05 at concentration 12.5µg/ml, 25µg/ml, 50 µg/ml,100 µg/ml and time period of 24hrs,48hrs,72hrs, thus implying that at these concentrations and time period, the obtained data were statistically significant, thus indicating that there is a statistically significantly decreases in the viable cells as the concentration of the drug as a time period increases The results reveals that centella asiatica possess potential effect of anti-carcinogenic, effect when compared to positive control (Cisplatin). Conclusion: The current study reveals that Centella asiatica has an potential anti-carcinogenic effect on oral cancer cell line. So this can be used to treat oral cancer with minimal crippling as compared with allopathic drugs.
