Background: Odontogenic cysts and tumors are most common benign destructive lesions in the oral cavity. These cystic lesions with its central fluid, reservoir of non-physiological composition, is in itself likely to provoke an inflammatory response in the surrounding host tissues, which may result in its formation and enlargement. Aims and Objectives: 1. To evaluate the number of mast cells and eosinophils in radicular cyst, keratocystic odontogenic tumor and dentigerous cyst and to intercompare it with the degree of inflammation. 2. To evaluate and intercompare the staining quality of toluidine blue and thionin for mast cells identification and Carbol Chromotrope and Congo red for eosinophils evaluation. Study Design: The study comprised of total 47 cases of which 20 were of radicular cyst, 15 were keratocystic odontogenic tumor and 12 were dentigerous cyst. Sections of 4μm thick were cut and stained with gold standard hematoxylin and eosin staining procedure for routine diagnosis. The amount of inflammation in each cyst was graded. They were further stained with toluidine blue and thionin for mast cells identification and Carbol Chromotrope and Congo red for eosinophils identification. The statistical analysis used was one way ANOVA (Analysis of Variance) and Pearson's Correlation Coefficient. Results: The mean number of cell count per high power field of mast cells was higher than the eosinophils. On correlating with degree of inflammation the results came out to be statistically significant. The staining quality for mast cells was equally good with toluidine blue and thionin, whereas Carbol Chromotrope had a significantly better staining quality than Congo red in case of eosinophils. Conclusion: The higher number of mast cells detected in odontogenic cysts could contribute in the release of inflammatory mediators involved in the pathogenesis of odontogenic cysts formation and enlargement. The histochemistry using various stains has proved to be promising in identification of mast cells and eosinophils.
