ABSTRACT
Objective:To quantify the tryptase and T cell immunoglobulin mucin domain-3(TIM-3)double positive mast cells in hu-man chronic periodontitis tissue using double immunofluorescence staining.Methods:25 healthy controls,28 chronic mild periodontitis and 30 chronic advanced periodontitis patients were included.The gingival specimens were stained with HE for histology,and with double immunofluorescence staining for the identification of tryptase and TIM-3 double positive mast cells in gingival tissue.Results:In chronic periodontitis tissue the degree of gingival inflammation was significantly increased,the densities(cells/mm2 )of tryptase and TIM-3 double positive mast cells were significantly increased(P<0.05),in addition,that in chronic advanced periodontitis group was significantly higher than in the chronic mild periodontitis group(P<0.05).Conclusion:Tryptase and TIM-3 double positive mast cells has the similar tendency as the severity of periodontitis inflammation in human periodontitis tissue.Tryptase and TIM-3 double positive mast cells may play an important role in human chronic periodontitis.
