				        	AIM:To identify and quantify the expression of IL-1βand IL-17 in mast cells ( MCs) in different types of human pericapical diseases using double immunofluorescence staining .METHODS: The specimens ( n=102 ) , including healthy control ( n=35 ) , periapical cyst ( n=35 ) and periapical granuloma ( n=32 ) , were involved in the present study .The tissue samples were fixed in 10% buffered formalin for at least 48 h and then embedded in paraffin . Serial 5-μm-thick sections were deposited onto SuperFrost/Plus microscope glasses .Routine staining of the sections using hematoxylin&eosin ( HE) was performed for morphological evaluation .The number of IL-1βand IL-17 positive MCs was identified by double immunofluorescence staining .RESULTS:Compared with the healthy controls , the inflammation score of periapical lesions was significantly increased in the periapical patients (P<0.01).The density of IL-1βand IL-17 posi-tive MCs in the periapical lesions were obviously higher than that in the healthy controls (P<0.01).However, no signifi-cant difference between periapical cyst and periapical granuloma was observed .The Pearson correlation analysis showed that there was a positive correlation between the density of IL-1βand IL-17 double positive MCs and inflammation score in dif-ferent groups of specimens (P<0.01).CONCLUSION:There is significantly increased number of MCs , along with in-creased density of IL-1βand IL-17 positive MCs in human periapical lesions .The increased density of IL-1βand IL-17 positive MCs has the similar tendency as the severity of tissue inflammation in human periapical lesions , suggesting that IL-1βand IL-17 positive MCs may play an important role in the pathogenesis of human periapical diseases .
