ABSTRACT
AIM:
To observe the expression of epidermal growth factor receptors(EGFR) of gingival tissue in periodontitis.METHODS:
The expression of EGFR was determined by using immunohistochemical techniques in gingival tissue of 15 healthy individual, 32 cases with adult periodontitis (AP) and 12 cases with juvenile periodontitis (JP).RESULTS:
Expression of EGFR was mainly located on basal cell membranes in healthy gingiva, and the staining intensity was faint. In AP cases, expression of high level EGFR was mostly observed on the membranes of epithelial cell in the periodontal endopocket or junctional epithelium, intensity of staining appeared to decrease gradually with the differentiation of keratinocytes, and the horny cell layer was not stained by the antibody. In JP cases, strong positive staining was present on membrane of epithelial cells in the germinative layer of gingival tissue. There was an apparent difference between healthy gingiva and AP or JP (P< 0.01 ), or AP and JP (P< 0.01).CONCLUSION:
The distribution and expression of EGFR in gingival epithelium of periodontitis showed obvious differ- euce. The data indicated that EGFR may affect apical migration of junctional epithelium, and may play a role in development of AP and JP.
