Article Abstract

Objective: The purpose of this study was to compare the difference of sexual hormone receptors' expression and distribution in the gingival tissues between periodontitis patients and normal females and to provide the theoretical facts for the clarification of periodontitis's pathogenesis.

Methods: The test group was 34 samples and normal control group was 30 samples. The test group and the normal control group were divided into 3 subgroups separately according to age. All specimens were studied for ER and PR proteins' expression using immunohistochemical techniques (Envision) uniformly, and observed by light microscope.

Results: ER and PR proteins located in cytoplasm or nuclear. ER and PR proteins' stainings occurred in the epithelium, the distribution of them had no regularity and staining intensity varied. The positive rates of ER and PR in the gingival tissues of normal female were low. The positive rate of ER in the gingival tissues of female with periodontitis soared apparently (P<0.01), but the positive rate of PR changed little (P>0.05).

Conclusion: The expression of ER in the gingival tissues might have relation to periodontitis of females. Besides acting indirectly on the gingival tissues, estrogen could affect the gingival tissues directly by ER; progesterone might have indirect effects on gingival tissues.
