Expression of apoptosis regulatory proteins p53, bcl-2 and bax in recurrent aphthous ulceration

Abstract

Background  Recurrent aphthous ulceration (RAU) is considered to be an acute inflammatory disease of unknown pathogenesis. Apoptosis may represent an important event in the control of inflammation.


Objectives  The aim of this study was to investigate apoptosis process in RAU using immunohistochemistry.


Methods  We studied the expression and location of p53, bcl-2 and bax in ulcerated lesions clinically diagnosed as RAU (n = 12) and compared it with that of oral clinically normal mucosa (n = 6) and of other inflammatory chronic disease such as oral fibrous inflammatory hyperplasia (FIH; n = 18).


Results  Significant statistically differences (n < 0.05) in ...
