The decementation of glass fiber post can be attributed to the degradation of collagen fibers by matrix metalloproteinases (MMP) at the level of the intra radicular hybrid layer. The objective of the research was to compare the tensile bond strength of glass fiber posts that were cemented with previous treatment of the radicular dentine with chlorhexidine at 2% inside the adhesive protocol. Thirty eight bovine incisives were employed. The specimens were then divided into two groups (n=19): control group (it were realized the conventional procedure) and experimental group (it were realized the application of chlorhexidine at 2% inside the adhesive protocol). The tensile bond strength was measured with an Amsler universal tester machine. The data were statistically process with the T Student test for establish important differences in the two groups (p – value < 0.05). We obtained a great increases in the values to the tensile bond strenght to the glass fiber posts when apply chlorhexidine at 2% as an additional step between the acid etching and the application of adhesive system.
