Abstract: Objective: To measure the tensile bond strength of homemade Chinese herb denture adhesive,and compare with Protefix denture adhesive. Methods: The homemade denture adhesive and the Protefix denture adhesive were soaked in artificial saliva for 12 h, during which the the tensile bond strength of them were tested horary. Statistical analysis was performed by SPSS13.0. Results: The tensile bond strength of two types of denture adhesives values were not significant different before they were soaked in artificial saliva (P>0.05). After immersed in artificial saliva, the tensile bond strength of the homemade Chinese herb denture adhesive were significantly stronger than Protefix denture adhesive in terms of the maximum value, the average value and the value of 12h (P<0.05). Conclusion: The homemade Chinese herb denture adhesive was good adhesive properties.
