Cell adhesion , Titanium , Titanium alloy , Shear stress We examined the effects of nitric acid and heat treatments on titanium and Ti − 6 Al − 4 V alloy by measuring the dynamic contact angle , relative cell adhesion rates after l h( , ur and 24 hours, and the cellular adhesive strength of L − 929 cells using a cone and disk type viscometer . The dynamic contact angle was not influenced by 40 % nitric acid , but was decreased by heat treatment. The relative cell adhesion rate after each

However , there was no difference in the percent of adherent cells with changes in the experimental conditions . Thus , a method other than contact angle should be used to evaluate cell adhesive strength .
