This paper studies of the effect on surface characteristics of bone surface after plasma treatment. For that purpose, the experimental procedure is designed to develop atmospheric plasma jet device. The physical processes such as electron dynamics, electron field, ionization and dissociation in relation to atmospheric pressure plasma are stated. The plasma jet is ignited in a glass tube with helium gas flowing freely into the surrounding air. Some consideration to develop the plasma jet is made to get stable plasma. In addition, its focuses on the surface analysis for bone surface after being treated to plasma. A few samples of freeze dried bovine bone were radiated in plasma. Then, the surfaces of bone were characterized in the term of surface morphological changes by using Scanning Electron Microscopy (SEM) and the data were analyzed to observe it differences. From the results of SEM, we could confirm that the main phenomena such as the reactive etching has modified the surface morphology.
