Abstarct: The aim of this study was to compare the effect of plasma jet and plasma dielectric barrier discharge on tendon tissue repair. Achilles tendon rupture is common and has increased greatly in the last decade, as the repair of this type of injury is slow and the use of new methods such as cold plasma is essential. Plasmas can be classified according to configuration and working gas. According to this classification, plasma jet and dielectric barrier discharge plasma are two important types of plasma that have played an important role in treatment. In two types of plasma, voltage factors and electrode type are effective in the rate of repair. In order to achieve the best repair conditions, both types of plasma were placed at voltages of 5, 10 and 15 kV and then copper, steel and zinc electrodes were installed in both types of plasma. Factors such as length, emission spectrum, temperature and density, flow were calculated and standard doses were applied to the tissue. The results showed that plasma is not formed at voltages of 5, 10 and 15 kV using aluminum electrodes. Jet plasma and FE-DB plasma are not formed with steel electrode at 5 kV. As the voltage increases, the length, temperature, density, power and current in the plasma increase. Also, these factors are reduced in copper and steel electrodes, respectively. The results showed that the repair process in both plasma is the same but the recovery rate is different. Dielectric barrier discharge plasma is more efficient than jet plasma. The highest rate of repair was observed in the discharge plasma of the dielectric barrier with a applied voltage of 15 kV and with a copper electrode.
