Septodont Endomethasone N is a dental material specifically designed for permanent root canal filling and sealing. It consists of a liquid and powder component that combine to form a reliable and effective paste. This paste possesses essential properties for successful root canal treatment. It offers excellent non-resorbable characteristics, ensuring stability and longevity of the filling. Its non-retractable nature maintains shape, providing a secure seal within the root canal to prevent bacterial entry and treatment failure. The material is radiopaque, and easily detectable on dental X-rays for accurate monitoring of the filled root canal. Additionally, Endomethasone N contains hydrocortisone acetate, providing anti-inflammatory activity to promote healing and enhance treatment success. To use Endomethasone N optimally, the treated tooth should be isolated, and the canal shaped, cleaned, rinsed, and dried. The paste is prepared by mixing the powder progressively into the liquid at a specific ratio. Various filling techniques can be employed, such as using a paste carrier or coating Gutta-Percha points for condensation techniques. Regular X-rays should be taken to ensure thorough filling. To maintain its quality, Endomethasone N should be stored below 25?C and protected from moisture.
