A dispensing syringe for dispensing a multi-component dental composition, preferably a two component composition, is provided. The syringe includes a syringe body with multiple elongated barrels for storing the components of the composition a threaded plunger rod assembly and a rotatable, threaded connector knob. Preferably, the syringe body has a double- barrel structure and the plunger rod assembly includes two plunger rods that slide within the barrels. The threaded knob has a through-bore with a continuous internal thread for engaging the outer threads of the first and second plunger rods. A dental practitioner manually rotates the knob to displace the first and second plunger rods and discharge the components. The dispensing syringe may further include a dispensing tip containing a static mixing element for mixing the components and dispensing the mixed composition.
