A dental syringe is constructed as an assembly of which the handle, head and tip components, which together include substantially all of the exterior surfaces of the syringe, can be quickly detached from an internal cartridge, which is connected to the utility conduits. The cartridge is constructed to close off the utility lines when it is detached from and to open the utility lines when it is connected to the remainder of the assembly.
