Dental syringe tip devices, systems and methods

A method of preparing a syringe tip for attachment to a dental syringe, the method comprising:

• providing an outer core having a proximal end and a distal end, the outer core having a first passage and a second passage that are spaced apart and parallel to each other, each of the first and second passages having a proximal aperture at the proximal end of the outer core, and a distal aperture at the distal end of the outer core;
• providing a first inner core configured to be received and retained within the first passage of the outer core, the first inner core having a proximal end and a distal end, the first inner core having a first proximal aperture at the proximal end of the first inner core, a first distal aperture at the distal end of the first inner core, and a first passage connecting the first proximal aperture and the first distal aperture;
• providing a second inner core configured to be received and retained within the second passage of the outer core, the second inner core having a proximal end and a distal end, the second inner core having a second proximal aperture at the proximal end of the second inner core, a second distal aperture at the distal end of the second inner core, and a second passage connecting the second proximal aperture and the second distal aperture;
• providing a carrier with two holders configured to receive the first and second inner core;
• providing a connector to provide a third passage through a top, bottom, or lateral surface of the outer core such that the third passage is in fluid communication with the first passage of the outer core, the connector provided at a location other than the proximal and distal end of the outer core;
• inserting the first inner core into the first passage of the outer core;
• inserting the second inner core into the second passage of the outer core;
• coupling the carrier with the first inner core and the second inner core;
• and
• engaging a clip mechanism of the carrier with a corresponding recess on the outer core.
