Abstract: Embodiments include an apparatus for use in the dental field including a cannula, the cannula including, a first hollow tubular branch, a second hollow tubular branch, a hollow tubular arcuate portion connecting the first hollow tubular branch and the second hollow tubular branch, a first hollow tubular member, a second hollow tubular member forming an elbowed portion, at least one first aperture formed on a relief feature of the first hollow tubular branch, at least one second aperture formed on the second hollow tubular member.

Abstract: A cannula for evacuating irrigation fluid, saliva and/or blood for use in the dental field is formed of three interconnected tubular conduits and includes two hollow tube members one of which includes a first aperture formed on a buttressed plate parallel to the first tubular member, a second aperture being located on an upper part of the distal portion of the second tubular member allowing simplified placement and removal by engaging forceps in the apertures and use of the cannula with a first branch of the cannula inserted between the teeth and the tongue of a patient and the second branch of the cannula inserted between the teeth and the cheek of the patient.
