Abstract:
An apparatus for imparting mechanical forces onto a target surface, comprising:an electromagnetic energy source constructed to emit electromagnetic radiation along a propagation path extending distally away from the apparatus; anda fluid output adapted to place a distribution of non-flammable liquid particles within an interaction zone, the interaction zone extending a distance of about 5 mm or less along the propagation path;wherein the interaction zone is bounded at a proximal end thereof on the propagation path by an absence of fluid particles and is bounded at a distal end thereof on the propagation path by an absence of any substantial amount of electromagnetic radiation that would if present be capable of imparting burning cutting affects onto a tooth; andwherein a wavelength of the electromagnetic energy source is selected to be highly absorbed by the non-flammable liquid particles in the interaction zone, whereby the absorption of the electromagnetic radiation by the non-flammable liquid particles generates disruptive mechanical forces which are suitable for cutting the human-tooth.
