Claim 34:
35. An apparatus for removing organic material from a treatment region of a tooth, comprising:
a fluid source arranged to deliver a substantially gas-free liquid to the treatment region;
an enclosure having a mounting surface configured to be positioned against a tooth surface over the treatment region of the tooth, the enclosure configured to define a chamber to be filled with the substantially gas-free liquid when the enclosure is positioned against the tooth; and
a pressure wave generator coupled with the enclosure, the pressure wave generator configured to direct a coherent, collimated energy beam, through the delivered liquid to propagate pressure waves through the delivered liquid, the coherent, collimated energy beam comprising a liquid jet,
wherein the pressure waves have sufficient energy to cause organic material in the treatment region to be detached from surrounding dentin when the substantially gas-free liquid is at the treatment region,
wherein the pressure wave generator comprises a liquid jet device, wherein the liquid jet device comprises a liquid pressurization portion which pressurizes the liquid and a liquid beam forming portion in fluid communication with the pressurization portion, said beam forming portion comprising an orifice that receives the pressurized liquid, said orifice sized and shaped to convert the pressurized liquid into the liquid jet.
