Abstract: A method treating a root canal in a tooth by introducing into the pulp chamber of a tooth and pulsing a laser light into the fluid reservoir so as to disintegrate pulp within the root canal without generation of any significant heat in said liquid fluid so as to avoid elevating the temperature of any of the dentin, tooth, or other adjacent tissue more than about 5? C.

Abstract: The specification discloses embodiments and other information concerning methods, systems, and apparatus in accordance with aspects of the subject invention for treating diseased root canals in teeth and other dental condition, such as periodontitis and the like wherein a laser light is pulsed from a laser fiber optic tip into liquid contained in a reservoir or other space within the canal, periodontal sulcus/pocket, or other dental space immersing the area in need of treatment so as to disintegrate, separate, or otherwise neutralize pulp, plaque, calculus, bacteria, and other microbes, thus annihilating and particleizing undesirable material within the liquid in the reservoir by the action of relatively intense, photoacoustic micro-pressure waves propagating throughout the liquid as a result of the laser light pulses emitted into the liquid from the tip, thereby enabling easy removal of the particles by finely dispersing the same in the liquid and then flushing the particle-laden liquid from the area by hydr
