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: A method that includes the following effects: the ability to expand, porositize, clean, decontaminate, debride, break-down and/or destroys, or aids and accentuates the dissolution or extraction of biological structures, nerves and tissues. The methodology uses nano-technology and/or other chemistries may or may not be excited by energy sources to expand and porositize the tissue, which enhances the penetration and effectiveness and acceleration of subsequent chemical, mechanical, and/or procedural steps in the protocol or process. Furthermore, the method includes the ability to associate with and/or initiate in the reconstructive growth and healing process associated with healthy tissue after surgery and/or the ability to destroy diseased or necrotic tissues or cells.
