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.
Claims7
A method for treating a root canal in a tooth, the method comprising:
- providing a liquid to a treatment region of the tooth including an infected or decaying portion;
- submerging a conical application tip of an elongate optical fiber in the liquid;
- operating a laser source to generate a laser light beam and transmit the laser light beam along the elongate optical fiber to the submerged conical application tip;
- and
- irradiating the liquid in the tooth using the laser light beam to clean the treatment region of the tooth via a photoacoustic effect while the conical application tip is submerged in the liquid, the conical application tip directing at least a portion of the laser light beam laterally outwardly into the treatment liquid, the laser light beam emanating from the conical application tip having sufficient power to create photoacoustic waves in the liquid of sufficient vibrational energy to remove at least organic material from a portion of a wall of the root canal.
