Abstract
A method for treating dental hard tissue to decrease sensitivity by occluding dentin tubules. A CO2 laser source generates a pulsed laser beam having a wavelength of 9-11 microns. A laser beam width is defined and the pulsed laser beam focused at or near the dental hard tissue. A pulse energy is controlled with at least one beam pulse having a fluence profile in a working range of the laser beam having:
- a maximum local fluence less than a minimum fluence that causes damage of the dental hard tissue, andat least one other local fluence greater than a fluence that causes a minimum amount of occlusion of the dentin tubules.The pulsed laser beam is directed to respective dental hard tissue locations to occlude the dentin tubules, without delivery of cooling fluid while directing the pulsed laser beam to respective tissue locations.
