Claim 0:
1. A method for treating a hard dental tissue, the method comprising the steps of:
generating a laser beam using a laser source;
directing the laser beam to a treatment surface of the hard dental tissue using an optic in optical communication with the laser source, wherein the laser beam comprises a spot size at the treatment surface in a range from 0.2 mm to 5 mm;
controlling the laser source and the optic using a controller to deliver the laser beam to the treatment surface to treat an area of the hard dental tissue at a rate in a range from 10 cm2/min to 20 cm2/min with a fluence in a range from 0.4 J/cm2 up to 1.2 J/cm2 to:
remove at least some carbonate from the treatment surface to generate an acid resistant surface without damaging the hard dental tissue;
thereafter determining a depth mineral loss (ΔZ) value of the hard dental tissue; and
confirming the ΔZ value of the hard dental tissue is at least 10% lower relative to untreated hard dental tissue.
