We have many lasers that we use with different wavelengths. I started using a CO2 laser about 16 or 17 years ago and that has value to us in terms of laser being a bit more efficient than using a scalpel blade. It allows us to get a quicker healing time, a nicer healing phase. It allows us to do things with a laser that normally we wouldn’t be able to do without, and it just has multiple uses within periodontal treatment, with biopsy treatments. There’s many uses and we have different lasers for different uses.
