Physical Effects On The Interactions Of CO2 Laser On The Teeth

Recent studies have shown that CO2 lasers can successfully be used at low-power densities to fuse enamel, dentin, and apatite. In this study, forty nine samples of different types of extracted human teeth were irradiated under low power continuous wave CO2 laser. The mass, density, and thickness of...
