We all are aware of lasers now. They have been affecting our lifestyle to a great extent. But, have you heard of cold lasers? The latest Buzz word in laser dentistry is “Cold Laser” or Soft lasers. The cold lasers are the powerful lasers which are defocused to make the tissue interaction as biostimulation and hence the scientific name as Biostimulatory lasers.
Receptors in plants are well known. But do you know that there are receptors in human body as well which are responsible for the laser light to be absorbed. Photochemically reactive proteins which are responsible for harvesting low light energy are present in abundance in human body. Out of more than 300 proteins in human body, the most common receptor proteins are the rod and cone pigments in eye. The photoreactive molecules in a cell are called Chromophores.
The soft lasers or the cold lasers do not vaporise or cut the tissue. The cell with impaired function gets stimulated when the laser light is administered in right dose. When the laser light falls on cells, the chromophores result in formation of radical oxygen species. ATP or Adenosine Tri-Phosphate, fuel molecule of a cell is influenced by redical oxygen species. At certain level of ATP, the cell metabolism increases and there is enhanced RNA and DNA formation in nucleus of cell. All these things, convert into a faster healing. The important point to note here is that the soft tissue heals at a fast pace post-surgery. The cold lasers are now a renowned name in dentistry as well as medicine as it is associated with tissue healing.
