To know the proper functioning of Laser dentistry, we should first know the effect a Laser beam will be having on our human body tissue.
Laser acts by focusing a beam of Laser light on water molecules present in tissues to bring about the following changes in the human tissue:
Effects of Laser on Human/ Oral Tissue – Laser Dentistry:
- 37-50 degrees – Hyperthermia
- 60 degrees – Coagulation protein denaturation
- 70-90 degrees – Welding of tissue
- 110 – 150 degrees – Vaporization
- > 200 degrees – Cartonization
The effects are divided based on changes in temperature so before using laser we should have the proper knowledge to set the temperature to optimum level to bring about the desired change in out dental procedure.
Types of Lasers used in Dentistry:
- Gas Lasers: CO2, HeNe, Excimer, Ion Lasers
- Semi Conductor – Diode Lasers: Argon Lasers
- Dye Lasers: Rhodamine 6G
- Solid State Lasers: Nd: YAG Lasers, Er: YAG lasers, Er.Cr: YSGG laser, Ho: YAG laser, KTP laser
Dental Lasers have to be divided based on their action of Soft Tissue (gingiva, Oral mucosa, Pulp) and Hard Tissue (Enamel, Dentin, Alveolar Bone)
