Laser is an acronym for Light Amplification by the Simulated Emission of Radiation. Lasers are the latest tools in Dentistry that can either be used alone or as an adjunct to tradition modalities. Laser produces a very narrow intense beam of light energy that when comes in contact with a tissue (soft or hard) causes a reaction. Broadly two types of lasers are used in Dentistry; hard tissue lasers and soft tissue lasers.
- Hard Tissue Lasers: As the name suggests this is used for hard tissues such as teeth. It cuts through bone and water specifically the calcium phosphate in bone and teeth.
- Soft Tissue Lasers: It uses a shorter wave length that haemoglobin & water can easily absorb and can be used for soft tissues.
Lasers in Dentistry have a wide range of utility:
- Cosmetics: Extensively used for bleaching and whitening of teeth without causing sensitivity; Crown Lengthening Procedures; Reshaping Gums to create a more aesthetic smile.
- Endodontics: Used extensively in Root Canal Treatment; used in Pulpotomy. Can also be used in Apicectomy and Root Amputation.
- Periodontics: To treat gingival inflammation and infections involving the Periodontium. It is used in combination with traditional methods in flap surgery like Gingivectomy and Gingivoplasty. They are also used as a sulcular debridement agent to aid in Curettage Procedures.
- In detection of cavities and removal of decay within the tooth; used to prepare the enamel to receive filling as well as to aid in retrograde root fillings.
- Used in treatment of soft tissues disorders such as ;
-In the treatment of aphthous ulcers
-In Pericoronitis (for Oporculectomy)
-To treat minor tongue restrictions
