Laser is an acronym for “Light Amplification by Stimulated Emission of Radiation”. Laser Dental Surgery uses a concentrated beam of intense light to correct dental problems. Laser Dentistry can be used during a number of soft and hard tissue procedures, in the areas of General Dentistry, Cosmetic Dentistry and Restorative Dentistry. Initially laser was used for ablating the hard tissues for acid etch treatment. Later, Lasers were used for cutting, coagulation & cauterization of the soft tissues. It is also been used for the diagnosis of carious lesions& to test pulp vitality with Doppler. There are more than 40 uses for Laser. Initially Lasers were very expensive, but now they have become much cheaper. Portable models are available which have increased its versatility. The laser sterilizes and coagulates blood vessels at the same time, thereby reducing the opportunity for infection. Lasers in dentistry can be used for surgical procedures such as a cutting instrument or tissue vaporizer, meaning it melts away tissue it comes in contact with.
Types of Laser used for Laser Dental Treatment
Lasers produce light of a specific wavelength; each wavelength interacts with different substances in its own unique way. Laser’s specific wavelength can be used to create a specialized interaction with the tissues.
The main kinds of dental lasers include;
Diode and Nd:YAG: Lasers target diseased tissue; wavelengths target the pigments in soft tissue and pathogens such as Porphyromonas gingivalis, as well as inflammatory and vascularized tissue. a diode laser gives off a wavelength that is very good at cutting gum tissues with little to no bleeding. It can also be used with special bleaching agents to whiten teeth.
Carbon-Dioxide Lasers: Carbon-Dioxide Lasers works well in soft tissue, also easily interact with free water molecules in soft tissue, as well as vaporize the intracellular water of pathogens.
Erbium Lasers: Erbium Lasers works well in both soft and hard tissue are sometimes called “all tissue” instruments because of their excellent absorption in both apatite crystals and the water of soft and hard tissue.
Argon Lasers: Finally, an argon laser produces a blue-green light that can be used to cure filling materials, perform bloodless surgery, detect decay or cracks in teeth, and even bleach teeth when used with specific bleaching gels.
Uses of Lasers in Dentistry
The rapid advancements in laser technology have been introduced into various fields of dentistry.
Some of the present applications of laser in dentistry are as follows,
a) Detection of pulp vitality
Low level laser therapy (LLLT)
b) Laser fluorescence - detection of caries, bacteria and dysplastic changes in the diagnosis of cancer
Hard Tissue Applications
Hard tissue includes treatments such as cavity detection, dental fillings, and improving tooth sensitivity. Other treatments include;
Caries removal & cavity preparation
Recontouring of bone (Crown lengthening)
Endodontics Root canal preparation, sterilization and apicoectomy
Soft Tissue Applications
Soft tissue treatments include gum reshaping, gum surgery, and improving muscle attachment.
Procedures such as removing benign oral cancers, nerve regeneration, overcoming sleep apnea, teeth whitening, and TMD treatment are also considered laser dentistry treatments.
Laser Dental Treatment Procedure
The dentist will decide which type of laser is best to use after conducting X-rays and a thorough examination. The laser beam is extremely bright, and special glasses will be provided to protect the eyes. The dentist will then direct the beam at the affected area and carefully dissolve the soft tissue, harden the filling or whiten the teeth. There are two basic emission modes for dental lasers - continuous-wave and free-running pulsed. Laser dentistry differs from traditional dentistry in that it is far less invasive. Many dental procedures with dental laser can be completed in minutes; especially matters like teeth bleaching and decay removal.
Because of the precision of a dental laser, much less work is actually done in the mouth. This reduces the need for uncomfortable positioning devices, poking and prodding. With laser dentistry the area around the tooth being worked on is virtually untouched, unlike in traditional dentistry. By isolating the area to be worked on, a dentist equipped with a laser is also isolating the area that could feel pain later on. And this theory carries on to postoperative swelling and bleeding as well. Some types of laser dentistry don't require local anesthesia.
Some Common Laser Dental Treatment
Root Canal Therapy: Laser root canal therapy uses a parallel beam of intense light to clean out root canals. Laser therapy "melts" away debris consisting of bacteria and infection, known as the "smear layer" of the root, and cleans the root more thoroughly than traditional treatments. With less time and pain than a conventional root canal, laser dentistry can remove your infection so that you can get on with your life.
Peridontal Gum Treatment or Pyorrhea: The laser seeks out and destroys the bacteria that are causing the disease. Using the laser technology the bad infection tissues are removed with greater accuracy, ease and almost painlessly. This removal allows access and vision to the roots that are infected for thorough cleaning of tartar or calculus and the removal of the infected cementum.
Fillings or Cavity Removal: Lasers are used to prepare dental cavities to receive fillings very well. Laser seeks out and destroys almost all bacteria in the cavity and leaves a pristine surface for bonding, unlike a drill which leaves contaminated smear layers on the surface.
By gum re-contouring: In “altered passive eruption”, the teeth have a square look to them, and at the height of your smile too much gum is displayed. By placing a little topical gel and using laser, the gums can be expertly defined to allow your teeth to reach their potential.
By moving teeth: The least invasive way to improve crooked looking teeth is to have orthodontics, and physically push the teeth into a beautiful position.
Reshaping teeth: Veneering or crowning of teeth using all ceramic systems
Caries Removal:Carious material contains a higher water content compared with surrounding healthy dental hard tissues. Consequently, the ablation efficiency of caries is greater than for healthy tissues. There is a possible selectivity in the removal of carious material using the laser because of the different energy requirement to ablate carious and sound tissues leaving those healthy tissues minimally affected.
Bleaching:The objective of laser bleaching is to achieve an effective power bleaching process using the most efficient energy source, while avoiding any adverse effects.
Advantages of Laser Dental Treatment
The rapid recent growth in the utilization of lasers is the result of dentist’s awareness and acceptance of an overwhelming number of laser benefits to the patient, the dentist and the practice.
With laser’s ability to coagulate as it cuts, there is little or no bleeding post surgery. Many laser procedures result in less post operative discomfort for the patient.
Preservation of healthy tooth structure: In general, cavity preparations performed with lasers preserve tooth structure while avoiding the micro-cracking of healthy enamel associated with dental handpiece use.
Laser Dentistry is a revolutionary step in dental care, which allows for the virtually pain free application of dental procedures with reduced swelling, trauma and bleeding. Crucially, the need for invasive implements and tools including the drill are eliminated.
Laser dentistry has proven quite successful in a vast array of soft-tissue cosmetic dentistry treatments, including gingival recontouring, frenectomies, and crown lengthening. Compared to more conventional approaches, laser dentistry provides a pain free treatment option and allows for a speedy recovery.
With laser technology, the dentist is armed with more and better treatment options than without a laser, resulting in delivery of the best, state of the art care possible for the patient.
The demand for lasers in dentistry is growing rapidly. Lasers provide absolute versatility in substitution of drills or blades, with more accuracy and precision, and comfort to the patient.
Risks Associated with Laser Dentistry
Like most surgical instruments, improper use of a laser can create problems; however, today’s lasers have many built-in safeguards to help prevent accidental damage. There are several key rules that must always be followed no matter what: eye protection should always be worn when a laser is in use, a dentist should always have proper training before ever working on a patient, and the laser should only be used for what it is intended for. When we consider the potential damage that may be caused by the improper use of the dental drill or scalpel, the laser is a very safe tool to use in the dental practice.
