Laser dentistry

Since 1960, when it was created the first laser device for medical use, research tended to look for a tool capable of improving traditional techniques and replace the rotary instruments used in dental (around or turbine).

It was not until 1997, the United States Food and Drug Administration (FDA) approved the use of laser Erbio on hard tissues (tooth). That approval was achieved by the signing Premier Laser Systems (USA) for his team called "Centauri." Until then, the entire laser's use, proved to be very useful for application in oral soft tissue remains such as gums and mucous membranes, hence it's more widely in the field of surgery and dentistry.

Today we know that the applications have expanded laser uses included on dental bleaching, Surgery, cavities and chronic pain treatments, and so on.

LASER at an English acronym of the words "Light Amplification by Stimulated Emission of Radiation", in other words, a highly energetic beam of light, with specific properties and the ability to interact with tissue irradiated getting a therapeutic effect.

In the case of dental caries, the light beam impinges on the tooth and removes the diseased area exclusively on the surface and pulsed, being absolutely safe to use.

Moreover, being selective in its action promptly, because it gets into those extremely small cavities with no need for large amounts of wear down tooth healthy. These wells will be restored with Halogen Light and aesthetic materials.

The action of the laser on the tooth superficially gives the patients as profit almost unnecessary application of anesthesia, no attendant risks, needles, and unpleasant numbness at the end of the consultation. The patient usually can continue with their normal duties.


       Efficiency: Its use saves time, eliminates some steps, combines and simplifies others, and introduces new and elegant solutions to old problems such as hypersensitivity.

       Accuracy: It allows precise control to the dentist, making possible interceptive treatments of the disease and helping to prevent the destruction of healthy tissue.

       Field dry: The virtual absence of bleeding during procedures with laser reduces the risk of infection to both patient and dentist, and allows the dentist can better observe the site of operation.

       Lack of pain: There is no pain; although occasionally may be required anesthesia. This offers a new opportunity to those patients to avoid that fear for pain, and finally removes the association between dentistry and pain.


    A survey of patients treated with the laser indicates that the 100% preferred this method including the preferences from their families and friends. While, 75% did not return to a dentist who does not use laser and were willing to pay more for dental laser if necessary.

    The light therapy has invaded our treatment, incorporating not only technology but agility and welfare in the post-operative patient such as those with epitelización and healing of connective tissue. Therefore the use of this new technique is applicable in both soft and hard tissues by different types of laserat various tissues of the oral cavity.

    There are many types of láser, being the HN and CO2 the most usable, such as hervio yag, neodinium yag, diiodo, excimer, and so on. Comparatively evaluated, both HN and CO2 are two devices for different uses, with several technical, physical and therapeutic characteristics.

       HN: Helium Neon
      It is for soft tissues, low energy. Its properties are: visible light, low energy, healing, analgesic, bioestimulante.
       CO2: Carbon dioxide
      It is for soft tissue, such as surgical excisions frenectomía and hard tissues, removal of decay. Its properties are: non-visible light, high-energy, incisions in mucous membranes, sterilization of hard tissues.
In conclusion, we can say that the dentistry of the twenty-first century, is nothing less than the elimination of around for the treatment of tooth decay, no noise, no vibration, no pain, no anesthesia, no punctures and aesthetic restorations, and more durable.
