A Bright Future for Lasers in Dentistry By Brian
J. Gray, DDS, MAGD, FICOI While the laser isn't any faster in cavity treatment than the traditional dental handpiece, it does offer several advantages. Good news for cavity treatment: lasers often eliminate the need for anesthetics! Additionally, they can speed up the preparation time, since dentists can begin the procedure without having to wait for an injected anesthetic to work. As a result, patients can leave the dental office without having their mouths numb! While lasers are showing promise for treatment of dental cavities, currently they are not being used for certain procedures, such as removing amalgam fillings or in crown preparation. Assuring Safety After reviewing the research and studies of lasers in cavity preparation for small-to-moderate sized cavities, the American Dental Association's Council on Scientific Affairs believes laser technology holds promise for restorative procedures in the near future. It has invited manufacturers to submit their laser systems for thorough evaluation under ADA's Seal of Acceptance program. This provides both dentists and consumers with assurances that advertising claims are true and product labeling is clear. In addition to cavity preparation, the FDA has approved the use of dental lasers for a number of procedures: gum surgery, teeth bleaching or whitening, canker sore treatment, and the treatment of gums that have become diseased. Lasers are currently being studied for other dental treatments such as decay prevention and root canal therapy. Clinical studies have shown that laser treatment can make teeth more resistant to the acids that can lead to tooth decay. Another type of laser has been effective in cleaning out root canals during therapy before the canal and the teeth are sealed. Lighting the Way for the Future Look for the light in the new millennium, bringing a new wave of exciting dental procedures. Patients can look forward to greater comfort and precision care provided by laser technology. |
