Scientists proved denefits of laser treatments in dentistry
Researchers have developed computer simulations showing how lasers attack various bacteria in oral cavity. With this study, it is possible to carry out more effective debridement, killing bacteria and promoting better dental health.
Scientists have published the results of simulations depicting various laser wavelengths aimed at virtual bacterial colonies in periodontal tissue that can cause gingivitis, which also develops in periodontitis. This disease could lead to serious infection that breaks down the bones and tissues that support teeth.
Co-author Lou Reinisch, Ph.D., associate provost for academic affairs at New York Institute of Technology said that the experiment confirms the effectiveness of laser in dentistry, because with its use you would not only kill bacteria but also contribute to better health following periodontal treatments.
Dr. Reinisch is specialized in physics and optics. Being an expert in the field of laser surgery, he recreated a mathematical model based on the optical characteristics of the gum tissue and bacteria. Then, he conducted simulations of three different types of dental lasers and their effects on two types of bacterial colonies, placed within different depths of periodontal tissues model.
Co-author David Harris, Ph.D., director of Bio-Medical Consultants, Inc., said that this research demonstrates what's going on between lasers with the gums tissues. He also added that it is necessary to teach medical personnel that you can do a good job of killing bacteria with certain lasers. Therefore, with this treatment, dentists remove an infection and allow tissue to regenerate.
Laser light interacts with tissue has implications not only in dentistry but also in physicians and treatments, including vocal cord procedures and dermatological treatments.
