In a recent study, researchers have developed computer simulations showing how laser treatment kills oral bacterial colonies. This leads to the conclusion that benefits of using laser treatment in oral debridement include killing bacteria and promoting better dental health.
In a study published in the journal Lasers in Surgery and Medicine, the researchers show that the results of simulations representing different laser wavelengths pointed at virtual bacterial colonies buried in gum tissue.
In humans, actual bacterial colonies can cause gingivitis or gum problem such as inflammation. Gingivitis is a common and mild form of gum disease that causes irritation, redness and swelling (inflammation) of your gums. It can develop into periodontal disease, which involves a more serious infection that breaks down the bones and tissues that support the teeth.
"The paper verifies or validates the use of lasers to kill bacteria and contribute to better health following periodontal treatments," said co-author Lou Reinisch, Ph.D., associate provost for academic affairs at New York Institute of Technology.
Researchers produced simulations of 3 different types of lasers commonly used in dentistry to answer this question. They also show the effects of the two types of bacterial colonies of various sizes and depths within the gum models.
The simulations indicated that when to short pulses and moderate energy levels, the 810 nm diode lasers could kill bacteria buried up to 3mm deep in the soft tissue of the gums. On the other hand, the 1064 nmNd, called YAG laser was also effective with similar depth.
Both of the lasers saved the healthy tissue and minimize the thermal damage that led to faster healing. The cost of dental laser treatment can range from $5,000 to more than $100,000. Aside from this amount, dentists or other health care professionals may require extra training to use them.
These costs are passed on to the patient, so there must be a definite benefit for the patient to justify the price. In conclusion, the result gained by the researchers verifies that the laser treatment can really kill bacteria to better tooth health.
