Periodontitis and Laser Management

Periodontal inflammation around teeth and implants is associated with specific periodontal pathogens. The increasing number of infections, the negative impact on systemic diseases and evidence of complications during implant treatment, highlight the need for dentists to search for cause-and-effect relationships to identify efficacious treatment(s).

One of the main causes of periodontal complications is the interaction between specific bacterial biofilms and the associated host inflammatory response. To ensure long-term success and a highly predictable outcome of the treatments, dentists should be heedful of the first signs of inflammation and perform effective treatments. To achieve an effective treatment, periopathogens need to be eliminated. Usually, conventional treatments are complemented with additional antibacterial therapy with the use of antiseptics. However, research has so far proven the efficacy of laser therapy, as an adjunct to the conventional treatment. Laser technology, despite of the controversy, is becoming increasingly popular in every day dental practice because it provides predictable treatment outcomes and it is well accepted by patients. Laser treatment is used for the decontamination of periodontal tissue and the cementum on the root surfaces. It is a non-invasive medical treatment as it relies on the strong bactericidal and detoxifying properties of the laser. During the lecture we will consider the novelty of using laser therapy in combination with antiseptics as an alternative treatment protocol.
