PHOTODYNAMIC THERAPY
AN OPTION IN PERIODONTAL THERAPY
Keywords:
Periodontal disease, Laser, Photodynamic therapyAbstract
The main goal of the periodontal treatment is the re-establishment of the periodontal health. The success of periodontal therapy depends on the adequate elimination of the etiological factors, such as dental plaque and calculus deposited on the root surface. However, mechanical therapy may not be sufficient for the total elimination of bacterial plaque. Some areas such as furcations and root depressions are inaccessible to adequate periodontal instrumentation. Thus, some periodontal pathogenic bacteria can invade the soft tissues and dentin. Therefore, there is a continuous search for adjunctive methods to improve the results obtained by mechanical therapy. The purpose of this paper is to present a review of the literature focusing on studies that have evaluated the effect of photodynamic therapy (PDT) on periodontal pathogens. The studies have demonstrated that PDT is effective in reducing the amount of bacteria, including periodontal pathogens; and, thus, proves to be an adjunctive method for non-surgical periodontal treatment. New studies should be conducted in order to determine the specific parameters of the lasers and drugs to make the PDT more effective and predictable.
