Photodynamic therapy of Curcuma longa extract stimulated with blue light against Aggregatibacter actinomycetemcomitans

Aggregatibacter actinomycetemcomitans is a pathogenic bacteria associated with aggressive periodontitis and also responds poorly to conventional treatment [1]. Photodynamic therapy (PDT) is an alternative treatment that has shown to effectively reduce periodontally pathogenic bacteria [2 –4]. Photodynamic reaction is based on light stimulation of an appropriate photosensitizer (PS) to generate reactive oxygen species that are toxic to the target cells and tissues [5–7].
