Abstract

Periodontal disease is a family of chronic inflammatory conditions caused by bacterial infections.' It is manifested in red, swollen gingiva (gums) and can lead to destruction of the connective tissue and bone that hold teeth in place. Conventional treatments typically require some form of invasive surgery, depending on the disease stage at time of detection. Photodynamic Therapy (PDT) is the use of light-activated drugs (photosensitizers) for treatment of a variety of conditions 2 such as solid tumors, pre-malignancies, macular degeneration and actinic keratitis. There have been a number of studies of PDT as an antibacterial agent. 3'4 Depending on the photosensitizer and strain of bacteria, significant killing (several LOGS) can be achieved.
