Abstract

  Periodontitis is the chronic inflammation of supporting structures of teeth and is the major reason for tooth loss. The objective of periodontal therapy is to reduce the bacterial burden. Non-surgical therapy is considered as the gold standard technique of periodontal therapy. Phototherapy using low level lasers is called photodynamic therapy. Photodynamic therapy targets the specific pathogen without damaging the host tissue. This is effective for killing drug resistant pathogens and in treating multidrug resistant infection. Photodynamic therapy has three different components i.e. light, photosensitizer and oxygen. There are two mechanisms in antimicrobial photodynamic therapy. One is DNA damage and the second method is damage to the bacterial cytoplasmic membrane resulting in inactivation of the membrane transport system, inhibition of plasma membrane enzyme activities, lipid peroxidation and others. In photodynamic therapy bacterial killing is mainly by damaging the cytoplasmic membrane of bacteria. It has different applications in various fields of dentistry. In periodontics it is used for treating both periodontitis and periimplantitis. The adjunctive use of PDT to scaling and root planning in the treatment of patients with chronic periodontitis, aggressive periodontitis and periimplantitis, resulted in greater clinical attachment level gains, reduction in bleeding on probing and probing pocket depths. The aim of this review is to describe briefly about the photodynamic therapy and its uses and evidences in periodontics and implant dentistry.
