Abstract
Periodontal disease results from inflammation of the supporting structure of the teeth and in
response to chronic infection caused by various periodontopathic bacteria. The mechanical
removal of this biofilm and adjunctive use of antibacterial disinfectants and antibiotics have
been the conventional methods of periodontal therapy. However, the removal of plaque and the
reduction in the number of infectious organisms can be impaired in sites with difficult access.
Photodynamic therapy (PDT) is a powerful laser‑initiated photochemical reaction, involving
the use of a photoactive dye (photosensitizer) activated by light of a specific wavelength in the
presence of oxygen. Application of PDT in periodontics such as pocket debridement, gingivitis,
and aggressive periodontitis continue to evolve into a mature clinical treatment modality and is
considered as a promising novel approach for eradicating pathogenic bacteria in periodontitis.
