Light‐emitting‐diode‐based antimicrobial photodynamic therapies in the treatment of periodontitis.

The use of light‐emitting diode (LED)‐based photodynamic therapies in the treatment of periodontitis is increasing because these modalities are effective, safe, and painless. They are not subject to acquired drug resistance or environmental issues and are associated with no complications when used appropriately. These light sources have also been used in combination with pharmacological measures to synergize their effects and optimize therapeutic outcomes. This review focuses on optical devices used in treating periodontitis and delineates the current applications of various methods, including their utility and efficacy. The application of LEDs in periodontology is described. [ABSTRACT FROM AUTHOR]
