Antimicribial Photodynamic Therapy Using Diode Laser on Candida Albicans

This study aimed to explore whether photodynamic therapy using Radachlorin and diode laser is an effective inhibitor of Candida albicans. Suspensions of Candida albicans were obtained, inoculated in petri dishes with Radachlorin, and incubated for 30 min. Then, the laser light of a diode laser was irradiated at at energy densities of 3 J/cm2 , 5 J/cm2 , 7 J/cm2 . As a result, Candida albicans showed a killing rate of 91.5% at an energy density of 7 J/cm2 . This study found that photodynamic therapy using a Radachlorin and diode laser was effective for the inhibition of Candida albicans.
