Effect of Photo Activated Disinfection on Osseointegration of Immediate Implants Placed in Infected Sockets

Traditionally, before placing dental implants, the compromised teeth are removed and the extraction sockets are left to heal from several months up to 1 year. Photodynamic therapy or light-activated disinfection is a technology based on the production of free oxygen radicals capable of affecting the membranes of microorganisms.The technique is composed of a photosensitizer substance usually toluidine blue that can be activated by light with susceptible wavelength. The photosensitizer after its activation produces energy capable of transforming the surrounding oxygen into free radicals, the free radical then attacks the exposed microorganisms.
