Antimicrobial photodynamic therapy as a complement in the direct restorative treatment
Keywords:
Photodynamic therapy, low power laser, dental cariesAbstract
Dental caries is a multifactorial disease that affects a large majority of the population, which presents microorganisms within its development process. However, the main objective in this case report is to reduce the level of microorganisms presents in tissues affected by caries disease, either enamel or dentin to achieve a successful restoration. In this restorative process of dental caries, the use of low-power laser along with a chromophore element, which penetrates the microorganisms, creating a reaction that will destroy the microorganism present in the carious process, this process will be called Photodynamic Therapy (PDT). Antimicrobial Photodynamic Therapy (aPDT) is a technique that combines the activation of a photosensitizer by light in the presence of oxygen producing reactivation of radicals that induced the cell death of the microorganisms. This aPDT has been used to reduce the amount of microorganisms being an antimicrobial potential in the caries process in a direct restorative process, thus avoiding the process of recurrent caries in which it happens when there is no exhaustive previous process of the elimination of the remains of microorganism after clean the cavity with rotating instruments. In the following clinical case report we will present a patient with a caries process in which we introduced the aPDT in the restorative process of tooth 3.5, as an alternative, for an optimal reduction and elimination of microorganisms that involve in the carious process and thus improving the quality of our restoration with resin, and extending the life of this restoration.
