Effects of Photodynamic Therapy in Root Canals

Endodontics is a specialty of dentistry that aims to preserve teeth in the oral cavity so that they can continue to function even without vitality. Microorganisms and their metabolic products are considered the main causes of pulp and periapical diseases. For endodontic treatment to be successful it is important to reduce or eliminate microorganisms which is achieved through instruments and chemical aids. In this perspective photodynamic therapy has been used as a complementary treatment that uses low-power laser associated with a photosensitiser to promote the death of microorganisms in the root canal system. Thus this book seeks to describe how photodynamic therapy works in root canals contaminated by Candida Albicans helping clinical dentists and specialists to combat dental infections in order to achieve successful treatment outcomes.
