Abstract
Conservation of deciduous teeth with pulp alterations caused by caries and trauma is a major therapeutic challenge in pediatric dentistry as a result of the internal anatomy and life cycle characteristic. It is essential that the root canal procedures sanitizers have a performance in eliminating bacterial. In this context, antimicrobial photodynamic therapy (PAT) is promising and emerging as adjuvant therapy in an attempt to eliminate the microorganisms persistent to chemi-mechanical preparation. Since there is presence of oxygen in cells, photosensitizer activated by light can react with molecules in its vicinity by electrons' or hydrogen's transfer, leading to microorganism death. This paper reports the case of 4-year-old patient, female, with early childhood caries. The proposed endodontic treatment incuded chemomechanical treatment allied to PAT in the decontamination of root canals using methylene blue dye 50 μg/mL during 3–5 minutes and 40 J/cm2 as energy density, taking into account the need for tissue penetration and effectiveness of PAT inside the dentinal tubules.
Highlights
Photodynamic therapy (PDT) involves the use of a photosensitizer that is activated by exposure to light of a specific wavelength in the presence of oxygen
Advances in tooth decay prevention have been translated into a reduction in its incidence and prevalence, and despite the efforts in this direction and understanding of the importance of maintaining the deciduous dentition healthy, often there are a high number of deep carious lesions in children where the disease is polarized, with pulp involvement
The maintenance of primary teeth with pulp changes caused by caries or trauma is a major therapeutic challenge in pediatric dentistry because of the pulpal biological cycle characteristic of these teeth as well as internal anatomy, the need for sanitizers root canal procedures that have a high performance in eliminating bacterial, since this leads to the success
