Comparative evaluation of the effectiveness of light activation of photosensitizers in photodynamic therapy of periodontitis using different wavelengths

Abstract

Dentists are always in quest of new methods for the treatment of periodontal diseases, and photodynamic therapy (PDT) is considered one of the most effective methods. A significant improvement in the clinical pic-ture was obtained in all patients throughout the control period of observation of the patients as a result of the treatment with the use of PDT. According to the data from research study it can be said that photodynamic therapy is an effective and gentle method of antibacterial treatment of inflammatory periodontal diseases, which can be effectively used to prevent exacerbations of chronic inflammatory periodontal diseases, to achieve a long-term positive effect and to refuse, in some cases, from surgical methods of treatment. There is a signifi-cant increase in the duration of remission of the disease, improvement of microcirculatory blood circulation in per-iodontal tissues and a small microbial contamination of periodontal pockets of patients treated with photodynam-ic therapy in the long term compared with groups of patients treated with only antiseptic and antibacterial drugs.
