Laser technology in endodontic treatment of chronic apical periodontitis: comparative evaluation of antibacterial efficiency

Abstract

In a modern endodontics the disinfection of infected root canals still remains a challenging problem, because mechanical removal of organic remnants and microorganisms from lateral canals and ramifications of the apical delta is impossible. In the present report the efficiency of using diode laser and photo-activated therapy (FAT) during endodontic treatment of the infected root canals was estimated. Analysis of clinical and radiological results revealed higher efficiency of diode laser (97,7%) and photo-activated therapy (100%) in endodontic treatment of chronic apical periodontitis compared with the conventional root canal treatment (92,7 %). It is proved that the use of laser radiation and photo-activated therapy in treatment of chronic apical periodontitis allows to reduce number of complications and to accelerate bone healing in comparison with a traditional method of treatment with calcium hydroxide preparations.
