Introduction: Chemo-mechanical irrigation for cleaning the infected root canals does not ensure complete removal of microorganisms. Objectives: The aim of this study was to estimate efficacy of Er:YAG laser compared to conventional methods for the treatment of infected root canals. Methods: The study included 400 freshly extracted premolar single-rooted teeth. Crowns were cut off obtaining 15 mm long samples of the root canal. The apical part was drilled through. Teeth were divided into four groups inoculated with different microbial strains (Enterococcus faecalis, Streptococcus sanguinis, Fusobacterium nucleatum and Candida albicans). Three different methods for removal of microorganisms were applied, i.e.: Er:YAG laser radiation, irrigation with 5.20% NaOCl and Qmix. Microbial viability was analyzed by flow cytometry. Results: All treatment methods effectively eliminated the majority of microbial cells. Statistically significant differences were observed in mean percentage of dead cells between tested organisms (p |
