Abstract :

Aim of the study To measure effect of magnetized water irrigation with the use of 5.25% sodium hypochlorite solutions on bacterial load on the dentine walls in prepared canals in vitro. Material and methods Sixty–four extracted teeth were evaluated and divided into two groups. In Group 1, after gaining access to the root canal, bacteria found on the canal walls was sampled using endodontic files. A further sample was taken after apex location and initial widening of the canal had been completed and magnetized water irrigation was done. At the end of the procedure a last bacterial sample was gained, In Group 2, the initial sample was taken as described previously. A second sample was taken after conventional preparation using 5.25% sodium hypochlorite solutions irrigant , and a third sample was taken as in group 1. All samples were cultured for facultative anaerobic bacteria. Results: In Group 1 only two of the 23 canals showed bacteria after the use of magnetized water irrigation and of these two canals, one was free of bacteria on completion of conventional treatment but the other still contained bacteria. In Group 2, four canals of the 23 infected initially, remained contaminated after conventional treatment. Conclusions: The results of the study indicate that the use of magnetized water as a cleaner and disrupter of the biofilm is an effective alternative to the use of hypochlorite as a root canal cleaning system
