Abstract :

Aim– this study was done to evaluate the efficacy of five different procedures on elimination of biological deis on rotary endodontic instruments before sterilization.

Materials and Method– totally twenty–five rotary endodontic files after clinical use for cleaning and shaping were taken in the study. They were divided into five groups each containing five files in accordance with various cleaning procedures used. Detection of deis on files was done using rhodamine B stain with the help of stereomicroscope.

Statistical analysis used:results were analyzed using Kruskal–Wallis Chi– Square test.

Results:the mean value of maximum biological contamination was highest in Group 2(files immersed in 2% glutaraldehyde solution) and lowest in group 5(files which were cleaned using ush).

Conclusions: endodontic instrument which were cleaned manually using nylon ush were found to be more efficient.
