Aim: To compare SEKUDRILL with commonly used disinfectant KORSOLEX with respect to efficacy & the role of pH for ineffectiveness dental burs by evaluating microbial development in culture media.

Materials and methods: The following two disinfectants were used: Korsolex (Bohrerbad), sekudrill (Ecolab). There were four main groups taken as per the
Group 1: 15 drills sterilized by Autoclave
Group 2: 15 drills disinfected by Korsolex
Group 3: 15 drills disinfected by Sekudrill
Group 4: 15 drills served as control in saline
An aggregate of 60 tests, 15 sample for each disinfectant, have been obtained. One function as a control category, which implies that just a microbial count has been calculated without disinfection. Microbial measurement was conducted using a brain heart infusion (BHI) broth and included by plating in the blood agar and MacConkey agar.

Result: The analysis found that the endodontic burs sterilized by autoclave and preserved in sterile pouches at 121 ° C for 15 minutes at a pressure of 15 pounds (Group A) demonstrated absolute sterility. The drills subjected to korsolex chemical sterilization (Group B) showed more turbidity in culture media than sekudrill (Group C). The control group (Group D), which was not sterilized by either procedure, demonstrated turbidity in all the test tubes.

Conclusion: In present study, evaluation of bacterial growth and debris on surface is carried out. The result concluded that sekudrill is better disinfectant than korsolex. The burs which were autoclaved are the most sterile while most of the bacterial growth is encountered in control group.

Key words: Disinfection, Sekudrill, Korsolex, Turbidity
