Abstract: Objective

To obtain the optimal temperature, the operating life after the configuration of the detergents, and the best reuse times of the detergents corresponding to the two kinds of multi-enzyme detergents, which were commonly used in the cleaning and disinfection of dental instruments.

Methods

In this study, the multi-enzyme detergents currently in commercial use were taken as the research objects, according to the best working temperature, configuration time and frequency of fluid change, explore the optimal conditions for the use of multi-enzyme cleaning agents.

Results

The optimal temperature of group one treatment is around 55 ℃, while the optimal temperature of group two is around 50 ℃. Too long detergent configuration time or repeated use of multiple enzyme detergent in batches may result in reduced disinfection effect. Reasonable control of the number of instruments, use within an effective time period, and timely replacement of multi-enzyme detergents are important methods to ensure the disinfection effect.

Conclusion

Controlling the working temperature at about 50-55 ℃, using the multi-enzyme detergents of the configuration time, and the cleaning times of not more than three times can help to clean the dental instruments efficiently.

Key words: multi-enzyme detergent, oral instrument, hospital infection control
