Dekiler-Box Sterility Test as an Innovation in Multifunction Sterilization Equipment for Dental Instruments

Abstract

Abstract. Sterilization is the process of destroying or eliminating all microorganisms. The aim of sterilization is to destroy every form of pathogenic microorganism including spores that might adhere to dental instruments and associated equipment. Dental instruments that come in direct contact with the human body have a very high risk of transmitting diseases caused by microorganisms; therefore, it is important to keep the instruments sterilized. The Dekiler Box is an innovation in sterilization equipment to help dentists in rural areas. This piece of equipment has several advantages, including practicality, multifunctions, portability, and zero use of electricity. The aim of this study was to determine the sterilization effectiveness of the Dekiler Box through differences in the quantities of bacteria on dental instruments compared to an autoclave. This was an experimental study that compared dental instruments before use, after use, and after being sterilized with the Dekiler-Box sterilization equipment. The results showed that bacteria increased significantly after instrument use and decreased after sterilization with the Dekiler Box. In conclusion, sterilization of dental instruments using the Dekiler Box was effective for reducing bacteria on dental instruments.

Sterility and bioactivity evaluation of two types of bone graft substitutes after removing the original packaging

“…13,14 A sterility test is one of the examinations needed to assess any contamination in sterilized bone grafts. 15 Moreover, scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX) are two other possible tests for the physicochemical and bioactivity evaluation of biomaterials. SEM imaging technique provides information regarding the morphology of granules, while EDX analysis shares information on the chemical elements present in the biomaterials and surrounding tissues, qualitatively and quantitatively.…”
