The main purpose of sterilization in dental practice is to eliminate all living microorganisms. In a dental setting, instruments come into contact with blood, saliva, and other potentially infectious materials. Therefore, it is critical to achieve a level of cleanliness that not only reduces the number of bacteria but completely eradicates all forms of microorganisms, including viruses, bacteria, fungi, and spores.

Sterilization is necessary to prevent the transmission of infections between patients, ensuring a safe treatment environment. Simply cleaning instruments or preparing them for storage does not remove the risk of infection. While ensuring instruments are clean is part of the overall infection control process, it does not guarantee the complete elimination of all microorganisms, which is the distinctive goal of sterilization. Hence, sterilization plays a vital role in maintaining high standards of patient care and safety in dental practices.
