Summary
Dental practices widely use steam sterilisers for reusable instruments, but significant issues exist in their installation, testing, and operation. Improved training and technical support are crucial for ensuring instrument safety and effective decontamination.
Area of Science:
- Infection Control
- Medical Device Sterilization
- Dental Public Health
Background:
- Reusable instrument sterilization is critical in general dental practice to prevent cross-contamination.
- Benchtop steam sterilisers are commonly used, necessitating proper installation, commissioning, and ongoing testing.
Purpose of the Study:
- To evaluate the sterilization methods for reusable dental instruments in general practice.
- To assess the installation, commissioning, and testing procedures for benchtop steam sterilisers.
Main Methods:
- An observational study involving direct viewing of policies and procedures by trained surveyors.
- Interviews and record reviews were conducted regarding steriliser installation, commissioning, and testing.
Main Results:
- 88% of practices use Type N (bowl and instrument) sterilisers; only 51% were tested on installation and 26% commissioned.
- Significant deficiencies were noted in operational instructions, record-keeping, segregation of clean/dirty areas, traceability, and staff training.
Conclusions:
- Despite widespread adoption of steam sterilization, critical shortcomings in equipment management and user training potentially compromise patient safety.
- Enhanced education, training, and technical support are needed for dental professionals and equipment suppliers to improve sterilization practices.

01:30Methods of Sterilization II: Chemical Methods
In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
Using chemical sterilization rather than heat to clean out equipment is recommended. It eradicates and removes all bacteria,...

01:29Methods of Sterilization I: Physical Methods
As used in a healthcare facility, sterilization destroys all microorganisms through physical or chemical methods. The physical method includes steam, dry heat, boiling water, and radiation.
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...

01:30Cleaning, Sterilization, and Disinfection
Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

01:26Physical Methods for Controlling Microbial Growth: Radiation and Filtration
Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.
01:19Key Techniques in Microbiology
Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...
01:23Hand hygiene
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.
