Key Learning Points
- Critical instruments penetrate soft tissue or bone and must be sterile before use
- Semi-critical instruments contact mucosa and require sterilisation where possible
- Type N autoclaves are suitable for solid, unwrapped instruments only
- Sterilisation logs must record cycle parameters (time, temperature, pressure)
- Reusable instruments must go through cleaning, disinfection, and sterilisation
