The high-temperature dental sterilizer (autoclave) is a core infection-control device for dental clinics, using pressurized saturated steam at 121–134°C to eliminate bacteria, viruses, fungi, and heat-resistant spores. It achieves a sterility assurance level (SAL) of 10⁻⁶, meeting global medical standards.

Most modern models are Class B pre-vacuum types: they first evacuate air from the chamber to ensure steam penetrates hollow tools (e.g., handpieces) and wrapped instruments. Standard cycles run at 121°C for 30–60 minutes or 134°C for 15–20 minutes, followed by vacuum drying to prevent recontamination.

Built with 304 stainless steel chambers, they feature microprocessor controls, touchscreen interfaces, and safety interlocks. Compact tabletop designs fit clinic workflows, with cycles as fast as 20 minutes for high-efficiency instrument turnover. Essential for safe dental practice, it prevents cross-infection .
