Oven-type sterilizer (dry heat) settings are typically which combination?

Dry heat sterilization relies on hot, dry air to kill microorganisms, and because there’s no moisture to assist heat transfer, you need a longer exposure to ensure all surfaces reach sterilization. In dental practice, the typical oven-type, dry heat cycle is about 320°F for 60 to 120 minutes. This combination provides reliable sterilization of instruments while avoiding excessive heat that could damage tools or wrappers. The other options use either too low a temperature or too short a time (or both), which would not reliably achieve sterilization with dry heat.
