Device | The Dentronix DDS 7000 Rapid Dry Heat Sterilizer Sterilization System is substantially equivalent to
the Dentronix DDS 5000 Dry Heat Sterilization System, referred to as the "DDS 5000" for the
remainder of this document, legally marketed per 510(k) K880322. The DDS 7000 utilizes the same
accessories used by the predicate device. | | General
Description | The DDS 7000, like the DDS 5000 is a convective dry heat batch sterilizer capable of sterilizing un-
bagged dental instruments and cooling them for immediate use. It is designed for use with a dedicated
rack system that provides for uniform loading to achieve optimum load distribution.
The DDS 7000 is equipped with a replaceable HEPA filter to comply with ANSI/AAMI ST50: 2004
cooling requirements. The HEPA filter has a filtration efficiency of 99.7% for 0.3-micron particles.
The DDS 7000 is a software-controlled device that allows for the user to preprogram options such as
display units (Celsius or Fahrenheit), audible alarm enabled/disabled and safety interlock
enabled/disabled The DDS 7000 monitors the entire cycle and will provide diagnostic error codes in
the event of any failure or disruption to the sterilization cycle. A printable log is available for the most
recently performed cycle that includes pass/fail notification and error codes if applicable | | Intended Use | The DDS 7000 is a countertop convective dry heat sterilizer designed for use in Healthcare
facilities for the sterilization of un-bagged dental instruments that can withstand exposure
temperatures up to 216°C (420° F). There is a single software-controlled cycle that includes
a warm-up and cool down phase in addition to the 3-minute sterilization (exposure) phase.
Sterilize (exposure) starts when the RTD/control temperature reaches the operating
temperature set point of 190°C (374° F). Complete cycle times average 34-44 minutes and
are load dependent. The DDS 7000 achieves optimum results by uniform load distribution
utilizing a dedicated rack and tray system as detailed below. | | | 1) Maximum recommended loads for the DDS 7000-115 sterilizer: | | | a) Maximum load for a four (4)-rack configuration is four (4) plier racks each holding

system | | | | Performance
Testing | Temperature studies were performed on full, partial and empty chambers. Performance testing of the
DDS 7000 was performed using Bacillus atrophaeus spore strips and inoculated tools using the same
organism. Half cycle kills result in an overall 12-log reduction of spores and thus produces a 106
sterility assurance level (SAL). This testing showed that the DDS 7000 is as safe and effective and
performs as well if not better than the predicate device (DDS 5000). | | | | Software
Validation | The software was designed and validated to assure that the device is as safe and effective or better than
the predicate device (DDS 5000). "General Principles of Software Validation; Final Guidance for
Industry" and "FDA Staff and Guidance for the Content of Premarket Submissions for Software
Contained in Medical Devices; Final" were used in the development and validation of the device
software. | | | . : {5}------------------------------------------------ Image /page/5/Picture/0 description: The image is a simple black and white image with a few small, dark, irregular shapes scattered across a white background.
