# Substantial Equivalence Discussion
The proposed BDC and predicate device are similar in all the items in the comparison chart except water pressure, patient load, chair height, back/head rest, lift motor, foot control and models. These differences do not affect substantial equivalence, also the subject device safety was verified with testing according to IEC 80601-2-60 and IEC 60601-1.
As the models/types do not differ significantly in purpose, design, materials, energy source, function or any other feature related to substantial equivalence.
On the basis of the discussion above, it is concluded that the subject device is substantially equivalent to the predicate device.
{8}------------------------------------------------
# VII. Non-Clinical Test Data
The following performance data were provided in support of the substantial equivalence determination.
#### Biocompatibility testing
The biocompatibility evaluation for the 3-way syringe , high-volume suction, saliva ejector, and tubing were conducted with the following performance standards:
ISO 10993-5: 2009 Biological evaluation of medical devices — Part 5: Tests for in vitro cvtotoxicity ISO 10993- 10: 2010 Biological evaluation of medical devices — Part 10: Tests for irritation and skin sensitization
The 3-way syringe, high-volume suction, saliva ejector, and tubing of testing included the following tests:
- Cytotoxicity
- Sensitization
- Irritation
The tubing and syringes body are considered as indirect tissue contacting.
Such like armrest pad, dental operating light handles, upholstery seat, 3-way syringe, high volume evacuator and saliva ejector, we recommended using a barrier sleeves and barrier film which is non-sterile and intended for single patient use only.
## Reprocessing Validation
Reprocessing validation was conducted per FDA Guidance, "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling - Guidance for Industry and Food and Drug Administration Staff (fda.gov)" including cleaning, disinfection, and sterilization validation for the components of the BDC Dental Unit.
As to the body/head of the 3-way syringe, high-volume evacuator, and saliva ejector, even though we conducted the Cleaning, intermediate disinfection testing on them, due to their connection which is fixed, the user can not disassembly them from the tubing, so we recommended in our IFU not only the cleaning and disinfection method, but also we recommend to wear compatible FDA-cleared disposable barriers when using them. Cleaning and Sterilization validation was conducted for the 3-way syringe tip.
In addition, cleaning and disinfection validation was provided for the surfaces of the subject device. Cleaning and disinfection vas conducted on the waterlines and water bottles of the subject device. Validation was conducted using the standard 16954:2015 Dentistry - Test methods for dental unit waterline biofilm treatment.
## Electrical safety and electromagnetic compatibility (EMC)
The Electrical Safety and Electromagnetic compatibility tests were performed in accordance with the following standards. Comprehensive performance testing has been conducted on the BDC dental unit in accordance FDA recognized standards. EMC testing was conducted in accordance with Standard EN/IEC 60601- 1-2. Electrical, and environmental safety testing according to Standard EN/IEC 60601- 1 was performed and IEC 80601-2-60 Particular requirements for the basic safety and essential performance of dental equipment.
{9}------------------------------------------------
#### Software Verification and Validation Testing
Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Content of Premarket Submissions for Device Software Functions." The software for this device was considered as a "BASIC" level of concern, since a failure or latent flaw in the software would not directly result in serious injury or death to the patient or operator.
#### Performance Test
The performance tests were conducted as bench test and the test results met the pre-set criteria.
- ISO 7494-1 Third edition 2018-06 - Dentistry - Dental units - Part 1: General requirements and test methods
- ISO 7494-2 Second edition 2015-01 - Dental units - Part 2: Water and air supply - ISO 9168 - 2009-07- 15 - Dentistry - Hose connectors for air driven dental handpieces devices
## Clinical Testing
Clinical data is not needed to characterize performance and establish substantial equivalence. The non-clinical test data characterize all performance aspects of the device based on well-established scientific and engineering principles. Clinical testing has not been conducted on this product.
#### VIII. CONCLUSIONS
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, the BDC dental unit is substantially equivalent to K3, the predicate device, in intended Use/indications for use, material composition, fundamental engineering technology, the principle of operation and basic design.
