Intended Use

RX DC x-ray unit is designed for use in the dental surgery to make endo-oral x-rays for diagnostic purposes. This equipment can be used to produce traditional x-rays developed using chemicals or, alternatively, it can be used with digital x-ray sensors.

Device Story

RX DC is an extraoral dental X-ray system for intraoral imaging. System comprises a mobile/articulate support arm, control unit, and tube head with X-ray tube. High-frequency, constant-potential generator produces X-rays at 65/70 kV and 8 mA. Device automatically calculates exposure time (0.02s–1.00s) based on selected tooth type and patient size. Used in dental clinics by dental professionals. Output is X-ray radiation for capture on conventional film or digital sensors. Healthcare providers use images for diagnostic assessment of teeth and oral structures. Benefits include optimized exposure parameters for diagnostic quality imaging.

Clinical Evidence

Bench testing only. Safety and EMC testing conducted per IEC 60601-1, 60601-1-6, 62366, 60601-1-3, 60601-2-65, and 60601-1-2. Comparative dosimetric testing measured air kerma across loading factor combinations (patient size/tooth anatomy) against predicate K080076, confirming equivalent X-ray emission performance.

Technological Characteristics

High-frequency, constant-potential X-ray generator; tungsten anode; 65/70 kV tube voltage; 0.4mm/0.7mm focal spot. Articulated support arm (40-90cm). Wired/wireless control. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3, IEC 62304. Microprocessor-controlled exposure.

Indications for Use

Indicated for dental surgery patients requiring endo-oral x-ray imaging for diagnostic purposes.

Regulatory Classification

Identification

The RX DC, in the new 65/70 kV version, is substantially equivalent to the following device:

#### 4. Device Description

The subject device RX DC, in the new 65/70 kV version, is an extraoral source dental X-ray system intended for intraoral imaging. The subject device is a device comprises a double mobile and articulate support arm. At the opposite ends of the arm are located, respectively:

- . A control unit equipped with wall plate, extension arm and wired/wireless control device;
- A tube head with x-ray tube; .

X-rays are produced using the high frequency and constant potential generators with a built in round collimator with the high frequency (HF) technology, X-ray emission at 70 kV and 8 mA (maximum power), and x-ray unit automatically calculates the best exposure time (from 0.02 s to 1.00 s) based on the selected tooth and patient size, as well as an adjustable arm allows for easy positioning. The system can be used either with conventional film or a digital imaging system. RX DC, 65/70 kV version, is manufactured by CEFLA S.C. and available in several versions, and it can be sold under different brands and commercial names for commercial needs, as well as with different type of installation, and also different types of maximum anode voltage (65 kV or 70 kV). To identify the different variants of the RX DC product, CEFLA S.C. designed a reference system to identify any variant via the REF code.

## 5. Indications for Use

RX DC x-ray unit is designed for use in the dental surgery to make endo-oral x-rays for diagnostic purposes. This equipment can be used to produce traditional x-rays developed using chemicals or, alternatively, it can be used with digital x-ray sensors.

## 6. Comparison of technological characteristics with the predicate device

The RX DC, in the new 65/70 kV version, represents a development of the cleared RX DC (K080076), which has a fixed x-ray tube potential 60kV. In addition, concerning the maximum voltage of 70KV, this parameter is identical to that of the other predicate device K120318.

According to table above, the subject device has similar technology and features than the predicate devices K080076 and K120318, pointing out only few differences.

The differences like the highest energy available is 70 keV or the necessity to manage a wired controller together an others, together with some electronic changes introduced in the subject device, as indicated in the table, have caused the need for software changes in order to allow the firmware porting, but the two mains parts of the software, that consist of the user interface management and the control algorithms that manage the x-ray tube remained substantially the same. Finally this modification has been validated in compliance with the same standard used in the predicate device as indicated in the comparison table

Furthermore all these differences have been addressed by dedicated performance tests demonstrating that the technical differences have the equivalent results concerning the performance of the dose released during the radiographic exposition. Therefore, the subject device is able to produce comparable performances in term of emitted dose respect the correspondent dose emitted by RX DC cleared by FDA with K080076.

{7}------------------------------------------------

### 7. Performance Data

The following tests were performed for determination of substantial equivalence:

1) Non clinical tests performed on the subject device:

A. Safety and EMC tests conducted in compliance with the declared standards:

- IEC 60601-1:2005 ●
- IEC 60601-1-6:2013 ●
- IEC 62366: 2014 ●
- IEC 60601-1-3:2013 ●
- IEC 60601-2-65:2012
- IEC 60601-1-2:2007 (EMC) ●

For all consensus standards here above all requirements have been met.

### B. Comparative dosimetric test:

The test purpose is to measure the air kerma emitted by the subject device and RX DC (K080076), for each combination of loading factors accordingly to patient size and anatomical shape of the tooth, in order to verify that the technical differences have the equivalent results concerning the performance of the dose released during the radiographic exposition

The test results demonstrated that RX DC, in the new 65/70 kV version, emits the same quantity of x-ray than the predicate device K080076.

### 8. Conclusions

In light of evidence discussed above and underlining similar technological features for these three compared devices as well as pointing out the compliance with the same safety-related standards and the similar performance as demonstrated by dedicated performance test, the subject device may be found substantially equivalent to the predicate devices K080076, and K120318.
