• Device Name: C50
• Applicant: Sopro
• Product Code: NBL · Dental
• Decision Date: Dec 14, 2023
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 872.1745
• Device Class: Class 2

Intended Use

C50 is intended for clinical practice of general dentistry, as an aid in the diagnosis of pit and fissure caries, as an aid to highlight dental plaque and gingival inflammations (restricted to gingival inflammations which lead to bleeding upon probing) and as intra-oral camera to visualize anatomical details invisible to the naked eye or with a mirror (thanks to magnification).

Device Story

C50 is an intraoral video camera used by dental practitioners to visualize oral structures and assist in diagnosis. The device uses LEDs to illuminate the inspection site and a CMOS sensor to capture natural fluorescence or standard images. It operates in four modes: CARIO (blue mode) for highlighting potential caries in pits and fissures; DAYLIGHT (white mode) for general visualization; DAYLIGHT+ (white mode) for high-contrast visualization; and PERIO (yellow mode) for highlighting dental plaque and gingival inflammation. Images are converted to a video signal and transmitted via USB to a computer for display. The practitioner uses the screen output to identify clinical conditions, monitor dental hygiene, and show patients 'before' and 'after' care results. The device aids in clinical decision-making by providing magnified views and fluorescence-based detection of pathology. It is intended for use in a clinical dental setting.

Clinical Evidence

Bench testing only. Evidence includes comparative image quality testing (sharpness, resolution, focus), mechanical performance testing of tips and protective sheaths, electrical safety and EMC testing (IEC 60601-1, IEC 60601-1-2, IEC/TR 60601-4-2), photobiological safety (IEC 62471), software validation (IEC 62304), and biocompatibility testing (ISO 10993-1) including cytotoxicity and acute systemic toxicity. All acceptance criteria were met.

Technological Characteristics

Intraoral camera with LED illumination and CMOS sensor. Features four modes: CARIO, DAYLIGHT, DAYLIGHT+, and PERIO. Provides Full HD (1920 x 1080) resolution. Connectivity via USB Type-C to USB-A. Includes automatic or single focus. Materials evaluated per ISO 10993-1. Complies with IEC 60601-1 (safety), IEC 60601-1-2 (EMC), and IEC 62471 (photobiological).

Indications for Use

Indicated for general dentistry patients as an aid in diagnosing pit and fissure caries, highlighting dental plaque, and identifying gingival inflammations that lead to bleeding upon probing; also used as an intra-oral camera for visualizing anatomical details.

| Classification: | NBL |
| Product Codes: | |
| Predicate Device: | K121685 SOPROCARE |
| Device Description: | The C50 is an intraoral video camera equipped with LEDs to illuminate the inspection site. The C50 optics and its complementary metal oxide semiconductor (CMOS) sensor capture the natural fluorescence of the site under observation and convert the images into a video signal that is sent to the computer via a USB interface. The dental practitioner can use the images displayed on the computer screen as an aid in diagnosis. A USB Type-C (camera) to USB-A cable is provided to connect the C50 to a computer. The C50 provides the following functions: Aid in the detection of pit and fissure caries Information about patient dental hygiene Highlighting of dental plaque Highlighting of gingival inflammations (restricted to gingival inflammations which lead to bleeding upon probing) Showing the difference between "before" and "after" care (follow-up). In CARIO mode (blue mode), the camera assists the dental practitioner by highlighting potential carious areas in pits and fissures on the occlusal surface of the teeth. In DAYLIGHT mode (white mode), the camera enables visualization of anatomical details invisible to the naked eye or with a mirror (thanks to its magnification). DAYLIGHT+ mode (white mode) is a shortcut version of DAYLIGHT mode where the contrast has been pushed from 20 to 70. In PERIO mode (yellow mode), the camera helps the dental practitioner to visualize dental plaque, in addition to highlighting areas of gingival inflammation (restricted to gingival inflammation that leads to bleeding upon probing). |
| Indications for Use: | C50 is intended for clinical practice of general dentistry, as an aid in the diagnosis of pit and fissure caries, as an aid to highlight dental plaque and gingival inflammations (restricted to gingival inflammations which lead to bleeding upon probing) and as intra-oral camera to visualize anatomical details invisible to the naked eye or with a mirror (thanks to magnification). |
| Technological Characteristics: | Subject and predicate devices are both manufactured by SOPRO. Predicate and subject device technological and performance characteristics are fundamentally the same, as shown by the following table. The subject device includes a device modification to add an additional mode, DAYLIGHT+ mode. |

Discussion: The modified C50 intraoral camera is very similar to the predicate device SOPROCARE in terms of design, size and weight specifications. Patient contacting materials of the modified and predicate devices are identical in formulation, manufacturing process, processing and geometry.

> The On-Screen Display (OSD) of the C50 allows the device to be used with other imaging software (OIS), including Twain or Sopro SDK integration.

> The subject device C50 offers Full HD resolution instead of the predicate NTSC resolution, thus enhancing image quality. The C50 is connected to a computer by means of a USB cable.

> The C50 intraoral camera is intended for use with legally marketed protective sheaths cleared by FDA as a barrier sleeve for intraoral cameras (product code PEM).
