Intended Use
Videa Perio Assist is a radiological semi-automated image processing software device intended to aid dental professionals in the measurements and visualization of mesial and distal bone levels associated with each tooth from bitewing and periapical radiographs. Measurements are made available as linear distances or relative percentages. It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The system is to be used by trained professionals including, but not limited to, dentists and dental hygienists.
Device Description
Videa Perio Assist (VPA) software is a cloud-based AI-powered medical device for the automatic measurement of tooth interproximal alveolar bone level in dental radiographs. The device itself is available as an API (Application Programming Interface) behind a firewalled network. The device returns 1) a series of points with connecting lines measuring the mesial and distal alveolar bone levels associated with each tooth 2) this distance expressed in millimeters and/or as a percentage of the root length. Videa Perio Assist is accessed by the trained professional through their image viewer. From within the image viewer the user can upload a radiograph to Videa Perio Assist and then review the results. The device outputs a line to identify these points which calculate the interproximal bone level. The device output will show all applicable measurements from one radiograph regardless of the number of teeth present. If no teeth are present the device outputs a clear indication that there are no identifiable teeth to calculate the interproximal bone level. The intended users of Videa Perio Assist are trained professionals such as dentists and dental hygienists. The intended patients of Videa Perio Assist are patients 12 years and above with permanent dentition undergoing routine dental visits or suspected of having interproximal bone level concerns. Videa Perio Assist may only be used with patients with permanent dentition present in the radiograph.
More Information

Yes
The device description explicitly states that the software is a "cloud-based AI-powered medical device".

No.
The device is described as radiological semi-automated image processing software intended to aid dental professionals in measurements and visualization, not deliver therapy.

No

Explanation: The "Intended Use / Indications for Use" section explicitly states, "It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis."

Yes

The device is explicitly described as "Videa Perio Assist (VPA) software" and "a cloud-based AI-powered medical device". It functions as an API and is accessed through existing image viewers, indicating it is a software component that processes data from external sources (radiographs) and provides output, without including any dedicated hardware.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: Videa Perio Assist is a software device that processes radiological images (X-rays). It analyzes these images to measure bone levels. It does not interact with or analyze biological samples from the patient.
  • Intended Use: The intended use is to aid dental professionals in the measurement and visualization of bone levels from radiographs, not to perform diagnostic tests on biological specimens.

Therefore, Videa Perio Assist falls under the category of a medical device that processes medical images, not an In Vitro Diagnostic device.

No
The provided input does not explicitly state that the FDA has reviewed, approved, or cleared a Predetermined Change Control Plan (PCCP) for this specific device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Bench Testing:
Study type: Non-clinical bench testing.
Sample size: 996 radiographs and 16,131 landmarks.
Standalone Performance:
VPA met pre-specified acceptance criteria on bitewing radiographs with a recall of 94.4% and precision of 84.3%.
VPA met pre-specified acceptance criteria on periapical radiographs with a recall of 91.9%. In the CEJ-ABL subgroup study, participants were more likely to estimate an obscured interproximal bone level point on overlapping teeth and the precision was 79.1%.
Key results: Bench testing demonstrated that the Videa Perio Assist meets performance requirements.

Clinical Testing:
Study type: Clinical Testing.
Sample size: 189 radiographs and analyzed over 2,350 lines.
Standalone Performance:
VPA met pre-specified acceptance criteria on bitewing radiographs with a sensitivity of 92.8%, specificity of 89.4% and mean absolute error below the thresholds.
VPA met pre-specified acceptance criteria on periapical radiographs with a sensitivity of 88.3%, specificity of 87.0% and mean absolute error below the thresholds. All subgroups except for periapical CEJ-ABL, where study participants were more likely to estimate an obscured interproximal bone level point on overlapping teeth, met the pre-specified acceptance criteria.
Key results: Clinical testing demonstrated that the Videa Perio Assist meets performance requirements. No adverse events were observed during the clinical study.

Generalizability:
Statistical analysis by sensors and patient age demonstrated a high level of generalizability in both bench and clinical studies. No sensor manufacturers or models, nor patient age groups, were clear outliers. The device missed acceptance criteria for specificity in Sirona sensors on bitewing radiographs and for 'Patients 61 Years and older' on bitewing radiographs, but this was deemed not a safety or effectiveness concern as it does not impact millimeter accuracy when a prediction is made.

DEVICE DESCRIPTION 4.

Videa Perio Assist (VPA) software is a cloud-based AI-powered medical device for the automatic measurement of tooth interproximal alveolar bone level in dental radiographs. The device itself is available as an API (Application Programming Interface) behind a firewalled network. The device returns 1) a series of points with connecting lines measuring the mesial and distal alveolar bone levels associated with each tooth 2) this distance expressed in millimeters and/or as a percentage of the root length.

Videa Perio Assist is accessed by the trained professional through their image viewer. From within the image viewer the user can upload a radiograph to Videa Perio Assist and then review the results. The device outputs a line to identify these points which calculate the interproximal bone level.

The device output will show all applicable measurements from one radiograph regardless of the number of teeth present. If no teeth are present the device outputs a clear indication that there are no identifiable teeth to calculate the interproximal bone level.

The intended users of Videa Perio Assist are trained professionals such as dentists and dental hygienists.

The intended patients of Videa Perio Assist are patients 12 years and above with permanent dentition undergoing routine dental visits or suspected of having interproximal bone level concerns. Videa Perio Assist may only be used with patients with permanent dentition present in the radiograph.

INTENDED USE/INDICATIONS FOR USE ડ.

Videa Perio Assist is a radiological semi-automated image processing software device intended to aid dental professionals in the measurements and visualization of mesial and distal bone levels associated with each tooth from bitewing and periapical radiographs. Measurements are made available as linear distances or relative percentages.

It should not be used in-lieu of full patient evaluation or solely relied upon to make or confirm a diagnosis. The system is to be used by trained professionals including, but not limited to, dentists and dental hygienists.

SUBSTANTIAL EQUIVALENCE 6.

Comparison of Indications

Overjet Dental Assist and Videa Perio Assist both analyze dental radiographs and measure interproximal bone level. Both devices are only intended as an aid to the trained professional and are not intended to replace the diagnosis by the physician. Both devices are intended to assist dental professionals by identifying and measuring interproximal bone levels on dental radiographs. Videa Perio Assist's Indication For Use includes additional description on the output of the device which is not a safety or efficacy concern.

5

The difference in patient ages does not constitute a safety or efficacy concern as both devices limit use to permanent dentition patients, Videa Perio Assist artificial intelligence algorithm was trained with that patient population and the Videa Perio Assist testing has shown to be safe and effective for patients between the ages of 12 and 22 years of age with permanent dentition present in the radiograph. Likewise the image format differences are not a safety or efficacy concern as Videa Perio Assist has performed all required training and testing with the image formats listed in Table 1.

Conclusion

There are technological differences, as discussed above these differences in technological characteristics do not raise different questions of safety and efficacy. Although the exact definition of a pass or fail for sensitivity and specificity calculations may differ between OverJet Dental Assist and VideaHealth, the results of the bench testing and clinical testing demonstrate that the performance of Videa Perio Assist is comparable to that of Overjet Dental Assist. Both Overjet Dental Assist and Videa Perio Assist met their acceptance criteria and both did not pass a specific subgroup on periapical images where tooth overlap was common. Therefore, Videa Perio Assist can be found substantially equivalent to Overjet Dental Assist.
