Premarket evidence — what FDA accepted
source quote (p.4)
“Second Opinion® CS is a computer aided detection ("CADe”) software to aid in the detection and segmentation of caries in periapical radiographs.”
source quote (p.8)
“Utilizes computer vision neural network algorithms, developed from open-source models using supervised machine learning techniques”
Validation studies (2)
Retrospective clinical
n=1,250 images
endpoints: sensitivity of caries detection
Reader study (MRMC)
n=330 images
endpoints: caries detection; anatomical segmentation (enamel, dentin) capabilities; wAFROC-FOM difference; lesion-level sensitivity; False positives per image (FPPI); Surface-level specificity; Localization and segmentation accuracy
Reported performance (6 observations)
source quote (p.10)
“The z-score analysis of the lesion level sensitivity for overall caries detection by image type showed the estimated lesion level sensitivity (95% CI) was 0.88.”
source quote (p.11)
“Aided readers showed a significant improvement in caries detection for periapical images (wAFROC-FOM difference: 0.05, 95% CI: 0.01-0.09, adjusted p=0.0345).”
source quote (p.10)
“The caries subgroup sensitivity (95% CI) was 0.95 (0.92, 0.97) enamel and 0.86 (0.81, 0.90) dentin.”

“Lesion level sensitivity increased significantly (0.20, 95% CI: 0.16-0.25) for enamel (0.19, 95% CI: 0.15-0.23) for dentin.”

Postmarket — what happened after clearance
- re_clearance
The FDA AI/ML device list shows a newer 510(k) K250525 (decision 2025-11-14) from Pearl, Inc. for a matching device line ("Second Opinion® Panoramic") — a new clearance for the same line is a change event.
