Overjet vs Pearl (2026)
Dental AI's head to head splits on what the algorithm is for. Overjet's distinction is measurement and the payer side: it quantifies caries and periodontal bone loss rather than only flagging them, and it sells a separate claims review product to dental insurers, meaning the same company's AI can sit chairside with the dentist and inside the payer reviewing the claim. Pearl's distinction is detection breadth and reach: Second Opinion highlights up to 18 finding types per radiograph, Second Opinion 3D extends to CBCT, making Pearl by its own account the first dental AI cleared for both 2D and 3D analysis, with pediatric coverage from age four and reported clearance in 120 countries. If your failure mode is disputes over what the image shows and what insurance will accept, start with Overjet. If your failure mode is findings walking out the door undetected across every image type you shoot, start with Pearl. Both hold FDA clearances; neither publishes pricing.
- Quantification over flagging: FDA cleared detection and measurement claims covering caries and periodontal bone loss, with visual overlays presented chairside in real time.
- You want alignment with the payer's reviewer: a separate claims review product used on the dental insurer side, so clinical documentation and claim review can run on the same analytical basis.
- Bone loss numbers, not just highlights: quantified periodontal measurements support perio diagnosis where a detection only overlay cannot.
- Breadth per image decides it: up to 18 finding types per radiograph across bitewing, periapical, and panoramic film, including caries, bone loss, calculus, periapical radiolucencies, and defective restoration margins.
- You shoot cone beam CT: Second Opinion 3D extends the platform to CBCT, per the company the first dental AI with FDA clearance for both 2D and 3D radiologic analysis, plus pediatric caries detection from age four.
- The study evidence is on the record: the panoramic clearance was supported by a standalone performance study and a fully crossed multi reader multi case study, and a published study reported operator diagnostic accuracy rising from 82 to 98 percent with the tool.

Side by Side
Each record in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached. Generated from this pair’s live capability grades, so it moves when a grade moves.
The AI Health Index awards Overjet its top capability grade on AI Centrality and FDA and Regulatory Status. Set against Pearl, Overjet grades higher on AI Liability and Recourse. Its thinnest published disclosure sits on Model Supply Chain Disclosure. Grades reflect evidence the AI Health Index could verify at the last review, so a low grade records disclosure the vendor has not published rather than a capability it has been shown to lack.

Questions buyers ask
Should we choose Overjet or Pearl?
On the axes where the AI Health Index separates them, Overjet grades higher on AI Liability and Recourse, and Pearl grades higher on several axes, including Model Supply Chain Disclosure, Clinical and Operational Evidence and AI Safety and PHI Stewardship. Pearl leads on the greater share of scored axes, but the split means the decision turns on which constraint is binding rather than on an overall winner.
Where do Overjet and Pearl differ most?
The widest separation the AI Health Index records between Overjet and Pearl is on Model Supply Chain Disclosure, where Overjet grades D and Pearl grades B. That axis sits in the AI Capability group, so it should carry the most weight for a buyer whose binding constraint is how much of the work the model itself is trusted to do.
Where do Overjet and Pearl grade the same?
The AI Health Index grades Overjet and Pearl the same on several axes, including AI Centrality, Autonomy and Oversight Model and Model and Technology Transparency. Neither holds an advantage the index can evidence on those axes, so they should not carry weight in a selection between these two.
What have Overjet and Pearl not disclosed?
At the last review, at least one of Overjet and Pearl published thin or absent detail on Model Supply Chain Disclosure. The AI Health Index treats an absent disclosure as a gap in the public record rather than a failure of the product, so these are the axes to get in writing during diligence instead of inferring from the grade.

Pearl's 120 country clearance figure and the 82 to 98 percent accuracy study are vendor published; the multi reader multi case study supported a regulatory clearance and is graded on that basis. Overjet's payer side claims review product means its AI can appear on both sides of a dental claim; practices should understand which of their insurers use it. Neither vendor publishes pricing. Overjet's security certification axis is Not Rated and Pearl's remains unassessed in this index; the side by side below shows the gaps.
