Pearl vs Subtle Medical
Dentists and dental groups buy Pearl while imaging departments buy Subtle Medical, so each product answers to a different buyer. Pearl's Second Opinion marks caries, bone loss and restorations on dental bitewing, periapical and panoramic films, and its FAQ names DEXIS, Carestream, Romexis, Open Dental and Eaglesoft among its integrations. Subtle Medical says its software is vendor-neutral and offers SubtleHD for MR, PET and CT.
The clearance records read differently. Subtle's About page and openFDA both show eleven, the latest SubtleHD-CT on May 15, 2026. Pearl's home page says 26+ clearances while openFDA lists eight Second Opinion decisions, the latest the panoramic tool on November 14, 2025.
An imaging department weighing SubtleHD(MR) has the vendor's claim of up to 80% faster MRI sequences. A dental group weighing Second Opinion has a 2026 Caries Research comparison of five commercial systems on secondary caries in bitewings, which reported sensitivity from 0.327 to 0.487 across the five systems, Second Opinion included.
