Circle Cardiovascular Imaging vs Overjet
Overjet's pages sell to dentists and dental service organizations. Vision AI reads bitewing and periapical radiographs for caries, calculus and periapical radiolucency, and CBCT Assist (K251514) covers cone beam. Overjet states a HITRUST certification on its trust page. Two studies of Caries Assist differ: Frontiers in Dental Medicine in 2025 reported sensitivity of 0.69 for enamel and 0.91 for dentin, and the Journal of Dentistry in 2026 measured 56% at the dentin threshold against micro-CT.
Circle's buyer is a cardiology or stroke department reading cvi42 modules for cardiac MR, cardiac CT, vascular CT, interventional planning and electrophysiology. Its logo list includes Mayo Clinic Rochester, Cleveland Clinic and Royal Brompton.
Overjet's buyers and Circle's sit in different specialties, dentists and DSOs on one side and cardiology and stroke departments on the other. Overjet offers a free-trial link and a demo, and Circle lists no public price or license terms.
