A broken bone or a cracked tooth a quarter-million miles from the nearest hospital is a problem of imaging before it is a problem of medicine. To answer it, NASA's Glenn Research Center has been testing portable, handheld X-ray systems built to work in a...
A panoramic radiograph is ordered to survey the teeth, the jaws, the developing third molars - and along the lower border of the mandible it records something no one asked it to. The inferior cortex of the jaw, that bright ribbon of dense bone at...
A conventional cone-beam scan measures one thing: how strongly each speck of tissue absorbs an X-ray beam. But absorption alone is ambiguous - a sliver of dense enamel and a whisper of metal can cast the very same grey. Spectral, dual-energy CBCT reads two different...
For a century the radiograph told us almost everything about a tooth - and quietly kept one secret. Pressing a three-dimensional root system flat onto a single plane, it overlapped canals, hid the ones tucked directly behind others, and turned a fused, ribbon-like root into...
The intraoral scanner records the mouth as it looks - a flawless colour surface, and nothing beneath it. The radiograph records the mouth as light passes through it - the roots, the bone, the hidden lesion - and almost nothing of the surface. Each is...
Every dental radiograph carries a blur that no detector, no software, and no amount of retaking can fully remove - because the X-ray source is not a point of light but a small glowing area on a metal target, and every point on that area...
For a century, diagnosing decay in a small child's mouth has meant one thing: a clinician, a mirror, a light, and a cooperative patient sitting still long enough to be examined. A 2025 Australian study quietly proposed an alternative. Capture a colour three-dimensional scan of...
Two radiographs of the same tooth, taken months apart, can look identical to a trained eye while a real lesion quietly advances between them. Digital subtraction radiography is the technique that makes that invisible change visible: align the two images perfectly, subtract one from the...
A dental AI tool is only as useful as the door it will open for you. Some vendors publish a documented API and speak DICOM fluently; others hide behind an approved-partner gate you cannot unlock yourself. For anyone whose imaging software holds the radiographs, that...
The most revealing decision a clinician makes about a radiograph is often whether to take it at all. The first ADA and AAOMR patient-selection recommendations in more than a decade - and the first to address cone-beam CT - reframe imaging not as a schedule...
