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...
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...
A lateral cephalogram is one of the most standardized images in all of dentistry - a skull rendered in exact geometry so that the same points can be found on it year after year. For a century, finding those points was patient handwork with a...
A wall-mounted X-ray head is a fixed instrument, aligned by a stable arm and switched from behind a wall. A handheld unit puts the same tube in one gloved hand and asks the clinician to be both aimer and tripod. The device has become common...
For a single crown, an intraoral scanner is enough. For a full arch of implants, the errors of scanning add up across the span until the bridge no longer fits the bone it was built for. Photogrammetry answers with a different discipline entirely: it does...
A dental radiograph is framed for your teeth, but the exposure does not stop at the enamel. In the same grey field sit the sinuses, the jaw, the airway, the soft tissues of the neck - and now and then, something no one was looking...
Every digital intraoral image begins with a decision made in silicon or phosphor: how to turn an x-ray photon into a number. There are three answers in common use, and each one quietly shapes what the radiograph can and cannot show....
A detection model will read an underexposed, cone-cut, motion-blurred bitewing without hesitation and hand you a confident, tidy result. That composure is the danger. Everything AI concludes about a radiograph is downstream of how well the image was made - and the machine cannot see...
On a medical CT, the number in a voxel is a promise: water reads zero, cortical bone reads a thousand, and the scale means the same thing tomorrow as today. On a cone-beam scan, the same-looking number keeps no such promise - and mistaking one...
