In the early 20th Century, not long after X-rays were discovered, medical professionals recognized their value as diagnostic tools - they could clearly reveal structures hidden inside the body without the need for risky surgery. Emerging into the 21st century, a revolutionary new technology has entered the diagnostic arena, Cone Beam Computed Tomography (CBCT). CBCT scans have paved the way many dental problems are diagnosed and treated.
Cone Beam CT has some similarities with conventional X-rays, and also with the standard CT scans you would get in a hospital setting. But it's a quantum leap forward in technology and diagnostic precision. For the dentist, it offers the ability to visualize intricate structures inside the mouth, such as root canals, nerves and sinuses (air-filled spaces) — in three dimensions — without surgery. For the patient, it can reduce the need for invasive procedures, shorten treatment time and offer the chance for a better outcome. The detailed diagnostic images that CBCT provides have made it an essential tool in many dental specialties.
X-rays, like visible light, are a form of energy on the electromagnetic spectrum. Just as light makes an image on photographic film (or a digital camera sensor), X-rays can also form an image. The difference is that energetic X-rays can penetrate bone and soft tissue, and reveal its hidden structure by their varying degrees of absorption; in other words, they form a dimensional grayscale picture of what's underneath the surface. Whereas conventional X-rays are limited: like a still-life picture, they show only one perspective on the scene.
