Why dental X-rays are necessary and how are they different? Patients often come to the dentist with dental X-rays that have been taken a year ago or even earlier. To make an accurate dental diagnosis, it is essential to see what is the current situation in the mouth. In one year, a tooth can easily change from healthy to damaged. Tooth decay can start between the teeth or in the root of the teeth where the canals were filled, or cysts may also form. Therefore, the X-rays should be no older than 6 months. Another issue with conventional (film or digital sensor) X-rays is that they provide little information and can help diagnose the condition of 1-2 teeth. Therefore, it is difficult to draw up an accurate treatment plan. A panoramic dental X-ray is a two-dimensional, 2D X-ray image, hence, there are distorted areas, some are stretched and others are overlapping. Consequently, it is not always possible to see additional root canals or inflammation at the apex of the root. It is also not possible to assess bone thickness and density before implant placement. Panoramic X-rays allows general information about the oral cavity to be obtained. A 3D X-ray is a three-dimensional X-ray image, the 3D system X-ray is displayed in three-layer projections, without any distortion, in a 1: 1 ratio. Accordingly, it is possible to assess the condition of teeth and tissues with surgical precision. Therefore, the patient needs a 3D X-ray for their own benefit.
