   It's the middle of the night and I can't sleep because I don't understand how panoramic dental imaging machines work. Isn't the spine in the way of imaging the front teeth?

     @Armavica Yes haha you thought it right, the spine gets in the way when imaging the front teeth. The spine appears in the radiograph if you look closely at the area over the front teeth and chin. Because of this, this region loses detail and appears darker, making the panoramic radiograph not the preferred exam for examining the front teeth.
     In fact, the panoramic radiograph is good for having an overview of what's happening, but if you want detail, periapical x-rays are preferred, because the film/sensor is much closer to the teeth, which means more detail and less overlapping

     @Armavica that said, panoramic radiographs are in fact a kind of low radiation dose tomograph where some slices corresponding to the dental arches are overlaped and flatten to look like a 2D image. The x-ray dose doesn't vary during the exam and that's why the spine appears like a shadow over the front teeth and not radiopaque

     @Armavica glad it makes sense to you. I tried my best to explain it using my limited English 😅
