Basically, the panoramic X-ray is a standard part of orthodontic diagnosis.
Not only the jaw and all teeth with some neighboring regions can be seen on this type of X-ray, but the maxillary sinuses are visible as well. Hidden caries, inflammation of the jaw, and non-developed or impacted teeth are typical findings detected in this way.
The temporomandibular joints are shown, but these findings are only to exclude very rough findings as deformations, fractures or tumors. An exact image diagnosis of the temporomandibular joint with the panoramic X-ray is not possible and usually not necessary. The panoramic X-ray has a very good relationship between cost and benefits, which explains why we use it for initial diagnosis and once again for following the needs of the case for continuing diagnosis.
Basically, with only a few exceptions, we no longer make panoramic X-rays for final diagnosis, so that most treatments can be performed with only two X-rays. This is a considerable reduction in the widespread production of six or more cranial X-rays per orthodontic treatment.
Older panoramic X-ray equipment causes a radiation dose of 25-50 microsievert, which is considered as the normal background radiation at sea level of 5-10 days. In contrast, modern digital devices produce a radiation dose of approximately 10 microsievert, which corresponds to the background radiation of two days. So relatively speaking, it is a small burden for the patient.
