The main difference between a panoramic X-ray and a full mouth X-ray (FMX) lies in the area of coverage and the level of detail provided.
A panoramic X-ray, also known as a panoramic radiograph or orthopantomogram, captures a wide view of the mouth from one side to the other. It shows the entire mandible (lower jaw), temporomandibular joints (TMJ), upper jaw, and even the nasal sinuses. This type of X-ray is taken outside the mouth and rotates around the patient’s head, creating a 2D image. Panoramic X-rays are commonly used in dental offices as a screening tool to evaluate the overall oral health and identify any potential issues.
On the other hand, a full mouth X-ray, also known as a full mouth series or FMX, provides a more detailed view of the teeth and surrounding structures. It typically consists of a set of 18 to 20 individual X-rays taken using intraoral X-ray sensors or film. These X-rays capture each tooth and surrounding areas from different angles, allowing for a comprehensive evaluation of the teeth, roots, supporting bone, and the overall oral health.
While panoramic X-rays provide a broader view of the mouth, they are not as sharp and detailed as FMX. The panoramic image is more general and does not capture the intricate details of each tooth that can be seen in FMX. Therefore, panoramic X-rays are not typically used for diagnosing specific dental conditions or planning treatments that require precise measurements.
FMX, on the other hand, provides a higher level of detail and is commonly used for diagnosing dental issues such as cavities, gum disease, impacted teeth, bone loss, and other conditions that may not be visible during a visual examination. It allows the dentist to assess the condition of individual teeth, detect any signs of decay or infection, evaluate the position and alignment of teeth, and identify any abnormalities or pathology.
The main difference between a panoramic X-ray and a full mouth X-ray lies in the coverage area and the level of detail provided. Panoramic X-rays show a wide view of the entire mouth, including the jaws and sinuses, but lack the sharpness and detail of FMX. FMX, on the other hand, provides a comprehensive view of each tooth and surrounding structures, allowing for more accurate diagnosis and treatment planning.
