What should the patient do if a shadow appears over maxillary teeth in a panoramic image?

When a shadow appears over the maxillary teeth in a panoramic image, it indicates that there may be an issue with the positioning of the patient's tongue during the imaging process. Swallowing and repositioning the tongue allows for better visualization of the maxillary area by moving the tongue away from the upper arch of the teeth. This step is crucial to ensure that the panoramic image captures a clear view of the maxillary teeth without any obstructions.

Proper tongue placement is essential because if the tongue is resting inappropriately, it can cast shadows that obscure important diagnostic information. By swallowing, the patient instinctively moves the tongue upwards, which helps to eliminate any interference during the radiographic procedure. Ensuring the tongue is properly positioned contributes to obtaining a high-quality image, which is essential for accurate diagnosis and treatment planning in dental hygiene and other dental practices.
