An intraoral radiograph that captures the crowns of the upper and lower posterior teeth (premolars and molars) in a single image. The patient bites on a wing-shaped tab to position the sensor.
It is the gold standard for diagnosing "interproximal caries" (decay between teeth) and assessing alveolar bone height relative to the gum line, which is critical for periodontal diagnosis.
It is a specific X-ray view designed to show the biting surfaces and the spaces between back teeth.
Yes. Modern digital sensors require very low radiation doses (approx. 0.005 mSv), which is negligible compared to annual background radiation exposure.
