What is the first step to take when encountering a patient with intruded teeth 11 and 12?

The correct first step when encountering a patient with intruded teeth 11 and 12 is to take an X-ray. This imaging technique is crucial because it provides essential information about the extent of the intrusion and the condition of the supporting structures, including the alveolar bone and the periodontal ligament. Intruded teeth may have underlying complications that are not visible during a clinical examination, such as root fractures or damage to the surrounding bone.

By obtaining an X-ray, the clinician can accurately assess the situation and determine the best course of action for treatment. Understanding the vertical position of the teeth, as well as any potential damage to adjacent structures, will inform further steps, whether that be repositioning the teeth, monitoring their status, or considering other treatment options based on the findings. This diagnostic step is fundamental in guiding appropriate management for the patient, ensuring optimal outcomes for the intruded teeth.
