In a patient with swelling at the mandibular angle, what is the next appropriate step?

In a clinical scenario involving a patient with swelling at the mandibular angle, taking an x-ray is the most appropriate next step. This imaging study provides vital information about the underlying causes of the swelling, which could range from dental abscesses to impacted teeth or other pathology involving the jawbone or surrounding structures.

Radiographic evaluation allows clinicians to visualize any bone changes, the presence of asymmetry, or root fractures. Furthermore, it assists in identifying any potential osteomyelitis, tumors, or other conditions that may not be obvious through physical examination alone. This step is essential because the treatment plan, whether it involves extraction, drainage, or antibiotic therapy, will hinge on the specific findings observed on the imaging.

While conducting a physical examination is certainly crucial and should precede most interventions, in this case, an x-ray would provide more definitive data to guide subsequent management. Administering antibiotics might be necessary if there is evidence of an infection, but this should be based on clear clinical findings or imaging results. Immediate extraction may be warranted if a specific tooth is clearly identified as the source of infection or pathology, but the imaging will clarify this decision before proceeding to surgery.
