Radiographs are used to

• A. help a dentist prevent, monitor and diagnose potential health issues in a patient's mouth
• B. replace clinical exams
• C. diagnose systemic diseases unrelated to mouth
• D. serve as decorative art

Answer: (A)

Radiographs give a view of dental structures that isn’t accessible by sight or touch during a clinical exam. This allows detection and monitoring of problems early, which is how prevention and treatment planning happen. For example, x-rays reveal decay between teeth, bone loss around teeth from periodontal disease, abscesses at the roots, developing or impacted teeth, and the interior anatomy of the roots for endodontic treatment. Because they show these hidden issues, they support preventive care, accurate diagnoses, and ongoing monitoring over time. They are a tool that complements the clinical exam rather than replacing it, and they’re not used to diagnose conditions outside the mouth or for decorative purposes. Therefore, radiographs are used to help a dentist prevent, monitor and diagnose potential health issues in a patient's mouth.
