Dental radiographs are primarily used in oral health assessment and treatment planning for which purpose?

• A. Detection of caries and periodontal disease including abscesses
• B. Assessing tooth shade
• C. Measuring tooth size
• D. Evaluating salivary flow

Answer: (A)

Dental radiographs are used to uncover problems that aren’t visible just by looking at the teeth and gums, and this information directly guides what treatment is needed. They reveal hidden decay, including caries between teeth and under old restorations, as well as bone loss and infection at the tooth roots such as abscesses. That combination—decay detection and assessment of the supporting bone and periapical health—provides critical data for planning fillings, crowns, root canal treatment, periodontal therapy, or extractions. Radiographs aren’t used to judge tooth shade, measure tooth size, or assess salivary flow, which are determined by other methods.
