Which diagnostic options should be used for periodontal disease evaluation?

• A. Blood glucose
• B. Blood pressure
• C. Visual inspection
• D. Pocket measurement, Xrays

Answer: (D)

Evaluating periodontal disease relies on combining objective measurements of the supporting tissues with imaging to see bone loss. Measuring pocket depths around each tooth with a periodontal probe provides direct information about pocket formation and, together with gingival recession, yields the clinical attachment level—the key metric for staging and progression. X-ray imaging, such as bitewing or periapical radiographs, shows the amount and pattern of bone loss, helps identify furcation involvement, and reveals calculus or root features not visible on a routine exam. Relying on visual inspection alone misses subgingival pockets and early bone changes, while systemic measurements like blood glucose or blood pressure don’t diagnose periodontal disease on their own, though they may be relevant for overall health and risk assessment. Therefore, a combination of pocket measurement and radiographs gives the most accurate periodontal disease evaluation.
