What is the first step in measuring attached gingiva?

• A. Measure probing depth
• B. Measure GM to MGJ
• C. Measure gingival margin to cementoenamel junction
• D. Measure mobility of teeth

Answer: (B)

The correct answer is to measure the distance from the gingival margin to the mucogingival junction (GM to MGJ). This measurement is crucial because it helps to determine the amount of attached gingiva present. Attached gingiva is the tissue that is firmly bound to the underlying alveolar bone and is critical for periodontal health. By measuring from the gum line (gingival margin) to the mucogingival junction, dental hygienists can assess how much of the gingiva is attached versus how much is unattached or free gingiva. This is particularly important for diagnosing conditions such as gingival recession or for planning periodontal treatments. The other options do not directly assess the amount of attached gingiva. Measuring probing depth focuses on the depth of periodontal pockets but doesn't account for attached gingiva. The measurement from the gingival margin to the cementoenamel junction reflects the health of the gingival tissue but does not provide the necessary information about the mucogingival junction. Lastly, measuring the mobility of teeth assesses periodontal attachment and stability rather than the specific measurement of attached gingiva.
