How much attached gingiva is typically assessed on the lingual of tooth #25?

• A. 3mm
• B. 5mm
• C. 7mm
• D. 10mm

Answer: (B)

The typical assessment of attached gingiva on the lingual of tooth #25, which is the mandibular left first premolar, is indeed around 5mm. This measurement represents the distance between the mucogingival junction and the base of the gingival sulcus, indicating the amount of keratinized tissue that is firmly attached to the underlying alveolar bone. Understanding this measurement is crucial for assessing periodontal health and planning any necessary interventions. Adequate attached gingiva is essential for maintaining periodontal stability, and not having enough can lead to increased mobility of the gingival margin and potential recession. Factors such as anatomical variability, individual differences, and overall periodontal health can influence this dimension; however, 5mm is a commonly referenced normative value for the area around this specific tooth.
