[2025-10-02T10:26:54.888209] [PI reasoning] **Considering gutta-percha trimming**

I'm addressing a question about how far to trim gutta-percha in a patient with gingival recession, likely relating to endodontic therapy followed by restoration. Due to the recession, the crown margin may be at the root surface. In this case, gutta-percha should typically be trimmed to about 1 mm below the amelocemental junction (ACJ) to ensure that the sealing restoration bonds to dentin rather than gutta-percha. The options on how to position the trim include several specific measurements.

[2025-10-02T10:27:34.531968] [PI reasoning] **Analyzing dental guidelines**

I'm reflecting on how much to trim the gutta-percha in relation to dental structures like the ACJ and CEJ. The ACJ is close to the CEJ, so if the root is exposed due to recession, the ACJ might still be above the gum line, but it could degrade. Although 2 mm is a common recommendation for trimming, the question asks for 1 mm, which I think ensures the barrier material aligns properly at the ACJ.
