[2025-10-02T07:45:28.549293] [PI reasoning] **Investigating Kirkland's Uses**

I'm still searching for direct statements linking Kirkland's knife to facial surfaces, and it seems those details are primarily in periodontal textbooks rather than easily accessible databases. For my exam, I can reference the Kaur 2010 article about using Kirkland's gingivectomy knife for de-epithelialization, which indicates its use for facial surfaces. The snippet suggests it effectively removes epithelium across the arch. I'll note the citation as Kaur H. 2010 from the Indian Society of Periodontology. Citing Carranza’s textbook might not be possible.
