Which procedure involves the removal of necrotic tissue from the lining of a periodontal pocket?

The procedure that involves the removal of necrotic tissue from the lining of a periodontal pocket is gingival curettage. This technique focuses specifically on the debridement of soft tissue affected by periodontal disease, targeting the inner lining of the periodontal pockets to remove diseased and necrotic tissue. By eliminating this unhealthy tissue, gingival curettage aids in reducing inflammation and promotes healing within the periodontal environment.

This procedure is distinct from other options, as root planing involves smoothing and shaping the root surfaces of teeth to facilitate better reattachment of the tissue, while prophylaxis refers to preventive care performed to maintain oral health and prevent disease. Coronal polishing, on the other hand, is a cosmetic procedure aimed at polishing the surfaces of the teeth to enhance their appearance and remove stains but does not address periodontal pockets or necrotic tissue specifically. Therefore, gingival curettage is the precise method for addressing and removing necrotic tissue within periodontal pockets.
