Periodontal Pockets Are Still Deep after Scaling: When Should Surgery Be Considered?｜證據鏈
In everyday speech, ‘scaling’ may mean routine cleaning that removes only calculus above the gingiva, or it may refer to subgingival instrumentation and root-surface treatment as part of periodontitis therapy. If only the former has been performed, persistent deep pockets do not mean that non-surgical periodontal treatment has failed. If subgingival debridement has been completed by area, the pockets, bleeding and clinical attachment need to be remeasured at an appropriate time before the next stage can be determined. Nor is surgery triggered automatically by a single measurement in millimetres. A newer systematic review of reassessment timing included 29 randomised trials and found that most reductions in pocket depth and improvements in clinical attachment occurred 1 to 2 months after subgingival instrumentation, although further improvement could still occur from 3 to 6 months. If deep pockets remain after reassessment, particularly together with bleeding on probing or suppuration, bone defects, furcations, or root-surface anatomy that restricts debridement and home cleaning, further options can then be compared: repeated non-surgical treatment, flap access for debridement, resective or regenerative surgery, and long-term maintenance.

FAQ
- Does a Measurement of 6 mm after Treatment Mean That Surgery Should Be Scheduled?
- Not necessarily. It is necessary to confirm whether treatment was complete, how long it has been since debridement, whether the site bleeds or suppurates, the attachment and bone-defect conditions, and whether it can be reinstrumented and maintained day to day. Flap treatment produces slightly more mean depth reduction in initially deep pockets, but the evidence does not set a single post-treatment figure as an automatic button for surgery.[F3]
- 治療後に 6 mm と測定されたら、手術を予定するべきですか？ — 必ずしもそうではありません。治療が完全だったか、デブライドメントからどのくらい経過したか、その部位に出血または排膿があるか、アタッチメントと骨欠損はどうか、再びデブライドメントして日常的に維持できるかを確認する必要があります。初期の深いポケットでは、フラップ手術によって平均的に深さがやや多く減少しますが、エビデンスは単一の治療後数値を自動的な手術ボタンとして設定していません。[F3]
