"Re-instrumentation vs Flap Surgery in Residual Pockets: a RCT on Clinical Efficacy"

There are no studies comparing reinstrumentation and flap surgery for the treatment of residual periodontal pockets.

The aim of this RCT is to compare the re-instrumentation vs the flap surgery in terms of PD reduction, CAL gain, gingival recession, need of an additional surgery and pocket closure. Moreover, PROMs will be evaluated

Inclusion Criteria:

• Full-mouth plaque score and full-mouth bleeding score <15% at baseline (re-evaluation) measured at six sites per tooth
• No previous periodontal surgery at the experimental tooth

Exclusion Criteria:

• Connective tissue diseases
• Diabetes
• Pregnancy or lactating
• Furcation involvement
