The purpose of this double-masked, randomized, controlled trial was to determine if the local application of simvastatin (SIM), combined with minimally invasive papilla reflection and root planing (PR/RP), is effective in improving clinical attachment level (CAL), probing depth (PD) reduction, and increasing interproximal bone height (IBH) in persistent 6–9 mm periodontal pockets in patients receiving periodontal maintenance therapy (PMT).
