Management of residual periodontal pockets using an oscillating chitosan device: A randomized clinical trial

After periodontal therapy, patients with periodontitis may still have persistent periodontal pockets with bleeding on probing, indicating ongoing inflammation. However, retreating these pockets can be unpredictable. This study investigated the effectiveness of a new chitosan brush for treating these pockets. Results showed that its use did not improve all clinical parameters, but significantly reduced bleeding-indicating less inflammation-at the treated sites 6 months after therapy. The absence of bleeding is crucial in preventing disease progression. Maintaining clinically healthy sites during the maintenance phase is essential for long-term positive outcomes and helps reduce the risk of further gum disease progression.
