The recovery of microbial community after plaque removal depends on periodontal health status. human oral metagenome

By removing plaque with ultrasonic cleaning in patients with different periodontal conditions, and collected supragingival plaque samples at different time points before and after scaling to investigate the similarities and differences of plaque remodeling processes in different periodontal states after scaling, which was helpful for developing microbial targeted therapy to prevent periodontitis and for guiding the prevention and treatment of chronic periodontitis.
