Summary

Removing plaque above the gums, through professional cleanings or diligent brushing, improves periodontal health. This also reduces harmful bacteria below the gum line, aiding in dental disease control.

Area of Science:

  • Periodontology
  • Microbiology
  • Preventive Dentistry

Background:

  • Supragingival plaque is a primary etiological factor in periodontal diseases.
  • Understanding subgingival plaque composition is crucial for effective periodontal therapy.
  • Different patient populations may respond variably to plaque removal interventions.

Purpose of the Study:

  • To investigate the impact of supragingival plaque removal on subgingival plaque composition.
  • To assess these effects across various periodontal patient groups.
  • To evaluate the role of different plaque removal methods (professional vs. self-care) in conjunction with periodontal therapies.

Main Methods:

  • Analysis of four studies involving repeated supragingival plaque removal.
  • Inclusion of patient cohorts with chronic periodontitis, periodontal maintenance, and refractory periodontitis.
  • Clinical parameter assessment and subgingival plaque sampling for bacterial analysis using checkerboard DNA-DNA hybridization.

Main Results:

  • Supragingival plaque removal, combined with scaling and root planing or other therapies, improved clinical parameters.
  • Significant reductions in subgingival bacterial species associated with periodontal disease were observed.
  • Meticulous tooth brushing demonstrated comparable clinical and microbial benefits to professional plaque removal.

Conclusions:

  • Effective supragingival plaque removal positively influences periodontal clinical parameters.
  • It beneficially alters the subgingival microbiota composition.
  • Supragingival plaque control is a cornerstone in preventing and managing periodontal disease.
