This study compared dental hygienists' plaque removal techniques. Combining ultrasonic scalers with floss or using Gracey curettes proved more effective for supra-gingival plaque removal than other methods.

Area of Science:

  • Dentistry
  • Oral Hygiene
  • Periodontology

Background:

  • Effective supra-gingival plaque removal is crucial for maintaining oral health.
  • Various instruments and techniques are used in routine dental hygiene appointments.
  • Assessing plaque removal efficacy without disclosing agents presents a challenge.

Purpose of the Study:

  • To evaluate and compare the effectiveness of different supra-gingival dental plaque removal techniques.
  • To assess plaque removal during routine oral hygiene appointments without disclosing agents.
  • To determine if specific instrument combinations enhance plaque clearance.

Main Methods:

  • 12 dental hygienists performed plaque removal on a single patient using three different instrument groups.
  • Group A: ultrasonic scalers + prophy cups.

  • Group B: ultrasonic scalers + prophy cups + dental floss.
  • Group C: Gracey curettes + prophy cups.
  • Plaque Index (O'Leary) was assessed pre- and post-procedure using UV light and fluorescein.

    • Main Results:

    • None of the tested groups achieved complete supra-gingival plaque removal.
    • Groups B (ultrasonic scalers, prophy cups, and floss) and C (Gracey curettes and prophy cups) demonstrated significantly better plaque removal compared to Group A.
    • The combination of instruments and techniques influenced the efficacy of plaque clearance.

    Conclusions:

    • While complete plaque eradication was not achieved, specific combinations of instruments and techniques improve supra-gingival plaque removal efficacy.
    • Routine oral hygiene appointments can benefit from incorporating dental floss alongside ultrasonic scalers or utilizing Gracey curettes.
    • Further research may explore optimal protocols for plaque removal without disclosing agents.
