Area of Science:

  • Dental hygiene
  • Oral health research
  • Bacteriology

Background:

  • Previous research indicates powered toothbrushes outperform manual ones for plaque removal.
  • The Interplak and Braun electric toothbrushes are among those studied for efficacy.

Purpose of the Study:

  • To compare the Interplak Home Plaque Removal Instrument and Braun Electric Toothbrush efficacy.
  • Assess supragingival plaque removal and gingival bleeding reduction.
  • Evaluate effectiveness after one-time instruction, reinstruction with one-week use, and third instruction with three-week use.

Main Methods:

  • Examiner-blind study with twelve subjects (six per group).
  • Utilized Turesky Modification of Quigley-Hein Plaque Index and Gingival Abrasion Index.
  • Measured timed gingival bleeding (Barnaby-Muhleman) and probing depths.

Main Results:

  • A statistically significant difference in plaque scores favored the Interplak (p < .05).
  • Both toothbrushes showed effectiveness, but Interplak exhibited superior plaque removal.
  • Gingival bleeding and abrasion indices were also monitored.

Conclusions:

  • The Interplak Home Plaque Removal Instrument is more effective than the Braun Electric Toothbrush for supragingival plaque removal.
  • Powered toothbrushes, particularly the Interplak, offer significant benefits for oral hygiene.
  • Further research with larger sample sizes is warranted.
