This open label randomized controlled trial involved 96 adult orthodontic patients. The researchers compared three approaches: receiving verbal instructions, using video aids, or using plaque disclosing tablets. All three groups showed statistically significant improvement in their oral hygiene scores over the four-month follow-up period.
When looking at bleeding and plaque specifically, the group receiving only verbal instructions actually produced higher mean changes in bleeding index compared to the other groups. This suggests that the basic advice given by a professional was highly effective.
No adverse events or serious safety concerns were reported during the study. Three participants declined to continue in the trial. The study authors note that verbal instructions still hold an important part of daily practice. Readers should understand that while new tools like videos exist, standard advice remains a strong option for improving oral health during orthodontic treatment.
