Study summary

This randomized controlled clinical trial evaluated whether a single at-home use of a plaque-disclosing tablet, as visual reinforcement following oral hygiene education, provides additional short-term benefits in plaque control and gingival health in children aged 10-14 years.

A total of 53 participants were randomized to a test group or a control group. All participants received plaque disclosure and standardized oral hygiene instruction including the modified Bass toothbrushing technique. Participants in the test group were additionally provided with one plaque-disclosing tablet to use on the fourth day after the initial visit, whereas the control group received no additional intervention. Plaque and gingival indices were recorded at baseline and again at the end of the first week.

  • No use of oral mouthrinse within the previous 4 weeks
  • No previous periodontal treatment
  • No known allergy or to any component of the plaque-disclosing agent

  • Voluntary assent provided by the child

Exclusion criteria

Exclusion Criteria:

  • Presence of any systemic or mental condition that could interfere with participation
  • Antibiotic use within the previous 3 months
  • Use of oral mouthrinse within the previous 4 weeks
  • History of periodontal treatment
  • Known allergy or to any component of the plaque-disclosing agent

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Change in Quigley-Hein Plaque Index

    Plaque accumulation was assessed using the Quigley-Hein Plaque Index at the full-mouth level and separately for the incisor, canine, premolar, and molar regions. Scores were recorded at baseline and at the end of the first week. Lower scores indicate lower plaque accumulation.

    Time frame: From enrollment to the end of treatment at 1 week

Secondary outcomes

  1. Change in Gingival Index

    Gingival health was assessed using the Gingival Index at the full-mouth level. Scores were recorded at baseline and at the end of the first week. Lower scores indicate better gingival health.

    Time frame: From enrollment to the end of treatment at 1 week
