About this study

Official title: Comparison of the Effectiveness of Miswak and Manual Toothbrush in Removing Dental Plaque in Fixed Orthodontic Patients: A Randomized Split-Mouth Clinical Trial

This study compares the immediate plaque removal efficacy of the natural Miswak versus a traditional manual toothbrush using the Modified Bass technique among orthodontic patients. The main question it aims to answer is: Are there statistically significant differences in the post-brushing plaque index reduction between the dental arch side cleaned with Miswak and the contralateral side cleaned with a manual toothbrush?

Read the detailed description

The maintaining of excellent oral hygiene is a significant challenge for patients undergoing orthodontic treatment due to the presence of fixed brackets and archwires, which act as retentive areas for dental biofilm accumulation. While the conventional manual toothbrush is widely prescribed, the natural Miswak (Salvadora persica) serves as a popular traditional oral hygiene tool with documented mechanical and antimicrobial properties. However, there is a lack of split-mouth clinical trials directly evaluating and comparing their immediate mechanical efficacy in the presence of orthodontic appliances.

This study utilizes a split-mouth experimental design to minimize inter-individual variability, where each participant serves as their own control. The mouth of each patient is randomized to use the natural Miswak on one side and the conventional manual toothbrush on the contralateral side during a single clinical session with no subsequent follow-up.

Aim: To evaluate and compare the immediate efficacy of the natural Miswak versus a manual toothbrush (using the Modified Bass technique) in reducing dental plaque scores among a sample of patients with fixed orthodontic appliances at Al-Hawash Private University.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Natural Miswak (Al-Kureysh, Pakistan)Device

    • Preparation: 1-2 cm of outer bark removed, soaked in water for 10-15 mins, and fibers frayed.
    • Technique: Vertical strokes (gum to tooth), horizontal on occlusal, focusing around brackets.
    • Duration: 3 to 5 minutes.
  • Manual Toothbrush (Colgate Zig Zag, China)Device

    • Technique: Modified Bass Technique (bristles at 45-degree angle to gingival margin, short vibratory movements) modified to brush above and below orthodontic brackets.
    • Duration: 3 to 5 minutes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Modified Quigley-Hein Plaque Index (mQH) Score

    Mesial, distal, and mid surfaces of facial and lingual aspects were scored. Scoring was as follows: 0 = no plaque/debris

    1. = separate flecks of plaque at the cervical margin of the tooth.
    2. = a thin continuous band of plaque (up to 1 mm) at the cervical margin of the tooth.
    3. = a band of plaque wider than 1 mm but covering less than one third of the crown of the tooth.
    4. = plaque covering at least one third but less than two thirds of the crown of the tooth.
    5. = plaque covering two thirds or more of the crown of the tooth.
    • Scores from all evaluated surfaces are summed together and then divided by the total number of sites evaluated to provide an average score for each mouth side per patient.
    • Plaque is disclosed using a basic fuchsin solution (VISUPLAC, Maquira, Brazil) applied via micro-applicators.

    Measured: Baseline (immediately before brushing) and Post-intervention (immediately after brushing within the same single clinical session).

Questions about this trial

What is this clinical trial studying?

A study testing Natural Miswak (Al-Kureysh, Pakistan) and Manual Toothbrush (Colgate Zig Zag, China) in people with Dental Plaque and Orthodontic Patients, run by Al-Hawash Private University at 1 site in Syria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Syria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Modified Quigley-Hein Plaque Index (mQH) Score (time frame: Baseline (immediately before brushing) and Post-intervention (immediately after brushing within the same single clinical session).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Sep 2026.
