Effectiveness of the Touch-to-Teach Method for Interdental Brushing in Patients With Stage II Grade B Periodontitis.
A study testing Interproximal "Touch-to-Teach" method hygiene care test group in people with Periodontitis and Oral Hygiene, run by Gulf Medical University at 1 site in United Arab Emirates.
Trial summary
In 2018, a collaboration between American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) yielded a new classification system for periodontal diseases and conditions. The new classification categorized periodontitis into stages from I to IV based on the severity of the disease. Read more about this study

About this study
Official title: Effectiveness of the Touch-to-Teach Method for Interdental Brushing in Patients With Stage II Grade B Periodontitis. A Randomized Clinical Trial
In 2018, a collaboration between American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP) yielded a new classification system for periodontal diseases and conditions. The new classification categorized periodontitis into stages from I to IV based on the severity of the disease. Besides the stages, cases were also categorized into A, B and C grades based on the probable progression of the disease. Likewise, cases with interproximal clinical attachment loss of 3-4 mm in the worst affected teeth are considered to be stage II periodontitis.[3] These patients usually do not have tooth loss, can be suffering from localized or generalized type and mostly show horizontal bone loss. There are three types of gingival embrasures. In type I embrasure, the gingival embrasure is filled by the interproximal papilla; whereas in type II and III embrasures interdental papilla loss is seen. Interdental brushing has a vital role in maintaining good oral hygiene and previously published reports have evidenced that successful interdental brushing eliminated interdental plaque below the gingival margin up to 2-2.5 mm. According to the old school of thought, dental floss was advised for type I embrasures, interdental brushes for type II embrasures and unitufted brushes for type III embrasures. Usage of dental floss has been identified to be cumbersome and especially challenging in posterior regions of the oral cavity. Additionally, a recent systematic review in the Cochrane database highlighted the effectiveness of interproximal brushes over dental floss.[9] Recently, the implementation of calibrated interdental brushes use with the availability of interdental brushes with varying sizes, added effectively in creating a healthy interdental papilla in a safe manner. Essentially, a patient-centered and personalized approach named "individually trained oral prophylaxis (iTOP)" has recently been suggested as a solution to remove dental plaque effectively.[10] This concept known as the "Touch-to-Teach" concept provides the patients with an effective method to educate the patients an effective and non-traumatic way of removing interdental plaque.[10] Although, the effectiveness of calibrated interdental brushes showed high efficacy in cases of gingivitis, currently, the effectiveness of these brushes in stage II periodontitis has not been comprehensively studied yet in literature.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Interproximal standard hygiene care control groupProcedure or surgery
The control group was provided with standard oral hygiene instructions (Bass method) and videos regarding maintenance of interdental oral hygiene were provided. Videos regarding oral hygiene maintenance were downloaded from the website of the EFP. Briefly, these animated videos are generated from PerioPixel, which specializes in the generation of animated videos in dentistry, explaining the different oral hygiene techniques and treatments for gingival and periodontal diseases.
Interproximal "Touch-to-Teach" method hygiene care test groupProcedure or surgery
The test group received interdental hygiene care using the "Touch-to-Teach" method. The Curaprox chairside system includes a range of color-coded interdental brushes selected according to the size of the patient's interdental spaces. The brushes are color-coded as blue, red, pink, yellow, and green, with blue with an interdental accessibility diameter of 0.6m, 0.7 mm, 0.8 mm, 0.9 mm, and 1.1 mm respectively. The kit also contains color-coded colorimetric probes (interdental access probes) that can be used to measure the size of the interproximal space.

The record says: finished, as of the sponsor's last update on 2 Jul 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 United Arab Emirates. 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?
Plaque index (time frame: baseline and 3 months). 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 2 Jul 2026.
