Plaque-Induced GingivitisNCT07882459
Individualized Management of Plaque-Related Gingival Inflammation in Routine Dental Practice
A study testing Structured Preventive Care Workflow (iMGi) in people with Plaque-Induced Gingivitis, run by Curaden AG at 1 site in Switzerland.
Trial summary
Gingival inflammation is common and can often be reversed with effective daily oral hygiene. However, preventive care is not always delivered consistently in dental practices, and patients may not receive sufficient individualized training in oral self care and follow-up support.

About this study
Official title: Implementation of a Structured Preventive Care Workflow for Plaque-Related Gingival Inflammation in Routine Practice: A Prospective Study.
Gingival inflammation is common and can often be reversed with effective daily oral hygiene. However, preventive care is not always delivered consistently in dental practices, and patients may not receive sufficient individualized training in oral self care and follow-up support.
This study will evaluate whether a structured preventive care workflow, called iMGi (individualized management of gingival inflammation), can be implemented consistently in routine dental practice.
Read more
Approximately 100 adults with plaque-related gingival inflammation will participate across multiple clinical centres. All participants will receive structured preventive care, including assessment of gingival health, individualized oral self-care training, professional preventive care, and follow-up appointments over approximately 10 months.
The main aim is to understand whether the workflow is practical for dental professionals to deliver, acceptable to patients and practitioners, and consistently applied across different clinical settings.
The researchers will also collect information on gingival bleeding, oral hygiene, patient experiences, and oral self-care behaviour to explore changes during the study.
The findings may help improve how preventive oral healthcare is organized and delivered in everyday dental practice.
Read the detailed description
This prospective, non-randomized, single-arm clinical study evaluates the implementation of a structured preventive care workflow (iMGi) for the management of plaque-related gingival inflammation in routine dental practice.
The study is designed to assess the feasibility, acceptability, fidelity, and reproducibility of the workflow across different clinical settings and dental professionals. It focuses on the integration of established preventive care procedures into a consistent clinical framework rather than testing a new therapeutic intervention.
Approximately 100 adult participants with plaque-related gingival inflammation will be recruited across multiple clinical centres. All participants will receive care according to the same structured workflow, adapted to individual clinical needs.
The workflow integrates clinical assessment, interdental bleeding evaluation using the BOB Index, individualized oral self-care training, plaque disclosure, professional mechanical plaque removal, structured follow-up planning, and digital support for patient communication and self-care.
Following screening and inclusion, participants will attend a baseline visit (T0) and subsequent follow-up visits (T1-T5) over approximately 10 months. The frequency and content of care are structured to support skill development, reassessment, and reinforcement of daily oral self-care.
Implementation will be evaluated through participant completion rates, adherence to predefined workflow steps, and feedback from patients and dental professionals. The primary endpoint concerns completion of the workflow and delivery of the planned steps.
Secondary assessments will explore clinical, behavioural, and experiential outcomes, including changes in interdental gingival bleeding measured using the BOB Index.
The study is conducted under routine clinical conditions, with descriptive analysis of implementation outcomes and exploratory analysis of longitudinal clinical changes. Findings will inform the feasibility of integrating a structured preventive care model into everyday practice and may support the design of future controlled studies.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Structured Preventive Care Workflow (iMGi)Behavioural
A structured preventive care workflow integrating established clinical procedures with individualized oral self-care training and longitudinal follow-up. The workflow includes assessment of gingival health, BOB Index evaluation with calibrated interdental brushes, individualized patient training, plaque disclosure, professional mechanical plaque removal, follow-up planning, and digital support. It is designed to facilitate consistent delivery of preventive care in routine dental practice and does not introduce a new therapeutic procedure.
| Study group | Role | What they receive |
|---|---|---|
| Structured Preventive Care Workflow (iMGi) | Experimental | Participants receive routine preventive dental care delivered according to the structured iMGi workflow for plaque-related gingival inflammation. The workflow integrates clinical assessment, BOB Index evaluation, individualized oral self-care training, plaque disclosure, professional mechanical plaque removal, structured follow-up planning, and digital patient support. All participants follow the same workflow, with assessments from baseline (T0) through T5 over approximately 10 months. Receives: Behavioral: Structured Preventive Care Workflow (iMGi) |

This study will evaluate whether a structured preventive care workflow, called iMGi (individualized management of gingival inflammation), can be implemented consistently in routine dental practice.

The record says: opening soon, as of the sponsor's last update on 20 Oct 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 Switzerland. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Sabina Floridia (+393339119441, sabina.floridia@curaden.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Participant Completion of the iMGi Workflow (time frame: From baseline (T0) to final follow-up (T5), approximately 10 months). The study lists 2 primary outcomes in all. 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 20 Oct 2026.
