About this study
Official title: Clinical and Radiographic Changes in Intrabony Defects Following Non-surgical vs. Surgical Minimally-invasive Periodontal Therapy. A Parallel Group, Single Centre, Examiner-blind, Non-inferiority Randomised Controlled Trial
To compare the efficacy of a modified minimally-invasive non-surgical periodontal therapy (MINST) approach with a surgical approach (M-MIST) in determining bone and clinical attachment changes in intrabony defects
Read the detailed description
Periodontal diseases are inflammatory conditions that affect the supporting apparatus of the teeth, including gingiva and alveolar bone. The bone loss resulting from periodontitis often is irregular and localised, giving onset to 'intrabony' or 'vertical defects' affecting one side of the tooth more than the other and more than on the neighbouring teeth. Periodontal intrabony defects have been associated with a higher risk of further progression and eventually tooth loss.
The treatment of periodontitis involves a non-specific reduction of the bacterial load below the gingival margin. This is achieved by oral hygiene instructions (OHI) and non-surgical periodontal therapy (NSPT), aimed at removing calculus and disrupting the plaque biofilm from the affected root surfaces. Intrabony defects are considered sites requiring therapy, often beyond NSPT. Decades ago, intrabony defects were treated with surgical elimination of the defect achieved by sacrificing the adjacent healthy supportive or non-supportive bone. More recently periodontal regenerative procedures have been advocated for deep intrabony defects, which are considered amenable for guided tissue regeneration. This technique results in regeneration of periodontal attachment measurable histologically and radiographically and measurable clinically. However, this is associated with potential morbidity and high costs due to the use of bone graft and barrier materials and is not always predictable. The more recent introduction of minimally-invasive surgical therapy (MIST), modified-MIST (M-MIST) and single-flap approach suggested that the use of biomaterials may not be so crucial for obtaining periodontal regeneration.
Retrospective studies from the investigator's group have shown that minimally invasive non-surgical periodontal treatment of intrabony defects results in clinical improvements (measured as PPD reductions and clinical attachment level-CAL- gain) but also in bone fill of the bony defects, measurable radiographically. The extent of the radiographic resolution of the defect was positively associated with initial defect depth and use of adjunctive antibiotics, while smoking seemed to negatively influence this outcome. A non-surgical minimally-invasive treatment protocol, named MINST, has been proposed along these principles. A more recent retrospective analysis has revealed a reduction in bony defect of nearly 3 mm for cases treated with minimally-invasive non-surgical therapy. The effect of MINST may be mediated by improved blood flow and stable blood clot in the intrabony defect. However, very few studies have been published on MINST and no data are available on the comparison between MINST and MIST.
This is a parallel group, single centre, examiner-blind, non-inferiority randomized controlled trial to compare the effect of a modified minimally-invasive non-surgical therapy (MINST) approach to minimally invasive surgical treatment (MIST) in the healing of periodontal intrabony defects in 66 patients with periodontitis .

Questions about this trial
What is this clinical trial studying?
A study testing MINST, MIST and GTI subgroup (Geometrical/Thermal Imaging) in people with Periodontitis, run by Queen Mary University of London at 1 site in United Kingdom.
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 4 inclusion and 2 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 29 Jun 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 Kingdom. 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?
Radiographic whole defect depth change (time frame: 9 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03797807, which also lists 12 linked publications.
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 29 Jun 2026.
