About this study
Official title: Non-surgical Treatment of Mandibular and Maxillary Molar Furcations With a Chitosan Brush With Adjunct Enamel Matrix Derivative- a Split-mouth Randomized Clinical Trial
Patients diagnosed with stage III or IV periodontitis who exhibit mandibular first or second molars with Class II, Subclass A, or B buccal and/or lingual mandibular furcation defects (horizontal probing depth of ≥ 3 mm ) will be recruited.
Patients diagnosed with stage III or IV periodontitis who exhibit maxillary first or second molars with Class II, Subclass A, or B buccal furcation defects (horizontal probing depth of ≥ 3 mm ) if furcation involvement on the palatal side (mesiopalatal and distopalatal) does not exceed Class 1 will be recruited.

This study will be a prospective, randomized, single-blinded, controlled clinical trial with a split-mouth design.
Patients will be recruited from the clinics of the Riga Stradiņš University Institute of Stomatology of Riga, Latvia.
Before the baseline treatment, all patients who meet the inclusion criteria will be given detailed oral hygiene instructions and motivation.
Patients' furcation defects in each quadrant will be randomly allocated at a 1:1 ratio to either the application of Oscillating Chitosan Brush with Enamel Matrix Derivatives (test group) or Oscillating Chitosan Brush alone (control group).
Non-surgical periodontal treatment of furcation defects on the test side will be performed through the application of Oscillating Chitosan Brush with Enamel Matrix Derivatives and on the control side with Oscillating Chitosan Brush alone.
The re-evaluation of periodontal status will be performed 12 weeks following the baseline treatment.
Biofilm samples and gingival crevicular fluid (GCF) samples will be taken at the baseline and at 4 weeks.
- Conditions
- Periodontitis, Adult, Furcation Defects, Furcation of Root of Tooth, Periodontitis Complex
- Being tested
- Emdogain® FL, Labrida BioClean®
- Medical subject headings
- Chronic Periodontitis, Furcation Defects

Measured: Baseline, 12 weeks
Furcation Involvement 1
Marker of gain in attachment, Horizontal Furcation involvement measurement using Nabers Probe
- Horizontal loss of periodontal tissue support less than 3 mm
- Horizontal loss of support 3 mm or more, but not encompassing the total width of the furcation
- Horizontal through-and-through destruction of the periodontal tissue in the furcation Lower scores mean a better outcome

Differences in the microbial profile between test and control groups
Measured: Baseline, 4 weeks,
Visual analog scale (VAS)

Questions about this trial
What is this clinical trial studying?
A study testing Emdogain® FL and Labrida BioClean® in people with Periodontitis, Adult and Furcation Defects, run by Riga Stradins University at 1 site in Latvia.
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 9 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: looking for participants now, as of the sponsor's last update on 8 Sep 2025. 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 Latvia. 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. Some participants in this study may receive a placebo. 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 Anete Vaškevica, DDS (+37120202028, anete.vaskevica@rsu.lv), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Modified Bleeding on Probing index (mBoP) (time frame: Baseline, 12 weeks). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
