NCT05541614

Brief Summary

Patients diagnosed with stage III or IV periodontitis that exhibit mandibular first or second molars with increased periodontal probing depth (PPD \> 4 mm) and class II buccal mandibular furcation defects (horizontal probing depth of \>= 3 mm ) will be recruited. This study will be a non-inferiority, prospective, randomized, double-blind controlled clinical trial with a parallel design. Patient will be recruited from the clinics of the School of Dentistry at the Aristotle University of Thessaloniki and private dental practices in Thessaloniki, Greece. Initially, non-surgical periodontal treatment will be performed through scaling and root planning in combination with oral hygiene instructions and motivation. The re-evaluation will be performed 4-6 weeks following the treatment and the patients who meet the inclusion criteria will be included in the study. Patients will be randomly allocated at a 1:1 ratio to either subgingival debridement and flapless application of EMD (test group) into the affected furcation defect or to periodontal surgery in combination with EMD application (control group). Periodontal and radiographic parameters, patient reported outcomes, oral cavity measurements and gingival crevicular fluid will be collected before as well as up to 9 months following the treatment.

Outcome Measures

Primary Outcomes (1)

  • Periodontal probing pocket depth (PPD) change

    Changes in pocket probing depth will be measured using a periodontal probe. The depth of the sulcus will be assessed by gently inserting a graduated periodontal probe until resistance is encountered at the base of the sulcus. The depth from the free gingival margin to the base of the sulcus is measured in millimeters and represents PPD.

    9 months after treatment

Secondary Outcomes (9)

  • Horizontal and vertical furcation involvement change.

    9 months after treatment

  • Periodontal clinical attachment level (CAL) change.

    9 months after treatment

  • Bleeding on Probing (BOP) change

    9 months after treatment

  • Gingival recession (REC) change

    9 months after treatment

  • Furcation involvement grade change

    9 months after treatment

  • +4 more secondary outcomes

Study Arms (2)

Subgingival debridement + Flapless Enamel Matrix Derivative

EXPERIMENTAL

Subgingival debridement following a minimally-invasive non-surgical treatment (MINST) approach with flapless application of EMD Root instrumentation under local anesthesia using mini hand instruments (mini curettes) and ultrasonic instruments with fine tips in the furcation area of mandibular first or second molars with class II buccal furcation defects. EDTA gel will be applied for 2 minutes on the affected root surfaces, followed by rinsing with saline and drying prior to the application of Emdogain® FL. Emdogain® FL has been shown to enhance the early healing of periodontal soft tissue wounds resulting from the instrumentation of periodontal pockets.

Other: Emdogain® FL (flapless Emdogain®) - Enamel Matrix Derivative

Periodontal surgery + Enamel Matrix Derivative

ACTIVE COMPARATOR

Periodontal surgery following a minimally-invasive surgical treatment (MIST) protocol with application of EMD Following local anesthesia, minimal flap elevation on the buccal aspect of first or second molars associated with a grade II furcation defect will be performed.Removal of granulation tissues and root instrumentation with mini hand instruments (mini curettes) and ultrasonic instruments with fine tips in the furcation area will then be carried out. EDTA gel will be applied for 2 minutes on the affected root surfaces, followed by rinsing with saline and drying prior to the application of Emdogain®. Then, the surgical flaps will be positioned and sutured in order to completely cover the defects.

Other: Emdogain® - Enamel Matrix Derivative

Interventions

Emdogain® FL has been shown to enhance the early healing of periodontal soft tissue wounds resulting from the instrumentation of periodontal pockets.

Subgingival debridement + Flapless Enamel Matrix Derivative

Enamel matrix derivative (EMD) has been widely used in the surgical treatment of periodontal disease and in furcation defects.
