Study summary

The aim of this study is to investigate the clinical efficacy of entire papilla preservation technique with and without the adjunct of amelogenins (EMD) and bone substitutes.

Read the detailed description

The present study is designed as a single-centre, parallel group, randomized, controlled clinical trial comparing the efficacy of EPP with or without biomaterials. Each patient will contribute with a single intrabony defect. Three months after completion of initial periodontal therapy, all the experimental sites will be accessed with the "EPP" technique (Aslan et al., 2017a) and carefully debrided. EDTA gel will be applied on the instrumented root surfaces. A combination of EMD and deproteinized bovine-derived bone substitute will be applied in the test group (EPP EMD + BS), while the control group (EPP) will not receive any regenerative biomaterial. Patients will be enrolled in a stringent maintenance programme with recalls on a weekly basis for the first month and then monthly controls for professional tooth cleaning up to 1 year. Clinical parameters will be recorded immediately before regenerative surgery (baseline) and 12 months after the regenerative periodontal surgery.

    Procedure: Procedure: Periodontal surgery with entire papilla preservation (EPP) technique · Device: EMD application · Device: Bone substitutes application

  • Other
    EPP without EMD+BS

    Using minimally invasive surgery, entire papilla preservation technique without the adjunctive use of amelogenins and bone substitutes

    Procedure: Procedure: Periodontal surgery with entire papilla preservation (EPP) technique

Interventions

  • ProcedureProcedure: Periodontal surgery with entire papilla preservation (EPP) technique

    After local anesthesia injection an modified flap is designed according to minimally invasive microsurgical techniques. After flap elevation, careful removal of granulation tissues from the periodontal defects is performed. Scaling and root planing of the involved dental roots is ensured and finally suture is placed.

  • DeviceEMD application

    Application of Pref-Gel for 2 minutes and then the application of Enamel Matrix Derivatives (EMD) on the surgically exposed root surface.

    Also known as: Amelogenins application

  • DeviceBone substitutes application

    Following the application of EMD, filling the bone defect with bone substitutes.

What researchers measure

Primary outcomes

  1. Clinical attachment level (CAL) gain

    CAL is measured as the distance between cemento-enamel junction and the tip of the periodontal probe

    Time frame: 1-year

Secondary outcomes

  1. Post-surgical discomfort

    Post-surgical discomfort will be measured on a visual analog scale (VAS) and reported in millimeters. The subjects will be instructed to mark their level of pain on a line. The average change in discomfort level will be determined and compared between the two arms. A visual analogue scale (VAS) of 100 mm long will be used to evaluate the degree of discomfort (0=no pain/hardship; 100=unbearable pain/hardship).

    Time frame: 1-week after surgery
