About this trial

To date, the quest for ideal biological inductors for periodontal regeneration is still ongoing, especially when facing non-containing defect anatomies. The primary aim of this study is to evaluate the clinical and radiographic performance of a bone graft combined with either enamel matrix derivatives or hyaluronic acid for periodontal regeneration of non-containing intrabony defects in terms of clinical attachment gain (primary outcome) and other secondary outcomes (probing pocket depth reduction, radiographic bone fill). Moreover, this study aims to compare early wound healing and patient-reported outcome measures.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

Diagnosis of stage III-IV periodontitis.

Completed steps I-II periodontal therapy.

FMPS <15% at 3-month re-evaluation.

FMBS <15% at 3-month re-evaluation.

Disqualifiers

Compromised general health which contraindicates the study procedures (ASA III-VI patients).

Systemic diseases/medications which could influence the outcome of the therapy (e.g. uncontrolled diabetes mellitus, non-plaque-induced gingival diseases, antiepileptic drugs (phenytoin and sodium valproate), certain calcium channel-blocking drugs (e.g., nifedipine, verapamil, diltiazem, amlodipine, felodipine), immunoregulating drugs (e.g., ciclosporine), and high-dose oral contraceptives).

Current smokers (self-reported, ≥ 10 cigarettes a day), users of chewing tobacco, and drug/alcohol abusers.

Pregnant or nursing women.

Treatments tested in this trial

  • Hyaluronic acid

    Device

    Minimally invasive flap elevation and debridement of the intrabony defect with micro-curettes. Root surface debridement with ultrasonic debridement with periotip and mini-curettes. Application of cross-linked hyaluronic acid gel composed of a mixture of cross-linked (1.6%) and natural (0.2%) hyaluronic acid (hyaDent BG, Regedent, Germany) through a syringe over a bone xenograft (Smartgraft, Regedent, Germany). The mixture will be then compacted within the intrabony component of the defect.

  • Enamel matrix derivatives

    Device

    Minimally invasive flap elevation and debridement of the intrabony defect with micro-curettes. Root surface debridement with ultrasonic debridement with periotip and mini-curettes. Enamel matrix derivatives gel (Emdogain, Straumann, Switzerland) will be applied on the dry root surfaces and left in place for at least 1 minute avoiding blood contamination. Subsequently, a bone xenograft (Smartgraft, Regedent, Germany) will be compacted within the intrabony component of the defect.
