What this trial studies

This study evaluates the effectiveness of a bone graft combined with either hyaluronic acid or enamel matrix derivatives for regenerating periodontal tissue in patients with non-containing intrabony defects due to periodontitis. The primary focus is on measuring clinical attachment gain, while secondary outcomes include probing pocket depth reduction and radiographic bone fill. Additionally, the study aims to assess early wound healing and gather patient-reported outcomes to understand the overall impact of the treatments.

Who should consider this trial

Good fit: Ideal candidates are individuals diagnosed with stage III-IV periodontitis who have completed initial periodontal therapy and have specific intrabony defects.

Not a fit: Patients with compromised general health or systemic diseases that could affect treatment outcomes may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve periodontal regeneration techniques, leading to better clinical outcomes for patients with periodontitis.

How similar studies have performed: Previous studies have shown promising results with similar regenerative approaches, suggesting potential for success in this trial.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion criteria:

* 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.
* At least one site with intrabony defects and residual PPD ≥ 6 mm at re-evaluation, with a radiographic intrabony component ≥ 3 mm, and limited to no extension of the defect on the lingual or palatal side as assessed by preoperative bone sounding.
* Intrasurgically, the defect has to present a non-supporting anatomy (1-2 residual walls in its most coronal portion) and it needs to be accessible by flap elevation only on one side (either buccal or oral).
* Signed informed consent.

Exclusion criteria:

* 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.
* Presence of furcation involvement ≥ II degree (Hamp 1975) at the affected teeth.
