Using L-PRF with a papilla preservation technique for treating periodontal defects

Efficacy of the Entire Papilla Preservation Technique With and Without the Use of L-PRF as a Regenerative Material for the Treatment of Infrabony Defects: A Randomized Controlled Clinical Trial

Not applicable Interventional Universidad de los Andes, Chile · NCT06694168

This study is testing if using a special treatment called L-PRF along with a technique to save gum tissue can help people with gum disease heal better than those who don’t receive L-PRF.

What this trial studies

This clinical trial evaluates the effectiveness of using leukocyte and platelet-rich fibrin (L-PRF) as a regenerative material alongside the entire papilla preservation (EPP) technique for treating interproximal intraosseous periodontal defects. The study will compare clinical and radiographic outcomes between patients treated with L-PRF and those treated without it. A total of 30 patients diagnosed with periodontal disease will be enrolled, and their postoperative complications and sensitivity will also be assessed. The goal is to determine if L-PRF enhances the treatment outcomes for patients with significant periodontal attachment loss.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with periodontal disease who have residual probing depths of 6 mm or more after non-surgical therapy.

Not a fit: Patients with underlying health conditions such as uncontrolled diabetes, hypertension, or those on medications that affect healing may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve periodontal regeneration and enhance the quality of life for patients with severe periodontal disease.

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

Eligibility criteria

Inclusion Criteria:

* Patients diagnosed with periodontal disease (loss of interproximal clinical attachment loss in 2 non-adjacent teeth or clinical attachment loss of ≥3mm associated with a PD \>3 mm in two or more teeth) will be included.
* After re-evaluation (6 weeks after non-surgical periodontal therapy) presented residual probing depths equal to or greater than 6 mm.
* Residual pocket is associated with interproximal intrabony periodontal defects of at least 2 walls, with a depth ≥ 3 mm and an angulation ≤ 40º determined on a periapical radiograph.

Exclusion Criteria:

* Patients with an underlying decompensated pathology such as diabetes and hypertension.
* Patients taking medications that interfere with the healing process such as bisphosphonates.
* Patients with diseases that alter bone metabolism such as osteoporosis.
* Pregnant or breastfeeding women.
