JIMENEZ CASTELLANOS, Fabio Andrés. Sponges with colloidal silver nanoparticles help restore bone lost in endo-periodontal injuries. Rev Cubana Estomatol [online]. 2022, vol.59, n.4, e3589.  Epub 01-Dic-2022. ISSN 0034-7507.


Endo-periodontal lesions can lead to the formation of severe intraosseous defects in the periodontium; which can lead to tooth loss.


Demonstrate that surgical periodontal therapy with the help of gelatin sponges, with colloidal silver nanoparticles, restores bone tissue lost in endo-periodontal lesions.

Case presentation:

55-year-old male patient without systemic alterations, diagnosed with grade 3 endo-periodontal lesion in patients with periodontitis. It was treated first with ducts and then with periodontal surgery combined with gelatin sponges, which contain colloidal silver nanoparticles, and were placed filling the 2-wall bone defect involving > 80% of the root length, with 24 months of radiographic and clinical follow-up.


Based on the case report, surgical periodontal therapy and filling of bone defects with gelatin sponges, which contain colloidal silver nanoparticles, were sufficient to restore the lost bone at a 24-month follow-up. However, further studies are needed to assess the clinical benefit of this material for the treatment of intraosseous defects.

Palabras clave : absorbable gelatin sponge; guided tissue regeneration; periodontal bone loss; regenerative medicine.
