The aim of the study is to evaluate the efficacy of proanthocyanidins as an adjunctive periodontal therapy in patients with periodontitis. Recently proanthocyanidins were proposed as a viable adjunct to periodontal treatment. Preclinical studies have shown high antibacterial and anti-inflammatory capacities of proanthocyanidins, that could reduce periodontal inflammation and promote periodontal tissues regeneration. In addition, proanthocyanidins demonstrate a specific antibacterial characteristic to attack periodonto-pathogenic bacteria (Porphyromonas gingivalis) but save the oral commensal bacteria (Streptococcus salivarius). Patients with periodontitis (stage III-IV) were included in this study. Patients with periodontitis received two different treatment modalities: minimally invasive non-surgical therapy only (MINST group) or minimally invasive non-surgical therapy and subgingival application of collagen hydrogels with proanthocyanidins (MINST+PACNs group). Clinical periodontal parameters (PPD, CAL, BOP, PI) were evaluated before treatment and after 8 weeks. Concentrations of immunological markers MMP-3 and TIMP-1 in saliva were investigated.
