PRF + Minocycline vs Arestin in Non-surgical Perio Therapy

Completed · Phase 4

Conditions studied: Non-surgical Periodontal Therapy

In brief

Periodontitis is a chronic, biofilm-modulated inflammatory disease characterized by microbial dysbiosis and a dysregulated host immune response, eventually resulting in the gradual breakdown of the periodontal attachment apparatus. While non-surgical periodontal therapy (NSPT) remains the first choice of treatment, its capability to completely resolve inflammation and pocketing in moderate disease severity may be limited, supporting the use of adjunctive antimicrobial or biologic interventions. Platelet-rich fibrin (PRF) and locally administered antibiotics, including minocycline, have individually shown clinical advantages; nonetheless, evidence assessing their combined utility remains unexplored. This split-mouth randomized controlled clinical trial (RCT) aims to compare the clinical efficacy of PRF combined with minocycline versus minocycline microspheres hydrochloride (Arestin) as adjuncts to NSPT in patients with Stage II or III, Grade A or B periodontitis.
