Background:
Intrabony defects resulting from chronic periodontitis can compromise oral health, necessitating regenerative interventions to restore lost periodontal structures. Using bone graft materials like NovaBone and biologics like platelet-rich fibrin (PRF) has shown favorable outcomes. Decortication, a technique that enhances angiogenesis and graft stability, may improve regeneration. This study aimed to assess the clinical and radiographic outcomes of PRF combined with NovaBone putty, with and without decortication, in managing intrabony defects.
Methodology:
A randomized controlled clinical study was conducted on 15 patients with 30 intrabony defect sites. Subjects were divided into two groups: Group I received PRF and NovaBone without decortication, while Group II received the same combination with decortication. Clinical parameters, including plaque index, gingival index, gingival bleeding index (GBI), probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (GR), along with radiographic bone fill, were evaluated at baseline, three months, and six months.
Results:
Both groups demonstrated significant improvements in PPD reduction, CAL gain, and bone fill over time (p < 0.05). Group II showed a greater reduction in GBI (93.33%) compared to Group I (80%). Mean CAL gain was 2.66 mm in Group I and 3.04 mm in Group II. Radiographic assessment revealed greater bone fill in Group II (27.26%) than Group I (20.93%). Changes in GR were minimal and statistically insignificant.
Conclusion:
Combining PRF with NovaBone yields positive regenerative outcomes in intrabony defects, and incorporating decortication offers additional clinical benefits.
