Biomaterials in periodontal osseous defects.

Area of Science:

• Periodontology
• Biomaterials Science
• Regenerative Medicine

Background:

• Periodontal diseases often result in osseous defects requiring regenerative treatments.
• Guided tissue regeneration (GTR) utilizes barrier membranes to promote bone healing.
• Evaluating osteogenic potential of biomaterials is crucial for effective periodontal therapy.

Purpose of the Study:

• To clinically assess the osteogenic potential of hydroxyapatite (HA), cissus quadrangularis (CQ), and oxidized cellulose membrane (OCM).
• To compare the efficacy of these materials against normal bone healing in periodontal osseous defects.
• To evaluate their impact on probing depth and attachment levels.

Main Methods:

• Twenty periodontitis patients (20-40 years) with infrabony defects were selected.
• Defects were randomized into four groups: control, HA, CQ, and OCM.
• Probing depth and attachment levels were measured post-surgery, with re-exposure at 6 months.

Main Results:

• All groups showed pocket depth reduction, with a highly significant reduction in the HA group.
• The HA group demonstrated the highest gain in attachment level, averaging 3.2 mm at 6 months.
• Both HA and OCM exhibited favorable outcomes in reducing pocket depth and improving attachment.

Conclusions:

• Hydroxyapatite (HA) and oxidized cellulose membrane (OCM) are effective in reducing periodontal pocket depth and increasing attachment levels.
• These materials show potential for osseous defect fill in periodontal regeneration.
• Future studies should explore combinations of HA and OCM with growth factors and stem cells for enhanced periodontal regeneration.
