O'Neill TCA. Antibacterial properties of periodontal dressings. J Perio, 46:469, 1975

Purpose

Evaluation of the antibacterial activity of different periodontal dressings:

• Coe-Pack
• Cross pack
• Peripac
• Septopack
• Zinc oxide eugenol based dressing

Materials and Methods

• A survey was made over 6 months
• 430 simple flaps and gingivectomy
• The degree and quality of healing was assessed clinically by the degree of attachment and the presence of absence of granulation tissue when the patient returned after dressing removal after 6-8 days
• Dressings tested with most common bacteria: S. Aureus, S albus, E.C., Pseudomonas Pyocianea, Proteus, Neisseria catharralis, Strepto faecalis. Strepto mitis, Candida albicans

Results and Discussion

None of the dressings showed any antibacterial effect except for the zinc oxide eugenol dressing, which showed some antifungal activity

The authors conclude that the improved healing of the patients who had the dressing intact was due to its physical properties (adhesion), and not by acting as a permeable barrier against saliva and bacteria, and also not to its antibacterial activity.
