Effect of Amniotic Membrane Dressing on Pain and Healing of Palatal Donor Site: A Randomized Controlled Trial.

Abstract

BACKGROUND:

Free gingival graft is the most commonly practiced predictable technique for gingival augmentation.

OBJECTIVE:

To assess the effectiveness of human amniotic membrane, a biological dressing, on wound healing and post-operative pain after its application on the palatal donor site after free gingival graft surgery.

METHODS:

Of 27 eligible patients, 15 were randomized into a test group and received human amniotic membrane dressing sutured over their palatal donor site; 12 were randomized into a control group in whom the palatal donor site was only sutured. Standard clinical photographs were taken at 7, 14, and 21 days post-operatively and evaluated by 3 periodontists. The pain score at the donor site was assessed by a visual analog score; the number of analgesics taken was also recorded.

RESULTS:

The mean color match scores were higher in the test group than the control group at 14 (p<0.01) and 21 days after surgery (p=0.02). The difference in tissue texture (p=0.01) and inflammation (p=0.02) between the two groups was only significant on day 14 (p<0.05). The pattern of pain relief was better in the test group compared with the control group, especially in first days, although the differences were not significant in terms of the number of analgesics taken or the pain score.

CONCLUSION:

Application of human amniotic membrane can accelerate wound healing and may decrease post-operative pain and discomfort by a limited amount.
