Background:
We aimed to compare the effects of topical zinc oxide and topical silver sulfadiazine in the treatment of partial-thickness burn wounds.
Methods:
The study was conducted with 20 New Zealand rabbits, and burn wounds were created by a brass probe. The animals were randomly divided into two groups. The burns were treated with zinc oxide (Group O) or silver sulfadiazine (Group S) with daily application. The wound healing process was followed both clinically and histopathologically. We determined the days at which 50% and 80% re-epithelization was observed.
Results:
The mean time for 50% and 80% re-epithelization was 21.4 and 25.4 days in Group O and 25.8 and 30.2 days in Group S, respectively (p<0.001). The mean score for wound colonization was lower in Group O. The difference was statistically significant at weeks 2, 3, 4, and 6 (p<0.001). In the histopathological examination, the thicknesses of the epidermis, dermis and scar tissue were 0.12 mm, 3.80 mm and 244 mm in Group O, and 0.16 mm, 4.76 mm and 3.16 mm in Group S, respectively (p<0.001).
Conclusion:
In this experimental burn study, zinc oxide was more effective than silver sulfadiazine in terms of epithelization, dermis maturation and scar formation.
