Evaluation of a Topical Phenytoin on Gingival Wound Healing

Mehdi Honarparvar

The study aimed to assess the wound healing activity of topical phenytoin on gingival wound healing. In particular, 24 rabbits with the same gender, race and diet were kept in the same environment and were divided into two groups: Twelve for the experimental group and another 12 for the control group. Each rabbit was prepared for surgery. The
study concentrated on the clinical analysis in terms of color, size and gross appearance of the sound. Likewise, it also focused on the histopathological appearance of the wound for 1, 2 and 4 weeks with regard to polymorph nuclear cells, fibroblast and epithelialization. Findings related that in terms of color, no significant differences were observed
during the 1st, 2nd, and 4th week on both control and experimental group A because the pink color was consistently present. Significant improvement in size from the 1st to 4th week of the control and experimental group occurred because significant decrease in size from the 2nd to the 4th week. Meanwhile there was a significant difference in
the gross appearance from the 1st to 4th week of the control group because the edema became normal on the 2nd and 4th weeks. It was therefore finished that the experimental group is effective in 1st week decreasing the size, normalizing the gross appearance, decreasing of polyphonuclear cells and increasing epithelialization. On the other hand, it cannot lessen the fibroblast. Finally effect of experimental is almost same on with control after 4th week.
