Abstract
Forty male and female albino rats received a standardized gingival wound (gingivectomy) between the mandibular incisor teeth. One half of the animals received 60 I.U. of d-alpha-tocopheryl acetate daily, administered orally by pipette. An additional control group of 20 animals was not wounded and half of these animals received 60 I.U. of d-alpha-tocopheryl daily. Four animals in each of the two gingivectomy groups (Groups 1, 2) were sacrificed at periods of 1, 2, 4, 7 and 14 days following gingivectomy. Two animals in each of two control unwounded groups (Groups 3, 4) were sacrificed at similar times. Gingival healing was studied grossly and histologically. The animals receiving the vitamin E supplements healed more rapidly, with almost complete restoration of gingiva by 7 days. Complete healing was seen in both control and experimental groups by 14 days. Vitamin E was shown to accelerate gingival wound healing in experimental animals.
