This study was undertaken to compare the histopathological healing process of wounds which produced by electrosurgical scalpel and conventional steel scalpel in the gingiva and buccal mucosa of the rabbits. Twelve male and female adult rabbits weighing approximately 2kg. were anesthized with 30mg of seconal injected intravenously. Each wound, about 5mm. in length, was made on the gingiva and buccal mucosa through both modality. The animals were sacrified immediately and at intervals of 1 day, 2 days, 4 days, 7 days, 14 days after the procedures. The tissue specimens were reseated and fixed in 10% formalin solution and embedded in paraffin. All specimens were sectioned serially 6u in thickness and stained with Hematoxylin-Eosin, and examined in the usual methods. Histopathological findings were as follows: 1. All wounds were filled with blood clot which formed by fibrin mesh except for wound made by electrosurgical scalpel on the gingiva. 2. The cells near the wound which made by electrosurgical scalpel were amorphous, with no cellular detail. 3. In wounds made by steel scalpel, healing were processed early and were complete at 14th day. 4. The wounds made by steel scalpel exhibited rapid healing than did the wounds made by electrosurgical scalpel in the both mucosa.
