Abstract:
Objective:To compare the healing of gingiva after electrosurgical gingivectomy with different power outputs and electrodes. Methods:15 rabbits were randomly assigned to 3 groups which used different electrodes: needle electrode, long loop electrode and loop electrode. 1 animal was chosen as control in each group. Free gingiva of anterior teeth had been removed 2 mm in height with different power output and electrosurgical knife. Gingival specimens were harvested for histopathological study on days 1,7,14,and 21 after operation. Statistical analysis was performed on wound healing. Results:Electrical knife with medium power output caused significantly higher degree of inflammation than other techniques(P0.05). Conclusion:When electrosurgery is used on gingiva, there is no significantly difference with different electrodes. Longer observation is needed after gingival electrosurgery with medium power output electrical knife.
