Lateral heat production during the use of electrosurgical procedures in the oral cavity causes denaturation of the connective tissue adjacent to the incision line. This study evaluated the denatured zone following electrosurgery incision in dog gingiva with a traditional tungston wire electrode and a no. 15 surgical blade adapted for electrosurgery use. The effects of using a passive electrode during surgical procedures and using an "autosensor" circuit to control power adjustment were also evaluated. It was found that a surgical blade adapted for electrosurgery produces a zone of denatured tissue that is not statistically different from that produced with a wire electrode. Moreover, no differences were noted between incisions produced with manual power adjustment and those with power controlled by the "autosensor" circuit. A significantly wider zone of denatured tissue was produced when incisions were made without a passive electrode in place.
口腔内使用电外科手术时的侧向产热会导致切口线附近的结缔组织变性。本研究评估了使用传统钨丝电极和适配电外科手术的15号手术刀片在犬牙龈上进行电外科手术切口后的变性区域。还评估了手术过程中使用无源电极以及使用“自动传感器”电路控制功率调节的效果。结果发现，适配电外科手术的手术刀片产生的变性组织区域与钨丝电极产生的区域在统计学上无差异。此外，手动调节功率和由“自动传感器”电路控制功率的切口之间未观察到差异。当在没有无源电极的情况下进行切口时，产生的变性组织区域明显更宽。
