Part I of this study described the procedure of electrothermal removal of brackets (ETD) that were bonded on human teeth. The temperature generated at the pulpal wall due to ETD was significantly lower than an established primate threshold. Part II of the study investigated the histologic features of the pulp after ETD. There was some cellular modification that corresponded to placement of the extraction forceps, but there was no evidence of cellular pathosis or modification due to ETD. The data in Parts I and II of this study suggest that ETD is a physiologically acceptable alternative to conventional debracketing techniques.
本研究的第一部分描述了电热去除粘结在人牙齿上的托槽（ETD）的过程。由于ETD在牙髓壁产生的温度显著低于既定的灵长类动物阈值。该研究的第二部分调查了ETD后牙髓的组织学特征。有一些与拔牙钳放置相对应的细胞改变，但没有证据表明存在因ETD导致的细胞病变或改变。本研究第一部分和第二部分的数据表明，ETD是传统去托槽技术在生理上可接受的替代方法。
