title: Electrothermal debracketing. Part II. An in vivo study.
abstract: 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.
