Abstract

An external root resorption occurred after bleaching and was diagnosed radiographically in a 26-year-old female dental assistant. The resorption was noticed 6 months after bleaching. The involved tooth had no history of trauma. An attempt to stop the resorption by using calcium hydroxide failed. The perforation was corrected surgically with amalgam.
