title: Use of intra-operative ultrasonography to detect a small foreign body in the soft tissue of the upper lip.
abstract: Real-time ultrasonography was used to detect a small foreign body (a broken tip of a barbed broach) which had migrated into the upper lip of a 26-year-old female from the bone defect of the upper canine apex during root canal treatment 10 months previously. Intra-operative use of ultrasound was of great-help in clarifying the positional relationship between the foreign body and the surgical instruments used, and lead to a satisfactory result.
