Abstract

Background: Separated instruments in primary teeth often lead to extraction due to challenges in non-surgical removal, which lacks detailed magnification techniques. Ultrasonics combined with microscopes offer a potential solution; however, their high cost restricts widespread use among dentists. Case: This case report details the effective non-surgical removal of a separated instrument from tooth 85 in a 3-year-11-month-old boy. During a pulpectomy, a #15 K-file was identified as separated. Utilizing a flexible endoscope and an ultrasonic device, the file was successfully extracted without complications. Conclusions: The use of an endoscope represents a cost-effective and practical alternative for dentists, allowing for successful non-surgical retrieval of separated instruments in primary teeth. This method not only preserves the tooth but also reduces the stress associated with such procedures.
