概要	Local anesthesia is administered for most dental treatments. Although the development of disposable needles has decreased the incidence of needle breakage, needle breakage in the oral cavity after local anesthesia is a common complication with the potential to cause serious complications, including injury to vital structures in rare cases. Therefore, the needle should be immediately removed if it breaks during surgery. In this report, we present a case of needle breakage during local anesthesia administered for treatment of a right mandibular third molar lesion that was removed one week later. An image examination just before surgery is essential.
