Needle breakage during an inferior alveolar nerve block in a child with KBG syndrome: A case report.

BACKGROUND: Needle breakage during the administration of dental analgesia is an extremely rare event. CASE REPORT: A case of needle breakage during the administration of an inferior alveolar nerve block occurred in a child with KBG syndrome. During the injection, a sudden movement of the child caused the breakage of the needle. The next day, the retrieval of the needle was performed surgically under general analgesia. FOLLOW-UP: Three months after the surgery the healing was good. Two years later the child underwent a dental extraction with the aid of nitrous oxide/oxygen analgesia/anxiolysis.
CONCLUSION: Needle fracture is a possible event during the administration of dental analgesia in children.
