Ingestion of dental mirror fragments: report of case.

A case is reported in which one treated pediatric patient gave his plastic, disposable dental mirror to a 2.5-year-old sibling, who while playing chewed on the mirror and the mirrored glass surface broke in the child's mouth. After thorough examination including x-rays, the patient was released with no further complications. Potentially severe injuries could have occurred, resulting in legal liabilities.
