A 42-year-old woman presented with a persistent radiopacity suggestive of
an apparent root fragment after full dental clearance. This was caused by a
foreign body lying within the buccal soft tissues. The foreign body was
identified as a portion of soda-lime-silica glass which had penetrated
during a road traffic accident but which had remained undetected for 6
years. Following its removal, further chemical analyses were undertaken to
compare the radiographic characteristics of the windscreen glass in this
case with other glass samples.
