title: Indelible bond location marks: an avoidable aesthetic hazard.
abstract: An increasingly popular method of aiding the precise placement of bonded brackets is to identify the long axis and centre of the crown with small pencil marks. A case is reported where marks placed with a soft pencil in the centre of the etched enamel have led to the inclusion of pigment deep in the enamel surface which has proved impossible to remove.
