title: Maxillary canine displacement; further twists in the tale.
abstract: This report describes two cases seen over a 5-year period, each with a labially impacted maxillary canine found in close proximity to the adjacent first permanent premolar, which had a deviated palatal root. The issue as to whether the premolar root deviation either produced the canine impaction or vice versa is discussed, both with reference to the processes considered to be involved in normal tooth eruption, and to three previously published similar cases.
