ABSTRACT
Alternative aetiologies include dental trauma, inappropriate trimming and acquired malocclusion, the latter being unlikely given the age. b Management of the condition involves trimming the teeth using a high-speed burr. In cases of congenital malocclusion (and long-standing acquired cases with straightening of the mandibular incisors), this must be done repeatedly, perhaps as often as every 4-6 weeks, as the teeth can never be brought back into occlusion. However, with care this procedure can be achieved without an anaesthetic. The use of nail clippers is contraindicated as this will result in longitudinal fractures, pulp exposure and concussive trauma to the apical germinal tissues.
