Enamel trauma

When placing appliances careless use of a band seater can result in enamel fracture. Care is required when large restorations are present since these can result in fracture of unsupported cusps.14 Debonding can also result in enamel fracture, both with metal and ceramic brackets (Fig. 4).15,16 Care must always be taken to remove brackets and residual bonding agents appropriately to minimise the risk of enamel fracture. The use of debonding burs has the potential to remove enamel, especially in air turbine fast handpieces. Care and attention is needed when adhesives are removed.
