'''Enamel dysplasia''' results from abnormal enamel formation on the crown of the tooth. This occurs when an injury or other disruption occurs during the [[Tooth Development|formation of enamel]]. All enamel formation occurs prior to [[Tooth Eruption|eruption of the tooth]]. The crown formation of the permanent/secondary teeth occurs from the second week postpartum to the age of three months. The crown of the first permanent mandibular molar, however, begins to undergo development and mineralisation prior to birth. Only those areas of the crown undergoing active formation at the time of the injury will be affected, giving the banded appearance sometimes seen. | '''Enamel dysplasia''' results from abnormal enamel formation on the crown of the tooth.
