This condition is a consequence of abnormalities occurring during the period of tooth eruption. It involves damage to [[Enamel Organ#Ameloblasts|ameloblasts]] (which form [[Enamel Organ#Enamel|enamel]]) in utero, which upsets permanent incisor formation. The [[Enamel Organ#Enamel|enamel]] is marked by pits and lines etc.

In ruminants, damage to [[Enamel Organ#Enamel|enamel]] formation is most often caused by fluoride poisoning and is seen in cattle grazing on pasture contaminated by cement works effluent.
