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

In dogs, [[Image:enamal-hypoplasia.gif|right|thumb|125px|<small>Enamal (Courtesy of Alun Williams (RVC))<center></center></small>]] hypoplasia may occur following a Canine Distemper Virus (CDV) infection during tooth development . This is a very severe systemic disease seen early in life or in utero in dogs.
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.

== Clinical Signs ==
== Clinical Signs ==
In ruminants, one will see a chalky mottling and yellow brown pitting of [[:Category:Teeth - Anatomy & Physiology|tooth]], due to enamel hypoplasia. There is usually no difficulty in mastication detected and the animal is clinically well.

In dogs, CDV causing enamel hypoplasia, may result in severe discoloration or pitting of teeth due to effect on [[Enamel Organ#Enamel|enamel]] formation.

== Diagnosis ==
Clinical signs are diagnositc, plus history e.g. of CDV in dogs, fluoride in cattle.

== Treatment and Control ==
There is no treatment for this condition. Control measures are prevention of the casues of the disease, e.g. vaccination against CDV and prevention of fluoride poisoning in cattle.
