Also known as: Enamel Hypoplasia

Introduction

Enamal (Courtesy of Alun Williams (RVC))

See Enamel Dysplasia

Clinical Signs

In ruminants, one will see a chalky mottling and yellow brown pitting of the tooth, due to enamel hypoplasia. There is usually no difficulty in mastication detected and the animal is clinically well.

In dogs, enamel hypoplasia may result in severe discoloration or pitting of a tooth or teeth due to the effect on enamel formation.

Diagnosis

Clinical signs are diagnostic, 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 causes of the disease, e.g. vaccination against CDV and prevention of fluoride poisoning in cattle.

If only a single tooth is affected, restorative treatment can be performed using dental composites or a metal-alloy jacket crown.
