Enamel Hypoplasia in a dog's or cat's teeth can be caused by local, systemic, or hereditary factors. Local factors such as periapical inflammation or traumatic injury to a deciduous tooth may lead to Hypoplasia. Febrile disorders during enamel development can interrupt the deposition of enamel, resulting in hypoplastic coronal defects
Before the common use of vaccination, distemper infection was the major cause of this condition. The condition usually affects several teeth. If it is the result of local trauma or systemic pyrexia that resolves within a few days, only those areas of enamel undergoing active formation at the time will be affected.
It is important to restore the teeth that do have Enamel Hypoplasia to protect the pulp and underlying dentin. Restoration is done with composite under general anesthesia.
