*'''Enamel dysplasia''' can be caused by systemic diseases (for example, viral infection such as [[Canine Distemper|distemper]]) or trauma during development, and also by hereditary or nutritional factors. Radiographs should be made to determine whether the [[Enamel Organ#Root|tooth root]] [[Tooth Development|development]] was also affected.

*'''Supernumerary roots''' most commonly affect maxillary third premolar teeth in both dogs and cats. Most are not associated with pathology and may be considered a variation of normal. These can be clinically significant if associated with [[Periodontal Disease|periodontitis]], and during extraction or endodontic treatment of the [[:Category:Teeth - Anatomy & Physiology|tooth]].

*'''Dens in dente''', or '''dens invaginatus''', is an infolding of the developing tooth of varying severity that can result in [[Periodontal Conditions|periodontal problems]] and endodontic involvement.

*'''Enamel pearls''' are deposits of [[Enamel Organ#Enamel|enamel]] on the [[Enamel Organ#Root|root]] that sometimes have [[Enamel Organ#Dentin|dentin]] involvement and rarely [[Enamel Organ#Pulp|pulp]] as well. Because the [[Enamel Organ#Periodontal Ligament|periodontal ligament]] cannot attach to [[Enamel Organ#Enamel|enamel]], they may contribute to [[Periodontal Disease|periodontitis]].
