[[:Category:Teeth - Anatomy & Physiology|Teeth]] are divided into the [[Enamel Organ#Crown|crown]], neck and [[Enamel Organ#Root|root]]. The radiopaque structures of the tooth are mostly [[Enamel Organ#Dentine|dentin]] covered by a thin layer of radiodense [[Enamel Organ#Enamel|enamel]] (incompletely visualized on a radiograph) and [[Enamel Organ#Cementum|cementum]] which is less dense than dentin and only really visible if it has undergone hyperplasia. The internal radiolucent area is the [[Enamel Organ#Pulp|pulp cavity]] – it extends into the crown and down to the apex of the root. As the tooth matures, more dentin is laid down and the pulp size reduces with age. An immature tooth can be present in a mature animal where early trauma has caused pulp necrosis and thus stopped further development of the tooth. The tooth is attached to the boney socket by the [[Enamel Organ#Periodontal Ligament|periodontal ligament]]. The periodontal ligament space appears as a thin radiolucent line of uniform width between the root and bone. The cortical bone on the alveolar ridge appears as a radiopaque line of uniform thickness known as the lamina dura. The alveolar bone should extend to the cementoenamel junction.
