Appears as clearly demarcated radiolucent line that abuts the thin shelf of very dense bone termed the dental lamina dura.
In the mandible, incisive bone, and rostral maxilla, the lamina dura is more opaque than the surrounding trabecular bone often term the alveolar bone. The caudal maxillary cheek teeth have reserve crown and roots that reside within the rostral and caudal maxillary sinuses.
The radiolucent periodontal ligament and the radiopaque lamina dura are readily evident in the normal horse (Figure 1).
• Because dental disease frequently results in infectious or inflammatory lesions of the sinuses and surrounding bone, these characteristics are pivotal in the accurate identification of abnormal teeth (Figure 2).
In very young horses, the germinal tissue of the teeth appear as wide radiolucent zones with some evidence of radio-opaque dental tissue within the respective bones.< div class='tao-gold-member'>
