PULPAL REACTIONS - Crown fracture very often involves exposure of the pulp in the young and older animal as the pulp chamber follows the contour of the crown. As the animal gets older there is normally a reduction in the size of the pulp cavity, which is associated with continued deposition of secondary dentine. There are conditions that accelerate the rate of deposition of secondary dentine, thus prematurely reducing the size of the pulp cavity. Attrition and abrasion are two common conditions resulting in a narrow pulp cavity. Injury, orthodontic force and disease can all alter and decrease the pulp chamber and canals. In extreme cases, injury to a tooth will result in the complete obliteration of the pulp chamber and root canals. More unusually, the obliteration is partial, with the pulp chamber retaining the size and shape it had at the time of the injury, and the root canals becoming completely obliterated. On the other hand, injuries that cause inflammation and degeneration/necrosis of the pulp also account for many abnormally large pulp cavities, as dentine production ceases when the pulp is chronically inflamed or necrotic.
