Trauma to a [[:Category:Teeth - Anatomy & Physiology|tooth]] (mechanical, chemical, thermal, infective) often results in [[Enamel Organ#Pulp|pulpal]] inflammation ('''pulpitis''').

Pathology in the area surrounding the apex of a root, i.e. periapical pathology, is most commonly a sequel to chronic pulpitis or pulp necrosis. Initially there is inflammation of the apical periodontal ligament. If untreated, the apical periodontitis progresses to involve the surrounding bone, resulting in destruction of the bone, which is replaced by soft tissue. This is evident as an apical rarefaction on a [[Radiographic Interpretation of Endodontic Disease - Small Animal|radiograph]]. The soft tissue may be granulation tissue (periapical granuloma), cyst (periapical or radicular cyst) or abscess (periapical abscess).

It is important to determine whether the pulp is exposed or not. If there is an obvious pulp exposure this can be diagnosed clinically by visual inspection of the tooth. Occasionally it may not be obvious and [[Oral Examination Under General Anaesthesia|examination under general anaesthesia]] using a [[Dental Explorer|dental explorer probe]] or path finder needs to be performed. This should NEVER be done in the conscious animal as an exposed pulp will be very sensitive.
