Case selection criteria included the presence of clinical signs of pulpitis, an intact extracted tooth and availability of a complete history and follow up. Cases where coronal fracture or periodontal pocketing featured were excluded. CT from cadavers with no history of dental disease served as normal controls. Triadan positions and eruption ages of control teeth were matched with those of teeth extracted from cases. CT from selected cases and control teeth were examined occlusally. Secondary dentinal defects were identified and graded. Prevalence of occlusal lesions in CT with pulpitis and controls was compared.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    From the records of 120 horses where exodontia was performed, 40 cases matched selection criteria. Twenty\u2010three mandibular and 21 maxillary CT were extracted from cases. The controls consisted of 60 mandibular and 60 maxillary CT from 7 cadaver skulls. Secondary dentinal defects were significantly over\u2010represented in CT extracted from cases of pulpitis (P&lt;0.001). Of diseased mandibular CT, 56.5% had defects compared to none of the controls. Of diseased maxillary CT, 57% had defects compared with 1.6% of controls. Multiple defective secondary dentinal areas and severe lesions were more prevalent in diseased mandibular CT compared with diseased maxillary CT.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Conclusions and practical significance:<\/jats:bold>\n                    Careful examination of occlusal secondary dentine is an essential component in investigation of suspected pulpitis in equine CT.\n                  <\/jats:p>","DOI":"10.2746\/042516409x464104","type":"journal-article","created":{"date-parts":[[2010,7,30]],"date-time":"2010-07-30T14:30:57Z","timestamp":1280500257000},"page":"30-36","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["The prevalence of secondary dentinal lesions in cheek teeth from horses with clinical signs of pulpitis compared to controls"],"prefix":"10.1111","volume":"42","author":[{"given":"M.
