Assessment of Vital Pulp Therapy for Nine Complicated Crown Fractures and Fifty-Four Crown Reductions in Dogs and Cats

Abstract

Subjective owner assessment of the success of vital pulp therapy was performed for complicated crown fracture (n = 9) and crown reduction (n = 54) of canine teeth in dogs and cats. Our results documented that owners are not able to accurately determine the outcome of vital pulp therapy. Objective assessment of vital pulp therapy for teeth receiving crown reduction indicated maintenance of vitality in 28 of 28 (100 %) teeth. Subjective and objective assessments of vital pulp therapy performed > 7-days following complicated crown fracture indicated 9 of 9 (100 %) teeth were non-vital. A poor prognosis for maintenance of tooth vitality is warranted for vital pulp therapy of complicated crown fractures with prolonged pulp exposure regardless of the age of the patient. Whereas, an excellent prognosis can be provided for vital pulp therapy following crown reduction. Semiannual, postoperative oral and radiographic examinations are recommended for a minimum of 2-years to assess vitality in all teeth receiving vital pulp therapy.
