Objective
To assess the success rate, and the factors which may affect outcome, of vital pulpotomy in cats.

Design
A retrospective, multicentered study

Methods & Materials
Medical records were collated from several referral practices located in North America and reviewed, noting patient signalment, presenting complaint, materials used, and any intra-operative complications. Radiographs from the time of initial treatment, and those from the last available follow-up were evaluated. Treatment outcomes were categorised as successful, no evidence of failure (NEF), or failure according to the endodontic outcome guidelines established by the European Society of Endodontology.

Results (Preliminary)
At the time of writing, treatment was classified as either successful or no evidence of failure in all teeth (100%), with no teeth exhibiting any evidence of failure (0%) radiographically.

Conclusions
Vital pulpotomy in cats appears to have a high success rate when utilising either mineral trioxide aggregate or bioceramic material as a direct pulp capping agent. Vital pulpotomy is a suitable treatment for pulp exposure during crown reduction, and in cases of recent fracture, in the canine teeth of cats. Further studies, ideally prospective in nature, with a larger sample size, and long-term follow-up are required.
