摘要

A 2-year-old domestic feline patient was presented for evaluation of a complicated crown fracture of the right maxillary canine tooth. Clinical and radiographic examination revealed a non-vital immature permanent canine tooth with an open apex. This case report describes a two-visit technique using mineral trioxide aggregate in an apical barrier method for the treatment of a non-vital immature permanent canine tooth in a cat.
