Abstract : We could not make a precise diagnosis for complaint of a pain in the maxillary canine area in this patient. After all, tooth in due was the proximal first premolar. The reason of misdiagnosis might be due to that the root canal treatment of maxillary first premolar had ever been performed and the progression was favourable, furthemore, chief complaint of this patient was a pain in the apex area of maxillary canine. At last we found the small cyst on the apex of the first premolar by flap operation for differentiation. As a result of apicoectomy, discomfort was entierely relieved. The pain in the area of canine may have been ‘referred pain’ by first premolar.
