The issues of cheating and plagiarism in educational settings have received a large amount of attention in recent years. The purpose of this study was to assess the degree to which academic integrity issues currently exist in the dental schools throughout the United States and Canada. An online survey was developed to gather data pertaining to this topic from two key groups in dental education: faculty and students. Responses were obtained from 1,153 students and 423 faculty members. The results of the survey clearly reveal that cheating is a significant problem in dental schools and that significant differences exist between students' and faculty members' perceptions of academic integrity. The challenge for dental schools is to identify effective strategies to prevent cheating opportunities and to implement and enforce effective means of dealing with specific examples of cheating.
