Introductionrofessional behavior is defined as the ability of meeting the ethical expectations of patients. These expectations are based on patients' welfare, independence, and social justice. This type of behavior is determined by commitment to professional duties, adherence to ethical principles, and sensitivity toward patient community (1).One of the main duties of medical universities is to prepare students to comply with professional standards (2). Similar to any other profession, dentistry requires a moral responsibility that is the duty of each dentist and in accordance with his/her obligations under the law (3). Professional behavior emerges during the college years and internship program (4).
