“…Comparison of medical and dental students across six dimensions of interest (status and security, nature of the occupation, career opportunities, patient care/working with people, use of personal skills and interest in science) by Crossley and Mubarik, [40] suggested that dental students were significantly more likely to be motivated by 'status and security', 'high income' and the 'nature of the occupation', when compared with their medical counterparts; whereas medical students were significantly more likely to be motivated by 'altruism' than dental students. However, the lack of altruism identified in their sample of students is not supported by other studies, [10,41,48,49] and researchers in the field. [50] None of the above studies has examined motivation in relation to all three demographic variables of sex, ethnicity and admission type, which given the changing nature of the profession is an important area for research.…”
