This study explored, and compared, the attitudes of student groups trained at the University of Portsmouth Dental Academy (UPDA) in 2010/2011 towards dental interprofessional education (IPE). The study population consisted of fifth-year student dentists (n = 80) from King's College London Dental Institute, second- and third-year dental hygiene and therapy (n = 38) and first-year dental nursing (n = 14) students from UPDA. A 19-item, validated and dentally modified questionnaire, 'Readiness for Inter-Professional Learning Scale (RIPLS)', was administered. RIPLS contains three subscales: teamwork and collaboration, professional identity and roles and responsibilities. Mean (x¯) and standard deviation (SD) of the scores were calculated, following reversal of negative items. All the analyses were carried out using SPSS version 20 and STATA version 11. An overall response rate of 71% (n = 94) was achieved. In reference to teamwork and collaboration, all groups strongly indicated that IPE can contribute to learning teamwork skills (x¯ = 24.98, SD = 3.5) and improving relationships with team members (x¯ = 12.93, SD = 1.63); however, the scores did not differ between the groups (P = 0.09 and P = 0.16, respectively). Concerning professional identity, student dentists had significantly higher preference for a discipline-based approach (P = 0.002); were more likely to agree that 'it is not necessary for undergraduate dental and dental care professional students to learn together' (P = 0.01); and perceived that 'clinical problem-solving skills can only be learnt effectively with other students from their own discipline' (P = 0.02) than dental hygiene and therapy students. In relation to roles and responsibilities, participants demonstrated a strong sense of their own professional role. Student dentists reported that they had 'to gain more knowledge and skills' than dental hygiene and therapy (P = 0.01) and dental nursing (P = 0.01) students. Dental hygiene and therapy students were less likely than student dentists to agree that 'the role of dental nurses and hygienists was to mainly provide support for dentists' (P = 0.001). The findings suggest that IPE was perceived as beneficial in relation to teamwork; however, the study raises issues regarding professional identity and roles. Educators should consider differing perceptions of professional roles and identities when planning and delivering interprofessional programmes.
