Background: The aim of this study was to determine whether changes in student selection criteria at The University of Adelaide effected a change in motivation and influencing factors to study dentistry by comparing cohorts. Methods: Online questionnaire completed by first-year dentistry students at The University of Adelaide between 1993-1996 and 1997-2005. Results: All 666 students completed the questionnaire with 647 suitable for analysis. The likelihood of students being motivated for a career in dentistry because it 'fits with family' was greater for the 1997-2005 cohort (OR = 1.68, 95% CI = 1.14-2.49, p < 0.01) than it was for 1993-1996 enrollees, whereas 'status' became less important (OR = 0.47, 95% CI = 0.30-0.73, p < 0.01). Being influenced by a dentist (OR = 2.41, 95% CI = 1.63-3.55, p < 0.001) or a dental employee (OR = 3.19, 95% CI = 0.90-4.85, p < 0.001) was much greater for the 1997-2005 group than it was for the 1993-1996 cohort. Where students came from, parents' level of education and gender were not significant in the multivariate analysis of factors associated with motivation and influences of students' career choice. Conclusions: Changes to the selection procedure were associated with increased emphasis on lifestyle factors and the dental profession, but not with the desire to help people or the importance of the work itself in students' decision to study dentistry.

Background The aim of this study was to explore, using qualitative methods, the intrinsic reasons why dentists work with underserved groups. Minority and marginalized groups of Australians suffer a greater burden of dental disease than the general population due to disparities in accessing care. Recruitment and retention of dentists to care for underserved groups is problematic due to personal, professional and structural reasons. What drives dentists to work with underserved groups is not widely known. Methods Sixteen dentists were recruited using ‘snowball’ purposeful sampling. Semi‐structured in‐depth interviews were conducted. Thematic analysis was conducted on the transcriptions to identify themes. Results Five key themes emerged: (1) ‘tapped on the shoulder’, being personally approached or invited; (2) ‘dental school experience’, the challenges faced as a student; (3) ‘empathic concern’, the non‐judgemental expressions of care toward others; (4) ‘resilience’, the ability to bounce back after setbacks; (5) ‘intrinsic reward’, the personal gain and satisfaction received. This study focuses on the intrinsic rewards which were found to be simple, unexpected, and associated with relieving pain, community engagement and making a difference. Conclusions Emphasizing personal fulfilment and intrinsic reward could be useful when promoting dentistry as a career and when encouraging graduates to consider working with disadvantaged groups.
