BackgroundProfessionalism is expected of health professionals and advocated by professional regulators in the United Kingdom (UK). Concepts of professionalism have evolved in sociological discourse and its meaning for dentistry is unclear. It is, none-the-less, considered a core domain of dental education and professional practice by the United Kingdom regulator, the General Dental Council. This paper reports the sense-making process, or social process, of professionalism in practice within England.AimTo explore the research question ‘What does dental professionalism mean in practice?MethodsTaking a constructivist grounded theory approach, involving purposive and theoretical sampling, 24 dental professionals were recruited to participate in this qualitative study. In-depth, semi-structured interviews were conducted by one interviewer (AT). Interviews were recorded, transcribed verbatim, and analysed leading to the development of a theory grounded in the data.ResultsA focus on the social-professional constructs used by participants to make sense of their experiences, resulted in a grounded theory where Reconciling Duty emerged as the core category. This represents a process of meeting professional duties to different parties that are often mutually exclusive. It is comprised of three supporting categories: Applying order to the system, where individuals attempt to identify what constitutes professional attitudes and behaviours, Rationalising what is fair, where individuals make judgements on how the conflict between duties should be resolved, and finally Responding to the System, where individuals attempt to actualise these desired resolutions in the context of the complex social system in which they practice. Three dentist archetypes (typologies) emerged, which involved a personal (Type 1), patient (Type 2), or a societal (Type 3) compromise.ConclusionProfessionalism can be conceptualised as process of reconciling multiple, competing, legitimate duties to different parties, in seeking a fair solution. Once this has been identified, individuals need to work within the complex system of dentistry to make their identified outcome a reality. The findings suggest that using the theory of Reconciling Duty helps us to engage with the meaning that the participants drew from the term ‘professionalism’, and anchors it in the lived, everyday professional experiences and challenges faced. A novel typology is proposed, commensurate with calls for a systems approach to the topic.
