Social inequalities in health and oral health continue to present a major challenge to public health. Progress towards the development of interventions to reduce health inequalities is currently being hampered by an incomplete understanding of the causes of inequalities in health. This paper aims to provide oral health researchers with an overview of four current explanations for inequalities in oral health and to suggest further areas of research needed to advance our understanding of the causes of social inequalities in oral health.

Purpose Concerns about psychological well-being (PWB) in doctoral students have grown in recent years. The purpose of this study was to explore qualitatively doctoral students’ perceptions of factors that promoted their PWB during the doctoral journey. Design/methodology/approach Nine recent doctoral graduates at an English university participated in the study. Participants recalled their experience and PWB during the doctoral journey via a life grid and semi-structured interview. The life grids were visually inspected to identify high points in PWB whilst the interview data were analysed thematically. Findings The analysis produced the following seven themes representing factors that participants described during periods of better PWB: accomplishments; intrinsic rewards; self-efficacy; comprehension and understanding; supervisor support; wider support network; and self-care and lifestyle. Originality/value By adopting a positive psychology approach and exploring qualitatively factors that promoted PWB in doctoral students, this study offers an alternative perspective to research on doctoral student well-being, which has largely adopted a pathological focus. As such, the study demonstrates the utility of approaching research on doctoral students’ PWB from a positive psychology perspective. Findings are discussed in relation to the extant literature, and future directions for research are outlined.

A disturbing proportion of dental students report that cheating is acceptable, the majority feel that unacceptable academic practices are not a fair indication of students' ability. The respondents reported that they were unlikely to report the unacceptable working practices of fellow students.
