Dental core training in oral and maxillofacial surgery: a United Kingdom survey of on-call provision.

Introduction Dental core training posts within oral and maxillofacial surgery (OMFS) units often include on-call provision. There is a lack of current data demonstrating the variation of dental core trainee (DCT) involvement in on-call. This variation may influence trainees' experience of training.Aim To examine the provision of on-call cover in OMFS units across the United Kingdom, including trainee involvement, supervision and training.Method Online surveys were distributed in August 2019 to all DCTs, educational supervisors (ESs) and training programme directors (TPDs) in OMFS units to understand trainee involvement in on-call provision, including levels of supervision and perceived educational benefit.Results In total, 167 trainees responded from 69 OMFS units. Responses were received from 102 ESs/TPDs. All trainees experienced on call, with over 75% covering night shifts. Trainees reported minimal difference between support within hours and out of hours (OOH). Qualitative data from trainees and supervisors highlighted the educational value of on-call within normal hours. However, limited supervised training opportunities were reported OOH.Conclusion This survey highlights the educational value of on-call within hours. The perceived level of support does not vary significantly between normal hours and OOH. Some concerns were expressed regarding OOH supervision and prolonged on-call periods.
