Dentists with extended skills: the challenge of innovation.

Background: The aim was to obtain stakeholders' views on the former London Deanery's joint educational service development initiative to train dentists with a special interest (DwSIs) in endodontics in conjunction with the National Health Services (NHS) and examine the models of care provided.

Methods: A convergent parallel mixed methods design including audit of four different models of care, semi-structured interviews of a range of key stakeholders (including the DwSI trainees) and questionnaire surveys of patients and primary care dentists.

Results: Eight dentists treated over 1,600 endodontic cases of moderate complexity over a two year training period. A retrospective audit of four schemes suggested that first molars were the most commonly treated tooth (57%; n = 341). Patients who received care in the latter stages of the initiative were 'satisfied' or 'very satisfied' with the service (89%; n = 98). Most dental practitioners agreed that having access to such services would support the care of their patients (89%; n = 215) with 88%; (n = 214) supporting the view that DwSIs should accept referrals from outside of their practice.

Conclusion: This initiative, developed to provide endodontic care of medium complexity in a primary care setting, received wide support from stakeholders including patients and primary care dentists. The implications for care pathways, commissioning and further research are discussed.
