Objectives: To describe the type of patients seen and work undertaken by dental therapists employed in four personal dental service practices and to report on their cost-effectiveness within the context of the dental practice.
Method: All members of the dental team used a standard day sheet to record all patient contacts and procedures undertaken in that session. Dental therapists recorded data for 30 consecutive sessions and dentists recorded information for 20 sessions. Items were recorded in sufficient detail to allow later matching with the GDS statement of remuneration and a calculation of the average gross fees and patient charges per session.
Results: The role of the dental therapist varied between the practices studied. In two practices the therapist saw a high proportion of child patients, and in one of these this was combined with providing care for a high number of adult patients who were exempt from patient charges. In the two practices where the dental team did not include a dental hygienist, the dental therapist had a relatively high workload providing dental hygiene care for adult patients. It appears that the gross fees and patient charges generated by the dental therapist in all four PDS practices fail to cover the cost of the salary of the dental therapist, dental nurse and associated overheads borne by the practice.
