Cost Effectiveness of Dental Hygienists
Use of dental hygienists and returns to scale in child dental care in Norway
Wang NJ. Institute of Community Dentistry, Dental Faculty of Oslo, Norway.
The purpose of this study was to investigate, in the provision of dental care for children, technically and economically efficient combinations of dentists and dental hygienists and to study returns to scale by analyzing production functions. Data from 137 dental health clinics were analyzed. Output was registered as the number of 3-18-yr-old children to whom the clinic delivered complete dental care. Resource input was registered as hours spent by dentists, dental hygienists and dental assistants to deliver care to the children. The average clinic that employed dental hygienists used one hygienist hour per three dentist hours for child dental care. It would save dentist time, but not costs, to extent the use of hygienists. Increased use of dental hygienists might be economically efficient if the work distribution between the personnel groups were changed, for example, by delegating more examinations and preventive care to hygienists. There were technical opportunities for further substitution of dental hygienists for dentists both by introducing dental hygienists in the clinics that only used dentists in child dental care and by extending use of hygienists in clinics that already employed hygienists. This study found no productivity gain from centralizing treatment of children in large dental clinics.
