title: Service-mix in general dental practice in Japan: a survey in a suburban area.
abstract: Overseas investigations have reported the amount and variety of dental services provided. An understanding of the current service-mix in private general practice is important in the anticipation of the future practice of dentistry. The main purpose of this study was to describe the service-mix of private general practitioners in Japan, which was recorded using the Australian Dental Association Dental Procedure Code. Some comparisons with previous studies were offered. The youngest age group and adolescents formed only a small percentage of the total patients, while the greatest percentage of patients occurred in the 45-64 year age group. The services provided were mainly restorative, diagnostic advanced restorative and endodontic services. Preventive services represented a minority of dental activity, especially for young patients. Periodontic and orthodontic services were also remarkable for their low percentage in all age groups. In comparison with an Australian study, the percentage of preventive services was considerably lower. Movement toward a preventive emphasis in Japanese dentistry requires a change in the clinical model, de-emphasizing biomedical and aetiological approaches and placing greater emphasis on the patient and factors affecting dental practice.
