Investigation of supply and demand for dental hygienists in Japan

Abstract

We investigated the current state of employment of dental hygienists in Japan and their supply and demand, including dental hygienists doing procedures and giving instructions in medical and nursing care practice. In addition, we investigated the supply-demand balance for the profession. Analysis was based on the results of national statistic surveys and job postings for which there was recruitment at Osaka Dental University School of Dental Hygienists. The results showed that the number of dental hygienist colleges in Japan increased by nine in the ten-year period from 2010 to 2019, to 163 colleges. We estimated that half of those trained as dental hygienists were not employed in the profession. The number employed increased after age 30, and this trend was especially pronounced after age 50. Although 90% of dental hygienists worked for dental clinics, the number who were practicing in general hospitals and facilities covered by long-term care insurance are increasing considerably. According to the analysis of job postings, the number of recruiting institutions more than doubled from 443 in 2010 to 944 in 2017. In particular, the number of recruiting hospitals rose dramatically from 6 in 2010 to 31 in 2017.

These results suggest that the demand for dental hygienists is growing. This demand can be expected to continue growing with the increase in the recognition of the importance of perioperative oral health management and the needs of nursing care facilities. We found that about half of those who passed the National Dental Hygienist Examinations are not employed as dental hygienists and that the number of employed dental hygienists is slightly lower among those in their 20s compared to other age groups. When considering the future demand for dental hygienists, one important task will be to understand what working conditions enable qualified individuals to contribute to dental health, such as improvement in work-life balance. Also, their education should allow them to use their qualifications throughout life, to incorporate medical and dental care and to promote oral function management for older adults.
