The postgraduate training course at the Department of Orthodontics of Tokyo Dental College, which started in April 1975, comprises a 3-year curriculum aimed at fostering orthodontic specialists. A system of Accreditation for Orthodontists was introduced by the Japan Orthodontic Society in 1990, since which time, this postgraduate training course has also sought to provide the basic training required to obtain such certification. The purpose of this study was to investigate the demographics of the students on this course and the current work status of its graduates by means of a questionnaire-based survey. The results revealed that, when the fortieth intake of students graduated in March 2017, the total number completing the course had reached 326. The annual mean number of students on this course was 8.2, and recent years have seen a marked increase in the number of women enrolling. In total, 37.5% of the questionnaire respondents had opened orthodontic clinics; 14.8% had opened general dentistry clinics; and 42.6% were working as employees. In addition, 46.2% had an additional place of employment other than their principal place of employment, mainly at a general dentistry clinic. Regarding the field of treatment, 82.4% provided solely orthodontic treatment. We believe that this may because all the responders had completed the postgraduate orthodontics course. The rate of earning accreditation as an orthodontist was high (82.4%), with no difference in the rate of acquisition between men and women. The rate of qualification as a Board-certified orthodontist was 17.9%, with the rate of acquisition by women approximately half of that by men. The number of female orthodontists is rising, and no difference was observed between sexes in the rate of acquiring accreditation as an orthodontist. Women were found to be lagging behind men, however, in regard to the rate of advancement to masters/PHD programs; qualifying as a Board-certified orthodontist; opening an orthodontic practice; and number of days worked. These findings suggest that there are differences in regard to the actual working conditions among the alumni of our postgraduate orthodontic training course, and that these differences are sex-based.
