An Analysis of Background Factors Influencing Selection of Residency Facility for Dental Students in Universities Located in Rural Areas in Japan

Background: In Japan, since 2006, participation in a 1-year residency programme by all dentists who have passed the National Board Dental Examination has been mandatory. Therefore, a ‘matching system’ has become necessary for dental students in their final year to decide their desired residency facility, but the rate of matching in dental schools located in rural areas is still low. Aim : The principal aim of this study was to elucidate the background factors influencing the selection of residency facilities by dental students in rural areas to facilitate the training of dentists working in local communities. Methods : Using the matching results from 554 final-year students of Kagoshima University Faculty of Dentistry from 2005 to 2013, multiple logistic regression analysis was performed on the background factors of the subjects. Results : Concerning the selection of the residency facility, it was verified that there were strong background factors for subjects to select residency facilities in their hometown, but compared with subjects from other regions, those from Kinki and Kanto regions did not select residency facilities in their hometown. Compared with males, a significantly higher number of females selected residency facilities in their hometown. A significantly higher number of subjects who repeated a school year selected the residency facility of their alma mater. Conclusion : In dental schools of national universities located in provinces, the establishment of a quota system for students from the region, where possible, is one of the most effective steps for securing future dental trainees.
