Taiwan is facing the problems of the surplus, the uneven distribution, and the urban-rural gap of dental students and practicing dentists. The main purpose of this study was to evaluate the distributions of dental freshmen and practicing dentists in different regions of Taiwan in 2020.We collected the numbers of dental freshmen and practicing dentists in different regions of Taiwan in 2020 for evaluation of their regional distributions in Taiwan and their relationship by the regression analysis.The numbers of dental freshmen and of practicing dentists per 100,000 people in municipalities were higher than those in non-municipalities (P < 0.01 for practicing dentists only). These corresponding numbers in cities with dental schools were significantly higher than those in cities and counties without dental schools, respectively (all P-values < 0.05). In addition, the coefficients of correlation between the dentist index and the dental student index were R2 = 0.7521 (P < 0.05) for municipalities (n = 6), R2 = 0.6332 (P < 0.001) for non-municipalities (n = 15), R2 = 0.9334 (P < 0.05) for cities with dental schools (n = 4), R2 = 0.4925 (P < 0.01) for cities and counties without dental schools (n = 17), and R2 = 0.5025 (P < 0.001) for nationwide (n = 21).The dental freshmen and practicing dentists are still more concentrated in municipalities than in non-municipalities and in cities with dental schools than in cities and counties without dental schools in Taiwan in 2020.
The licensed dentists in Taiwan should join the post-graduate year training program for dentists (PGYD) since 2010. This study aimed to analyze the project types and the geographical distribution of the PGYD training institutions in Taiwan from 2010 to 2018.From 2010 to 2018, 735 hospitals and clinics participated in four types of PGYD project including hospital as the single training institution (project A), clinic as the single training institution (project B), hospital as the main training institution in the joint training group (project C), and clinic as the main training institution in the joint training group (project D). The project types and the geographical distribution of the training institutions were analyzed.The 735 PGYD training projects were proposed by the 735 dental institutions. The project number grew from 119 in 2010 to 195 in 2018. The most common project type was project B (307, 41.8%), followed by the project A (249, 33.9%), the project D (101, 13.7%), and the project C (78, 10.6%). Geographically, these 735 main training institutions were located most commonly in northern region of Taiwan (379, 51.6%), followed by the central region of Taiwan (171, 23.3%), southern region of Taiwan (156, 21.2%), and eastern region of Taiwan (29, 3.9%).Hospital or clinic as the single training institution is the two most common PGYD project types in Taiwan from 2010 to 2018. These single or main dental training institutions are mainly located in the northern, central, and southern regions of Taiwan.
The dentists are the high-risk group of infectious respiratory diseases during dental treatment. This study investigated the changes of the numbers of overall practicing dentists, dental clinics, and hospital dentists in Taiwan during the COVID-19 pandemic.
