摘要

Aims An analysis of the ranking of dental schools has received limited attention. The aim of this research was to analyse the geographic distribution and socio-economic determinants of the rankings of dental schools.

Methods The recent Quacquarelli Symonds (QS) and Shanghai rankings were analysed for the distribution of dental schools by country, region and income group. The ranking indicator scores were compared by ranking group (top 25; 26–50 and 51+) and matched with the distribution of the top 2% of highly cited dental scientists. Country-level socio-development indicators were compared for countries with a ranked school, no ranked school and no school.

Results In the QS and Shanghai rankings, 63% and 75% of schools were in Europe and North America, respectively. Almost all schools (>90%) were in high-income countries. For QS ranking, scores for academic and employment reputation differed by ranking group; however, citation and H-index were similar. For Shanghai ranking, world-class faculty, world-class output and high-quality research scores differed; however, research impact and international collaboration did not. Research and development expenditure was on average 2% for countries with a ranked school, 0.7% for countries with no ranked school and 0.3% for countries with no school.

Conclusion Being a highly ranked dental school may be reflection of privilege rather than quality. The rankings are biased to research metrics and reputation, rather than the quality of the teaching of oral health professionals.
