BackgroundDental students’ personalities are strongly correlated with their didactic and clinical performances. With the significant changes in the social environment in the past decades, students’ personalities may also change dramatically. Additionally, with the increasing number of international students admitted into US dental programs, educators must pay attention to the potential personality differences between domestic and international students.BackgroundA systematic review focusing on the Myers‐Briggs Type Indicator personality types of dental students was conducted with 11 literature databases following the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guideline. The quality assessment of each included article was conducted following the Joanna Briggs Institute Prevalence Critical Appraisal Tool. Meta‐analyses were conducted for each personality type within the United States in the past 50 years, and in each country in the past 20 years.ResultsEighteen articles (17 reports) were included after the eligibility assessment. The longitudinal trends within the United States showed the predominant two personality types have changed from Extraversion, Sensing, Feeling, and Judging (ESFJ) and Extraversion, Sensing, Thinking, and Judging (ESTJ) to ESTJ and Introversion, Sensing, Thinking, and Judging (ISTJ) during the past 50 years. When comparing different countries, the United States, China, Korea, and Iran have the same two dominant personality types (ESTJ and ISTJ) but not the Philippines (Extraversion, Intuition, Feeling, and Perceiving and Introversion, Intuition, Feeling, and Perceiving). However, there are large variations in the prevalence of other personality types.ConclusionThere have been constant changes in the predominant personalities of dental students over the years. Additionally, understanding the diversity of personality types within the United States as well as among different countries could serve as the foundation for further improvements in teaching strategies and student support services.
