Objectives: The purpose of this study was to investigate the prevalence of permanent first molar taurodontism and identify the correlation between primary molars and permanent first molar taurodontism. Methods: Among the 10,113 children who underwent panoramic radiography at a dental hospital from January 2010 to December 2019, 685 children (404 boys, 281 girls) were included in this study. Results: Six children (0.8%) and 98 children (14.1%) showed taurodontism of the primary molars and permanent first molar, respectively. All of the children with taurodontism in the primary molars had at least one taurodontism in the permanent first molars. Conclusions: Early diagnosis of taurodontism in primary molars might allow dentists to make treatment plans in accordance with tooth development.
